ADDRESSABLE VOX SYSTEM

VOX - VOICE ACTIVATED MUTING

- The Amplifier is

equipped with a noiseless, fast acting Logic VOX 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
BUSS 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 SIGNAL-ON on the ACTIVE INPUT is terminated
the normal functions are automatically restored on all muted
inputs.

ACCESS TO VOX AND MUTE JUMPERS

REFER TO JUMPERS AND SWITCHES INTERNAL
ACCESS.

CAUTION: PRIOR TO PERFORMING THE ABOVE OPER-
ATION BE SURE TO FOLLOW THE SAFETY NOTES
REFERRING TO THE REMOVAL OF THE AMPLIFIER
COVER.

OX SENSITIVITY ADJUSTMENT

1) Turn all Front Panel Input Level Controls to 0.
2) Turn VOX Sensitivity Control counterclockwise until it
stops.
3) Connect a Signal Source (Microphone, Telephone or
Music) to the respective Input Terminals (For connection
details refer to the appropriate section in this Manual).
4) While talking from a Paging Source (Microphone or
Telephone) or Playing Music rotate the INPUT LEVEL CON-
TROLS (Front Panel) until the desired output level is
achieved.
5) While talking from a Paging Source (Microphone or
Telephone) or Playing Music, turn the Sensitivity Control
(VOX 1) slowly clockwise until the Muting is activated.
