Caller Set-Ups
Pre-air segment communication between the console operator (DJ)
and callers is via CALLER ANSWER buttons which place the caller’s
voice on the console’s cue speakers and/or control room speakers/
operator’s headphones if the CRD-500 module’s cue interrupt function
has been so programmed.
The caller automatically hears the console operator’s pre-
fader, pre-ON mic signal via the internal TB bus.
Note: During initial console installation, an internal TB monitor
dipswitch must be set on the console operator’s MM-5000 module. Note
that only 1 MM-5000 module can be assigned to the TB monitor bus.
Automatic Features
The channel ON (red, usually labelled “START” for phone mod-
ules) and OFF (amber) switches are at the bottom of the module. These
can be programmed (via internal PCB-mounted dipswitches) to acti-
vate control room and studio mutes, tallies, timer restart and automatic
cue drop-out. The ON/START switch can also automatically trigger an
external tape machine for recording purposes (see top of page 8-8).
Cue Dropout can be programmed internally, making it unnecessary
to de-activate caller setup buttons before going live; simply pressing
the module’s ON/START switch will automatically do this for you.
Inputs and Outputs
All audio and control signals hook-ups are made via two multi-pin
DB-25 connectors mounted in the bottom of the console’s mainframe,
directly underneath each module. The upper connector handles hybrid
input signals (i.e., caller input) and the External input. The lower
connector handles outputs, including the CALLER 1 and 2 feeds to
your station hybrid (the phone signals going to your callers), drop caller
and answer caller control signals.
The module also has three additional output feeds on the lower
DB-25 connector. These are generally used for recording purposes:
Composite Out – This includes everything: DJ, callers, music beds,
etc. Generally used to record phone segments in advance of actual
airplay.
Composite Minus Callers – This includes everything but the callers.
Callers Only – No talent, no DJs, no music; just caller voices.
External In
In addition to feeding the DJ’s voice signal to the callers via the
module’s mix minus source select switching, it may also be brought
directly in through an EXT IN port on the module’s upper DB-25
connector.
