CH 1–4
Each channel input section has two inputs: XLR input – This
is a balanced microphone input. It has an input sensitivity of
1mV. RCA input – This is an unbalanced line level input. It
has an input sensitivity of 500mV. The two RCA sockets are
summed to mono internally.
2
REC Output
The REC output is on unbalanced RCA connectors. The output
level is 150mV into 10kohm at rated output. The output is
dual mono.
The REC output is not affected by the MASTER volume control
or the BASS and TREBLE controls.
The REC output does not receive the tone signal if the optional
tone generator module is installed.
3
Line Output
The LINE output is on a balanced XLR connector. The output
level is 0.775V into 1k at rated output.
Note:
When wiring the LINE output as unbalanced, Pin2
should be wired as hot and Pin1 should be wired as ground/
shield. Do not wire Pin3.
4
Direct Out
The speaker connections are on the 12 pole terminal strip.
There is a low impedance output (OHM) and a distributed line
voltage output (LINE). 70V out is available on 115V models.
100V out is available on 230V/240V models.
Note:
Only connect one output – either Distributed Line or Low Impedance per channel.
Do not connect LowZ and 70/100V at the same time.
The output strip comes fi tted with a touch-proof cover held in place by two M3 machine screws
with fl at and spring washers.
5
IEC Mains Input Socket
This is a standard IEC 3 pin socket. It accepts a standard IEC mains cable, provided. The fuse
draw at 5 contains the mains fuse and a spare. The mains fuse is a time lag (slow blow)
HRC 20mm x 5mm ceramic type fuse.
Always replace the fuse with one of the same value and type.
Note:
Always disconnect power to the amplifi er before replacing fuses.
6
(Optional) Tone Module
These terminals are for use with an optional tone module (not supplied). Use Australian Monitor
ATC5488 module.
7
Phantom Power
12V phantom power is available for condenser or electret microphones on the XLR input when
this switch is pushed in.
