Cut LS Switch
When used this illuminated switch will cut both the front panel loudspeakers
and the analogue and AES3 outputs. It will also cut any of the network output
circuits that are after the cut control.
A rear panel GPI circuit also affects the state of this switch. If the rear GPI
circuit is made (i.e. on) then the switches internal LED will illuminate and
pressing the switch will not turn the cut on or off.
There is a 2
nd
rear panel GPI circuit that can be used to cut just the internal
loudspeakers. If this 2
nd
GPI circuit is made (i.e. on) then the internal
loudspeakers will be cut but the switches internal LED will not be on and this
switch will continue to operate a cut on the analogue, AES3 and network
outputs.
7.
Left Panel Loudspeaker
This internal loudspeaker is fed audio from the left output of the mix/ solo mix
buss. The front panel overall level control adjusts its volume and the front
panel Cut & Dim switches also affect it.
There is a rear panel GPI that can turn the internal loudspeakers off.
Inserting a headphone jack in the headphone socket also turns the
loudspeaker off.

Input Level Control
The level control adjusts the incoming audio level by applying gain/ loss to it.
In its 12 O’clock position it is at unity gain.
Fully clockwise 10.6dB of gain will be applied to the input.
Fully anti-clockwise 30dB of loss will be applied to the input.
9.
Audio Present Indicator
The ‘PRES’ (present) LED indicates to show that valid audio is being detected
on the channel prior to the level control.
It will illuminate when an incoming audio circuit is at -20dBu or above.
Once illuminated it will stay illuminated for 3 seconds after it detects the input
level to fall below -20dBu.
If the Led Flashes this indicates that the input level is either clipping or within
1dB of clipping.
