3.08 The equaliser circuitry can be switched in or out of the signal path by simply
configuring a PCB jumper. This operates independently of the 100Hz high pass
filter.
3.09 Auxiliary Sends
2 auxiliary sends are provided and can be individually configured to operate in
the pre-fade or post-fade mode by simply reversing a PCB jumper (see detail).
This facility can be used to interface a variety of units for signal processing,
sampling digital effects or a flexible extra output facility. Factory settings
configure Aux 1 to be pre-fade and Aux 2 as post-fade.
3.10 Pan Control
This control operates at -3dB at centre, to infinity at the control extremes, with a
centre detent to aid positive central image setting. The pan pot is used to place
the mono signal anywhere within the stereo image.
3.11 PFL (Pre fade listen)
This logic controlled momentary action switch, routes the pre-fade signal to the
headphone amplifier and PFL stereo LED bar graph display. The selection of a
channel PFL automatically cancels any prior selection and the adjacent LED
indicates status.
3.12 Peak LED
A red LED indicates the peak signal level at the pre-fade point and illuminates at
a level of approximately 4dB below clipping.
3.13 Channel Fader
The channel fader has a slide length of 100mm and an exceptionally smooth
feel. Under normal operating conditions, the fader is used fully open in
conjunction with the mute switch.
3.14 Mute Switch
This momentary action logic controlled switch operates silently and consistently
and can be used to conveniently turn the mic channel on and off. The logic
control can be configured with a PCB jumper to operate the booth output mute
function on the M3 Master Module, or the 'AutoMute' Facility on the CZ1.
This mute function operates post insert and mutes all effect sends and PFL. The
jumper is factory set to the 'off' position.
3.15 Insert
A 3 pole 1/4" jack socket is provided on the rear panel. This insert point
operates at a level of 0dBu and is situated post EQ, pre-fade. A variety of signal
processing units can be used for single channel effects such as compression
etc. This can also be used as a direct microphone signal output.
