SUPERPHONE INPUT
Superphone Input
(SPD-70; optional)
Module Overview
The SPD-70 input module is used for telephone call-ins, and can handle
two callers. Caller signals enter the module from your station hybrid; each
caller has its own fader.
Output switches assign callers to any combination of the console’s four
stereo outputs: PGM (program), AUD (audition), AUX1 and/or AUX2
(auxiliary).
Caller Set-Ups
Pre-air segment communication between the console operator (DJ)
and callers is via CUE buttons (2) which place the caller’s voice on the
console’s cue speakers (or control room speakers/operator’s headphone if
the CRD-70 module’s cue interrupt function has been so programmed).
These cue signals can be internally programmed pre or post fader.
The DJ can assign his microphone input module to an unused output
bus—say AUX2—and the DJ then selects the AUX2 input with the MXM
SOURCE switch. This sends a dedicated (digitally generated) version of
the AUX2 bus signal to the SPD-70 module’s hybrid output, where it is
ultimately heard by the caller through his telephone. This mix minus
source select method can also be used to preplay a musical segment (or any
other program content) for the caller off-air. Take the IND-70 input
module handling the desired music cut and assign it to an unused output
bus; select the same bus as the caller’s mix minus source input and he will
hear it off-air.
Microphone input modules can be internally programmed to have their
AUX2 bus feed tapped pre-fader, pre-ON/OFF, making this a logical set-up for
the DJ’s mic input if you do a lot of call-in work, since the DJ’s voice will
always be present on the console’s AUX2 output bus regardless of fader or ON/
OFF settings on his mic module (which must still be assigned to AUX2, how-
ever).
