ˆConnections

CONNECTING AN INPUT SOURCE

You can connect a component such as an audio mixer or preamplifier to the inputs on the back of your amplifier. Each input (la- beled INPUT and INPUT MONO) has a bal- anced and unbalanced jack. You need a shielded cable with a 1/4-inch (6.35-mm) phono plug to connect to an unbalanced jack or a cable with a phono-type plug to connect to a balanced jack. To prevent hum and oth- er noise, use low-capacitance shielded ca- ble. Your local RadioShack store carries a wide selection of audio components, parts, and cables.

Note: If you are using the MIC level inputs, you must connect an audio mixer or pre-am- plifier to this amplifier.

is off and the AC power cord is not plugged in.

Unbridged Connection

If you are connecting more than one speaker on the same channel (unbridged connec- tion), connect your audio mixer’s or preampli- fier’s left and right output jacks to the INPUT R and INPUT L jacks on the back of the ampli- fier. Then, make sure STEREO/MONO on the back of the amplifier is set to STEREO.

Cautions:

•You can connect audio mixers or pream- plifiers to either the balanced or unbal- anced jacks. Do not connect input sources to both jacks at the same time.

•Before you make any connections, be sure POWER on the front of the amplifier

Bridged Connection

If you are connecting high-power speakers that can handle a power output of 350 watts (bridged connection), connect your audio mixer’s or preamplifier’s output jack to the IN- PUT MONO or INPUT L jack on the back of the
