Control Room Logic
This 14-pin connector has two isolated relay contacts (on pins 4 and 5) which are used to control a warning
lamp interface like the Harris Broadcast WL-2 or Henry Superelay. The warning relay is activated whenever
any channel with a Control Room mic as its source is turned on and assigned to a Program bus. This action
also mutes the Control Room Monitor audio output.
These are the other three logic outputs, which are all commoned together on pin 10:
●
CR dim on pin 12 (active when receiving talkback)
●
CR mute on pin 11 (active when a CR mic is hot)
●
Talkback on pin 13 (active when Talk to CR is being received)
You can use these outputs to control external speaker switching circuitry, for tally indicators, or to trigger an
air skimmer or other recording device.
There are two external logic inputs you can use to remotely dim the monitors (pin 9) or to mute the
monitors (pin 8). To use these inputs, you must tie pin 14 high (+5 to +40 VDC). The logic inputs are
triggered by being pulled low.
Studio Logic
This 14-pin connector has the same connections as the control room, except they are for a talk studio or
voice booth. There are two isolated relay contacts (pins 4 and 5) for controlling a warning lamp interface like
the Harris Broadcast WL-2 or Henry Superelay. The connector is activated when any channel with a studio
mic as its source is turned on and assigned to a Program bus. This action also mutes the Studio Monitor
audio output.
These are the other three logic outputs, which are all commoned together on pin 10:
●
Studio dim on pin 12, active when receiving talkback
●
Studio mute on pin 11, active when a Studio mic is hot
●
Studio talkback on pin 13, active when Talk to Studio is being received
You can use these outputs to control external speaker switching circuitry, for tally indicators, or to trigger an
air skimmer or other recording device.
There are two external logic inputs you can use to remotely dim the monitors (pin 9) or to mute the
monitors (pin 8). To use these inputs, you must tie pin 14 high (+5 to +40 VDC). The logic inputs are
triggered by being pulled low.
Channel Logic
There are eight 12-pin Channel Logic connectors on each DSP card. They typically connect remote mic
control panels (using Mic logic with On and Off Tallies) or peripheral devices (using Line logic with Start and
Stop Pulses). The Function parameter setting determines the type of logic used (Mic or Line). Mic logic is
used when one of these parameters is selected:
●
CR MIC
●
CR MIC TLK SRC
●
STU MIC
All other Function settings use Line logic.
Note: The Tally Output Mode sends Tally commands (on/off tallies instead of start/stop pulses)
for Line logic on all DSP card logic connections. This mode is active when the Option 2
LED is lit on that DSP card.
