System Function
Detailed block diagram
Configuration settings
- The system block diagram shows the many
configuration possibilities to satisfy the unique requirements of each installation.
The DIP switches are labeled with letters for easy identification and logging
using the configuration sheet provided at the rear of this guide.
Mic priority - When switched, all mics except mic 1 are turned off. Note that
mic 2 becomes the priority mic if mic 1 is configured for paging. In this case,
the paging mic 1 is not affected by the priority switch.
Music priority - If configured, the pre-level music 1 signal is detected. If it
exceeds a -20dB threshold the Z1 and Z2 FETs are turned off to mute the
currently selected music source. Release time can be set to short or long.
Paging - Overrides any page enabled zone by ducking the VCA by 20dB
when page signal is detected.
Remote control - The Zone remote may be custom wired to potentiometers
and switches or connected to the PL-12 wall plate using standard CAT5 cables
as shown here. Other functions may be hard wired to the Utility remote.
