Adding a 12-Channel Amplifi er
HIGH-POWER ALL ZONES
Another option for adding external amplifi cation, is to connect each of the MZC-66 Zone Pre-Outs directly to the individual
line-level inputs on a SpeakerCraft high-power multi-channel amplifi er. This option maintains individual zone control via
Keypads, as in a normal MZC-66 system, but now cranks up the audio power to each zone.
1. Using a quality stereo RCA to RCA cable, connect the Zone L & R Pre-Outs to the appropriate L & R line level inputs
(i.e. Channel pairs 1 and 2, Channel pairs 3 and 4, etc.) on the multi-channel amp.
2. Set the VC/NVC Switches on the MZC-66 Rear Panel to VC (variable) so the zone keypads can be used to adjust
volume.
3. Connect zone speakers to the multi-channel amplifi er Speaker Terminals in the same pairings as the Pre-amp connections.
4. Switch the BUS/AUX/LINE Input Select Switch on the multi-channel amp to LINE for all channels connected to MZC-
66 Pre-outs.
5. Connect a Trigger Input to the multi-channel amp for Power ON/OFF as described in 12V Trigger (System Activity),
previous.
