U-MIC DUAL User Manual
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 handheld microphone transmitters and a
USB receiver with a 3.5mm to 6.3mm jack lead.
The USB type A plug (4) 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 (6) 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 (5) and
connect the 6.3mm plug to the appropriate microphone input jack on the mixer
or amplifier.
Note: The output of both of the handheld transmitters is mixed to the same
single 3.5mm output.
Each handheld transmitter has an on/off switch (2), which should be in the down
position (off). Unscrew the bottom battery compartment (3) and insert 2 x AA
alkaline batteries, ensuring that the polarity is the correct way around.
Move the switch up to the “on” position and the power indicator (1) should light
briefly. If this LED is lit constantly, this indicates that the batteries are low on
charge and need replacing with new ones.
Gradually turn up the volume level on the mixer or amplifier and speak into the
handheld microphones in turn until the sound can be heard through the speakers
or recording equipment. Increase the volume to the required level.
When either or both of the microphones is not being used for a short time, it is
possible to mute the output by sliding the on/off switch to the central “mute”
position. This maintains the radio carrier signal but mutes the sound until the
switch is moved back to the “on” position.
If the U-MIC set is not being used for longer periods, turn down the volume level
on the connected mixer or amplifier and switch both handheld microphones off.
For long term storage, unplug the jack and USB receiver and remove the
batteries form the handheld transmitters.
