VOX AND MUTE
- The Amplifier provides an independent VOX
and MUTE SYSTEM
FUNCTION SOCKETS
- EACH INPUT IS PROVIDED WITH A
VOX (V1) AND A MUTE (M1) SOCKET.
INPUTS VOX AND MUTE FUNCTION
- All Inputs provide a VOX
SEND and a MUTE RECEIVE functions. The VOX and MUTE
functions are SWITCHED-ON, on each Input, by Internal Jumpers
provided for each Input. The VOX BUSS SEND (V1) and the MUTE
BUSS RECEIVE (M1) can be independently SWITCHED-ON or
OFF to suit the application requirement.

JUMPER SETTINGS
- The VOX and MUTE Functions are
SWITCHED-ON or OFF by setting the JUMPERS on the VOX
(A)
and MUTE
(B)
SOCKET. See Fig. 8A.
The SOCKETS are located on the Main PCB inside the Amplifier
as shown on the SWITCHES and JUMPERS LOCATION DIA-
GRAM in this Manual. Each Socket is identified by an ID NUMBER
and the FUNCTION and DEFAULT settings are listed on the
FUNCTION SWITCHES and JUMPERS DEFAULT SETTING
TABLE in this Manual.
TO SET: Lift the Jumper and reset as required. making sure that
the JUMPER is properly positioned over the two shorting pins.
The VOX JUMPER has two positions:
OFF, and V1

The figure below shows how the VOX 1 Logic Switch is switched
ON and the MUTE 1 Logic Switch is SWITCHED-OFF by moving
the Jumpers as indicated. When the Input is activated by a Source
signal the corresponding VOX Signal is sent to the V1 BUSS.
When the VOX 1 is activated by any Input the MUTE Signal is
present on the MUTE 1 BUSS and it will MUTE any Input with the
MUTE M1 turned on.

IMPORTANT NOTE
BE SURE NOT TO SET BOTH THE VOX AND
CORRESPONDING MUTE ON THE SAME
INPUT OR THE INPUT WILL MUTE ITSELF
WHEN ACTIVATED.
EXAMPLE: INPUT 1 - V 1 and M 1 BOTH ON.
