Multi-channel Wireless System
REAR PANEL DESCRIPTION
SERIAL/FREQUENCY LABEL
- This label indicates the serial number of the distribution module. It also indicates the
RF pass-band of the unit. IMPORTANT - The receivers installed in the unit must fall between the frequencies indicat
ed on the label. Serious signal loss results if the receivers are outside the RF pass-band.
POWER XLR CONNECTOR
- This 4 pin Switchcraft D4M connector is the power input jack for both the AC charger
and for external 12VDC power. Pins 1 and 4 are used for 12 VDC input. Pins 2 and 3 are utilized for 14 to 20 VAC
charging voltage.
POLARITY DIAGRAM
- The polarity diagram on the lower panel indicates the wiring connections for the 4 pin XLR
power connector. Use this diagram when connecting your own external power source to the system.
9V ALKALINE BATTERY COMPARTMENT
- The distribution module/s can operate from an internal 9V alkaline bat
tery. Only alkaline or lithium batteries are recommended. Poor results may be expected with other battery types. This
compartment opens by pressing in and to the right. The compartment will adjust to various battery sizes.
POWER LEADS
- These connectors provide power for the individual receivers. Insert the connectors into the jack
provided on each receiver.
INSTALLATION SCREWS
- The two large counter-sunk phillips head screws in the central area between the receiv
ers are used for receiver installation and removable. See the following page for further instructions.
RECEIVER AUDIO OUTPUT
- Supplies a balanced, low impedance output at microphone level. The audio signal
is output on pins 2 and 3, while pin 1 is ground. The output level of this jack is controlled by the OUTPUT control on
the front panel of the receiver and by the range switches in the battery compartments of the receivers (see receiver
instruction manuals). The connector is a standard XLR type.
RECEIVER POWER IN JACK
- Connects to the POWER LEAD for powering the receiver from the PRO 4 mini source.
A diode bridge is used in the external power input, so that the receiver will operate properly from either polarity.
