General
The IRT AAA-3131 is a
high performance audio distribution amplifier. Its features allow
standardisation on one ADA type to perform many functions with
consequent overall cost savings.
The AAA-3131 can be used
for either mono or stereo signals. It may be connected in balanced or
unbalanced configurations for either inputs or outputs, making it ideal
for duplicating applications.
Front panel access is
provided for the gain adjustment of Left and Right channels from zero
output to the maximum of the selected gain range.
LED's on the front panel
indicate the presence of audio on each channel and balanced
output bantam jacks are provided for front panel monitoring.
Optional plug in
sub-boards may be fitted to suit special applications:
AAO-3130:
FACTS stereo
oscillator module. Left continuous & right interrupted with remote
ADA/oscillator control switching.
CAA-3130: Remote
select Stereo/L+R / Lmono / Rmono and L-phase reversal control
module.
CAA-3132:
Remote L&R gain,
balance, stereo/mono and phase control module
The AAA-3131 is
fabricated in IRT's standard Eurocard format and may be housed in a
variety of IRT Eurocard frames alongside other standard modules.
