Bridged Mono Input ConnectionThe following diagrams show input and output
connections for bridged mono mode. Note that the MPC200 and 200T models use a different
method for bridged mono than do the MPC300, 300T, 600 & 600T.
MPC200 & 200T Bridged Mono Configuration
1) To engage the bridged mono mode, jumper the barrier strip inputs on the rear, in accor-
dance with the diagram printed under the barrier strip inputs.
2) Connect the amplifier input to channel 1 only with the jumpers as shown to channel 2.
Channel 1 and channel 2 gain control settings must be set the same!
MPC300, 300T, 600 & 600T Bridged Mono Configuration
1) Set the mode switch on the back panel to the bridge position.
2) Connect the signal to channel 1s input only. Do not connect an input signal to channel 2.
3) Use only channel 1s gain control to set the level. Both channels SIGNAL and CLIP
indicators should flash identically when the amplifier is operating.
Bridged Mono Speaker Connection
Low impedanceA speaker load of 4 ohms or higher can be connected across the two + low
impedance terminals of the two channels. The positive speaker wire goes to channel 1s +
terminal and the negative wire to channel 2s + terminal.
Audio transformerFor bridged mono operation using the AUDIO TRANSFORMER outputs,
a jumper wire must be connected between the AUDIO TRANSFORMER 0V terminals of
the two channels. See hookup diagrams.
When operating the amplifier in bridged mono mode, neither of the speaker
wires is at ground potential. Grounding either of the speaker wires can short out
one side of the power amplifier. Use the same precautions in handling and
dressing the wire as you would for the normal “hot” outputs. Ensure that neither
wire connects to ground anywhere along its length. Do not use grounded
autoformers on the loudspeakers.
