RMI USER MANUAL

1.0 DESCRIPTIONS

RMI is a remote microphone input modular work together with RMI, which will be
used to input remote microphone. Two microphone inputs by XLR type connector are
included, while both of them are designed of bass and treble tone control, moreover,
master volume control of each microphone inputs are provided for dedicated control. A
remote mic VOX mute button is provided to override the background music system
when enabled. The communication between the panel and the matrix is through
universal industrial standard CAT5 cable, which also is used to supply power from the
matrix to this panel within 50 meters. There are total 8 units of remote control panels
could be work together with the matrix.
It will be very useful to be installed at a remote place which could be used to input
priority microphones.

3.0 CONNECTION & WIRING

3.1 Power supply. The RJ45 port is used to communicate between the remote
control panel and the matrix, it also will be used to power supply the panel
within 50 meters. While spare DC24V input is provided for extra power soupy
to the remote control as soon as the communication distance is longer than 50
meters. The communication cable shall be universal industrial CAT5 cable.

3.2 Microphone input. The mic input's 3 pins at the back side will be send to
the PCB board through the microphone signal input.

3.3 Aux output: Aux output is included in the Rj45 communication port, a spare
aux output is also provided.

3.4 SPARE AUX OUTPUT & SPARE 24V DC INPUT.

4.1 Power Supply. The remote control panel will be power on whether there is
DC24V from the matrix or extra equipments. The power indicator will be light
on blue, which also will be as status indicator to display the communication is
well or not.

4.2 Volume & Tone Control. A ten levels volume control is provided for each
microphone inputs, separate bass and treble tone control is also provided
