Internal Programming Options
There are five user-programmable jumpers on the CRD-220 located on
the center of the module’s PCB card to set various cue interrupt modes and
cue mute (see below).
For the purposes of this manual, we will assume you are holding the re-
moved module upright, component side towards you, with gold-plated card
fingers to the left and the module faceplate to the right. This will enable you to
read the control legends silkscreened next to each programming jumper.
Cue Interrupt
Jumpers J2, J3, J4 and J5 determines how the console’s Cue function
will interrupt regular monitor signals:
J5 sends cue to CR left
J4 sends cue to CR right
J3 sends cue to HDPN left*
J2 sends cue to HDPN right*
Cue Mute
As Cue is also fed to the console’s built-in meterbridge speakers, where
it can easily be picked up by the console operator’s microphone, there is
provision to mute Cue whenever that mic is live (i.e., whenever the control
room mute function is activated).
Jumper J1 will mute cue whenever CR is muted (this is the factory
default setting)
Hook-Ups
As stated before, all user wiring to and from the CRD-220 module takes
place at two DB-25 multi-pin connectors mounted at the top of the module.
Upper DB-25 “A” Connector — Audio
Includes cue, headphone and control room outputs. All audio signals
are +4dBu balanced, analog stereo.
