Front Panel Controls
From top to bottom, the individual module controls are as follows:
LEFT (and RIGHT) TRIM pots — Center detented, +/–15dB, allow
continuously variable adjustment of left and right line input levels.
INPUT A/B switch — Selects between the A and B stereo line input
connectors.
EQ — 3-band with one continuously va/–16dB rotary control for
each band. Each band with switchable center frequency: high is 10KHz/5KHz;
mid 41KHz/500Hz; low 100Hz/50Hz. Equalization curves are reciprocal,
allowing previously applied equalization to be subsequently removed.
EQ IN switch — Switches the 3-band EQ controls in and out of the circuit.
BAL pot — A balance pot used to center the stereo image.
BUS ASSIGN switches — Assigns the input module's signal to the console's
submaster and stereo master modules.
MODE switch — Successive pushes on the Mode switch cause the module
to go from stereo, mono (L+R), left to both channels and right to both channels.
SEND controls — A mono version of the module's signal can be routed to
the console's four send busses via these rotary controls; each send control can
tap the module signal PRE or post fader via individual switches. Note the Send
function may programmed to follow the module's ON/OFF switch (see "Internal
Control").
PK peak LED indicator — Lights to show overload conditions within the
module's circuitry (monitors both pre and post fader signals).
SIG LED signal indicator — Lights to indicate signal presence.
READY LED — A tally indicator that can be lit from an external source
machine.
SOLO switch — Sends the module's post-fader signal to the console's stereo
solo bus, where it may be programmed to automatically interrupt control room
and/or headphone monito ouputs (see "Monitor Modules" chapter).
CUE switch — Sends the module's pre-fader signal to the console's stereo
solo bus, where it may be programmed to automatically interrupt control room
and/or headphone monitor outputs (see 'Monitor Modules" chapter)
MUTE ASSIGN switches — The SP-8 console has two master mute
switches (A & B, located on the stereo master module). Individual inputs may
be assigned to either of the two master mute circuits, allowing groups of
channels to be activated and de-activated with the push of a single switch.
MIX-MINUS ASSIGN switches — The SP-8 console has four mix-minus
busses; each input module may be switched to any combination of the four
busses. When a switch is activated the module's signal is "minused" out of that
particular bus's mix.
FADER — Controls the module's stereo output level.
