Multiple MZA-4.7 Stacks
In large installations where multiple MZA-4.7’s are required, the expansion bus may be used to convey inter-amplifier
control, source component Audio, and IR.
Fig 4 shows inter-connected amplifiers using an expansion bus lead. The source component audio inputs must be
plugged into the first MZA-4.7, where they are buffered and sent to the next amplifier in the stack. The maximum
recommended expansion is eight units.
If connecting serial RS232 only one connection to any amplifier is necessary.
