(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.*

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).
