The VX-3004F is a 4-zone AB loudspeaker controller in TOA’s VX-3000 series of voice evacuation systems. The device complies with the European EN54 standard for fire alarm systems. The device is equipped with audio inputs and can be directly connected to speaker outputs when used with amplifier modules. The device can also be set to broadcast a warning message with a higher priority than the normal warning level. Two emergency states can be activated at the same time (Fire zone evacuates, neighboring zones issue warnings). With the network connection feature, the system can be distributed.

The device includes the following features: Digital processing function allows to adjust the sound of each separate input and each output zone, anti-feedback function helps to reduce howling in the PA system, VOX is a function that allows START/STOP through the input audio signal, ANC function allows to adjust the system sound according to the environmental noise. (ANC function can distinguish the output sound of the device and the surrounding noise. The output sound of the device is not considered noise). The indicator light shows the error status and the status of each amplifier on the integrator.

The device has 4 outputs available, with one output providing both A and B ports for connecting to speaker wires. Supports up to 4 Power Amplifier Modules mounted in the integrator. With 4 amplifier channels, we can use them as 4 separate speaker outputs or use 3 separate speaker outputs and 1 as a spare. The VX-3004F is equipped with input and output ports for backup amplifiers, so the device can easily share backup amplifiers with other VX-3000F sets.
