5.2. Operation During Monitoring
[VX-200SZ]
Because the VX-200SZ monitors speaker lines by comparing their impedance, when external attenuators are
used, they are bypassed to monitor the system. When connecting an external attenuator to the VX-200SZ, set
as "Use external attenuator" in the PC software, then set the monitoring time interval.
Monitoring time intervals and External Attenuator Control terminal operations differ depending on the operation
mode and whether or not external attenuators are used.

PC Setting : Impedance Monitoring Interval Setting

2
PC Setting : Monitor Interval in AC Failure Mode
Note
When external attenuators are used, they are bypassed at set monitoring time intervals, even during BGM
broadcasts.
[VX-200SP]
Because the VX-200SP monitors speaker lines by checking with a pilot tone, external attenuators need not be
bypassed during monitoring. In this case, the Attenuator Control terminals do not operate during monitoring.
The VX-200SP carries out monitoring at intervals that correspond to the operation mode. For details, refer to
the table below.
