A Few Pointers About The Noise Performance Of Today's Audio Amplifiers

By Gunter Fellbaum

To help you decide on a stereo amplifier model, I will describe the expression "signal-to-noise ratio" which is usually utilized in order to describe the performance of audio amps.

When looking for an amp, you initially are going to check the price, wattage amongst additional fundamental criteria. Nonetheless, after this initial selection, you will still have quite a few models to choose from. Now you are going to focus more on some of the technical specifications, including signal-to-noise ratio and harmonic distortion. Each amplifier is going to create a certain level of hiss and hum. The signal-to-noise ratio will help quantify the amount of static generated by the amp.

Evaluating the noise level of different amps may be accomplished fairly easily. Simply gather a few types that you wish to compare and short circuit the inputs. Next put the amp gain to maximum and verify the amount of static by listening to the speaker. Usually you will hear two components. The first is hissing. In addition, you will regularly hear a hum at 50 or 60 Hz. Both of these are components which are generated by the amplifier itself. Then compare different amplifiers according to the following rule: the lower the level of noise, the higher the noise performance of the amplifier. Yet, bear in mind that you must set all amplifiers to amplify by the same amount to evaluate different amps.

If you favor an amplifier with a small amount of hissing, you can look at the signal-to-noise ratio figure of the data sheet. A lot of makers will display this figure. amplifiers with a large signal-to-noise ratio will output a low amount of hiss. One of the reasons why amps create noise is the fact that they utilize components like transistors and resistors that by nature generate noise. The overall noise is dependent on how much hiss every element creates. Yet, the position of those elements is also essential. Components that are part of the amp input stage are going to generally contribute most of the noise.

Most of recent amplifiers are based on a digital switching architecture. They are known as "class-D" or "class-T" amps. Switching amps include a power stage which is always switched at a frequency of around 400 kHz. This switching noise may cause some level of loudspeaker distortion but is typically not included in the the signal-to-noise ratio which only considers noise between 20 Hz and 20 kHz.

The signal-to-noise ratio is measured by inputting a 1 kHz test tone 60 dB underneath the full scale and measuring the noise floor of the amplifier. The gain of the amplifier is set such that the full output wattage of the amplifier can be realized. After that, only the noise in the range of 20 Hz and 20 kHz is considered. The noise at other frequencies is removed via a filter. Then the level of the noise energy in relation to the full-scale output power is calculated and expressed in decibel.

Often you will find the term "dBA" or "a-weighted" in your amplifier parameter sheet. A weighting is a method of showing the noise floor in a more subjective fashion. In other words, this method tries to express how the noise is perceived by a human being. Human hearing is most sensitive to signals around 1 kHz while signals under 50 Hz and higher than 14 kHz are barely noticed. The A-weighted signal-to-noise ratio is usually higher than the unweighted ratio and is shown in a lot of amplifier spec sheets.

Manchester United News: Sir Alex Ferguson Snaps

By Nichol Potts

On the night that both Manchester sides tie at 1-1 in the Champions league, United manager gets bothered by goalkeeper's question.

On Wednesday, September 14, Aleksandar Kolarov curls his free kick over the wall in Napoli which provided Manchester City a point in their Champions League debut.

Sir Alex Ferguson's problem about which goalkeeper was his No. 1 was unmasked last Wednesday when he told a Television reporter something about her trying to find little things that were stupid by inquiring if David de Gea could be dropped from the match on Sunday against Chelsea.

The Danish goalkeeper, Anders Lindegaard, who believes that he has a call on being the first selection, scored two fine late saves to maintain a 1-1 draw for Manchester United's Champions League at Benfica. The problem caused Ferguson to lose his temper with the ITV presenter Kelly Cates, who is the daughter of Liverpool's manager Kenny Dalglish. Ferguson reportedly stated something to the effect that it was his understanding that we had before that game that on Sunday David de Gea will be playing. Ferguson also stated to Cates that he didn't understand why he asked these questions.

Lindegaard stated that he wants to be No.1 on a night when both Manchester City and United were rescued to a 1-1 draw after falling behind. The rescue came to Manchester City by a 74th minute goal by Aleksandar Kolarov goal in a brilliants Champions League debut at home in Napoli. When he was asked about challenging for the first spot on the team spot, he responded something to the effect that he wasn't here to pick his nose.

Ferguson later restated his faith in De Gea stating that he was quite impressed with Anders, but that, actually, they have two great goalkeepers in David and Anders. He also stated that they were consistently getting to the point when they were going to share that. On Tuesday, Anders will possibly play against Leeds United and on Sunday, David will play against Chelsea. There are many chances to spread that load, since coming over to the English game, it's such an intensely competitive league for a young goalkeeper. There will be a time when he will have to give him a break.

At Bolton, last Saturday, Lindegaard wasn't chosen for United's win in spite of the fact that Ferguson was apparently giving some serious consideration to protecting De Gea from the aerial threat that punished him on the opening weekend of the season at West Bromwich Albion. Lindegaard reportedly stated about facing Benfica that it was great fun and very amusing and that's the most important reason that you play football, for the fun of it. He also reportedly stated something to the effect of the fact that if there aren't some nerves involved then it's not that much fun because it's what makes him feel alive and that he was satisfied with his performance but that it was somewhat sad that he failed to save the first goal.

Should You Build Your Own Greenhouse?

By Eric Huff

So why do you want to construct a greenhouse? There are actually many reasons that you should want to have a greenhouse, and also build it yourself. The very first reason is to grow plants to use during the cold months.The number one rationale is to be able to have living plants over the cold part of the year. To begin with, it is much easier to raise small vegetables as opposed to larger ones. A green house is a good way to start tender plant seedlings, since you will have better success by protecting them inside a warm spot. The great thing about having a greenhouse stands out as the experimenting you can do. It's really a wonderful hobby working with different plants, and developing new varieties.

As soon as you decide you intend to to have a greenhouse, you have to take a look at how to select the best location. You have to locate it where it can receive a lot of sunlight. Even though continual daily sunlight is the top option, plants typically need morning sun the most. There are actually two reasons why you should face the long side of your garden greenhouselengthier side of your greenhouse must face the south for two reasonsThere are two reasons why you need to construct your greenhouse with the longer side facing to the south.First would be to have the direction of the roof designed to catch the rays of the sun in the greatest amount. Another reason is that often when you use a shade cloth you are only required to shade a single side and not both. To safeguard your greenhouse from daytime sun, you can protect it with maple or oak trees. Nevertheless, just remember that your greenhouse requires morning sun and so cannot be shaded by these trees in the morning..

It is crucial that you have a reliable water origin regarding your greenhouse. It is possible to manage this step with a hose that elongates the full length of the greenhouse or you can install a completely separate water system. In addition to the water source, you additionally need a drainage process. Constructing a greenhouse on higher ground will make it possible for any water used for irrigation to quickly drain away.

In terms of structuring your greenhouse's visual appearance, you have several choices. One uncomplicated option is to construct a lean-to greenhouse on the side wall structure of your house or garage. This is an inexpensive way to go given that you're using an existing structure, but don't forget to face the wall so that your plants will get all the sunlight they need. Another one that is also low-cost is the Quonset hut. They are domed shaped, being described as hoop style, and they are easy to heat. Another style is the Gothic Arch greenhouse which is similar to the Quonset style, but the curved roof is pointed top, and the sides are generally straighter.

After that, there is the Classic A-Frame, which come with high, slanted sides, which causes them to be trickier to heat. A Modified A-Frame might be the thing you need if you want the Classic A-Frame without having the steep roof. A Barn-Style greenhouse offers a great deal of space and has a resemblance to a barn in appearance. With an even-span greenhouse, you can connect a complete building to one end of an existing building.

Recommendations For Installing Your Audio System

By Gunter Fellbaum

If you just bought a home theater system or a set of wireless speakers, you may need some tips on properly setting it up if you don't want to hire an installer. You may think you are technically savvy and that installing your new home theater system will be a snap. I will give some recommendations that will help you avoid some commonly made mistakes.

The following components are usually included in your home theater system: 5 to 7 satellite speakers, subwoofer and a central component. This central component is the central hub of your home theater system. You will typically be able to control it by remote control. It will process the sound and split into the sound component for each separate speaker.

Choose a location for the surround receiver. You might want to put it where you have the most amount of space. However, please also keep in mind that you will need to run speaker wire to each speaker, so don't pick a location that is too remote. If you have your TV up center then a good spot for your receiver might be somewhere near your TV. This will also simplify hooking up your receiver to the audio output of your TV. However, pick an alternate place if your TV already is fairly crowded with other equipment.

Connecting the receiver to power and to your TV or DVD is fairly straightforward. Most modern TVs have an optical output which connects directly to your receiver via a fiberoptical cable. This cable may not be included with your system but it is available at any electronics store. However, setting up your speakers may be a bit more tricky.

If you have wireless rear speakers you will not need as much speaker cable and the setup will be somewhat easier. First of all, measure how much speaker cable you will need. Make sure to add some extra cable to take into account those bends and corners. Pick the gauge of the speaker cable depending on how much power you intend to drive your speakers with. The higher the power the thicker the speaker cable. Your subwoofer will usually have a built-in amp and connect to your receiver via RCA cable.

The satellite speakers each connect via a speaker terminal which is usually color coded to help ensure proper polarity. Most speaker cable will show one strand in a different color. This is essential since it will help ensure the correct polarity of the speaker terminal connection. Simply attach the different-color strand to the speaker terminal which is colored. Similarly, each speaker output of your surround receiver is color coded. When attaching the cable to your receiver, observe the right polarity once again. This will keep all of your speakers in phase.

Wireless rear speakers will typically incur an audio delay during transmission. This delay is also called latency. Typically the latency ranges between 1 and 20 ms. For optimum effect, it is best if all of the speakers are in sync. If you have a system that uses wireless rears and wired front speakers, i.e. you have a mix of wireless and wired speakers, you should try to delay the audio going to the wired speakers by the latency of the wireless speakers.

Check the user manual to find out how to set a delay on specific channels. Usually home theater systems that were designed for wireless speakers or come with a wireless transmitter will have this capability and allow your speakers to be in phase.

An Quick Guide Of The Audio Distortion Term Of Cordless Speakers

By Gunter Fellbaum

In this article, I will explain the term "total harmonic distortion", often also called "THD" which is frequently used to describe the performance of wireless outdoor speakers.

Looking for the perfect model from the huge amount of products, you may have a hard time understanding some of the technical language and terms that you will find in the specifications of today's wireless speakers. THD is usually not as easily understood as some other commonly used terms such as "signal-to-noise ratio" or "frequency response".

In a nutshell, THD shows the difference between the sound that is produced by the speaker versus the audio signal with which the speaker is driven. The most common ways to express distortion are percent and decibel. These two conventions can be translated into one another. The percentage shown as THD describes which amount of energy that is radiated by the speaker are higher harmonics versus the original signal. 10% would mean that one tenth is distortion. 1% would mean one hundredth etc. 10% equals -20 dB while 1% equals -40 dB.

Harmonic distortion inside a wireless speaker is actually the result of several components, including the power amplifier which is built into the speaker to drive the speaker element. Amplifier distortion usually depends on the amplifier output power and is sometimes specified for several power levels.

Harmonic distortion measurements are usually made by feeding a test tone into the speaker. This tone is a pure sine wave signal with minimum distortion. The frequency of this test tone is usually 1 kHz. Distortion, however, is usually dependent on the signal frequency. Most amplifiers will show increasing distortion with increasing frequency. In particular digital class-D amplifiers will have fairly high distortion at frequencies above 5 kHz.

Another element causing distortion is the speaker element which typically works with a diaphragm that carries a coil which is suspended in a magnetic field. The coil is moving in accordance to the change in the magnetic field which is excited by the audio signal but does not correspond 100% with the signal due to core losses and other factors. As such the result is distortion caused by the speaker element. Many manufacturers will specify harmonic distortion depending on the power level because usually the higher the speaker is driven the higher the amount of distortion.

As such both the amplifier as well as the speaker element itself contribute to distortion. In addition, there are other factors which also contribute to distortion. The total amount of distortion is the sum of all of these factors. Depending on the material used to build the speaker enclosure, there will be vibrations or box resonances. These usually depend on the sound pressure level, the box shape, the enclosure material and audio frequency. Therefore additional sound distortion will be caused by the box itself.

The overall distortion of the speaker is usually determined by a measurement which includes a low-distortion audio generator and a microphone which is connected to an audio analyzer. The audio analyzer will determine the amount of higher harmonics and compare these with the main signal to compute the distortion. However, pure sine signals hardly give an accurate picture of the distortion of the wireless speaker with real-world signals. A better distortion analysis is the so-called intermodulation distortion analysis where a test tone which consists of several sine waves is used. Then the number of harmonics at other frequencies is measured.

Also, please note that many wireless speakers will experience signal distortion during the audio transmission itself. This is mostly the case for transmitters that use analog or FM type transmission. Better models will use digital transmission and transmit at 2.4 GHz or 5.8 GHz to minimize signal distortion.

A Brief Overview Of Power Amplifiers

By Gunter Fellbaum

None of today's audio systems would be possible without the help of modern audio amplifiers which strive to satisfy higher and higher demands regarding power and audio fidelity. There is a large amount of amplifier designs and models. All of these differ in terms of performance. I will explain some of the most common amplifier terms such as "class-A", "class-D" and "t amps" to help you figure out which of these amps is best for your application. Also, after reading this article you should be able to understand the amplifier specs which manufacturers publish.

The basic operating principle of an audio amp is fairly straightforward. An audio amp will take a low-level audio signal. This signal usually comes from a source with a fairly high impedance. It then converts this signal into a large-level signal. This large-level signal can also drive speakers with low impedance. The type of element used to amplify the signal depends on which amplifier architecture is used. Some amps even use several types of elements. Typically the following parts are used: tubes, bipolar transistors and FETs.

Tube amplifiers used to be common a few decades ago. A tube is able to control the current flow according to a control voltage which is connected to the tube. Unfortunately, tube amplifiers have a fairly high amount of distortion. Technically speaking, tube amplifiers will introduce higher harmonics into the signal. However, this characteristic of tube amps still makes these popular. Many people describe tube amps as having a warm sound versus the cold sound of solid state amps.

Also, tube amps have fairly low power efficiency and thus radiate a lot of power as heat. Yet another drawback is the high price tag of tubes. This has put tube amps out of the ballpark for many consumer devices. As a result, the majority of audio products nowadays uses solid state amps. I will explain solid state amps in the following paragraphs.

The first generation models of solid state amps are known as "Class-A" amps. Solid-state amps use a semiconductor rather than a tube to amplify the signal. Usually bipolar transistors or FETs are being used. In a class-A amp, the signal is being amplified by a transistor which is controlled by the low-level audio signal. In terms of harmonic distortion, class-A amps rank highest amongst all types of audio amps. These amps also usually exhibit very low noise. As such class-A amps are ideal for very demanding applications in which low distortion and low noise a crucial. Class-A amps, however, waste most of the energy as heat. Therefore they usually have large heat sinks and are fairly heavy.

By using a series of transistors, class-AB amps improve on the low power efficiency of class-A amps. The operating working area is divided in two separate areas. These two areas are handled by separate transistors. Each of these transistors works more efficiently than the single transistor in a class-A amp. The higher efficiency of class-AB amps also has two other advantages. Firstly, the required amount of heat sinking is reduced. Therefore class-AB amps can be made lighter and smaller. For that reason, class-AB amps can be made cheaper than class-A amps. Class-AB amps have a drawback though. Every time the amplified signals transitions from one region to the other, there will be some distortion generated. In other words the transition between these two areas is non-linear in nature. Therefore class-AB amps lack audio fidelity compared with class-A amps.

Class-D amps are able to achieve power efficiencies above 90% by using a switching transistor which is constantly being switched on and off and thus the transistor itself does not dissipate any heat. The switching transistor, which is being controlled by a pulse-width modulator generates a high-frequency switching component which has to be removed from the amplified signal by using a lowpass filter. Both the pulse-width modulator and the transistor have non-linearities which result in class-D amps having larger audio distortion than other types of amplifiers.

More recent audio amps incorporate some sort of mechanism to minimize distortion. One approach is to feed back the amplified audio signal to the input of the amp to compare with the amplified signal. The difference signal is then used to correct the switching stage and compensate for the nonlinearity. "Class-T" amps (also called "t-amp") use this type of feedback mechanism and therefore can be made extremely small while achieving low audio distortion.

Radio - Still A Crucial Method Of Communication In The 21st. Century

By Owen Jones

Radio is one of the most remarkable inventions of the Nineteenth Century. Although it was thought of in 1879 by Marconi, the everyday, wide scale broadcasting of radio began later in the 1920?s. Radio is indubitably one of the mothers of innovation because it paved ways for further inventions in the field of communication.

It transmits its signals in free space through electromagnetic waves. The word ?Radio? stands for wireless. Though new technological innovations have left it well behind, its importance as a method of communication cannot be underestimated. Radio is thought to be the mother of all the other inventions in the province of communication.

TV and the Web have left radio a long way behind in the race for communicational improvement. In spite of the fact that contemporary means of communication are used a lot more these days, none of the contemporary means of communication has replaced it.

In the starting of the Twentieth century, radio was in essence used to pass orders and important knowledge during war or emergencies. Later on, it was used to broadcast all kinds of programs too.

Radio has successfully served as an important way of transmitting programs ranging from news to drama, music, comedy and arts etc.

Radio offers access to limitless knowledge from around the world. Listening to a radio is much easier and less time consuming than watching TV or using any other form of communication. We do not have to put other items on hold whilst listening to a radio.

Radio can be listened to whilst driving, hiking or even lying on the bed with one?s eyes closed. It is one of the biggest benefits associated with listening to a radio. There is no harm in listening to a radio while driving because it does not distract your attention to a detrimental extent.

Radio is a cheaper way of serving adverts for businesses trying to market and sell their products or services. Clive Anderson writes in favour of radio and claims that the pictures suggested by radio are better than any other mode of communication. These pictures are not real pictures. He means the emotional touch.

Radio offers more emotional involvement. Radio transmissions on a home scale. Normally one or two hosts talk to their audience in such a manner that the program appears to be specially tailored to each listener.

Radio programs are categorized on grounds of the taste of the audience and so a huge variety of programs are transmitted to cater for a colossal populace. The audience feels an emotional connection with the program makers.

Radio not merely saves time and money but also physical energy. Less attention is required to grasp audio knowledge than visual. Television, mobile, Wi-Fi, satellite navigation systems and Radar etc. are all the product of radio technology one in manner or another.

This old invention and its principles are still in use and their importance can?t be denied even in the modern era of technological advancement and innovation. Although just sound is produced by radio, it has a colossal effect on the thinking of individuals because it has a huge reach and people listen to it.
