Part Names and Functions —Continued
A AC INLET
IEC socket.
B Speaker Terminals
Plug in terminal clamp connectors accept 1.5mm 2
speaker wires.
C ZONE PREOUT
Audio and composite video outputs.
D RS232 Comm Port
The port is used for setup, control or monitoring.
The interconnecting cable must be straight: 9 pin
‘D’ connectors.
E EXPANSION BUS OUTPUT
34 way IDC header. Connects to the expansion bus
input of the next MZA-4.7 in the stack.
F AMP ON CONTROL
A contact closure between the PG and 0V terminals
invokes the Page preset, enabling paging or doorbell
activation.
AMP-ON 1,2,3 and 4 output 12VDC when the
Zone preamplifier or amplifier is ON, while
AMPON # is 12VDC when any of the zones are
ON.
G Controller Interface
For connecting to keypads and IR receivers. There
are two controller interface ports:
KEY PAD1 and 2, and each are linked with an IR
emitter port providing IR routing.
The +12VDC output is internally fused – self-reset-
ting – and has a maximum load of four Keypad or
IR receivers. The Data terminal sends amplifier sta-
tus to the Keypads.
H Routed IR Emitter Ports
3.5 mm mono phone jacks. IR1 and IR2 are used to
control specific source components. The port is only
output IR strings received from their associated
controller interface.
I IR Emitter Ports
3.5 mm mono phone jacks. The two jacks labeled
IR1+IR2 are for control of source components com-
mon to all zones. They output the combined IR1
and IR2 IR strings.
Codes supplied from KEY PAD1 will not present
on IR2. Codes supplied from KEY PAD2 will not
present on IR1.
J 12V OUT
The connectors supply 12VDC 1Amp max. Centre
Positive, 2.1mm pin diameter.
K EXPANSION BUS INPUT
Connects with another MZA-4.7’s expansion bus
output – provides connection of source equipment
audio, control and IR.
L INPUT Terminals
Source component line level and composite video
inputs.
