1. Power amplifier link connector [PA LINK]
This rJ45 connector connects to the PA lINK
connector of the VP-200VX Power Amplifier Input
module or the VP-3000 series Power Amplifier.
Both lEDs on this connector are not used.
2. Run indicator [RUN]
flashes green when system equipment is operating
correctly.
3. Set indicator [SET]
Indicates system initialisation setting status.
• Off:
Initialisation undone (factory-set)
• Flashes green: Initialisation in progress
• Lights green: Initialisation completed
4. VX-200SZ plug-in screw connector
Signal lines to be connected are shown below:
• External attenuator control [ATT CTRL]
Permits connection of 4-wire system attenuators.
for the connection instructions, refer to
.
The attenuator bypass method can be changed
from relay to photocoupler type. for the
modification instructions, refer to
.
• Speaker output [SP OUT]
connects to the speaker.
• Power amplifier input [PA IN]
connects to the power amplifier's speaker
output.
5. Standby amplifier bus connector
[STANDBY PA BUS]
connects to all outputs of a single VX-2000Sf unit
to be switched over to the standby amplifier when
the power amplifier fails.
for details, refer to
,
for Standby
Amplifier connection.
6. VX-200SE mounting connector
used to mount the VX-200SE Equaliser card.
Install this module in the VX-2000Sf Surveillance frame to detect speaker line short circuits, open circuits by
comparing impedance readings, and ground fault.
Important Note
When combining this module with the VP-200VX BGm Input module, then the signal level applied to the VP-
200VX's external input should be low, i.e. about 10 dB below the rated level. The level can also be reduced by
the volume adjustment.
