The BLX288 Dual-Channel Handheld Wireless System with 2 PG58 Handheld Mics from Shure includes a BLX88 dual-channel wireless receiver and two BLX2 handheld transmitters, both with PG58 microphones. The system is set to Shure's M15 frequency band and operates between 662 to 686 MHz.
Both of the BLX2 handheld transmitters have a 300' line of sight operation range with the BLX88 receiver. They are each powered by two included AA batteries that can provide up to 14 hours of operation. The BLX88 receiver features microprocessor-controlled internal antenna diversity that helps prevent interference and signal dropouts. Its one-touch QuickScan feature detects the most interference-free frequency and sets the channel to it for fast setup. The PG58 microphone features an on/off switch on the mic body and is tuned for vocal applications.
