PROFESSIONAL AUDIO & SOUND ® DIGITAL MUSIC AMPLIFIERS FUNCTION SWITCHES AND JUMPERS UNDERSTANDING THE INPUT FUNCTIONS 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. SETTING THE VOX AND MUTE JUMPERS 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. VOX SEND V1 TO VOX BUSS The VOX JUMPER has two positions: The MUTE JUMPER has two positions: OFF, and V1 OFF, and M1 VOX JUMPERS SOCKET MUTE JUMPERS SOCKET SOURCE IN ANY INPUT AUDIO OUT SOCKET ID NO.

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.
