MU16 / MU26 User Manual
Operation
For handheld transmitters, insert the supplied 2 x AA batteries by carefully unscrewing the base to
reveal the battery compartment inside the microphone body, slide the batteries into the
compartment (note: negative towards top of microphone) one behind the other and replace the
compartment cover. To switch the transmitter on, move the slide switch to the first notch (MUTE) –
the LCD backlight will illuminate – then move on another notch and the microphone will be switched
on, showing the frequency and battery status – the backlight will go out after a few seconds.
For beltpacks, squeeze down the clip in the centre of the front panel of the beltpack to unfasten the
lower half, which hinges outwards to reveal the battery compartment. Position the supplied 2 x AA
batteries inside ( and - are the correct way round for each) and then close the battery
compartment flap until clipped back into position. If using a neckband or lavalier microphone, ensure
that the sensitivity switch is set to the “mic” setting (the alternative setting is for use with
instruments via a jack lead and will be quieter). To activate the transmitter, press and hold the ON /
CHECK button (see diagram above) until the word “ON” is displayed – this is replaced by the
frequency and battery status. The backlight will go out after a few seconds, pressing the “ON /
CHECK” button momentarily switches the backlight on briefly.
Position the receiver within the best available line of sight to the transmitter(s) and connect the DC
jack of the supplied power adapter to the receiver and the plug-top to the mains outlet. Turn
microphone level(s) down on the receiver. Extend both antennae fully upwards and outwards slightly
and press and hold the POWER / IR SYNC. Button for more than 2 seconds – this will switch the unit
on.
Note: for dual sets (with 2 transmitters), both microphones’ outputs will be mixed and fed to both
balanced and unbalanced outputs.
Connect the jack or XLR (optional) lead to the receiver’s audio output connector, turn down the
volume of any equipment (mixer, amplifier etc.) that the signal will be fed into and then connect the
jack or XLR to the equipment.
Warning! - take care not to point microphones towards speakers – this can cause damaging feedback
(loud whistle or howling noise) – try to point microphones away from the speaker cabinets.
Tuning
The receiver LCD display shows the channel number (2 separate channel numbers on dual receivers)
and RF and AF level meters to indicate if Radio Frequency (RF) carrier is being received and if Audio
Frequency (AF) is being heard by the receiver.
To tune the transmitter(s) to the receiver, the receiver can send an Infra Red (IR) signal to the
transmitter – this is called “IR Sync.”.To activate this, select the desired channel using the Frequency
Up/Down buttons (see diagram above) and the channel number selected will show on the LCD
display. Briefly press (do not hold) the “POWER / IR SYNC” button on the receiver and the frequency
value will flash on the LCD display.
For handheld units, hold the transmitter with the IR sensor (either on the end or rear of the
microphone body) near to the IR sender on the UHF receiver unit (see diagram above). The display
