43. BGM 1 & 2 Input Terminals [BGM 1, 2]
(VM-3240VA only)
Connect the BGM sound source.
(–10 dB*, 10 kΩ)
*
0 dB =1 V
44. Emergency Control Input Terminals 1 – 6
[EMERGENCY CONTROL, IN 1/IN 2]
Connect to an automatic fire alarm control panel.
Contact inputs 1 – 5 are no-voltage make contact
inputs.
Input 6 is an isolated voltage input which is
activated when the polarity of the applied voltage
(24 V DC is kept applied to this terminal under
normal condition) is reversed.
45. DS Link Connector [DS LINK]
Connects to the VX-2000DS Emergency Power
Supply’s DS-SF link connector.
46. Not used.
47. Audio Input Terminals 1 – 3 [INPUT 1 – 3]
(VM-3240VA only)
Electronically-balanced 600 Ω, –10 dB* / –50 dB,
XLR/phone jack combination connectors. LINE
or MIC input can be selected, and the phantom
power supply turned on and off. (Refer to "Inputs
1-3 Settings" on page 66.) These inputs can be
converted into transformer-balanced terminals
using the optional IT-450 transformer. It is also
possible to change microphone sensitivity to –30
dB. (Refer to the separate Installation guide.)
*
0 dB = 1 V
48. PA Link Connector [PA LINK]
Not used.
49. AC Input
Connects to an AC outlet using the supplied AC
power cord.
50. Attenuator Control Outputs [ATT CTRL]
Not used.

52. 22 V DC Output [22 V, +, –]
Provide 22 V DC output, max. 0.3 A.
53. Functional Ground Terminal
Noise may be generated when external
equipment is connected to the unit. Connecting
this terminal to the functional ground terminal of
the external equipment may reduce the noise.
Note: This ground is not for protective ground.
54. Control Output Terminals 1 – 8 [CTRL OUT 1
– 8, G]
Not used.
