Logic And Control Wiring - AudioArts Engineering R-5 Owner's Manual

See next page for a diagram
showing typical mic input channel
logic connections.
Note only ONE microphone
!
channel may be programmed
for TB to STUDIO!
If you have not done the
modification described on page
A-10, the studio level will DIM by
15dB instead of
completely.
If desired, the console's CUE
bus (and hence any TB-to-CR
signals) can also be programmed
to interrupt the control room
sreakers. See CUE-TO-CR,
page 6-6.
The mic input ON TALLY may
also be used to drive an external
logic circuit. If the external circuit
will include additional lamps or
relays, these must be powered
from a separate supply. See
APPENDIX, page A-2, for a
recommended circuit.

Mono Mic Input (Logic and Control Wiring)
Mono mic input channel control connections are made at the channel's
UPPER12-pin LOGIC connector. Available control functions are as follows:
Pin 1 - TB TO STUDIO (jumper to pin 2 to activate)
Pin 2 - TB TO STUDIO
Typically one of the console's mic channels will be devoted to the control
room (console operator's) mic and the other to an additional studio. If the
mic channel you are wiring is for the control room mic, you would logically
want it to be able to talk back to the additional studio. By jumpering pins
1 and 2 together, a pre-fader, pre-on/off microphone signal for this input
channel will appear at the console's studio monitor output when the
console's TALKBACK button is pressed. (See TB, page 6-4).
Pin 3 - CR MUTE (jumper to pin 4 to activate)
Pin 4 - CR MUTE
If the microphone input channel you are wiring is for the control room
mic, you will probably want the console's control room monitor output to
mute whenever that mic is on-the-air to prevent announcer feedback. This
can be accomplished by jumpering Pins 3 and 4 together; whenever the
channel's ON button is pressed, control room speakers will mute.
Pin 5 - STUDIO MUTE (jumper to pin 6 to activate)
Pin 6 - STUDIO MUTE
If the channel you are wiring is devoted to a studio mic, you can make the
muting
console's studio monitor output mute whenever the channel is ON by
jumpering Pins 5 and 6 together.
Pin 7 - TB TO CR (control line; jumper to pin 10 to activate)
Again, if you are wiring a channel for a studio microphone you will want
that channel to be able to talk back to the control room (CR). By providing
a contact closure between Pins 7 and 10 (via a user-supplied momentary
"TB" switch located in the studio) the channel's pre-fader, pre-on/off signal
will appear on the console's CUE bus (and hence at the built-in cue speaker)
allowing the operator to hear it off-air. Note this same talkback signal will
also automatically interrupt the operator's headphone feed.
Pin 8 - REMOTE ON (momentary contact to pin 10 latches channel ON)
Used to turn a mic channel ON from another location (user-supplied
momentary contact switch required).
Pin 9 - REMOTE OFF (momentary contact to pin 10 latches channel OFF)
Used to turn a mic channel OFF from another location (user-supplied
momentary contact switch required).
Pin 10 - ON/OFF/TB COMMON
Used in conjunction with Pins 7, 8 and 9 for external control of channel.
Pin 11 - TALLY COMMON (return from remote tally indicator)
Pin 12 - ON TALLY (lights remote tally indicator)
In addition to its own built-in switch "lamp" (in reality a solid state LED
indicator) the channel's ON switch can also run a second tally indicator
(maximum draw 25 milliamps) typically located in a user-supplied studio
talent control panel ON switch. This second indicator lets studio talent
know when their microphone is live.
