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).

ˆMaking Connections

Be sure you connect all auxiliary equipment and speakers before connecting and turning on power.

AUX/CD Input Jack — connect any high-level sound source (such as a tape deck, CD player, or receiver). To con- nect a stereo audio source to this jack, use a shielded Y-adapter (not supplied; available at your local RadioShack store).

PHONO Input Jack — connect a turnta- ble with a moving magnetic cartridge. To

avoid sound distortion, do not connect a high-level audio input source to this jack.

GROUND Screw — connect the ground wire (usually black or green) from your turntable to this screw to avoid a low-fre- quency hum. You can also use this screw to ground any other system con- nection.
