Aux Master

1

The Aux Master control sets the output level of
the combined input Aux Sends.  The output is
unbalanced at a nominal 0dBu.

2

The input Aux Sends may be globally switched
to be pre-fade (for foldback, switch released) or
post-fade (for effects, switch pressed).  Note
that when the Aux Send is switched to the
Channel path (‘INPUT’) this switch has no effect.

Stereo Return

3

The balanced Stereo Return, on 3-pole jacks, is
an ideal place to connect the output of an

Effects unit.  The Fader sets the level of the sig-
nal fed directly to the MIX. 

4

When the PFL switch is pressed, a mono pre-
fade signal is fed to the Monitor/Phones out-

puts, where it replaces the selected source. The

meters follow the monitor source to display the

PFL signal.  The SOLO LED lights to warn that

the monitor and meters are now responding to

the PFL selection. 

Mix Outputs

5

Two Faders control the output level of the stereo

Monitor Mix.  The outputs are balanced on XLR-

3 connectors at a n4dBu, or -10dBV

on RCA phono connectors.

Monitoring and Metering

6

The stereo monitor outputs (3-pole jacks) and
phones output may be sourced from four signals,

selected on these switches.  The source may be

the 2Track Tape Monitor (balanced on 3-pole XLR

at +4dBu, or unbalanced on RCA phone at -
10dBV), Aux output, Tape Returns on inputs 7 & 8
(MON 7/8) or the stereo Mix output.  In all cases

the meters follow the monitor selection.
When a PFL is active, the selected monitor

source is replace by a the mono PFL signal on
both meters and both sides of the monitor and
phones.  The SOLO LED lights to show that a
PFL is active.

7

The Phones and Monitor outputs are controlled
by the MONITOR/PHONES control.

8

A standard 3-pole ‘A’ gauge jack socket feeds
headphones (100

W

or greater).  The monitor

outputs are muted when headphones are con-
nected.

9

Two 8-segment LED Bargraph meters display
the level of the selected monitor source or PFL

when active.

Limiter

10

The seven position switch sets the common
threshold of the built-in fast Limiter on each

input channel.  This should be set to 1-2dB

below the clipping level of the tape machine.
Note that although the threshold is set globally,

the Limiter on each channel may be activated

individually.

11

The main Power switch for the mixer.  The LED
illuminates when power is switched on.
