Call-Alert Tone-Level Control (1)
This feature must be disabled by turning the control fully
counterclockwise.
Option Switches (2)
The three option switches are set to the OFF position by the factory
and should not be changed.
Matrix Connector (3)
This eight-wire modular jack (RJ-45) provides an audio and data
communications link to the Matrix system.
Program-Input Connector (4)
A three-terminal, plug-on connector provides the program input to the
panel. Program is fed to the headset and speaker. The level to the
speaker or headset is controlled by the program-level control. The
program-input connector accepts a balanced or unbalanced line-level
audio signal from -20 dBu to +10 dBu. If this input is connected to the
stage announce (SA) output of a main panel it can be used as a paging
input. Since the level of this input is independently adjustable from the
intercom audio volume, it can be used to override the intercom audio.
