The QuickScan frequency selection feature of the BLX4 receiver, with one touch, finds the available channel with the clearest signal and automatically tunes to it. Its LCD screen on the front panel indicates the tuned group and channel, allowing the BLX2 transmitter to be set to match. A bi-color LED indicator shows green for normal audio levels and red to alert if levels are peaking. The unit features an internal diversity antenna controlled by a microprocessor to avoid interference and signal dropouts.
The two included AA batteries provide the BLX2 transmitter with up to 14 hours of operation. Up to 12 compatible BLX systems can be used simultaneously per frequency band.
