This bodypack from the U300 series operates in the 655 - 679 MHz frequency band and features a mini-XLR input with three-position level switch for adaptation to microphones such as active and passive instruments. It has an output power of 10 mW and, due to its frequency response of 25 Hz - 16 kHz, is also suitable for transmitting 5-string bass guitars with a low H-string.

The LD-Systems U306 BP reaches over 10 hours running time with two AA batteries, is conveniently synchronized via infrared with the U306 receiver, and a pilot tone ensures trouble-free operation. The practical standby position of the operating switch enables temporary muting.
