Shure BLX1288/CVL Dual-Channel Wireless Microphone System

The Shure BLX1288/CVL is a dual-channel wireless microphone system that combines a handheld vocal microphone and a lavalier microphone system in one package. Designed for presentations, houses of worship, schools, events, public speaking, and live performances, the system allows two wireless microphones to be used simultaneously through a single dual-channel receiver.

The system includes a BLX88 dual-channel wireless receiver, BLX1 bodypack transmitter, CVL Centraverse lavalier microphone, and BLX2/PG58 handheld wireless transmitter. This combination provides the flexibility to equip one person with a discreet lavalier microphone while a second person uses a handheld microphone.

Two Wireless Microphones in One System

The BLX1288/CVL provides two independent wireless channels through the included BLX88 dual-channel receiver.

This makes the system particularly useful when an application requires both a presenter-style lavalier microphone and a handheld microphone.

Typical applications include:

• Presentations
• Houses of worship
• Schools and classrooms
• Corporate meetings
• Public speaking
• Live events
• Training sessions
• Community facilities
• Stage performances

BLX88 Dual-Channel Wireless Receiver

At the center of the system is the Shure BLX88, which receives both wireless microphone channels simultaneously.

The receiver uses microprocessor-controlled internal antenna diversity and Shure's one-touch QuickScan frequency selection to help locate an available frequency for operation.

Front-panel dual-color LED indicators provide quick audio status monitoring, displaying green during normal operation and red when the audio signal is clipping.

For connection to professional audio equipment, the BLX88 provides:

• Two XLR outputs
• Two 1/4-inch outputs

The independent outputs make it easy to connect the two wireless channels to separate mixer or audio-system inputs.

BLX1 Bodypack Transmitter

The included Shure BLX1 bodypack transmitter connects to the CVL lavalier microphone through its TQG input.

The compact bodypack features adjustable gain and an easily accessible On/Off switch for convenient operation during presentations and performances.

Powered by two AA alkaline batteries, the BLX1 provides up to 14 hours of battery life, making it suitable for extended events, services, classes, and performances.

The TQG input also makes the BLX1 compatible with select Shure headset, earset, lavalier, and instrument microphones when properly matched to the system.

CVL Centraverse Lavalier Microphone

The included Shure CVL Centraverse is a compact electret condenser lavalier microphone designed primarily for speech and presentation applications.

Its cardioid pickup pattern helps focus pickup toward the person speaking while reducing unwanted sound from the surrounding environment.

A tailored frequency response helps provide clear, intelligible speech, while its compact design allows discreet placement on clothing.

The CVL terminates in a TA4F connector for connection to the included BLX1 bodypack transmitter.

BLX2/PG58 Handheld Wireless Microphone

The system also includes a BLX2 handheld wireless transmitter with a PG58 microphone capsule.

This provides a traditional handheld microphone for a second presenter, vocalist, speaker, or performer while the BLX1/CVL combination operates simultaneously on the other receiver channel.

The combination of handheld and lavalier microphones makes the BLX1288/CVL especially useful for applications that require different microphone styles within the same wireless system.

QuickScan Frequency Selection

The BLX88 receiver features one-touch QuickScan frequency selection, simplifying wireless setup by helping identify an available operating frequency.

This makes the BLX system easier to configure for users who need dependable wireless operation without a complicated frequency setup process.

Wireless performance can vary depending on RF conditions, physical obstructions, interference, and the operating environment.

Important Frequency Band Information

Shure BLX wireless systems are available in different frequency-band versions.

When replacing or adding individual wireless components, the frequency band of the transmitter must be compatible with the receiver. A transmitter from a different frequency band cannot simply be substituted for the correct version.

Check the frequency band of the BLX1288/CVL version being ordered before purchasing replacement transmitters or other wireless components.

If you're unsure which Shure frequency band you need, contact Audio Supply and we can help verify compatibility before ordering.
