There are eleven dierent input channels available for installation in the mixer as well as a
blank channel and script space.
The modules carry some common features, such as the ability to select the output as
PRG and/or AUD and each button on a module can be programmed in dierent modes,
depending on your requirements. The channels are each covered in the following chapters,
but a summary follows:
S2-CML Mic/Line Input Channel
The Mic/Line Input channel is a mono input with a button switch to select either Mic or
Mono Line. If the Mic input is used for the presenter’s mic it can also become the talkback
mic. The talkback function will be retained when the channel input is switched to Line.
Equalisation is tted as standard on this channel and is enabled by the EQ button, providing
7dB cut and boost at HF (6.5kHz) and LF (100Hz). The Mic input has a jumper selectable high
pass lter to remove low frequency intrusions. A Pan control is available to facilitate stereo
imaging. A balanced line level insert send and return is available for the Mic input but is
disabled in Line mode.
Channel coarse gain is set by internal presets for mic and line – ne gain is trimmed by the
front panel Trim control providing ± 12dB of gain. The channel has a Pre Fade Listen (CUE/
PFL) facility that can be automatically disabled when the fader is opened. There are logic
remote input controls for Mic Cough muting and Reverse Talkback, and output controls for
Mic cue lights and Line remote start/stop by fader or ON button. The remote outputs on
the 9 way D type plug are fed from NPN opto-isolators. The Mic input provides a jumper
selectable output to facilitate either Control Room or Studio Muting and Timer functions. In
addition the Line input can be congured with all the features of the Mic input when used
as a Mic input with an external mic amp.
S2-CMM Mic/Mic Input Channel
The Mic/Mic Input channel has all the features of the Mic/Line Input channel except that the
Line input is replaced by a second Mic input.
S2-CS Dual Stereo Line Input Channel
The Dual Stereo Input channel has two balanced stereo inputs with a button switch to select
between them. Each input is on XLR connectors with internal coarse gain adjustment. Fine
gain is trimmed by the front panel Trim control providing ± 12dB of gain. A Balance control
is available for small adjustments of the stereo image. The channel has a Pre Fade Listen
(CUE/PFL) facility that can be automatically disabled when the fader is opened.
There are logic remote output controls for each of the two inputs providing start/
stop functions by fader or ON button. The start function can be congured to be either
momentary (500mS) or latched for each input. The remote outputs on the 9 way D type plug
are fed from NPN opto-isolators.
