SHURE BLX24RA/B58-M19 ไมโครโฟนไร้สาย ไมค์ลอยแบบไมค์เดี่ยว คลื่นความถี่ 694-703 MHz
The BLX24R/B58 Handheld Wireless System with Beta 58A Mic from Shure includes a BLX4R single-channel wireless receiver and a BLX2 handheld transmitter with a Beta 58A microphone cartridge. This system is set to Shure’s M19 frequency band between 694 to 703 MHz. The system has up to a 300′ line-of-sight range of operation and is designed for easy setup.
The BLX4R 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 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.
