The BLX24 Vocal Wireless System with SM58 Mic from Shure includes a BLX4 wireless receiver and a BLX2 handheld transmitter with an SM58 microphone. This system is set to Shure’s M15 frequency band between 662 to 686 MHz. The system has up to a 300′ line-of-sight range of operation and is designed for easy setup.
The BLX4 receiver’s one-touch QuickScan frequency selection finds the clearest available channel and tunes the unit to it. Its front panel LCD display indicates the group and channel it is tuned to, allowing you to set the BXLR2 transmitter to match. A dual-coloured LED indicator displays green for normal audio levels and red to alert you if your levels are clipping. The two antennas have microprocessor controlled internal diversity to help prevent interference.
Two included AA batteries provide the BLX2 transmitter with up to 14 hours of operation. You can use up to 12 compatible BLX systems simultaneously per frequency band.
