Tips For Finding The Best Audio Amplifier

By Brian Fuller

I will take a look at some audio amplifiers as well as mini amplifier models and explain some basic terms to help you pick the ideal amplifier for your speakers

Audio amplifiers come in all different shapes and sizes. They use different technologies and have many technical specs. This makes it difficult to decide which model to pick. You don't have to be an expert. Just follow some simple guidelines and you should be satisfied with your amp.

Amplifiers differ in their size and range from models that will take up a good part of your living room while some of the latest mini amplifier models are as small as a deck of cards. Many amplifiers are rack sized. This allows them to be stacked on top of your other audio equipment.

Most of today's audio amplifiers are based on solid-state technology while a small portion is based on tube technology which has been popular over a decade ago. Unfortunately, tube amplifiers have fairly high audio distortion which describes how much the audio signal is degraded by the amplifier.

Harmonic distortion of tube amplifiers is often as high as 10%. Solid-state amps will have lower audio distortion. However, distortion will depend on the particular audio amplifier technology. Some of the most popular technologies in the past have been "Class-A" and "Class-AB" technologies. These technologies use different arrangements to amplify the audio. Amplifiers based on any of these technologies are also called "analog amplifiers". Audio amplifiers which are based on these technologies typically have low harmonic distortion. Also, this technology is fairly inexpensive. However, the drawback is that the power efficiency is only in the order of 20% to 30%. Power efficiency describes how much of the electrical power is used to amplify the audio as opposed to being wasted as heat. Amplifiers with low power efficiency will require fairly large heat sinks because most of the power is radiated.

In contrast, "Class-D" amplifiers which are also called "digital amplifiers" offer a power efficiency of typically 80 to 90%. This allows the amplifier and power supply to be made much smaller than analog amplifiers. The tradeoff is that digital amplifiers often have higher audio distortion than analog amplifiers. This is mostly a result of the switching distortion of the output power stage. Most recent digital audio amplifiers, however, employ a feedback mechanism and can minimize the audio distortion to below 0.05%.

The amplifier should be able to deliver enough output power to sufficiently drive your speakers which will depend not only on how much power your speakers can handle but also on the size of your listening environment. Speaker power handling is given as peak power which describes the maximum amount of power during short bursts while average power refers to how much power the speakers can handle continuously.

If your listening environment is fairly small then you may not need to drive your speaker to its rated power handling value. You would probably be good having an amplifier that can deliver 20 to 50 Watts even though your speakers may be able to handle 100 Watts of power. Note though that speakers differ in their sensitivity. Typically a low-impedance speaker will be easier to drive to high volume than a high-impedance speaker. Be sure that your amp can drive your speaker impedance. You can easily find the rated speaker impedance range in your amplifier's user manual.

Two other important parameters to look at when picking an amplifier are signal-to-noise ratio and frequency response. Signal-to-noise ratio describes how much noise the amplifier will introduce and should be at least 100 dB for a high-quality amplifier. The frequency response shows which audio frequency range the amplifier covers and should be at least 20 Hz to 20 kHz.

A Glimpse At A Few Of The Hottest Wireless Devices

By Brian Fuller

Lately a large number of wireless audio products have emerged such as latest-generation wireless headphones, iPods, cell phones and wireless amplifier products which promise to cut the cord. I will take a look at some of the newest gadgets and technologies to find out how well they work and in which situations they work best.

Some products come with wireless already built in while others, in particular streaming audio products, often have optional wireless capability. Newest touch-screen iPods and iPhones already have WiFi and Bluetooth built in.

Bluetooth is a fairly low-cost solution but has some drawbacks which are often overlooked.

1) Limited range

Bluetooth devices typically only have a 30-foot range which limits Bluetooth to single-room applications.

2) Audio compression due to limited data rate

Bluetooth will apply audio compression since it does not reliably offer a high-enough data rate for uncompressed audio. Audio compression will degrade the audio quality to some extent. High-quality audio transmission typically does not tolerate this type of degradation. Therefore Bluetooth is normally not used in high-end audio products.

3) Audio latency

Due to audio compression, Bluetooth will introduce a signal delay of at least 10 ms which will cause the audio to be slightly out of sync in case of video and real-time applications. This is again less of a problem for MP3 players.

4) No multiple headphone support

Bluetooth does not support any number of headphones which may be a problem if you have a larger number of people who want to listen to headphones from a single transmitter device.

Another common protocol is WiFi which supports uncompressed audio but also has problems simultaneously streaming to multiple receivers. It is convenient for streaming music from a PC due to the high availability but is normally not used in wireless headphone products due to the relatively high power consumption of WiFi.

Wireless speakers and wireless amplifier products for home theater speakers typically use their own proprietary protocol. Entry-level wireless headphones and speakers typically still use FM transmission which offers low cost but is prone to noise and audio distortion.

More advanced wireless protocols are based on digital formats which eliminate audio degradation and incorporate advanced features such as error correction to cope with interference from competing wireless devices.

Advanced wireless amplifier devices support uncompressed digital audio streaming to preserve the original audio quality. Some of these protocols allow streaming to an unlimited number of wireless amplifiers which is convenient for whole-house audio distribution. The audio latency ranges from below 1 ms to up to 20 ms. A small latency is important for wireless surround sound applications. These wireless audio transmitters typically work at 2.4 GHz. There are also some products such as Amphony's line of wireless audio products which work at 5.8 GHz. Products that operate at 5.8 GHz have less competition from other wireless devices than those using the crowded 2.4 GHz frequency band.

Wireless amplifiers offer different levels of audio quality, output power and standby power. Wireless Class-D amplifiers normally have standby power of 5 Watts or less and a power efficiency of greater than 80% but sometimes high audio distortion. Picking a low-distortion amplifier is key. Good-quality wireless amplifiers have audio distortion of less than 0.05%.

AOL Radio - The Extinction Of Traditional Stations?

By Brian Fuller

AOL Radio, Pandora, Slacker and Last.fm are some of the online radio services which have become popular these last few years. Many of these are also available on mobile devices such as cell phones. I will look at the impact of online radio on traditional radio broadcasters to find out if this means the end of local radio stations.

Local radio seems to be having a hard time in today's radio landscape with competing satellite and online radio services taking away listeners by offering commercial-free music and entertainment. There is virtually an unlimited number of online radio stations available.

While traditionally local radio has been the only truly mobile radio, online radio services such as Pandora are now available on wireless audio transmitter and portable devices such as cell phones.

AOL Radio which boasts 200 plus music channels of 25 genres uses CBS radio as its underlying platform. It also offers access to 150 national CBS radio stations. The underlying platform "play.it" also has a feature that allows listeners to create their own radio stations by entering preferred albums, artists etc. The individual tracks of each music channel are also available for storage on an iPod through 3rd-party software such as iGetMusic.

Users can also create customized radio on other online music services by entering the artist and album names and these services will play songs based on that information. Other services, however, fail to offer fully customized music channels.

Does online radio mean the end of local radio? The growing number of options clearly is going to shrink the market share of traditional radio broadcasters. Online radio is particular useful for niche broadcasters who have been unable to broadcast due to the high cost and licensing of frequency space.

The large number of available stations is a big plus for online radio listeners. However, this is a problem for online broadcasters. This large number of stations is diluting the number of listeners. Therefore streaming radio broadcasters have found it difficult to be profitable. However, online radio has less pressure to insert commercials which has made the content more appealing to listeners.

However, local radio has one big advantage over satellite and online radio. That is local content such as local news and events. One drawback of local radio has been the poor audio quality of FM broadcasts. However, that is being remedied by the recent introduction of digital radio broadcasts such as HD radio. It is hard to predict a clear winner in the battle between online and local radio since both offer their own unique content and offer high mobility which are the key factors that will determine the fate of each services.

XM vs. Sirius Satellite Radio Debate: Which Will Be Your Choice?

By Matt Barns

We have all heard of the two major satellite companies available today, Sirius Radio and XM Satellite Radio. Many people, maybe even you, don't even know that much about them such as costs or what is even available on a satellite radio. They are tired of listening to the old AM and FM standard radio stations for valid reasons. Many FM and AM radio stations publish long waits with commercials. Whichever reason it may so be, people are turning to satellite radio more and more than regular radio stations.

Both companies are able to offer you static free radio due to satellites. XM (based in Washington D. C. ) has two and Sirius (based in New York) has three satellites across the United States. Both companies offer users commercial free radio. Sirius offers over 125 channels and XM offers 160 different channels. There are dedicated channels for genres of music such as jazz, folk, country and pop for die-hard fans. One cool feature of satellite radio is you can see the name of the artist playing as well as the song title. So never again do you have to spend time wondering just who sang that song you just heard! There are also channels for local weather and traffic, sports, comedy, women's issues, talk shows, even old time radio shows. Soon, you may be able to see video as well as hear audio on your satellite radios.

There are also celebrity shows for both satellite radio companies. Martha Stewart recently signed a deal to launch a 24-hour radio channel on Sirius Satellite Radio. And most everyone has heard that Howard Stern is on Sirius as well - uncensored. Having gotten in trouble with the Federal Communications Commission (FCC) for his radio talk show, he decided to jump to the uncensored airways of satellite radio. Since his show started, the Sirius subscriber base has increased by at least 2. 7 million. If have satellite radio and want to hear National Public Radio (NPR), you will have to subscribe to Sirius as they are the only one offering NPR. But XM is not to be left behind by Sirius. XM signed Snoop Doggy Dog, but the big coop is Oprah. In September of 2006, XM users will be able to tune in to Oprah & Friends. The new channel will offer broadcasts of The Oprah Winfrey Show, O, the Oprah Magazine and programming on fitness, health and self improvement.

It is all simply amazing, but wait, what do you honestly have to have to receive satellite radio? You need to have either a Sirius or an XM radio. It doesen't have to be a radio for use in your car either. Radios for home are available today and there are radios you can use either at home or in your car. A basic setup price by XM and Sirius is as low as $49. 99. You will need to subscribe to a service though, indeed. Both companies charge $12.95 a month for you to receive satellite signals on your radio. You may save, however, if your using multiple cars by purchasing a family plan available from either company.

How popular is satellite radio becoming lately? In March 2005, Hyundai announced that it will be the first car manufacturer will be in all of its models sold in the U.S. satellite radio. Every modern, including the famous Sonata, Santa Fe and Elantra models will be equipped with XM satellite radio. When it was announced, the parent company XM's stock increased by more than 8 per cent. Jaguar and Mercedes-Benz also announced in March 2005 Sirius radios will be their model for some distributors choose to install.

So which satellite radio should I choose, you ask? It depends on you. You should check out the stations available by visiting the company website before any decision is made. Both of them are offering the radio at comparable prices, so it really comes down what you want to hear. Are you a fan of Stern? Then you have to go with Sirius. But if you love Oprah, you can listen to her on Oprah XM. Regardless of which one to choose, you will definitely be very pleased with either of the services and/or satellite receptions.
