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 H9 frequency band between 512 to 542 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 BLX2 transmitter to match. A dual-colored LED indicator displays green for normal audio levels and red to alert you if your levels are clipping. The unit has a microprocessor-controlled internal diversity antenna to prevent interference and dropouts.
