With a lower cut-off frequency of 25 Hz, the bodypack is also suitable for transmitting 5-string bass guitars with a deep H string. The bodypack’s input level can be adjusted to both active and passive guitars and basses over three levels. The power switch features a handy standby mode for temporary muting. The U300® receiver is fitted with a bright LCD channel display, an LED chain for displaying audio signal strength and both a balanced XLR and an unbalanced 6.35 mm audio output. The audio output can also be switched to instrument level for directly connecting to guitar and bass amplifiers.

The microphone characteristic can be changed using U500®-series replaceable heads.
