PG58 and CVL microphone dual systems for spoken word applications with analogue wireless transmission
The Shure BLX1288/CVL Wireless Dual Vocal System combines simple wireless setup, professional-grade performance, and two SM58 industry-standard vocal microphones to deliver warm and clear vocal reproduction.
The Shure BLX1288/CVL also includes a handheld transmitter equipped with an integrated PG58 dynamic cardioid microphone capsule. 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 two AA batteries, at a range up to 300'. Up to 12 mic channels can operate simultaneously in each frequency band.
This streamlined system is well suited for live performances and events in small venues, wedding halls, and houses of worship, as well as conference, educational, and corporate facilities.
PG58 Mic Capsule Optimized for Vocals and Speech
The PG58 dynamic capsule features a cardioid polar pattern that minimizes background noise and feedback. The built-in spherical wind and pop filter reduces plosives for clear and intelligible speech.
Lightweight Handheld Transmitter
The durable BLX2 handheld transmitter offers a lightweight, ergonomic design, and is comfortable to hold. Group and channel selection buttons allow for quick and simple frequency matching with the receiver. Other features include an easily accessible on/off button, adjustable gain control, and a black identification cap. The WA621 Color ID Caps kit containing assorted colored caps is available as an optional accessory.
Easy-to-Use Tabletop Receiver for Quality Audio
The BLX4 receiver employs a microprocessor-controlled internal antenna diversity feature to improve the quality and reliability of your wireless audio. An LED display shows group and channel settings, while two LED lights indicate when the system is ready for use and the strength of the incoming audio signal. The unit offers 1/4" and XLR outputs for connectivity to PA systems and mixing boards.
