Preparation
PRESETTING THE
CONTROLS
Before you begin making connections or us-
ing your amplifier, preset the audio input
source’s and the amplifier’s controls to avoid
overdriving a channel or producing sudden
unexpected loud sounds.
Warning: To prevent possible hearing loss,
set the audio input device’s and amplifier’s
controls as indicated in the following sec-
tions. After you turn on the amplifier or
change the program source, adjust the con-
trols to a comfortable listening level.
Presetting Audio Input Devices
Always set the power control for an audio
mixer or preamplifier you connect to the am-
plifier to OFF.
Presetting the Amplifier
Set the amplifier’s controls as follows:
MOUNTING THE AMPLIFIER
You can mount the amplifier in a standard-
sized audio equipment rack or on a desk,
shelf, or table. Before you use your amplifier,
be sure you place it in a location with ade-
quate ventilation. Do not put it on thick car-
peting (which can restrict air flow) or near a
heat source such as a heat vent or radiator
(which can cause it to overheat).
To mount the amplifier on a standard-sized
audio equipment rack, drive and tightly se-
cure mounting screws (not supplied) through
the mounting holes.
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 toward the
audience (especially if the speakers are far
apart) so the 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 Speakers” on
Page 6).
