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.

internal connector wiring as shown below.
Note
The speaker line failure detection functions are designed to perform on a 100-volt line of speaker. Set these
functions to OFF if the amplifier’s speaker line voltage is set to 50 V or 70 V. For the methods using a 70- or
50-volt line, please consult your TOA dealer.
Step 1. Remove the top cover referring to p. 3, step 1.
Step 2. Pull the cable connector (9-pin) connected to CN182
connector on the circuit board with the output attenuators.
Step 3. Change wires inserted into the cable connector for different
wires according to color-coding shown in the table below to
switch to the desired line voltage.
Step 4. Connect the cable connector to the circuit board.
Step 5. Replace the top cover.

6. CONNECTING TO THE SX-2000 SYSTEM
Note
This function can be used only when all the versions of VM-3240VA/3360VA firmware, VM-3240E
/3360E firmware, and VM-3000 Setting Software are 2.00 or later and SX-2000 system ver. 3.00 or later.
6.1. General Description
Additionally connecting the VM-3240VAs/3360VAs to the SX-2000 system allows the SX-2000 system's
speaker line capacity to increase by 6 speaker lines per a single VM-3240VA/3360VA. In this case, the entire
system operates as shown below.
• The VM-3240VAs/3360VAs perform only 1-channel broadcasting (no standby amplifier).
• The SX-2000 checks for the VM-3240VA/3360VA amplifier failure, and the line failure between VM-
3240VA/3360VA amplifier and the SX-2000 amplifier.
• The VM-3240VA/3360VA checks for the speaker line failure.
Besides, adding the VP-2241 or VP-2421 amplifier to the SX-2000 system as a standby amplifier maintains
the general-purpose broadcast operation even if the VM-3240VA/3360VA fails.
Notes
• The VM-3240E/3360E cannot be used in this system.
• In the system where the VM-3240VA/3360VA and the SX-2000 system are combined, the VM-
3240VA/3360VA cannot be used as Emergency broadcast equipment.
• Never place the VM-3240VA/3360VA in emergency mode nor operate emergency EV, RM-300MF, and front
emergency microphone to prevent the entire system from malfunction.
• Audio Input 4 is reserved. (See the table of VM-3000 Settings.)

6.2. VP-200VX Installation in the VM-3240VA/3360VA
Step 1. Remove the screws securing the VM-3240VA's/3360VA's cover (3 pieces on each side, 2 on the top,
and 1 on the rear) to detach the cover. (Refer to p. 3.)
Step 2. Make an opening for mounting the PA LINK connector by removing the
knockout plate on the VM-3240VA's/3360VA's rear.
Step 3. Remove 2 screws on the VP-200VX's front panel to detach it. (This removed panel is not used.)
Install the VP-200VX (without the front panel) inside the VM-3240VA/3360VA, then secure it with the
removed screws.

6.4. Operating the Combined System of the VM-3240VA/3360VA and
the SX-2000 System
Note
For installation, check the SX-2000 and VM-3000 settings by referring to the tables on p. 11.
Step 1. Power up or restart the VM-3240VA/3360VA after installing the VP-200VX in it.
Then, the VM-3240VA/3360VA recognizes the VP-200VX, making the VM-3240VA's/3360VA's
general control input terminal No. 8 have a function to shut off all audio signals input to the VM-
3240VA/3360VA when this terminal receives the control signal.
Step 2. Perform the general control input No. 8 setting on the VM-3000 Setting Software screen as shown
below. (For details, refer to the separate VM-3000 software instruction manual.)
Step 3. Apply a control signal to the VM-3240VA's/3360VA's general control input terminal No. 8.
Then, audio signals input to the VM-3240VA/3360VA are all shut off.

15
Step 4. Perform broadcasts from the SX-2000 system.
Audio signals input to the SX-2000 system enter the VM-3240VA/3360VA, return to the SX-2100AO,
and enter the VM-3240VA/3360VA again, and are finally output from the VM-3240VA's/3360VA's SP
OUT terminal. (Refer to the diagram below.)
[Audio signal flow when the VM-3240VA/3360VA is connected to the SX-2000 system]
Audio sources being previously broadcast are shut off by a control signal from the SX-2100AO. Instead, audio
signals entering the VM-3240VA/3360VA from the SX-2100AO are broadcast.
6.5. Example When the VM-3240VA/3360VA Connected to the SX-2000 System Fails
If the VM-3240VA/3360VA fails, audio signals from the SX-2100AO being previously broadcast are shut off.
Instead, another audio signals from the SX-2100AO are broadcast by the standby amplifier.
