Output Channels
The S0 has separate stereo PGM and REC bus outputs. The PGM bus is output on balanced
stereo XLRs and the REC bus is output on unbalanced stereo RCA phono connectors. There
are monitor outputs for presenter headphones, guest headphones and loudspeakers.
Monitoring & Headphone Limiter
The monitor loudspeakers, presenter headphones and guest headphones are on 6.35mm
stereo jack sockets and the headphones can be plugged in to the front and rear of the mixer.
The monitor loudspeaker and headphone levels are independently variable between 0 (cut
off ) and 10 (max).
With the concerns over listening levels being too high in headphones, the addition of an
adjustable limit level potentiometer on the rear panel of the mixer is a great idea which
limits the maximum level of the audio routed to the presenter and guest headphone
outputs. An illuminated MUTE LED shows when a live microphone channel has muted the
loudspeakers and there is a MUTE contact output available to illuminate a ‘MIC LIVE’ light via
a 6.35mm stereo jack socket on the rear panel.
A three way electronically interlocking illuminated switch bank selects the source routed
to the loudspeaker and headphone outputs from either PGM, REC or from an additional
unbalanced stereo RCA phono input EXT 1. This external input can be used for monitoring
an off air signal or studio output.
Green illuminated AUTO CUE/PFL (pre fade listen) buttons adjacent to each level control
allow the automatic monitoring of any channel that has been selected to pre-fade, either to
the monitors or headphones.
For the presenter headphones, SPLIT CUE/PFL can be selected which places the selected
source in mono in the left ear, and pre-fade in mono in the right ear.
Metering
A pair of bright 21 segment LED meters can be configured to show either VU or PPM
metering. The meters follow the selection of the presenter headphones including any pre-
fade or split pre-fade function.
Talkback
A separate TALKBACK button is provided to allow the presenter to talk to a guest on the
guest headphones. The S0 uses input channel 1 as the talkback source.
Channel Remotes
The remote outputs for each channel are highly configurable providing a comprehensive
range of options to interface external equipment to the mixer. Each channel input has its
own START and STOP remote controls which can be triggered when the channel is routed
to the PGM or REC bus and the fader is opened or closed. The remotes can be set-up to be
either pulsed or continuous latched outputs, and if in pulsed mode the START button has
the capability to produce repeated start pulses.
