Instructions

Audio output connection

There are two kinds of audio outputs on the back of the receiver:



Balanced output of channel 1~4: Low-impedance MIC level.



Unbalanced output of channel 1~4 (mixed): High-impedance LINE level / Low-impedance MIC

level. Switchable between MIC and LINE levels.

Use shielded audio cable for the connection between the receiver and the amplifier/mixer. If the

amplifier/mixer has a 1/4"(6.3mm) phone jack, connect a cable from the 1/4"(6.3mm)

unbalanced audio output from the receiver to the amplifier/mixer. If the amplifier/mixer has an

XLR input, connect a cable from the balanced XLR audio output from the receiver to the

amplifier/mixer input.

Rack mounting

QR-4000N is an EIA standard 1U rack-mountable receiver base with metal chassis. It can be

cabinet-mounted with provided kits. Please refer to the following assembly illustration.

Receiver installation

For best operation, the receiver should be at least 1m above the

ground and 1m away from a wall or metal surface to minimize

reflections. The transmitter should also be at least 1m away from a wall

or metal surface to minimize reflections. The transmitter should also be

at least 1m away from the receiver. Keep antennas away from noise

source such as motors, automobiles, neon light as well as large metal

objects.
