2.5.3 Matrix Connector (3)
This eight-wire modular jack (RJ-45) provides an audio and data communications
link to the Matrix system.
2.5.4 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.
Note: The Program Input can be set between -20 dBu to +10 dBu.
The pinout of this connector is as follows:
