2. GENERAL DESCRIPTION
[System Management Amplifier VM-2120/VM-2240]
Featuring outstanding audio performance, the TOA System Management Amplifier VM-2120/-2240 satisfies the growing need for reliable and efficient communications for various applications, especially for medium- sized facilities including office building, factories, hospitals, and transportation terminals.
The VM-2120 (120 W) and VM-2240 (240 W) are multifunctional amplifiers that can be mounted in an EIA- Standard equipment rack (3-unit size). Both units come with 4 audio inputs including the background music input, and the speaker output section which has an internal attenuator and 5-zone selector. They permit 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, both amplifiers feature the surveillance function*2 which automatically checks the system for failures.
*1 An optional EV-200 Voice Announcement Board is required. *2 An optional SV-200M Surveillance Board is required.
[Remote Microphone RM-200M]
The RM-200M is a dedicated unit for both the VM-2120 and VM-2240, and permits Emergency Broadcast as well as general-purpose broadcast.
[Remote Microphone Extension RM-210]
The RM-210 is an extension unit for the RM-200M's key operating section.
3. FEATURES
•Broadcasts of up to 480 W can be made to up to 10 zones individually or simultaneously. (when 2 VM-2240's are used).
•Permits monitoring of individual speaker line or power amplifier failures for status indication. (Requires the optional SV-200M Surveillance Board.)
•Reproduces 5 general-purpose messages, 1 chime tone, and 2 emergency messages. (Recordable as you like using the optional EV-200 Voice Announcement Board)
•Six different built-in chimes and prerecorded chime tones (by the EV-200) can be selected to attract attention to broadcasts.
•Backup battery maintains operation during power failures.
•Emergency broadcast based on the EN60849 Standard provides prerecorded voice instructions in the emergency situation.
•Emergency broadcast bypasses both the amplifier volume control and the external attenuator, making sure that the broadcast is heard throughout all zones.
•Features following broadcast priority levels: the highest level for Emergency broadcasts and 4 levels for general-purpose broadcasts.
•Speaker lines for 100 V line applications (standard) or for 50 V or 70 V line applications (enabled by changing the unit's internal wiring).
•Up to 4 remote microphones can be connected, and their total connection cables can be extended to 800 m. (RM-200M/-210)
•Speaker zones can be programmed into up to 5 groups for group broadcast.
(The remote microphone can broadcast to the Groups 1 and 2 out of the 5 groups.)
•Clear, distortion-free announcements owing to the internal compressor circuitry. (RM-200M/-210)
