BLX1 Bodypack Transmitter
The lightweight yet rugged build of the BLX1 means you don’t have to worry about damage during everyday use, and it easily clips onto a belt, pocket, or guitar strap for optimal placement.

It’s capable of up to 300 feet line-of-sight operation, while it boasts a battery life of up to 14 hours, with an LED status indicator to warn you when it’s time to recharge. Turn the transmitter on and off and control your gain with controls on the bodypack itself. Its group and channel selection buttons enable quick frequency matching with the receiver.
