Technical Features - PROEL R88L Instruction Manual

8. MIC LEVEL
Ten-position level control of the Local Microphone Input
9. Labels
The labels identifying the audio sources can be printed out by the user
10. JTAG Connector
Used for factory setup
11. RJ45 Communication Port
The RJ45 port is used to connect the control panel to MATRIX88, which also powers the panel if it is connected to the
Matrix by 50 m or less of CAT5 cable. Connect the MATRIX88 ZONE REMOTE CONTROL to this port. Each remote
control operates exclusively within the audio zone to which it is connected. For example: if you connect ZONE REMOTE
CONTROL 4 it will work only within Zone 4
Connection between a UTP CAT5 cable and an RJ45 connector to link a microphone station, according to the
