Internal Programming Options
All internal programming is made via printed circuit board (PCB)
mounted switches on the module’s main card. With the exception of insert
bypass, which is a single-throw slide switch, all programming is via 4-
position dipswitches (total six).
For the purposes of this manual, we will assume you are holding the
removed 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 program-
ming switch. Note when a dipswitch position is thrown to the right
(towards the module’s faceplate) it is ON.
Insert Bypass
SW7 (a single throw slide switch right next to the card’s short upper
row of gold fingers) will click the module’s insert point in and out of the
audio signal chain. Note again that the factory default is “insert bypassed”.
In other words, when shipped from the factory SW7 is thrown in the
direction of the silkscreened arrow on the PCB (to the left). To use the
insert point (see “Audio Connections” page 2-5), throw the switch to the
right, towards the module faceplate.
Phantom Power
Four-position dipswitch SW1 (upper right corner of card) turns phan-
tom power on and off for the module’s two microphone input ports.
Dipswitch position 1 activates phantom power for microphone A
Dipswitch position 2 activates phantom power for microphone B
Mutes
When a microphone is live in a room, that room’s monitor speakers
must be muted to prevent feedback. The RD-12 console has three mute
control lines: control room, studio one and studio two. Each of these may
be activated by either an A or B microphone input. The first three positions
of dipswitches SW3 and SW4 (to the left of the fader) program these
muting functions:
SW3 position 1 mutes the control room when mic A is live*
SW3 position 2 mutes studio one when mic A is live
SW3 position 3 mutes studio two when mic A is live
SW4 position 1 mutes the control room when mic B is live
SW4 position 2 mutes studio one when mic B is live
SW4 position 3 mutes studio two when mic B is live
Timer Restart
The console’s digital timer can be programmed to automatically reset
to zero and begin counting up when the module’s ON button is pressed.
SW3 position 4 activates timer restart for mic A
SW4 position 4 activates timer restart for mic B
?
Note the factory default
setting for phantom power
is OFF.
