VDT Programming Options
Mutes, timer restart, cue dropout, local/ready, tallies, and utility bus
pre-fader programming are made via Virtual Dip Switch Software (see
Chapter 6).
Hook-Ups
As stated before, all user wiring to and from IND-220 modules takes
place at DB-25 multi-pin connector mounted on the top of each module.
There is one connector per section of the double wide module. A pinout
drawing on page 2-9, 2-10 and 2-11 shows all wiring connections at a
glance.
Microphone Inputs
Audio Connections
These include A and B mic inputs, and insert in and out. The mic input
level is nominally -50dBu. Insert points are +4dBu balanced in and out. All
signals are analog mono.
Pin 25 – Mic A In SH
Pin 24 – Mic A In HI
Pin 12 – Mic A In LO
Pin 11 – Mic B In SH
Pin 10 – Mic B In HI
Pin 23 – Mic B In LO
Pin 22 – Insert Out SH
Pin 21 – Insert Out HI
Pin 9 – Insert Out LO
Pin 8 – Insert In SH
Pin 7 – Insert In HI
Pin 20 – Insert In LO
Note the insert points are normally bypassed by PCB-mounted jumper
J1 (see page 2-3). The Insert Out pins may be used as a channel direct
output if desired.
Control Connections
These include remote on and off, cough, talkback and tally functions.
Note each function is available for A source port, allowing it to follow the
module's A mic selector switch.
Pin 1 – Cough A
Pin 2 – Off Tally A
Pin 3 - Remote Off A
Pin 4 – Digital Ground
Pin 5 – +5V Digital
Pin 6 – Tally B
