A-BUS Outputs [5] A & B
- Each of the A-BUS Outputs provides the power, audio and data
signals to feed a Volume Control Module. There are four output zones; each zone may
independently select from any of the four sources. Each zone has two outputs; Bank A and
Bank B. When one AUDZPS40 A-BUS Power Supply is used with the Hub, the rooms for Bank
A may be powered. A second AUDZPS40 Power Supply can be added to power the Bank B
rooms or alternatively any of the Bank B outputs can used as an expansion port to feed one or
more single-source Hubs.
CAUTION: Only an approved A-BUS 4A Power Supply [11] should be used. Substitutes,
which may appear to be suitable are not recommended and will void the warranty.
IR Remote Control [6]
– At least one AUDZ41RC A-BUS IR Remote Control is needed with the
MDADZHMS Multi-Source Audio Hub. This Remote Control includes a dedicated A-BUS bank and
includes keys for most standard functions. The Remote Control has a code library built in; however,
all keys have learning capability and can also learn multiple commands (macros) including the
mode keys. See separate instructions.
Power Indicators [9]
- The two red power lights indicate when the power supplies connected to bank A
or bank B are active. These indicators do not indicate the system is active (see System Indicator [3]).
DC Power Input Sockets [10]
- There are two power sockets one for each output bank ‘A’ and ‘B’.
12v DC Trigger [12]
- This is a 12v DC output that turns on when that source is selected. The output can
be used to trigger a relay for power control of the source component.
