How to Connect two MC58s in Bridge Mode
The MC58 Eight Channel Power Amplifier has a Bridge
Mode, which doubles the power output for each of the four
Stereo Amplifier Pairs. Two MC58s, together with a CR16
provides higher power out for each of the four Zones.
Note: Only Zone One is illustrated below. Follow a similar
procedure for Zones Two through Four on the MC58.
1. Connect the Loudspeaker Cables to the appropriate
Bridged Channel Output Connections, being careful to
observe the correct polarities.
2. Connect a 7 Pin DIN cable from the Power Control
Output of a Multizone Control System to the MC58
MULTI-ROOM Connector (Left Channel Amplifier).
3. Connect a 7 Pin DIN cable from the Multichannel Out-
put of a Multizone Control System to the MC58
