Stereo Cue Sends
Each mono channel can access two Stereo Cue sends with independent Level and Pan
controls. The ‘ON’ switch sends the channel signal to the cue bus indicated by a green LED.
Both sends are fed from channel pre-fade, post-insert, but can be switched to Post Fader by
engaging the corresponding CUE POST switch in the Foldback master section.
The channel signal is unity gain to the Cue Bus when the Send Level control is fully clockwise
and the Pan control is hard left or right. The centre Pan level is -4.5 dB from 0 dB to each bus,
- a traditional SSL compromise between typical mono -3 and -6 dB centre points for constant
perceived level or power.
Stereo Cue 1 can switch source from the channel signal to an alternate input on the DB25 IN/
RETURN connector. This source is switched using the ALT switch next to the Cue’s Pan control.
This allows an additional input per channel to be summed to the Main Mix Bus, with independent
Level and Pan controls. This control is also adjacent to the path Fader to ease its use as an
additional mix input. Wiring details are in the Connectors section, later in the document.
Channel Fader and Pan
The channel signal level is controlled by a high quality 100mm fader. The Pan pot directly above
this pans the signal to the Main Mix Bus. Next to the Fader is the Channel Meter, as well as the
channel Mute/Bus B switch and PFL switch.
The Fader law is designed to provide more resolution around the 0 dB point, allowing subtle
level changes from modest fader movements. The fader output is unity gain to the bus when
the Pan control is hard left or right. The centre Pan level is -4.5 dB from 0 dB to each bus.
The Mute/Bus B switch mutes the channel feed to the Main Mix Bus, whilst also sending the
channel signal post-fader to the additional stereo Mix Bus B.
The PFL (Pre Fade Listen) switch sends the channel signal to the PFL bus and interrupts the
monitor bus without affecting the main signal output to the Main Mix Bus.
The eight LED Channel Meter is fed from before the fader but after the channel processing. The
fast response peak meter has dened segments for +24 dBu and +18 dBu as well as 0 dBu.
The meter has a fast ‘peak’ response (rise time to 60% Full Scale Deection approx 1 ms @ 1
kHz), and a slower release time to meter peaks while still showing useful signal levels.
