Introduction
Thank you for choosing the U-MIC for your wireless microphone requirements.
This system is designed to provide a reliable, cable-free solution with minimal
setup and ease of use. Please read and keep this user manual to get the best
results from your product and avoid damage through misuse.
Layout
Setting up
The U-MIC is supplied as 2 individual beltpack microphone transmitters and a USB
receiver with a 3.5mm to 6.3mm jack lead.
The USB type A plug (6) on the receiver should be connected to a USB port for
power (5V, 1000mA). This can be from a USB power adaptor or power bank for
portable use if required. The connection can also be made to the receiver using
an optional USB extension lead if preferred.
Note: the audio is not transmitted to the USB port. The USB is for power only.
If the USB port is a U-Disk player or computer port, the digital media (USB stick)
or other peripheral device can still be connected through the receiver by
connecting to the USB type A socket (8) on the rear of the receiver.

Operation
The U-MIC receiver is designed to connect to a microphone input jack on a mixer
or amplifier. Turn down the volume level on the microphone input of the mixer or
amplifier before connecting to avoid loud noises when connecting.
Connect the 3.5mm plug of the supplied lead into the USB receiver (7) and
connect the 6.3mm plug to the appropriate microphone input jack on the mixer
or amplifier.
Note: The output of both of the beltpack transmitters is mixed to the same single
3.5mm output.
Each beltpack transmitter has an on/off switch (4), which should be in the up
position (off). The top volume control (1) should be turned fully down. Connect
the neckband microphone to the 3.5mm microphone input (2).
Slide open the cover of the battery compartment (5) and insert 2 x AA alkaline
batteries per transmitter, ensuring that the polarity is the correct way around.
Move the switch down to the “on” position and the power indicator (3) should
light. Note that the switch has a centre position which is also “on”.
Gradually turn up the volume control on top of each beltpack transmitter and the
level on the mixer or amplifier and speak into the neckband microphones in turn
until the sound can be heard through the connected speakers or recording
equipment. Increase the volume to the required level.
If the microphones are not being used, turn down the volume level on the top of
each beltpack transmitter and the mixer/amplifier and switch the power off.
For long term storage, unplug the jack and USB receiver and remove the
batteries from both beltpack transmitters.
