Use the supplied USB-C charging cable and connect to a USB-C 5V power source, such as a computer or power bank. The power indicator will show red while charging and turn blue when fully charged.

What is the battery life of the transmitter and receiver?

The receiver (Vlink2 RX) has a built-in 3000mAh battery offering up to 19 hours of use. The body-pack transmitter (Vlink2 TX) has a 2000mAh battery offering up to 20 hours. The handheld transmitter (Vlink2 HU) with the supplied Li-ion battery lasts up to 22 hours, or 20 hours with two AA batteries.

What is the maximum operating range?

The Vlink2 TX and RX have an operating range of up to 100 meters (328 feet) in open air. The handheld transmitter Vlink2 HU has a range of up to 50 meters (164 feet). Actual range may vary due to obstacles and interference.

Can I use this microphone system with a smartphone?

Yes, the receiver includes a 3.5mm TRRS locking-type audio cable for smartphones. Connect the cable to the receiver's LINE OUT jack and plug the other end into your smartphone's headphone jack. Alternatively, you can use an adapter if needed.

How do I adjust the microphone gain?

On the transmitter, press the SET button to access the menu, navigate to 'Mic Gain' using the +/- buttons, then adjust the level from 0 to 9 (default 6). On the receiver, you can also adjust the external microphone gain from 0 to 19 (default 16) using the menu.
