MUTING SYSTEM - The Amplifier is equipped with a noiseless,
fast acting Logic MUTING Switching System. When any of the
INPUTS are activated and a Signal is present on a given INPUT
and the VOX 1 is Switched-ON (using internal Jumpers) then the
MUTE 1 is ACTIVE. If any of the INPUTS have the MUTE 1
Switched-ON (by Internal Jumpers) then the INPUT (or INPUTS)
will be MUTED according to the Jumpers Setting. Once the SIG-
NAL-ON on the ACTIVE INPUT is terminated the normal functions
are automatically restored on all muted inputs.
