REAR PANEL GUIDE
8
AC Power Socket:
IEC socket, with integral fuse and power switch.
9
Speaker Terminals:
Plug in terminal clamp connectors accept 1.5mm² speaker wires
10
Preamplifier Outputs:
Audio and composite video outputs. Gold plated RCA connectors.
11
RS232 Comm Port:
DB9 connector. The port is used to setup, control or monitor the
AX4752
. A null modem cable must be used when connecting to a PC or building management
system.
12
Expansion Bus Output:
34 way IDC header. Connects to the expansion bus input of the
next AX4752i amplifier in the stack.
13
Paging & Status Terminals:
9 way Plug in terminal clamp connector.
A short between PG and 0V invokes the ‘Page’ preset, making possible telephone paging
through the multi-zone system.
AMP-ON 1, 2, 3, 4 pr12VDC when the preamplifier or amplifier zone is ON.
AMP-ON # is +12VDC whenever any of the zones are ON.
Terminals C & D are Axium Bus connections for operation of the Axium KRX membrane
keypads.
14
Controller Interface:
4 way green plug in terminal clamp connectors, used for connecting
to
Keypads & IR receivers. There are two controller interface ports each linked with an IR port
providing IR routing. The +12VDC output is internally fused (self-resetting), and has a
maximum loading of 4 Axium keypad’s or IR receivers. The ‘Data’ terminal sends amplifier
status to Axium keypads.
15
Routed IR Emitter Ports:
3.5mm mono phone jacks. IR1 & IR2 are used to control specific
source components. The ports only output IR strings received from their associated controller
interface.
16
IR Emitter Ports:
3.5mm mono phone jacks. The two jacks labeled IR1+IR2 are for control
of source components common to all zones. They output the combined IR1 & IR2 IR strings.
17
+12VDC Center Positive Outputs:
For powering the AX07S slave amplifiers.
18
Expansion Bus Input:
34 way IDC header. Connects from another Axium amplifiers
expansion bus output – provides connection of source component audio, control, & IR.
Note: Video does not go up the expansion bus lead.
19
Source Component Connections:
Gold plated RCA jacks. Source component line level
and composite video inputs.
