Superphone Input
(SPD-8; optional)
Module Overview
SPD-8 input modules are used for telephone call-ins. Each
module can handle two callers; there can be two modules per
console for a total of four callers. Caller signals enter the module
from your station hybrid; each caller has his own fader. Caller input
gain trims are provided at the top of the module.
Output switches assign callers 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 “Air” LED illuminates just above the
output assign switches.
Caller Set-Ups
Pre-air segment communication between the console operator
(DJ) and callers is via CALLER SETUP buttons (2) which place the
caller’s voice on the console’s cue speakers (or control room
speakers/operator’s headphone if the CRD-8 module’s cue inter-
rupt 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 MXM SOURCE switch at the top of the phone module. This
sends a dedicated (digitally generated) version of the UTL bus
signal to the SPD-8 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 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.
Remember IN/INM/INDM-8 input modules can be internally pro-
grammed 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, however).
2) The DJ’s voice signal can be inputted through a special EXT
IN port at the SPD-8 module’s DB-25 connector. This second
