This bodypack from the LD-Systems U300 series operates in the frequency bands 823 - 832 MHz, 863 - 865 MHz and has a mini-XLR input with three-level 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 U308 BP reaches over 10 hours running time with two AA batteries, is conveniently synchronized via infrared with the U308 receiver, and a pilot tone ensures trouble-free operation. The practical standby position of the operating switch enables temporary muting.
