3-11) CUE SYSTEM
The 1200 handles CUE two ways:
1)
AUTOCUE
feeds cue audio into the right side of the
monitor system while ducking the program audio.
2) &/or connect the mono CUE Output to an external cue amp.
a) Mono Cue Output -
the Cue output on PIN 7 of connector CN-5 is a mono mix of a stereo cue feed. Output
level is about +4dBu and low impedance
to drive
an external power amp and speaker. This output will mute when
the console muting bus is activated by an open MIC (the MIC channel‘s MUTE JUMPER
must be in place)
b) How to disable
AUTOCUE
- Cutting a wire jumper (shown below) will defeat AUTOCUE’S DIM feature. Cutting
the two resistors indicated defeats the
audio feed into the monitor/earphones.
3-12) TALKBACK SYSTEM
The 1200 features a talkback input to the
monitor-cue system. Audio (typically
from
another studio) fed to the talkback input
appear on the right earphone and
will
monitor
speakers, as well as the CUE output. The
DIM LOGIC feature
allows you to duck the
monitor program audio‘s level so that the
talkback
rides over the program audio.
a) TB AUDIO IN
An unbalanced talkback
audio input is on Pin 9 of CN-5. The input
gain stage
has a gain of 10 for low level
signals. Add an external series resistor of
value 10k ohm - 100k ohm to reduce the level to
match your talkback
audio feed.
b) TALKBACK SWITCH & LAMP
may be
wired for any purpose.
c) DIM LOGIC IN
a ground on Pin 6 of CN -
headphones by approximately 20dB.
3-13) ON-AIR RELAY
Pins 5 & 8 on CN-5
are the two poles of a reed relay that will
close when the
muting bus is active
(typically when a MIC channel is open).
Maximum
current is 50 milliamps
which can
drive an external relay for on air lights, etc.
