GENERAL DESCRIPTION

The TOA System Management Amplifiers VM-2120 and VM-2240 are expressly designed to fulfill increasing requirements for reliable and efficient communications in mid-size facilities such as office buildings, factories, hospitals, transportation terminals and many other sites. Both amplifiers are multifunctional designs, with the VM-2120 rated at 120W and the VM-2240 at 240W. Each amplifier may be cascade-configured to meet increased power demands. Conforming to EIA standards both amplifiers may be rack­mounted, taking up just a 3-unit space.
A VM-2000 Series amplifier accepts six audio inputs which include two BGM inputs and a telephone paging input. Speaker output selector for five zones is provided as well as an internal speaker attenuator. In addition to general­purpose broadcasts, EN60849* standard-based emergency broadcasts which may be pre-recorded* Microphone are possible. These operations can also be remotely controlled using external auxiliary equipment.

FEATURES

Features
●
A VM-2000 Series amplifier can be combined to increase its system coverage number of speaker zones.
●
Use of the optional SV-200M Surveillance Board allows system-wide integrity to be conveniently monitored such as CPU-initiated automatic checking at pre-set times for open or shorted speaker lines, any speaker circuit ground leaks as well as power amp section malfunctions. Signals can be sent to a status display which simplifies maintenance and instantly calls attention to faults.
●
If the EV-200 Voice Announcement Board is used, five general-purpose messages and two emergency messages as well as a chime tone can be output. To record customized announcements and messages, the optional EV-350R Digital Announcer can be used. In addition, this allows adding a customized chime tone to the six built-in chime tones.
●
When a VM-2000 Series amplifier is used in combination with an emergency power supply unit*, a backup battery ensures uninterrupted operation during power outages.
* TOA DS-1000B or similar emergency power supply unit.
●
During emergency situations a VM-2000 Series amplifier can provide phased emergency broadcasts as per EN60849* standard.
●
Emergency broadcasts preempt system volume settings as well any external attenuators to ensure the broadcast is easily heard in any speaker zone.
●
Four priority levels can be set for general broadcasts. All priority levels of general broadcasts are overridden in an emergency situation while emergency broadcasts are supplied to all zones.
●
Standard speaker line distribution is rated for 100V applications. 50V or 70V speaker line distribution can also be selected by an easily performed internal wiring change.
●
The system will accept up to four remote microphones (RM-200M) that can be extended totally up to a maximum of 800 meters.
●
The independent speaker zones may be programmed into a maximum of five groups to receive group broadcasts. If a remote microphone is used, it can broadcast to Group 1 and Group 2.
●
The RM-200M remote microphone provides announcements with extraordinary clarity and freedom from distortion thanks to a high­performance built-in compression circuit.

GENERAL PURPOSE BROADCAST INPUT

Input 1-3 (MIC/LINE)

Inputs 1 – 3 can be set for a microphone signal input level ( –60 dB, 600 Ω) or a line signal input level ( –10 dB, 600 Ω) by moving the SETTINGS switch in Fig. 1 to the ON or OFF position. The three inputs also feature Neutrik connectors that permit connection to XLR connectors and phone plugs. Furthermore, Input 1 can also be used for DIN plugs as well.
Equipment that can be connected to these input includes:
• Dynamic microphones
• Paging microphones
• Wireless tuners
• Background music players

BGM Inputs

Two background music inputs (BGM INPUTS: RCA pin jack, - 20 dB, 10 kΩ) are provided. An attenuator is also provided for each BGM input to adjust the sound volume when different sound sources are connected.
Equipment that can be connected to these input includes:
• Cassette players

GENERAL PURPOSE BROADCAST INPUT
External Connection Terminal
(Telephone Device Input)
A specified telephone paging number must be preprogrammed into the telephone exchange. The VM amplifier's power can then be switched on remotely by dialing this number from a telephone set, permitting telephone paging to be made from that telephone. Telephone paging zones can be set when programming the VM amplifier's zone groups. The telephone exchange's audio signal volume can also be adjusted.
NOTE: Please refer to Section 24 of the Instruction Manual for the zone group setting.

GENERAL PURPOSE BROADCAST INPUT
External Connection Terminal
(VS-900)
Use of the VS-900 in conjunction with the VM amplifier permits broadcasts to be made from each station connected to the VS-900. Configure the connections so that two control signals are transmitted from the VS-900 to the VM amplifier's CTRL IN 1 and CTRL IN 2 terminals, then assign different zone groups to the two terminals. This enables each station to make broadcasts to the set zone group.
Example
In the VM amplifier group settings, assign Zones 1, 2, and 3 to Group 1, and Zones 4 and 5 to Group 2. Set the VS-900 to output an activation signal from CONTROL 1 when broadcasts are made from the RS-150, and to output an activation signal from CONTROL 2 when broadcasts are made from the RS-160. By setting the VM amplifier and VS-900 in this way, broadcasts can be made to Zones 1, 2, and 3 from the RS-150, and to Zones 4 and 5 from the RS-160.

Control I/O (Timer)

By combining the VM amplifier with a timer, a chime tone can be broadcast at preset times.
Pattern 1
Program Timer TT-104B
Connect the timer (designed to deliver a no-voltage "make" contact output) to Pins 11 and 16 of the VM amplifier's control I/O terminal. The timer will then activate the VM amplifier at preset times to broadcast its built-in Westminster chime.
Pattern 2
Program Timer TT-104B
Install a pre-recorded memory card in the EV-200, then connect the timer (designed to deliver a no-voltage make contact output) to pins 3 – 7 and 16 of the VM amplifier's control I/O terminal. The timer will then activate the VM amplifier at preset times, and each of the recorded memory card messages will be played back whenever the VM amplifier is activated.
