MOUNTING THE AMPLIFIER
You can mount the amplifier in a standard-
sized audio equipment rack or on a desk,
shelf, or table. Be sure you place it in a loca-
tion with adequate ventilation. Do not put it
on thick carpeting (which can restrict air flow)
or near a heat source such as a heat vent or
radiator (which can cause it to overheat).
PLACING THE SPEAKERS
Speaker placement depends on your room’s
size and arrangement. We recommend you
play a wide-range recording and experiment
with speaker placement until you find the lo-
cations that result in the best sound. For the
best results, point the speakers in toward the
listeners, especially if you place speakers far
apart so their coverage areas overlap to pre-
vent dead spots (areas not covered by the
speakers’ sound). Position the speakers
slightly above the level of the listeners’
heads (see “Connecting the Speakers” on
Page 8).

CONNECTING INPUT SOURCES
You can connect optional components such as microphones, a tuner, a turntable, or a CD play-
er to your amplifier to expand your audio system. To prevent hum and other noise, use low-ca-
pacitance shielded cable. Your local RadioShack store carries a wide selection of audio
components and cable.
Before you make any connections, be sure
POWER
on the front of the amplifier is out and the
AC power cord is not plugged in.
Connecting Microphones
You can connect up to four high- or low-impedance microphones to the microphone inputs on
the back of the amplifier. Each input (labeled
MIC 1
,
MIC 2
,
MIC 3
, and
MIC 4
) has a balanced
and unbalanced jack. You need a microphone cord with a

-inch (6.35-mm) plug to connect to
an unbalanced jack or a microphone cord with a 3-pin XLR plug to connect to a balanced jack.
