Adding a 12-Channel Amplifier
HIGH-POWER ALL ZONES
Another option for adding external amplification, is to connect each of the MZC-88 Zone Pre-Outs directly to the individual
line-level inputs on the SpeakerCraft DBB 12100, 100 Watts by twelve channel amplifier. This option maintains individual
zone control via EZ-Pads, as in a normal MZC-88 system, but now cranks up the audio power to a massive 100 Watts per
channel in up to six zones!
1. Using a quality stereo RCA to RCA cable, connect the Zone L & R Pre-Outs to the individual line level inputs on the
DBB12100. (The DBB12100 inputs are labeled 1-12, so Zone 1 would use inputs 1&2, Zone 2 would use 3&4, etc.)
2. Set the VC/NVC switch on the MZC-88 Rear Panel to VC (variable) so the zone keypad can be used to adjust volume.
3. Connect zone speakers to the DBB 12100 Speaker Terminals in the same pairings as the Pre-amp connections.
4. Switch the BUS/AUX/LINE Input select switch on the DBB12100 to LINE for all channels connected to MZC-88 Pre-outs.
5. Connect a Trigger Input to the DBB 12100 for Power ON/OFF as shown in Figure 21.
