This optional module includes the independent functions for Control Room
Talkback to several locations, the Producer and External Talk interfacing, a 30
Hz slate tone generator and a test tone oscillator.
•
The OUTPUT buttons assign the test tone and the slate tone generators to any
combination of the Program (PGM), Audition (AUD) and Utility (UTL)
output buses.
•
The recessed GAIN TRIM controls independetly set these levels:
EXTERNAL OUTPUT sets the level of the External Talkback Output.
EXTERNAL INPUT sets the level of the External Talkback Input.
PRODUCER MIC sets the gain of the Producer Input preamplifier.
CONSOLE MIC sets the gain of the meter panel electret microphone.
SLATE LEVEL sets the output level of the slate tone. This control is factory-
set for a -6 VU meter reading.
•
The FREQUENCY selector and MULTIPLIER buttons set the output
frequency of the built-in test tone oscillator.
•
LEVEL adjusts the output level of the test tone oscillator.
•
OSC, when engaged (down), switches the test tone oscillator output to the
buses selected by the OUTPUT assignment buttons. OSC, when not engaged
(up) switches the Slate tone output to the buses adn turns off the tone
oscillator.
•
Pressing SLATE sends a mix of the 30 Hz Slate tone and the console
Talkback microphone to the buses selected by the OUTPUT assignment
buttons.
•
The three Talkback buttons (STUDIO 1, STUDIO 2, EXT) provide commu-
nications to two Studios and an External location. Multiple buttons can be
pressed for simultaneous communications.
