Master Audio Facilities - Solid State Logic SL 9000 J Series Operator's Manual

Console Overview

Master Audio Facilities

The SL 9000 J master audio facilities are built to a completely new design, offering high
performance, low noise, high bandwidth and low distortion. The controls provide all
of the functionality of a G Series centre section, plus master facilities for the additional
Auxiliary and Stereo Subgroup busses. The foldback and external source selection
systems are substantially refined and extended. Additional switching for the new Solo
modes is provided.
The main console output is 4-channel with a 4-channel fader and compressor. The
output is provided with a pre-fade insert point. The compressor is identical to the
design used in the G Series range. Selecting KEY bypasses the pre-fade insert point
and allows the insert return to be used as a key input. The Master Fader has it's own
status button and LEDs. The OFFSET control allows the Master Fader level to be
adjusted while still leaving the Master Fader at the top of its travel.
The Left and Right Main outputs are fed from console-wide busses. If the LCR Film
Pan option is fitted, then the Centre bus can also be fed directly from the channels. The
four Stereo Subgroup busses can also be re-routed back to the Left/Right, Centre and
Surround outputs, allowing four-channel mixes to be built up even if the console does
not have the LCR panning option fitted. The Centre and Surround outputs are fed by a
mono sum of the selected Stereo Subgroup bus.
The main monitor output is 4-channel with a switchable insert point, pre the monitor
level control, for Dolby Surround encoders/decoders. Two pairs of near-field monitor
outputs are also available, and can be selected using the MINI A and MINI B buttons.
The monitors are normally fed by the desk main output, but this can be replaced by
either one of two External Source selector banks by selecting EXT 1 or EXT 2. The
External Source selectors have independent sources, unlike the SL4000. The buttons
are normally intercancelling, but selecting SUM allows several sources to be
monitored together. LINK connects both source selectors together, for comprehensive
multiple-source selection.
The Auxiliary bus outputs are provided with level control only.
The Studio monitor system has been substantially extended. Three stereo Foldback
and one stereo Studio Loudspeaker outputs are provided. Each is provided with level
control and can be fed by any one or a mix of External Source Selector 1, External
Source Selector 2, or an external signal fed via the patchbay. For the Foldback outputs
this is normally the Stereo Cue output, but this may vary from desk to desk. For the
Studio Loudspeakers, the third source is always the stereo main Mix output.
The four stereo Echo Returns are similar to those fitted on the SL4000, with the
addition of discrete routing switches to the main outputs. Note that the STUDIO level
control feeds signal back to the Foldback outputs - not the Auxiliary busses.
Oscillator and Talkback level controls are similar to those found on the SL4000.
