BCD AUTOMATIC PRE-AMPLIFIERS - ALT
Microprocessor controlled microphone and line amplifiers with automatic gain control,
designed for use in situations where technically skilled staff may not be available to set
levels, such as remote contribution studios and workstations, or where automatic gain
setting offers operational advantages such as with camera-sited microphones or
talkback systems. Three models are now offered, one with simple remote control and
another with a switchable headphone amplifier or balanced to unbalanced converter
circuit.
