TOA Electronics VM-2120 Function switch Settings An 8-bit DIP switch and selects, DC power input

Page 10

(2)Control input for broadcast activation [CTRL IN 1, 2, 3]

3 no-voltage make contact inputs, open voltage: 3.3 V DC, short-circuit current: under 1 mA

(3)24 V DC Power output [24 V OUT]

Supplies the 24 V DC/0.2 A power to an optional Amplifier Control Unit RU-2001/-2002.

29.Function switch [SETTINGS] An 8-bit DIP switch and selects

(1)Phantom power on-off for each input 1 – 3

(2)Telephone paging chime on-off

(3)7 different types of chime tones [2-tone chime/2- tone chime (fast repeat)/4-tone chime (Up)/Single- tone chime/4-tone chime (Up & Down)/Gong, and Pre-recorded chime*4], or chime-off

(4)MIC/LINE gain for inputs 1 – 3

Refer to page 48 "FUNCTION SWITCH OPERATION" for operation of the function switch.

30.Control input and output connector [CONTROL I/O]

A 25-pin, female D-sub connector.

(1)External control input

The following functions can be activated from external equipment.

• Message for an optional Voice Announcement Board

• Chime

• Power

• Emergency Broadcast

• Unit's broadcast cutoff

(2)Status output

When the unit is placed in the following status, the corresponding output is at make.

• Irregularity of communications with the Remote Microphone and an expansion amplifier.

• AC power ON

• DC power ON

• Irregularity of the sound source of the Voice Announcement Board.

• Failure (FAULT) indication on

• Power switch on

31.Attenuator control, external speaker input, speaker output connector

[ATTENUATOR CONTROL, EXTERNAL SP INPUT, DIRECT OUT, ZONE 1 – 5]

A dedicated, 16-pin plug-in screw connector and has the following input and outputs.

(1)External attenuator control output

[ATTENUATOR CONTROL]

An output terminal for bypassing the external attenuator.

(2)External speaker line Input

[EXTERNAL SP INPUT]

Accepts the signal from the external amplifier's speaker line. When the unit's broadcast cutoff input terminal of the Control Input and Output Connector (No. 30) is activated by an emergency equipment, the unit's power amplifier output is cut off, allowing the external signal to go through to the speakers in all zones.

(3)Direct speaker line output [DIRECT OUT] Outputs the signal directly from the power amplifier transformer output.*5 The volume level is the same as that which can be provided when the Zone Volume Control (No. 10) is set to the maximum position.

(4)Speaker output [SP OUT, ZONE 1 – 5] Connects to the speaker lines. This output is of 100 V line type, but can be converted to the 50 V or 70 V line type by internal connection change.

32.24 V DC power input

Connect the backup battery (maximum 24 V DC/7.5 A for VM-2120, 15 A for VM-2240) to this terminal.

33.AC inlet [AC mains]

Connect the supplied power cord to this inlet.

34.Fuse holder

The following miniature fuses (20 mm type) are used.

6.3 A (for 120 V AC version)

T2.5 A of time lag type (for VM-2120 230 V AC version), T3.15 A of time lag type (for VM-2240 230 V AC version)

Note: When the fuse is blown off, first remove the cause, then replace with the correct type specified on the unit.

35.Signal earth terminal

Note this terminal is not a safety earth. When there is hum noise, connecting this terminal to the body of connected equipment (BGM sound source, expansion amplifier, etc.) may reduce it.

*1 0 dB = 1 V

*2 Can be transformer-balanced with the addition of an optional IT-450 input transformer.

*3 Both the VM-2120 and the VM-2240 can also be combined.

*4 The chime sound source must be pre- recorded into a CF (CompactFlash) card to be inserted into the optional EV-200 Voice Announcement Board. (See p. 11.)

*5 Output signal source is switched to the EXTERNAL SP INPUT if the unit's broadcast cutoff is activated. See No. 31 (2).
