The systems consists of a 320UPR receiver and two 30BT body-pack transmitters with lapel microphones.
Smaller and lighter than all previous units, the 320UPR is a discrete dual-channel UHF receiver offering a choice of 240 user-selectable frequencies for each channel, and features stereo output, digital LCD displays with multi-function readout, and separate Power On/Off switches for each channel. The 320UPR operates on just 2 "AA" batteries (not included) and has a unique dual-function DC jack. Optional NiMH batteries can be recharged while in the 320UPR, or the receiver can be powered from an external, optional power supply.
Additionally, the 320UPR comes with both dual-plug XLR and a stereo mini-plug output cable, a removable shoe-mount, and flexible high-gain antennas.
The 30BT body-pack transmitter is the match for the 300UPR and 320UPR receivers. It provides the same selectable 240 UHF frequencies (794-806MHz) and features a digital display for frequency selection and battery strength. Power is provided by a pair of "AA" batteries (not included). Comes with the EX-503L lavalier microphone.
