1.GENERAL DESCRIPTION
[VX-200SPANC]
• The VX-200SPANC is an audio signal output module of the VX-2000 system with speaker line pilot tone
detection. This module is to be mounted in the VX-2000SF Surveillance Frame and detects speaker line short
circuits, open circuits by monitoring for the presence of a pilot signal, and ground fault.
• The ANC Function automatically adjusts the amplifiers output volume in response to the change in ambient noise
level. The output volume changes as the ambient noise level goes above the set reference level.
2. HANDLING PRECAUTIONS
• Do not install the unit in locations exposed to the direct sunlight or heaters, as the unit could be deformed or
discolored.
• Avoid installing or storing the unit in dusty or humid locations, as doing otherwise could cause the unit's
failure.
• Keep the unit as far away as possible from a fluorescent lamp, digital equipment, PC or other equipment
which generate high frequency noise.
• Because each unit is not "hot-pluggable," the system needs to be shut down when it is installed or removed.
For turning the system power off, refer to the VX-2000 series Instruction manual, p. 3-11.

When the audio signal is fed from VX-2000SF AUDIO LINK IN, or the CTRL terminal is short-circuit, the
noise input from SENSOR is terminated. In this condition, correct adjustment is not available.
Adjust the sensor input level through monitoring ANC indicator. When the Sensor input level over

6. SPEAKER LINE FAILURE DETECTION METHODS
Note
The failure detection functions described here are designed to perform on a 100-volt line of speaker. For the
methods using a 70- or 50-volt line, please consult your TOA dealer.
The VX-200SPANC Pilot Tone Detection module detects speaker line failures by using a pilot tone. A 20kHz failure
detection pilot signal is superimposed on the signal line. To detect speaker line failures, the VX-200SPANC checks
the signal return from the speaker line end to the LINE MONITOR terminal.

7. Installing Module (VX-200SPANC) in the VX-2000SF Frame
Notes
• The slot number and module type to be installed must be identical to those designated by the PC software.
• Equate the VX-200SPANC as VX-200SP when setting them on the PC
software.
• Cover idle slots with the supplied blank panels to prevent dust from getting into the equipment.
Step 1. Align the module with the rails inside the VX-2000SF Frame, then push the module in to plug its
connector strip securely into the VX-2000SF's internal connector.
Step 2. Tighten both the top and bottom screws.
