Superphone Input (SPD-220)
Module Overview
SPD-220 input modules are used for telephone call-ins. Each module
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), AUX (auxiliary) and/
or UTL (utility).
Caller Set-Ups
Pre-air segment communication between the console operator (DJ)
and callers is via TB/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-220 module’s cue interrupt function has been so programmed).
These cue signals can be internally programmed pre or post fader.
The caller hears the DJ in one of two ways:
1) The DJ can assign his microphone input module to an unused output
bus—say UTL—and the DJ then selects the UTL input with the CALLER
FEED switch. This sends a dedicated (digitally generated) version of the
UTL bus signal to the SPD-220 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-220 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
Utility 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 Utility output bus regardless of fader or ON/
OFF settings on his mic module (which must still be assigned to UTL, how-
ever).
2) The DJ’s voice signal can be inputted through a special EXT IN port
at the SPD-220 module’s DB-25 connector. This second method elimi-
nates the need to select a mix minus input source everytime you want to
talk off-air to the caller. An easy source choice here would be DJ mic
module’s INSERT OUT port.
