Controls

Front  Panel:  Individual  push  button  switches  for  each  input

channel  toggle  on  and  off  so  that  channels  may  be  monitored  in

any combination. An LED indicator illuminates when the corresponding

independently of the front panel VU bargraph meter. A push-button switch

with corresponding LED switches monitoring between the Processor and

Amplifier inputs. A 12-segment bargraph VU Meter indicates the input level

from -40 to +3 VU.

Rear  Panel:

  Three  trimpots  adjust  the  processor,  amplifier  and

VU meter input levels.

Power Requirements

100-300VAC, 50-60Hz, 32 Watts
