Stereo Line Input (SL-5000)
Module Overview
SL-5000 modules are for stereo line input signals.
They are available in two different versions. Each module accepts two
stereo sources: A and B, switched at the top of the module. The MODE
SELECTION enables the module to operate in stereo, mono, left only, or
right only. The MODE button illuminates red when set to STEREO;
MONO (L+R to both channels), LEFT to both channels, and RIGHT to
both channels. Being electronic, mode selection is lossless and click-free.
When in MONO mode automatic gain compensation occurs to offset
mono summation.
Output switches assign the selected source signal to any combination
of the console’s four stereo outputs: PGM (program), AUD (audition),
AUX (auxiliary) and/or UTL (utility). When the module is assigned to
PGM and turned ON, a red “On-Air” LED illuminates just above the
output assign switches.
Each input module can feed one or both of the internal mix-minus
busses and the selected send can be pre or post fader and ON/OFF switch.
Front panel tallies let the operator know at a glance which busses are
assigned.
A CUE switch places the module’s signal on the console’s stereo cue
bus, where it may be heard on the meterbridge mounted cue speakers and/
or as an interrupt to the console operator’s headphones and control room
monitor speakers. The various cue interrupt modes are programmed at the
console’s CRD-500 (Control Room) module via internal PCB-mounted
dipswitches. See page 5-3.
Channel ON (red) and OFF (amber) switches are at the bottom of the
module. In addition to being controlled remotely, these can also be
programmed (via internal PCB-mounted dipswitches) to perform a
variety of functions, including starting and stopping external source
machines, activating control room and studio mutes, external tallies, and
timer restart. The OFF switch’s LED can be controlled by an external
source machine to act as a “ready” indicator.
All audio and control input and output signals are made via two multi-
pin DB-25 connectors mounted in the bottom of the console’s mainframe,
directly underneath each individual module.
A Direct Output (post fader, post ON/OFF) is also available.
