The BLX288/PG58 Dual-Transmitter Handheld Wireless System from Shure includes a BLX88 dual-channel wireless receiver and two BLX2 handheld transmitters, both with PG58 microphone capsules.
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 operate for up to 14 hours. 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 BLX2 handheld transmitters feature an on/off switch on the mic body and are tuned for vocal applications.
