Making the jump to wireless should be liberating, not challenging. Shure BLX Wireless Systems combine professional quality sound with simple setup and an intuitive interface for performance you can trust right out of the box. Precision built and available in a variety of handheld, lavalier, instrument and headset configurations, it's the most accessible way to own the stage.

Lavalier cardioid microphone provides superior source quality and vocal reproduction. It features construction for low visibility and a tailored frequency response for speaking and presentations. For professional presentations requiring a microphone that is heard but not seen, the Centraverse CVL Lavalier Condenser Microphone offers a compact clip-on design and simple, no-nonsense setup. The unidirectional cardioid polar pattern rejects unwanted sound for superior audio quality and vocal reproduction. Precision-engineered for years of use with all Shure wireless systems.

Shure BLX14/CVL Wireless Presenter System Features:

  • Up to 12 compatible systems per frequency band (region dependent.)
  • Microprocessor-controlled internal antenna diversity.
  • One-touch QuickScan frequency selection quickly locates the best frequency.
  • 1/4" and XLR audio outputs.
  • Two color audio status indicator LED.
  • Miniature lavalier microphone with included tie clip offers low visibility and hands-free use.
  • Permanently charged electret condenser element provides clear vocal reproduction.
  • Unidirectional cardioid polar pattern rejects unwanted noise for improved sound quality.
  • Included windscreen reduces plosives, wind, and breath sounds.
  • Tailored frequency response optimized for speaking and presentations.
  • TA4F (TQG) connector seamlessly integrates with Shure wireless systems.
  • Legendary Shure precision engineering for durability and performance.

Shure BLX14/CVL Specifications:
System
Working Range: 91 m (300 ft) Line of Sight (Actual range depends on RF signal absorption, reflection and interference.)
Audio Frequency Response: 50 to 15,000 Hz (Dependent on microphone type)
Total Harmonic Distortion (Ref. ±33 kHz deviation with 1 kHz tone): 0.5%, typical
Dynamic Range: 100 dB, A-weighted, typical
Operating Temperature: -18°C (0°F) to 57°C (135°F) (Battery characteristics may limit this range.)
Polarity: Positive pressure on microphone diaphragm (or positive voltage applied to tip of WA302 phone plug) produces positive voltage on pin 2 (with respect to pin 3 of low-impedance output) and the tip of the high impedance 1/4-inch output.
