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*

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*

which automatically checks the
system for failures.

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)
