Home Stereo Amplifier
A home stereo amplifier is a piece of electronic equipment that amplifies very low
power signals in the frequency range of the human ear of 20Hz to 20,000Hz to a suitable
level for pushing audio sounds through speakers. An amplifier performs tasks such
as pre-amplification, tone control and equalization. The audio could originate from
a variety of sources such as a MP3 player, TV, ipod, video game console, DVD player,
blu-ray player, CD player, radio, record deck, cassette player or microphone.
There are several parameters that an electronic design engineer will take into consideration
such as frequency response, noise, gain and distortion. It is a balance to produce
a good quality sound for the amplifier as these parameters are interdependent. For
example, increasing the gain will often lead to problems with distortion and noise.
However, negative feedback will reduce gain and reduce the distortion.
A good quality home stereo amplifier coupled with an excellent speaker configuration
will present a fantastic opportunity to enjoy your music so if you’re in the market
for a mid to high end set you should make sure that you are getting the best out of your
home stereo amplifier setup.
When choosing a home stereo amplifier make sure you match the amp correctly to the
speakers. The power output of the amp is measured in watts but make sure you look
at the RMS watts-per-channel and not total watts when comparing systems. Look for
speakers that match – or are slightly less than the watts-per-channel rating of
your amp. If the rating is too high then your amp may struggle to put enough power
through them. Conversely, too low and your speakers could be damaged by your amplifier.
Impedance matching is also important and this is measured in ohms. The impedance
rating is typically either 4 or 8 ohms so make sure that you purchase speakers that
are compatible.
You can really enhance and sound from your amp by hooking it up to a subwoofer for
a rich bass experience. This fantastic addition will give the feeling of a realistic
home theater so when comparing various amps on the market be sure to look out for
those amps that support a subwoofer. By connecting a sub woofer you will dramatically
enhance the overall experience of your home sound system and it is possible with
some amps to customize the sound so that low frequencies are driven exclusively
through the subwoofer thus feeing power to other speakers so that they produce a
rich, full sound in the mid to high frequencies.
When looking around to purchase a home stereo amplifier shop around and always purchase
the best one you can afford. Use the internet to find the best deals as it is remarkable
what deals are available at present with the current economic climate. A home stereo
amp will vastly enhance your listening pleasure as movies will almost come to life
and MP3 and CD’s will sound like they have never sounded before. Listening is believing.
