TOA VM-2120 System Management Amplifier (ER Version)

฿36,500.00

The VM-2120 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 EN60849 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.
