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.
