Connection:
1. Connect the cable, one end to the balanced or unbalanced output jack of the receiver, the other end to the mic mixing
input of amplifier, audio mixer etc.
2. For best results set the output volume control at about three quarter level and adjust mixer / amplifier level to suit.
3. The squelch level is adjustable by the rotary pot at the back of the unit. Adjust the squelch level to prevent
external noise. Note: setting the squelch high (towards max) will reduce the range of the system.
4. When the receiver is not in use disconnect from the mains power.
IMPORTANT NOTE:
Never use the balanced and unbalanced outputs at the same time.
This may cause signal loss or increased noise.
1. Antenna Input Connector:
BNC-type connectors provide connection to the supplied antennas or to coaxial cable
used with an antenna divider, antenna boosters or remote antennas.
2. Balanced Output:
3-pin XLR connector provides balanced low-impedance output.
3. Unbalanced Output:
Unbalanced 6.3mm mono jack audio output for connecting to a line point.
4. Mic/Line Switch:
Use this to adjust output (XLR balanced connector and 6.35mm unbalanced phone jack) for
microphone (-20dB) or line-level (0dB).
5. Squelch:
Use the squelch to adjust the output level to suppress noise. The higher the squelch control, the lower the
sensitivity of the receiver and smaller the service area of the system. Set the squelch to minimum before turning
the receiver on. If you have unwanted noise increase the squelch control until the noise disappears.
6. DC IN:
DC Input connector for the included 12V DC power supply.
