nections
Balanced connection - Attach as shown. Connect the (+) wire
and ground wire to terminal pins as marked.
Unbalanced connection - Attach input signal wires as shown.
Use the non-inverting (+) input and the ground terminals of the
header, and also connect a wire jumper between the inverting
(-) input and the ground terminal. The wire jumper will prevent a
reduction in gain caused by a floating unbalanced input.
Input sensitivities - - Audio signals of these levels will produce
full rated output power at 8 ohms.

barrier Strip Output Connections
Barrier strips located on the rear panel allow speaker cable
connections to the amplifier output. See the diagrams for
details on connecting speakers and/or distributed (23-, 70-,
or 100-volt) lines. Insulated connectors of the type shown are
recommended.
Always make sure the amplifier is turned off before you
change any output connections.
Loose screw terminals, insert wire connectors under screws.
Tighten screw terminals.

Bridge Mono Configuration for Direct Outputs
1.
Set into bridge mode
2. Connect the signal to channel 1's input only. Do not
connect an input signal to channel 2.
3. Use on channel 1's gain control to set the level. Both
channels' signal and clip indicators should flash identically
when the amplifier is operating.
audio Transformer Outputs
Make sure the sum of the power settings of all the speakers
does not exceed the power rating of the amplifier. It is a good
practice to allow a 20% safety margin. For example, if the
amplifier has a power rating of 300W, it is always a good idea to
make sure the sum of the loudspeaker loads on the distributed
line is 240W or less.
