AB-120 Announcer Console Instruction Manual
1 - 2
AB-120 can be used with virtually any broadcast headset or separate
microphone or headphone fitted with a Switchcraft™ or Switchcraft
style XLR-5M or 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 line. 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 IFM 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.
The AB-120 connects directly to a Clear-Com party-line 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 mute 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.
