The V-9999 provides end of line termination of audio and 24 V dc
pairs when wire monitoring self-amplified
speaker runs. Compatible with the Supervised IDF models VL-9998RM (rack mount) and VL-9998WM (wall
mount), it monitors the power voltage and provides an equivalent impedance of 4.7k Ohm termination for
monitoring the audio pair. Should the power pair voltage drop below 10V dc, it will open the connection to the
audio pair terminating impedance causing the monitoring IDF to show a fault on the speaker run.
