SU20 User Manual
Setting Up
Insert the supplied AA batteries into the handheld transmitter by carefully unscrewing the base to reveal
the battery compartment inside the microphone body, connect the batteries ( and - are the
correct way around for each cell) and carefully screw the base back on.
For bodypack transmitters, gently pull downward at the inset on the front of the beltpack and flip forward
the front cover to reveal the battery compartment. Insert 2 x AA batteries ( and - are the correct
way around for each cell). 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 transmitter and connect the DC jack of
the supplied power adapter to the receiver and the plug-top to the mains outlet.
Connect the 2 UHF antennas to the BNC connector on the rear panel or alternatively, attach each to the
supplied rack mounting brackets, connecting via the BNC extension lead supplied.
Turn mic levels for CH. A and CH. B down on the receiver.
A choice of unbalanced 6.3mm jack or balanced XLR output is available on the rear panel of the receiver.
Connect the supplied 6.3mm jack lead for a mix of both channels or optionally, connect an XLR lead to
each balanced XLR output for 2 independent outputs.
Turn down the volume of any equipment (mixer, amplifier etc.) that the signal will be fed into and then
connect the jack lead or XLR leads to the equipment.
Warning! - take care not to point the microphones towards speakers
–
this can cause damaging feedback
(loud whistle or howling noise)
–
try to aim the microphone away from the speakers.
Operation
Switch on power to the receiver unit.
Move the switch on each handheld transmitter 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 mutes 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 the transmitter slide switch has a “MUTE” centre posit
ion, which is not used with the SU-
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 antenna can also help avoid damage when the system is not in use.
