PM9-EOL
End-of-line device
- Compact device for loudspeaker end‑of‑line supervision
- Reliable solution for (long) loudspeaker lines
- Fault detection in amplifier without additional wiring
- Low level, high frequency pilot tone
- Flexible mounting options
This end‑of‑line device is a reliable solution for loudspeaker line integrity supervision, which is a requirement for emergency sound systems. It is connected at the end of a loudspeaker line, after the last loudspeaker of a series of looped-through loudspeakers.
It communicates with the PROMATRIX 9000 amplifier channel driving that loudspeaker line, to confirm the integrity of the line.
Where impedance measurements may not detect a disconnected loudspeaker, depending on the number of connected loudspeakers and cable type, or report false faults, the end-of-line device provides a superior solution to report the correct status of the loudspeaker line.
The enclosure size is compatible with the mounting provisions in most Dynacord loudspeakers for supervision boards or devices. It can also be reduced in size to fit most cable junction boxes.
