SYSTEM CONFIGURATION - BRIDGED MODE

Bridged Mode
In this mode both the left and right channels are combined for a higher power
mono output. For proper operation, the Master Level left and right channel
adjustment on the back panel should be set to the center position to start and
then adjusted appropriately from there.
1. Unplug the amplifier.
2. Set the Stereo/Bridge switch to Bridge Mono.
3. Connect the line out from a preamplifier or source to the Left and Right
econdary input jacks of the amplifier. The P125 will sum the two channels
into a mono signal.
4. Connect the negative lead (-) of the speaker cable to the R(+) terminal.
Connect the positive lead (+) of the speaker cable to the L(+) terminal. (See
the markings above the terminals on the rear panel). An 8 Ohm minimum
load is recommended.
5. Restore power to the amplifier.
6. Be sure to equally adjust the Master Level right and left.
7. Set the Balance control on the front panel to Center.
