AB-120 Announcer Console
XLR-6M connector. Microphone gain is jumper selectable to accommodate all microphone
types. The microphone output stage uses a high grade transformer for driving the microphone
output. Output levels from 0 dB to -50 dB are jumper selectable.
A high output stereo headphone amplifier provides talent with both program audio and cues
from the control room, even in the most noisy environments. The console can be configured so
that intercom audio and IFB inputs can be heard in the left/right ear or both, helping the talent
to instantly identify the source. The unit accepts one or two channels of IFB, which can be
standard self powered, three pin circuits like those found on most broadcast IFB systems.

Operation
Instant access to an intercom system is available with a talkback button. If the talkback button
is pressed, the microphone is momentarily switched from on air to intercom use. The
Announcer Console can be connected to virtually any party-line intercom system.
A mute button provides momentary silencing of the microphone. Alternately, it can be set to
latch when pressed, allowing the talent to switch the microphone on and off with a single
switch. The switch is mechanically and electrically designed to ensure no clicking or switching
noise is heard when pressed.
The AB-120 plugs into and draws power directly from most intercom and IFB systems,
permitting an announce position to be located virtually anywhere, regardless of AC power.
When a powered intercom or IFB is not available, the console can be externally powered with
the supplied DC adapter.
