The sub group output appears on the output terminals on the input terminals of all 24
Sub to Matrix potentiometers. The wiper of each pot is connected to a Matrix mixing
bus. The bus to which each pot is connected is shown on the front panel.
Sub to Matrix routing is done by turning the appropriate potentiometer clockwise.
When the potentiometers are turned fully anti-clockwise, no signal is sent to any of
the Matrix Group busses.

This 20 segment LED meter reads the audio signal level, post the Sub group fader.
814147 0DWUL[#35(#VZLWFK#+SURJUDPPDEOH,
The Matrix PRE switch allows you to send the Sub Group mix direct to the “Sub to
matrix” potentiometers, “pre” the Sub group fader. This means that the Sub Group
signal level to the matrix pots is constant and the Sub Group fader only controls the
signal at the sub group output XLR.
814148 6XE#*URXS#,QVHUW#+SURJUDPPDEOH,
All sub groups have a break jack facility placed after the mixing amplifier and before
the output level fader. This is to allow the sub group signal to be sent out to and
returned from an external processing unit. A relay is used to switch the INSERT func-
tion IN and OUT. The relay is controlled by the insert (INS) switch. When the insert
switch is not selected, the sub group signal is passed directly from the input terminal
of the output fader.
Press INS to divert the signal to an external device and have the processed signal
inserted into the Sub Group path.
814149 6XE#*URXS#3)/
A PFL switch is provided on each sub group to allow the operator to instantaneously
monitor the audio signal in the group.
81414: 6XE#*URXS#0XWH
A Mute switch is included on each sub group to allow the operator to instantaneously
switch off the audio signal without disturbing the setting of the out sub group fader.
81414; 6XE#*URXS#)DGHU
The sub group output level is set by a 100mm Penny & Giles conductive-plastic fader
offering a +10dB gain at its fully open position.

Eight segment LED display used to identify each DC Master; this is programmed off-
line using the automation software.

When MUTE is ON the channel faders controlled by the DC group are indirectly
muted.
