The VM-2240 is a multifunctional amplifier that can be mounted in an EIA-Standard equipment rack (3-unit size). The unit comes with 4 audio inputs including the background music input, and the speaker output section which has an internal attenuator and 5-zone selector. It permits not only general-purpose broadcast, but also Emergency Broadcast based on the EN 60849 Standard which gives pre-recorded voice instructions(*1) in the emergency situation. Broadcast can be made from an optional RM-200M Remote Microphone as well as from the amplifier, and can be remotely controlled from external equipment. In addition, for 100 V/83 Ω application the unit features the surveillance function(*2) which automatically checks the system for failures. (*1) An optional EV-200M Voice Announcement Board is required. (*2) An optional SV-200MA Surveillance Board is required.

Voice Announcement Board

The EV-200 is playback-only Voice Announcing board to play back the messages recorded on TOA's EV-350R.The EV-200 is designed to built in the VM-2000 series amplifiers.

Remote Microphone for VM-2000/VM-3000

RM-200M Remote Microphone for the VM-2000 and VM-3000 Series systems.

Remote Microphone Extension Unit

  • The RM-210 is an extension unit for increasing the number of function keys of TOA's RM-200M, RM-200XF and RM-200X Remote Microphones.
Surveillance Board

The SV-200MA Surveillance Board consists of an SV-200M board and an SV extension board to be used in combination. Installing the SV-200MA board inside the VM-2120 or VM-2240 amplifier adds the following functions to the VM amplifier's functions.


  • Permits monitoring of individual speaker line or power amplifier failures for status indication
  • Enables the VM amplifier to bypass external attenuators on individual zone calls
  • Backup amplifier function
  • Control inputs and outputs corresponding to individual zone selection status
  • A-1724

    A-1724 (240W)

    • The A-1700 Series of high-performance mixing-dedicated power amplifiers are ideal for PA applications that value versatility. Specifically designed to satisfy the multi-microphone public address requirements of environments such as places of worship and meeting halls, the A-1700 Series Microphone Mixing Amplifiers focus on operational flexibility as well as advanced functions, proving an ideal cost-effective PA solution.
