FRONT OF MODULE

Gain Control
The module gain control has a range of -10bB to +30dB using a standard rotary pot for adjustments. Combined with the rear mic/line switch, it gives the module an overall input range of -70dB to +10dB.

Low Frequency Cut
Cut levels can be set to either 80Hz or 160Hz to reduce low frequency rumble commonly found in amplified speech.

Presence Control
Two positions of EQ can be set at either 1K6 or 3K2 to boost or reduce frequencies with an increase/decrease of 10dB (in a bell shaped frequency response) which uses a rotary pot for adjustments. This can be turned off and the frequency left flat.

Pan
For routing audio between the left and right main outputs.

Pre-Fade Listen
This allows the engineer to listen to the modules audio levels before the fader takes effect.

Cut A/B Switch
It allows the channel to be turned on or off. A LED illuminates to indicate cut.

Faders
Faders can be either 60 or 100mm and comes with a Penny & Giles option. All input faders hold 10dB.

Aux Fader
The Aux fader routs the channel output to the aux mix (mono mix). The fader can be set via the toggle switch to be post master fader or pre master fader.

REAR OF MODULE

Mic/Line Input
Balanced XLR input which can be set to mic or line using the toggle switch on the rear of the module.

Phantom Power
48 volt phantom power can be turned on/off using the toggle switch on the rear of the module.

Insert point
Break jacks are located on the rear of the module. The output and input of any channel can be used to over-plug effects such as compressors. Output levels are -10dB which provides greater headroom, useful if being sent to an external compressor.

Channel Out/Clean Feed Out 

Channel Out
Connectors are on the rear of the module. The line output of the module can be selected using the toggle switch located on the rear of the module.

Clean Feed Out
A line out (on the rear of the unit) of everything on the mixer’s main mix less that module. This can be selected via the toggle switch on the rear of the module.

CLS/SLS Loudspeaker Switching
The loudspeaker outputs are on the main module. The internal settings for ‘Cubical Loudspeaker’ (CLS) or ‘Studio Loudspeaker’ (SLS) are provided which determine how these loudspeaker outputs operate when this channel’s fader is opened.

HEADPHONE AMPLIFIER

6 Sources Including Program

CF/CH or Mix
In the mix position, it is the output of the main mix which is routed to the headphone feed. Set to the CF/CH position, it follows the setting of the toggle switch to the rear of module. When set to ‘CH’ only, audio from the input of the channel is routed to the headphone feed. In the ‘CF’ position all the audio on the main mix is routed to the headphone feed but minus that channel’s input.

Cue
Cue comes from two places, with an ISDN module fitted, cue relates to the return audio from the first ISDN codec. The audio from the ISDN codec is routed via the AMO where an insert point is available for over-plugging different audio into this cue circuit. Without the ISDN module, a feed can be inserted directly into the AMO module.

Local
A pair of inputs located on the AMO module is routed to the headphone via this local pot which is fed to all modules. There is also a local input on the rear of the module itself which allows audio to be inserted solely to that headphone amp which over-pluggs the audio from the AMO module.

Speak to Comm and OS/TB
This button routs via the TB level control, the operators mic input to the headphone feed or the clean feed output.

Producers Box
When the producer presses the momentary button on the producers box, the audio (eg. producers voice) is mixed into the right ear only of the headphone feed. Please note, there is no volume control on the module for this source.

Output
Switchcraft A/B Gauge jack socket.

Phase Reverse B Option
By internal link
