There are many lesser-known components available that are vital to
creating a high-end home theater environment. Some of these components
include sound equipment like a home theater amplifier or a surround
sound preamplifier. If you aren't familiar with these custom home
theater components, don't be overwhelmed. Below you'll find descriptions
of both as well as how you can find a home theater preamplifier and
amplifier that's right for your entertainment system.
The surround
sound preamplifier and the home theater amplifier, though similar, are
two separate components for a reason. The following is information on
these components that will help you get a better understanding of what
each does and how they work in unison.
Surround Sound Preamplifier
The
home theater preamplifier was originally a simple component contained
in the audio-visual receiver that serves as the core of a home theater
system. To allow for better control over a theatre's audio quality,
however, many manufacturers have begun offering preamplifiers as a
separate component that can be more directly controlled. This doesn't
mean that it's been completely removed from the A/V receiver and its
functions. Several models such as the NAD T175 from NAD still feature
decoding technology as well as control functions which allow for greater
customization of the audio experience.
As the name implies, the
surround sound preamplifier's job is to act as an initial amplifier for
audio signals that come in to the A/V receiver. This allows the
amplifier, or power amplifier (as it is also known), to have much less
work to do in order to get the audio level to the point that you want it
at. By using one in your system, you will also gain an additional
control point for making small adjustments to the quality of your sound
so that you can make everything exactly like you want it to.
Home Theater Amplifier
The
home theater amplifier was also originally just a component of the A/V
receiver. As the use of custom components began to rise in popularity,
though, the amplifier was one of the first pieces to be separated. A
separate amplifier allows for a much greater level of control when it
comes to the volume and clarity of your audio, and when combined with a
preamplifier, will allow you to customize your audio experience to the
layout of the room or rooms that your system covers.
As previously
mentioned, the home theater amplifier is sometimes referred to as the
power amplifier because it is independently powered, as opposed to
having to share its power with the other components of the A/V receiver.
When audio information is sent to the amplifier from an A/V receiver
or other decoder, it is sent as separate audio channels which are then
independently amplified. The specific levels of amplification can be
altered at the amplifier itself, allowing you to "shape" the end result
to accentuate the specific qualities of your audio that you prefer and
that work best with the acoustics of your home layout. Audio components
manufacturers such as PSB strive to include as many options for audio
customization as possible, ranging from basic graphics equalizers and
volume controls to virtual audio effects, bass boosting technology, and
the ability to emulate a wider range of sounds from individual speakers
to better control the way that your home theater system plays audio.
If
you are designing a very large home theater room or if you plan to have
a complicated theatre layout, consider purchasing these components.
When the two pieces are installed and are working together, you will
have greater control over volume, better sound quality and clarity, and
an optimum system for making additional customization changes to. A home
theater custom installer can give you specific information about your
amplifier needs if you are unclear about whether these items are right
for your theater.
