NU20 User Manual
Setting Up
Insert the supplied AA batteries into the handheld transmitters by carefully unscrewing the base to
reveal the battery compartment inside the microphone body, connect the batteries ( and -
are the correct way round for each cell) and carefully screw the base back on. For bodypack
transmitters, squeeze and flip forward the front cover to reveal the battery compartment and insert
AA batteries, observing correct polarity. Connect the 3.5mm jack connector from the neckband or
lavalier microphone to the input on top of the bodypack transmitter and rotate to secure the thread.
Position the receiver within the best available line of sight to the transmitters and connect the DC
jack of the supplied power adapter to the receiver and the plug-top to the mains outlet.
Connect both antennas to the BNC connectors on the rear panel or alternatively, attach to the rack
ears, connecting via the BNC extension leads supplied. Turn mic levels down on the receiver.
A choice of mixed output of both microphones on 6.3mm jack or individual balanced XLR outputs is
available on the rear panel of the receiver. Connect jack or XLR (optional) leads to the relative output
connector(s), turn down the volume of any equipment (mixer, amplifier etc.) that the signal will be
fed into and then connect the jack or XLRs to the equipment.
Warning! - take care not to point microphones towards speakers
–
this can cause damaging feedback
(loud whistle or howling noise)
–
try to aim microphones away from the speaker cabinets.
Operation
Switch on power to the receiver unit.
Move the switch on the handheld transmitter(s) to the fully up position (ON) and gradually increase
the microphone level on the receiver (for bodypack transmitters, move the top
slide switch to “ON”)
,
then increase the volume on the mixer or amplifier until the sound from each microphone can be
heard through the equipment.
Note: if output is low from the neckband or lavalier microphone, it may be necessary to adjust Gain
control inside the bodypack unit
After use,
slide the transmitter switch to the “OFF” position, which mute
s and deactivates the radio
signal and powers down the transmitter. Turn down the volume of the mixer or amp and then switch
off the receiver.
Please note
that each transmitter slide switch has a “MUTE” centre position, which is not used with
the NU-series system. Switching the transmitter off automatically mutes the reception channel.
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.
