Frequently Asked Questions - U-Mic 171.812UK Qtx

How do I power the U-Mic receiver?

Connect the USB Type A plug (6) on the receiver to a USB port providing 5V, 1000mA. This can be from a USB power adapter, power bank, or computer port.

Can I use the receiver with a U-Disk player?

Yes, you can connect a USB stick or other peripheral to the USB Type A socket (8) on the rear of the receiver. The USB only supplies power; audio is not transmitted via USB.

How do I pair the beltpack transmitters with the receiver?

The U-Mic uses fixed frequencies (863.2 MHz and 864.8 MHz). No pairing is required; just turn on the transmitters and receiver, and they will communicate automatically.

What batteries do the transmitters need?

Each beltpack requires 2 x AA alkaline batteries. Ensure correct polarity when inserting them into the battery compartment (5).

How do I adjust the microphone volume?

Turn the volume control (1) on top of each beltpack transmitter gradually, and adjust the input level on your mixer or amplifier accordingly.

Why is there no sound from the microphones?

Check that the transmitters are turned on (switch down), batteries are installed correctly, the receiver is powered, and the 3.5mm to 6.3mm jack is securely connected to the mixer/amplifier input.

What is the wireless range of the U-Mic?

The system can operate up to 50 meters in open line-of-sight conditions. Obstacles like walls may reduce range.

Can I use the U-Mic with a PA system?

Yes, connect the 6.3mm plug of the included cable to a microphone input on your PA system or mixer. Ensure the volume is turned down initially to avoid feedback.

How do I clean and maintain the U-Mic?

Wipe the exterior with a dry cloth. For long-term storage, remove the batteries from the transmitters and unplug the receiver. Keep away from moisture and extreme temperatures.

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.
