Introduction
L’ADA-1033 is an analogue audio distribution amplifier that
can be configured for monaural or stereo applications. In
single mode, it distributes one input to eight outputs and in
dual mode each channel has four outputs.
Each channel gain is trim controlled from the frame controller
or from an external remote potentiometer. All modules of the
DENSITE Series include a push button on the card front
edge, which permits to assign the front panel controller to
consultation and adjustments. A multi-coloured Led, visible
with the door closed, reports the card status
The ADA-1033 requires a 'single' or a ‘double' rear connector
panel.
