PRESETTING THE
CONTROLS
Warning:
A sudden high output from the
amplifier could damage your hearing or
the speakers connected to the amplifi-
er’s output.
To avoid accidentally overdriving a
channel or prematurely amplifying an
audio input, set all the amplifier’s front-
panel controls to their lowest settings.
To avoid sudden audio from the input
sources, be sure all audio devices are
turned off before you connect them to
the amplifier.
CHOOSING A LOCATION
Choose a location with adequate venti-
lation. Do not place the amplifier on thick
carpeting or cushions (which can restrict
the air flow) or near a heat source, such
as a heat vent or radiator (which can
cause the amplifier to overheat).
PLACING THE SPEAKERS
Speaker placement depends on your
room’s size and arrangement. We rec-
ommend you play a wide-range record-
ing and experiment with speaker
placement until you find the locations
that result in the best sound.
Notes:
Place the speakers so they are
mounted slightly above the listeners’
heads and pointed toward them.
When using more than one speaker,
overlap the projection areas of the
speakers to prevent “dead” spots.
