The VX3004F frame is one of three system managers of TOAs VX3000 series rackmount type public address and voice evacuation system certified according to the European Standard EN 5416. It provides 4 output channels for AB speaker lines, each channel driven by a separate amplifier module. The amplifier modules can be easily mounted and removed. Up to 4 power amplifier modules of different wattages can be mounted, one of which can be used either for one channel or as a standby amplifier. The standby amplifier, when mounted, can be shared among other VX3000F units. Each amplifier channel has the following DSP functions: different filter types (PEQ, HPF, LPF, shelving, CDhorn EQ, notch), compressor and delay that enables appropriate acoustic adjustment for any broadcast area. The smart ANC function enables the control of ambient noise and is not affected by the audio signal it controls. Therefore, the sensor’s installation location is not critical. The monitoring of the speaker lines can be selected between impedance monitoring with selectable pilot tone or by endofline modules. The VX3004F has 4 balanced audio input terminals from microphone up to line level sensitivity, with phantom power selection for microphone use. The inputs can also be set for receiving an emergency broadcast from another VA system of higher priority and broadcast it under the condition of the emergency mode. Up to 8 remote microphones can be connected via RJ45 ports; two of which can be emergency microphones. The following DSP functions are available for each input channel: different filter types (PEQ, HPF, LPF, shelving) and compressor. Helpful features such as feedback suppressor or voicecontrolled broadcast activation (VOX) enhance the usability of the system.
