Operation
Switch on power to the receiver unit and check that the red power LED is lit on each channel (if not,
turn the VOLUME rotary control just past the zero point).
Move the switch on the first handheld or beltpack transmitter to the first notch (MUTE) – the LED (7)
should light momentarily and the RF indicator (4) on the receiver should light to show an active radio
carrier signal.
Move on another notch (Fully ON) and gradually increase the microphone level on the receiver, then
increase the volume on the mixer or amplifier until the sound from each microphone can be heard
through the equipment.
The AF indicator (5) on the receiver will flash with any sound made into the microphone.
Output level for each microphone can be adjusted using the rotary controls on the front panel of the
receiver unit.
Repeat for the other 5 microphones. (Note: if output is low from neckband microphones, it may be
necessary to adjust the Gain control (10) inside the beltpack unit).
The HU6 system uses specially developed filtering techniques to enable all 6 channels to operate
independently within the narrow license free UHF band. In order to do this successfully, there should
be a minimum distance of 2 metres between any of the transmitters and the receiver to help avoid
cross-interference of RF carrier signals.
During use, it may be useful for the reception of the microphone to be muted for a short period of
time (e.g. to avoid feedback when walking across the front of a speaker or avoid handling noise
when placing the microphone down momentarily or adjusting a neckband microphone).
In these circumstances, it may be better to move the transmitter switch to the “MUTE” position,
which maintains the radio frequency carrier signal but mutes the microphone input. When this switch
is moved back to the “ON” position, the sound will be immediately restored without waiting for the
radio signal to be reinstated.
If the wireless system is not to be used for more than a few seconds, it is preferable to slide the
transmitter switch to the “OFF” position, which mutes and deactivates the radio signal and powers
down the transmitter. Be sure to turn down the volume of the mixer or amplifier and then switch off
the receiver.
Unplug signal leads from the receiver and mixer or amplifier when moving or packing away.
If the system is not to be used for long periods of time, remove the batteries from the transmitters
and unplug the power adapter from the receiver and the mains outlet. Folding away or removing the
antennas can also help avoid damage when the system is not in use.
