STEREO LINE INPUT
Internal Programming Options
All internal programming is made via PCB mounted switches on the
module’s two printed circuit boards.
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 switch. Note
when a dipswitch position is thrown to the right (towards the module’s face-
plate) it is ON.
Mutes
Like MMD-5 inputs, an SLD-5 module can be programmed to mute
studio speakers when the channel is ON. 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 input source. 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 source A is ON
SW3 position 2 mutes studio one when source A is ON
SW3 position 3 mutes studio two when source A is ON
SW4 position 1 mutes the control room when source B is ON
SW4 position 2 mutes studio one when source B is ON
SW4 position 3 mutes studio two when source B is ON
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 when source A is turned ON*
SW4 position 4 activates timer restart when source B is turned ON
Cue Dropout
Dipswitch SW5 position 1, when activated, will cause the module’s
CUE function to be de-activated whenever the channel ON switch is
pressed. This is the factory default setting.
Local/Ready
The module’s channel OFF switch normally has its LED indicator
controlled by the switch itself (“local”). This is the factory default setting.
However, should you wish to have the LED function as a “ready” light for
an external source machine, dipswitch SW5 position 2, when thrown to the
left (away from the faceplate) passes control to opto-isolated A and B
“ready” ports on the module’s AMP D connector where a 5 volt signal
applied with correct polarity will activate the OFF switch LED. As long as
the voltage is maintained, the LED will be lit.
