1. SWITCHING OFF THE SYSTEM POWER

When it is necessary to open the equipment's case for modification or change of setting, the system's power
needs to be switched off.
If the DC power supply from the VM-3240VA/3360VA, VM-3240E/3360E, and VX-200PS to the VX-2000DS
stops, the VX-2000DS automatically switches the system's power supply over to the battery. The system
power can be switched off without switching over to the battery by using the VX-2000DS' Setting switch.

Note

Stopping the AC power supply to the VX-2000DS automatically switches the power supply over to the battery.
Take care not to stop the AC power supply to the VX-2000DS.

[To switch off the system power]

Step 1. Terminate all current broadcasts to stop system operation.

Step 2. Shift the Setting switch on the VX-2000DS's rear panel to the "AC" position.

Step 3. Stop the AC power supply to the VM-3240VA/3360VA, VM-3240E/3360E, and VX-200PS by

disconnecting each unit's AC power cord.
This permits the system power to be switched off without switching over to battery operation if AC
power is supplied to the VX-2000DS.

[To restore the power supply to the system]

Step 1. Restore the AC power supply to the VM-3240VA/3360VA, VM-3240E/3360E, and VX-200PS.

The DC power is supplied from these units to the VX-2000DS.

Step 2. Shift the Setting switch on the VX-2000DS rear panel back to the "DC" position.

Step 3. Operate the system normally.

2. INPUT TRANSFORMER INSTALLATION AND MIC INPUT SENSITIVITY
CHANGE

• Each of the MIC inputs 1 to 3 (electronically balanced) can be converted to a transformer-balanced input by

installing an optional input transformer IT-450 on the PC board.

• Each sensitivity of the MIC inputs 1 to 3 can be changed from –50 dB (factory-preset) to –30 dB by cutting

the corresponding jumper wire on the input PC board.

Step 1. Remove the screws securing the VM-3240VA/3360VA's cover (3 pieces on each side, 2 on the top,

and 1 on the rear) to detach the cover.

Step 2. Remove the input PC board.

The input PC board is fixed to the unit's rear panel with 8 screws.
Unscrew the PC board to detach it.

Step 3. To convert the electronically balanced input to a transformer-balanced one, install and solder the IT-

450 transformer at the corresponding location on the PC board.

Step 4. Cut the jumper wires designated according to purposes referring to the PC board diagram showing

the jumper wire locations below.

4-1. To convert the electronically balanced input to a transformer-balanced one

Cut the jumpers (a), (b), or (c) corresponding to the transformer-installed input on the pc board.

4.2. To change the microphone input sensitivity

Cut the jumper (d), (e), or (f) corresponding to the desired MIC input on the pc board.

Step 5. Replace the input PC board.

Step 6. Replace the cover.

3. VP-200VX INSTALLATION IN THE VP-2241/2421 AND
GROUND LIFT SETTING

3.1. Installing the VP-200VX in the VP-2241/2421

Step 1. Remove the VP-2241/2421 power amplifier's top panel.

Step 2. Unscrew the VP-200VX's panel to detach it.

Step 3. Mount the VP-200VX module.

Attach the VP-200VX's panel to the mounting location and the VP-200VX unit to the back of the
mounting location, then secure them to the amplifier using the screws removed in step 2.

Note: Mount the VP-200VX with its circuit board components faced down.
