Product Overview
The Shure BLX1288/W85 is a cost-effective Dual-Channel Wireless Combo Lavalier & Handheld Microphone System for two presenters, speakers, teachers or lecturers. It offers quality sound, simple setup and dependable performance right out of the box. The system features the compact and lightweight BLX88 dual-channel tabletop receiver with internal antennas, ideal for portable use.
This BLX1288/W85 combo offers a flexible solution by including a bodypack transmitter with a WL185 cardioid lavalier mic and a handheld transmitter equipped with the legendary SM58 cardioid dynamic capsule. The lav provides a discreet hands-free mic option, while the handheld mic is ideal in situations where you don't have time to position a lavalier mic or you need to quickly pass the mic between several people.
The receiver features one-touch QuickScan frequency selection to quickly search 123 available frequencies and locate a clean RF channel in case of interference. The system provides up to 14 hours of continuous use with four AA batteries at a range up to 300'. Up to 12 mic channels can operate simultaneously in each frequency band.
This streamlined wireless system from Shure is well suited for presentations and events in small venues, wedding halls, and houses of worship as well as conference, educational and corporate facilities.
