The Basics - B&K PT5 Owner's Manual

THE BASICS

The following is intended to familiarize users with common terms and applications of home audio equipment.
Amplifier - An amplifier takes the output of a preamplifier and increases its level to that necessary to drive a
speaker. Your preamplifier Tuner includes full-range, high-pass, low-pass and mono preamplifier outputs for
connecting to external amplifiers and/or powered speakers.
Preamplifier - A preamplifier typically includes the capability to select from a number of sources, adjust volume
levels and route the signal to an amplifier. Optionally the preamplifier may include the capability to process the
audio signal to adjust for room and listening taste preferences. Your Preamplifier Tuner is capable of adding or
subtracting bass and treble to correct for any needed room equalization. A loudness circuit may be used to further
shape the audio signal for increased clarity and intelligibility at low levels.
Sources - Your Preamplifier Tuner can directly provide audio from its built-in AM/FM tuner. Typically you will want
to connect a number of additional sources (CD, DVD player, etc.) to your Preamplifier Tuner. Your Preamplifier
Tuner is designed to accommodate a wide range of audio sources.
Speakers and Bass Management - An audio system typically uses 2 speakers located front left and right.
Additionally, a sub woofer may be used with good results anywhere in the room. Small speakers usually require a
crossover to remove low frequency (bass) audio and pass this on to a sub woofer. You Preamplifier Tuner
includes an electronic crossover that adds the capability to work with large speakers (full range), or small
speakers (high-pass) and a sub woofer (low-pass). Excellent results can also be achieved using large speakers
and a sub woofer.
Zone - A zone is usually a room with speakers installed in it. Using Code Sets, your Preamplifier Tuner may be
configured for use in systems of up to 16 zones.
