Guide To Help Understand The Wattage Spec Of Contemporary Audio Amplifiers

By Gunter Fellbaum

Looking at some of the technical specs of today's power amplifiers, one cannot help but be at a loss in trying to compare different models and terms, such as "t-amp", "THD" etc. I will give a short overview of the output power spec in order to help you better understand the meaning of this term and how they relate to the performance of an amplifier.

If you are looking to buy an audio amplifier to set up your home speakers, you will often be confronted with a number of strange terms describing its performance. But how do these numbers relate to how the amplifier sounds and how are these to be interpreted? Let me now go ahead and explain the wattage rating of audio amplifiers.

"Wattage" is sometimes also known as "Power" or "amplifier output power". To put it in a nutshell, "wattage" relates to how high the amp can drive your speakers. The higher this number the louder your speakers. You want to pick the amplifier wattage based on how large your listening environment is. For best audio quality, you may want to go with an amp that has higher power than you need since many amps will show increasing distortion as the audio power goes up.

There are two common ways to display amplifier wattage. These are "peak power" and "rms power". "Peak power" describes how much power the amp can deliver to your speakers for a short burst. On the other hand, "rms power" describes how much power the amp can output for a prolonged amount of time without being damaged. The peak power rating in the past often led to manufacturers showing large wattage ratings for small amplifiers. However, in reality those amps would not be able to sustain larger amounts of output power for larger amounts of time.

Today most amps will specify rms power which gives a better indication of the amps true performance. However, please ensure that your amp has enough headroom to avoid clipping of the audio. Having enough headroom is essential since music signals differ a great deal from sine wave signals which are used to measure rms power. Short bursts of high power are often found in music signals. These bursts will drive the amp into high distortion unless the peak power is high enough.

Please note that often the peak power of the amp will depend on the impedance of your speakers which is typically between 4 and 8 Ohms. Due to the limited amplifier supply voltage, the maximum output power will be half if you connect an 8-Ohm speaker of the peak power that the amp can deliver to a 4-Ohm speaker. Usually maximum power is specified for a 4-Ohm speaker impedance. However, ideally the manufacturer will tell which speaker impedance the power rating is being referenced to. Please note that some amplifiers cannot drive speakers with very low speaker impedance.

Some Crucial Details To Understand Regarding Wireless Loudspeakers

By Gunter Fellbaum

Picking the perfect type of wireless outdoor speakers is difficult when confronted with a large array of different terms and specifications, such as "sound pressure level", "output power" etc. You may not even fully understand the most basic of these terms, such as "speaker output power". In this article, I will have a closer look at one of the most fundamental of these terms: speaker output power. This term is also known as "speaker wattage".

Some of the terms which speaker manufacturers publish often are misleading and do not necessarily give a good indication of the actual performance of the speaker. Next I will explain the "wattage" spec of speakers. This spec is one of the most basic and perhaps important specs to understand.

"Wattage" shows how loud your speaker can sound. Depending on your application, you can go with a small speaker tolerating only a few watts or a larger one tolerating several hundred watts. Many smaller home speakers only can be driven with a few watts power which usually is enough for a small room. If you plan to shake your walls then you obviously want to opt for a speaker that has up to several hundred watts. Please note that many speakers will start distorting the audio once the audio reaches higher wattage. If you want to enjoy low-distortion audio then you may want to pick a speaker which will give you more wattage than you will actually need.

Wattage is either given as "Watts peak" which means the speaker can tolerate short burst of this amount of power or "Watts rms" which shows how much power the speaker can tolerate for a longer period of time. The peak rating has been somewhat abused by vendors stating enormous peak audio power while their speakers are in fact tiny and unable to handle more than just a few watts rms power.

Music and voice is not constant in terms of loudness. As such the peak power rating is still important, although not as important as the rms power rating. Ideally the speaker will show both the rms and peak power rating. Having a high peak power rating will ensure enough headroom for power peaks which are common in music signals. Having enough headroom is essential since music signals differ a great deal from sine wave signals which are used to measure rms power. Short bursts of high power are often found in music signals. These bursts will drive the speaker into high distortion unless the peak power is high enough.

However, be aware of the fact that the maximum output power also depends on what type of speakers you are using, in particular the impedance of the speakers. Speakers usually have impedances between 4 and 8 Ohms. Due to the limited supply voltage of your amplifier, the maximum output power will be half if you connect an 8-Ohm speaker than the peak power that the amp can deliver to a 4-Ohm speaker. Thus often maximum output power is given for a specific speaker impedance.

Things To Look Out For When When Searching For The Perfect Stereo Amplifier

By Gunter Fellbaum

Audio amplifiers are available in a flood of different technologies and models. Choosing the perfect model for a particular application seems to be a daunting task. I will explain some basic amplifier terms and help you pick the best model no matter what your particular application might be.

Some audio sources such as surround-sound receivers already come with a built-in audio amplifier. Using a separate amplifier, however, offers some advantages. One advantage is having more flexibility and being able to pick an amplifier that is best suited to drive a particular speaker. Some of today's mini amplifier models can be hidden virtually anywhere due to their small size.

When picking an amplifier, your first consideration probably is the amplifier output wattage. You will need a high wattage if you are driving speakers with a low sensitivity (expressed in dB/W), for driving speakers in large rooms or for outdoor speakers. Don't overdrive your speakers though since this can irreparably damage your speakers.

But don't be overly concerned about wattage. An amp supplying 20 to 50 Watts will give you more than plenty of power to sufficiently drive a speaker in any but the largest room.

There are two conventions for specifying amplifier wattage. The first one specifies how much power the amplifier is able to deliver continuously. That number is often called rms or continuous power. The second number is called peak or maximum power and tells how much the amp can deliver for short bursts. Typically you should select an amplifier based on rms power. However, make sure that the amplifier has sufficient headroom or peak power to avoid clipping of music signals.

However, audio quality is just as important as having enough audio power. Therefore be sure to also look at factors related to the quality of the amplifier. One of these parameters is called total harmonic distortion or THD. No amplifier is absolutely perfect and the amplified signal will include some error components which will distort the signal to some degree. THD is either expressed in percent or dB. The amount of distortion varies between amplifier models. A smaller distortion means higher audio quality. Audiophile-grade amps will have distortion figures of at most 0.05% while consumer-grade amps have distortion of up to 10%.

Signal-to-noise ratio is another amplifier characteristic. This number describes the amount of noise which the amplified will add to the audio. The figure is expressed in dB. Audiophile-grade amps will have an SNR of 100 dB or higher. Consumer-grade amps will have at least 80 dB signal-to-noise ratio.

The majority of today's amplifiers are based on a technology called Class-D which offers higher power efficiency than amplifiers based an Class-A or Class-AB technologies. High efficiency means that little power is wasted as heat which can make the amplifier fairly small. Some of today's mini amplifiers are no larger than a deck of cards. However, when picking a Class-D (digital) amplifier, be sure that the amplifier has low distortion and a high signal-to-noise ratio.

Shopping Recommendations For Wireless Audio Kits

By Gunter Fellbaum

Eliminating the big clutter of cables has lead to a variety of wireless audio transmitter products over the years which promise to untie your home audio equipment. We will take a look at recent products to see whether they can deliver on their promise to eliminate the cable clutter and we'll examine how changing technology has impacted performance of these products.

Wireless transmission of music has started with the launch of commercial radio broadcasts several decades ago. FM radio is still popular until today although some newer technologies such as satellite radio and digital radio formats such as HD radio and DAB radio have begun to replace traditional FM radio. Today a multitude of consumer devices exist such as wireless microphones, wireless surround sound kits, Bluetooth audio transmitters, baby monitors etc which eliminate the cord by transmitting audio wireless.

Setting up speakers in another room and distributing music throughout the house are some of the applications of wireless audio. Many homes are not wired for audio. The technologies used today all have pros and cons as we will examine.

FM transmitters are using the most traditional technology in which audio is sent by changing the frequency of a radio-frequency carrier. This technology is called frequency modulation or FM. It is fairly simple to implement. Thus FM transmitters are very cost-effective. Also, FM transmission offers high range. As a result, most of today's 900 MHz wireless headphones use FM transmission. However, FM has some major drawbacks.

The FM signal will pick up static. Therefore there will be noticeable background noise. The amount of static will depend on the location of the transmitter and radio. FM radio waves are often reflected by walls and obstacles. This will cause several components to cancel each other out thus causing a varying signal quality in different locations. This phenomenon is called multipath fading. One method to cope with this problem is using two antennae instead of one. Products using this method are called diversity receivers. FM radios will easily pick up interference from other consumer devices which is another problem.

Bluetooth has gained popularity recently for wireless audio transmission even though this protocol was primarily designed to connect computer peripherals. Bluetooth audio transmitters will convert the audio signal to digital information and then transmit via the Bluetooth protocol. Bluetooth is fairly robust in terms of interference in is well standardized. Bluetooth, however, has some problems in regard to wireless audio since it was not designed for wireless audio originally. The range of the transmission is only 30 ft or less. Also, Bluetooth does not have enough space to send an uncompressed CD-quality audio signal. Therefore the audio is compressed prior to the transmission. As a result of the audio compression, the audio quality will decrease. The final problem is the fact that Bluetooth will introduce a delay in the signal (also called latency) which is a problem when used together with video since the audio will be out of sync or if used in a surround sound setup where some of the speakers would be out of sync with the hard-wired speakers.

The technologies used for satellite radio and terrestrial digital radio offer high range. However, they also use extensive audio compression. Further, a delay of up to several seconds is introduced.

Another technology which is used in wireless audio transmitters from Amphony send the audio digitally without using audio compression. The signal will retain the original quality by avoiding audio compression. The audio latency of these products is less than 1 ms and therefore this technology is also used in wireless speaker kits for home theater setups.

This technology is fairly robust against radio interference from other wireless transmitters by using a method called forward error correction. Rather than using the crowded 900 MHz and 2.4 GHz frequency bands, Amphony products operate at 5.8 GHz and thus offer high robustness. An advantage over Bluetooth is the ability to send audio to any number of wireless receivers from a single transmitter. This is important for distributing audio to multiple rooms in the home.

A glance at the hottest wireless headphone models.

By Gunter Fellbaum

Looking for a new pair of headphones and overwhelmed by the flood of models of regular and Bluetooth and cordless headphones? I will give an overview of today's models to help you pick the pair of headphones that is right for you.

Headphones are available in many different styles. In terms of design, the smallest type headphones are in-ear headphones which are plugged into the ear, some of these have a bracket that wraps around the ear. These in-ear headphones are often bundled with iPods and other MP3 players and can easily be placed in a pocket. A larger type of headphones have earpieces that sit on the ears but are still quite small. These headphones have an elastic frame that connects the two earpieces. This frame either sits on the head or wraps around the neck. These two types of headphones are typically the least expensive and you should consider them if you are on a budget. Some in-ear models are specially designed to absorb exterior noise.

If you are looking for better sound quality then you should take a look at medium-end headphones which have soft ear cushions that depending on the model will be located either on your ear or around your ear. The second design eliminates the pressure on the ears and is preferred by many people. Next you will have to decide whether you want to go with an open design where the audio can penetrate from the transducer to the outside or a closed design. Some people think that an open design will sound light and more natural. A closed design on the other hand will not allow the audio to escape and also block exterior noise.

The majority of today's headphones are dynamic which refers to the type of transducer that is used. Another type are static headphones. Static headphones are fairly expensive and require special headphone amplifiers.

Wireless headphones eliminate the headphone cord. Bluetooth headphones are another option to consider. Bluetooth headphones are a type of wireless headphones which are designed for Bluetooth-enabled devices. Such devices include cell phones. The operating range is typically only 30 ft or less. Bluetooth headphones do normally not offer audiophile sound quality.

Other wireless headphones include inexpensive 900 MHz models which use FM transmission and more advanced digital wireless headphones which work at 2.4 GHz or 5.8 GHz. In addition to noticeable hissing and distortion, FM type wireless headphones are also very susceptible to wireless interference.

Digital models such as the Amphony headphones will encode the audio into data prior to transmission which makes these models the best choice in terms of sound quality and robustness against interference. Models which use the less crowded 5.8 GHz frequency band offer the lowest amount of problems with radio-frequency interference from competing devices.

finding for finding MP3s for your iPod.

By Brian Fuller

Listeners of the free online music services AOL Radio and Yahoo! Launchcast are now building and expanding their iPods automatically by using a new recording tool called iGetMusic.

Building a free iPod music collection has traditionally been a tedious task. Ripping tracks from a CD and converting the tracks to MP3s would be the most commonly used method. Title and artist meta data would then be added manually as the final step or by using a download service.

This traditional approach has changed more recently as more and more users are downloading tracks from online retailers such as iTunes or P2P networks. Aside from P2P downloads not always being legal, downloading individual tracks takes a significant amount of time. Having to manually enter track information, searching and then downloading individual tracks for hundreds or even thousand tracks will take a large amount of time. In addition, the record industry, plagued by ever falling sales, has flooded P2P networks with fakes in an attempt to slow illegal downloads.

As an alternative, internet radio listeners have begun using various recording software such as StreamRipper to rip online radio stations and automatically build their music collection as a legal and time-saving alternative to MP3 downloads. However, the biggest problem with this method is that online radio stations are cross-fading between tracks and inserting station announcements which requires that each recorded track is missing a piece at the beginning and end. Internet radio rippers are mostly using the title information that is broadcast in order to determine the beginning and the end of individual tracks. In other words: when the title information changes, the ripper will cut the track. The problem is that online radio stations these days are deliberately varying the time when the title information changes in relation to the beginning of each track. As a result, to get decently cut tracks, users would have to manually edit each track that has been recorded and thus spend a significant amount of time.

Recently Amphony, a company that makes audio and software products has released iGetMusic which is an application that will extract music from free online radio services such as AOL Radio and Yahoo! Launchcast. The program will run in the background and save each track that is broadcast by these online radio services into a directory of choice. These songs are automatically tagged with title, artist, album and genre information which will make organizing them later on in iTunes or other music organizer software a snap. Also, this allows easy playback of songs from a particular album or artist on an iPod. All the tracks ripped by iGetMusic are full-length, i.e. don't miss anything at the beginning or end which is a big plus compared to traditional internet radio rippers.

After iGetMusic is started, a user will open up one or several browser tabs and tune each browser to the desired music channel. Since multiple browser tabs can run in parallel, the speed of growing a music collection is limited only by the speed of the internet connection and the speed of the computer. As such iGetMusic can create several thousand tracks in a day without any user input. iGetMusic checks whether the current song already exists and will not record any duplicates.

As an added bonus, iGetMusic has a feature that automatically saves the album cover of each song which is pleasing to the eye when playing back songs on a computer with a media player such as Winamp or on an iPod. A user can set up a blacklist which contains names of artists that iGetMusic should not record.

One important consideration when using iGetMusic is storage capacity of an iPod due to the large number of tracks that iGetMusic will create. An iPod nano has a memory of up to 16 GBytes and can hold up to 4000 MP3s depending on the sound quality or bit rate. Instead of MP3, iGetMusic uses the AAC Plus (M4A) format which cuts the size of the song files in half without sacrificing sound quality compared to MP3s. Therefore an iPod nano can store up to 8000 tracks generated by iGetMusic (somewhat less if album covers are stored as well). Some MP3 players do not yet have AAC Plus support. In this case iGetMusic recommends batch conversion of the tracks using a free 3rd party tool.

An overview of the newest wireless surround speaker kit products.

By Gunter Fellbaum

An increasing number of vendors has started to offer wireless speakers for home theater systems or a separate wireless surround sound kit. Multi-channel audio is still a relatively new phenomenon. As such in older homes which are not pre-wired for rear speakers, not to mention 7.1 speakers, a wireless option seems like the logical conclusion. But how reliable are these wireless surround sound kits and do they really eliminate the dreaded cable clutter?

Some wireless surround sound kits, such as the LG or Rocketfish allow to connect 2 speakers to a wireless receiver unit. This eliminates the cables from the front to the back. However, still cables need to be run from the receiver to each speaker and as such the amount of cables is just reduced but not eliminated. Another wireless surround sound product from Amphony comes with separate receivers for each speaker which in comparison to the other products does reduce the cable clutter, albeit not eliminate cables completely.

When using a wireless option, probably the most important consideration is whether or not the audio quality is affected, i.e. does the audio pick up any noise or distortion during the transmission. A good rule of thumb when picking a wireless system is to use a system where the audio is transmitted in a digital format which will avoid noise common to analog systems. Further, the amplifier inside the wireless receiver unit should be of good quality and introduce minimal distortion. Finally, the size of the wireless unit is worth considering as this unit should be hidden from view.

In a surround sound application, such as a home theater setting, the audio from each speaker naturally should be in sync with the video and also with the audio of the other speakers. Some wireless surround sound kits, such as the product from Rocketfish, will introduce a significant delay to the signal. Therefore when choosing a wireless surround sound kit, it is important to look closely at how much latency the wireless unit will introduce. The Amphony product adds a little less than 1 ms delay which should be sufficiently low for pretty much any application.

One of the main issues with wireless devices of any sort is interference from other devices. As more and more consumer devices go wireless, the available frequency space becomes more and more limited. Especially the 900 MHz and 2.4 GHz bands are exceptionally crowded, due to WiFi hot spots, cell phones with Bluetooth etc. Picking a system that avoids these frequency bands may be the logical choice, such as systems working at 5.8 GHz.

In addition to connecting rear speakers in a home theater setting, another useful application of a wireless surround sound kit is setting up speakers wirelessly in another room in cases where installing speaker wire between different rooms presents a challenge or for setting up speakers in your backyard within minutes. The applications are endless.

Make Use of Webinars to Build Your Online Income

By George J. Rodman

As technology evolves, the way we sell products on the Internet changes and this is especially true in the internet marketing niche. Until recently, majority of sales letters were chiefly made up of formatted text. Today, what we see are modern graphics packages merged with top-level copywriting. Another development is the video sales letter and with each innovative trend, it is not hard to be left behind. Yet another challenge facing internet marketers is the rising awareness of the public to all of these techniques and it has become tougher to keep prospective buyers from clicking away from what you are offering. Fortunately, there's another new sales strategy that's working very well to increase conversions these days - the "webinar", our subject here.

A vital component in becoming a soccess online is for people to trust you and to know who they are dealing with. As more people compete in the internet marketing niche, that trust has become threatened with the release of a few dubious products and the claims that come with them. However, there are still numerous ethical marketers who offer good value but they need to have a medium where they can present this. For many Internet marketers, the webinar is an important tool. In essence, a webinar is an online presentation to which you are invited by the product developers themselves or one of their representatives.

Webinars are scheduled for a certain day and time, and are live online events. The format usually takes the form of providing priceless information that demonstrates that the person presenting is knowledgeable and reliable. Sometimes there is more than one presenter, with different individuals showing their diverse areas of expertise. Once the presenter has presented his expertise and earned your trust, you can expect some kind of special offer towards the end of the webinar.

One problem with a live webinar is finding a time that fits everyone, since you could be presenting to a worldwide audience. It is possible to schedule more than once for the live webinar but today it is typical to post a recording of the webinar for people who could not attend. To see to it you still get a good attendance for the live event, you can offer something special for anyone who does make it to the live broadcast. Encouraging individuals who can't make the live presentation to watch it at a later time is new to the webinar arena. One other good aspect of recording your webinar is that it can be run and rerun whenever you want, as much as you want, with no extra work on your part. Furthermore, this overcomes any concerns you may have in presenting live or any technical hitches that can come up at a live event.

No question about it -- webinars are a priceless tool for any internet marketer, and if you take the time to understand the technology, you can look forward to more sales and conversions.

FM Modulators - Ditch The Cords

By James M. Boersma

An FM modulator is one of the best ways to enjoy listening to personal music in the car. A wireless FM modulator is a device that converts the audio from an MP3, smartphone or iPod into RF signals which are then picked up by the car's antenna and played over an unused FM station. Another product, a wired FM modulator, essentially does the same thing except it is a hardwired setup.

The problem is most people don't fully understand the differences between the two products. A lot of people would say that the hardwired setup is the best; that may not be true though.

Wireless options provide the user with less hassle, as there are no cords to mess with. In addition, they provide easy accessibility, instead of hindering the user to one vehicle.

To demonstrate the hassle of wired FM modulators let's consider the following situation. Let's say you decide to install a FM modulator in your automobile, as you want to listen to your iPod rather than commercial radio:

1. You need to pull apart the dash, and then pull out your factory radio, while being careful not to cause any damage to the current setup.

2. Once you've gotten the radio out, you will need to splice the wires making sure that everything connects properly.

3. After everything is set up, you'll need put everything back together so it looks respectable.

4. You'll have to go through the hassle of uninstalling the unit if anything breaks on the modulator or you decide to go with another product.

5. If you plan on selling or leasing a car, then installing a permanent product like a wired FM modulator is probably not the best decision.

6. The modulator will only function in one car and nowhere else.

Since most of these wired FM modulators are installed in hard to reach places, it is very inconvenient to fix or repair them if they break down.

Wireless FM modulators will allow you to avoid all of these hassles; as it is a portable wireless device that requires no tricky installation. Additionally, it provides you with the multiple options for utilization, whether in your automobile or at home.

When shopping around for a wireless FM modulator, it's important to avoid a cheap, low quality modulator. Usually you'll find an abundance of $15 or $20 modulators that look like little toys you would buy for a toddler. These will give you terrible audio quality and considerable interference. But if you know what to look for, you should be able to find a high quality FM modulator that you'll be very happy with.

A quality wireless FM modulator will also include the following benefits:

1. The modulator can be used in virtually any location and with nearly any audio source.

2. It can broadcast on any frequency between 88.1 and 107.9.

3. Volume and mute control, ability to switch from stereo to mono, automatic gain control, preset frequencies that allow you to easily switch between favorites, a microphone plug-in and a manual on/off switch.

4. A wall adapter, USB, cigarette lighter and batteries can all be used to power the device.

5. The capability to broadcast your audio up to 150 feet, just about the maximum allowed by the FCC.

Having the freedom to use the wireless FM modulator in multiple locations make it a tremendously convenient product. With audio quality that rivals a wired FM modulator, there is really no reason to limit yourself to one vehicle. A wireless FM modulator gives you many more possible uses and is a breeze to set up and maintain.

FM Modulator For My iPod

By James M. Boersma

Listening to personal music when I'm on the go is one of my favorite things in life. When I'm working out, or driving to work, it is much more enjoyable to listen to my favorite music, rather than commercial radio or silence. An iPod is so great because they can hold more music than I could have ever collected if I were buying CDs.

Portable music players have come along way since the Sony Walkman. Having the ability to walk around with our favorite music was an incredible step forward for the music industry. These days almost everyone has an mp3 player (most likely an iPod). These little devices are extremely easy to use and allow you to hold hundreds of albums in the palm of your hand. When you're in the car however, most people find that their vehicle doesn't have an easy way to hook up an iPod. Because of this, an FM modulator is a popular item for iPod owners.

Most people think that wired FM modulators are the best option. These types of modulators require extensive installation, which will cost you more time and money. The other downfall of wired modulators is that they can only be used in the car. While this is probably where you will use it the most, it is still a nice feature to be able to use it in the home as well (as with a wireless unit).

When you're shopping for FM modulators it is important to know what the important features are. If you accidentally buy a modulator that doesn't perform the way you thought it would, it can be a real bummer. Make sure you get an FM modulator that will allow you to transmit any audio source on any frequency on the public FM band. The best wireless FM modulator should also transmit your audio for up to 150 feet. This is important if you want rich, clear, static free audio.

Sites like eBay and Amazon are a good place to do product research. The feedback on these sites will usually tell you whether or not you're purchasing a quality product. Of course their is always going to be a few people who trash a product even if it's great, but as long as most of the comments are positive you can bet it is a good product.

Wireless FM modulators give you many more options than a wired unit. Being able to use the modulator in multiple vehicles and other locations like your home is a huge advantage. Wireless units are also much easier to use and setup because they require no extensive installation like a wired FM modulator. All in all a wireless FM modulator provides more bang for the buck.
