Then connect the power cord to a standard AC outlet. Mounting the amplifier This amplifier is designed to accept standard rack mounting installations. Two slots on each end of the front panel make it suitable for such an installation. CH 2 CH 1 Tightly secure four mounting screws (not supplied) through these fours slots and into your standard electronics equipment rack. Turn on the audio input source equipment which is connected to the amplifier INPUT jacks. MONO SIGNAL SOURCE USE CHANNEL 1 INPUT ONLY 2. [. . . ] NOTE: The extra amplifier output of 6. 35mm phone jacks can not be used for the bridged connection. It can only be used in normal (non-bridged) operation as a stereo speaker output. MONO BRIDGED OPERATION SWITCH IN "BRIDGED" POSITION DO NOT USE BLACK TERMINALS However, under excessive output conditions, the protect indicator lights remain on continuously, alerting you that the special clip circuitry has become active.
