The all-new BP-300 metal bodypack transmitter is rugged, compact, and easy to use. Using two AA batteries for 14 hours of use, the BP-300 is one of the most economical transmitters available for day-to-day operation. The unit’s mute function keeps the RF signal live while muting the audio, protecting your channel and preventing noise in the audio system. Two preconfigured bodypack systems are available, with either a lapel or a headworn microphone. The bodypack’s TA4 connector allows the unit to be used with other Electro-Voice lapel or headworn microphones.
