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.

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.

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:

Control	Setting
POWER	Out
SPEAKER A/B	Out
LEFT and RIGHT	MIN
METER RANGE	Out

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).
