Front Panel Controls
From top to bottom, the individual module controls are as follows:
MIC A/B switch — Selects between microphone A and B.
MIC A GAIN pot — Continuously variable; used to match input levels from
one module to the next.
PHANT switch (two: A and B) — Switches microphone phantom power on
and off.
PAD switch (two: A and B) — Attenuates (–20dB) the signal feeding the
microphone input; used to control extremely loud source material and prevent
it from overloading the module's microphone input circuitry.
MIC B GAIN pot — Continuously variable; used to match input levels from
one module to the next.
PHASE switch — Reverses the polarity of the microphone inputs.
HPF high pass filter switch — Introduces a high pass –12dB/octave roll-off
at 125Hz; used for removing unwanted low frequency content from source
signals.
EQ — 3-band semi-parametric with one concentric control for each band.
Each band continuously va/–16dB with continuously variable center
frequency. Frequency ranges are high: 800Hz–16KHz; mid: 400Hz–8KHz;
low: 40Hz–1KHz. 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
(does not affect HPF switch).
PAN pot — Pans the module's mono signal between the left and right
channels of the console's stereo output (L/R assign switch must be engaged; see
below)
BUS ASSIGN switches — Assigns the input module's signal to the console's
submaster and stereo master modules.
SEND controls — 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
be 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.
CHANNEL ON/OFF switch — With integral LED indicator.
SOLO switch — Sends the modules post-fader signal to the console's solo
bus, where it may be programmed to automatically interrupt contol room and/
or headphone monitor ouputs
CUE switch — Sends the module's pre-fader signal to the console's 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 output level.
