Analog wireless receiver provides improved linearity and frequency response with group and channel scan for easy set-up. Features include microprocessor internal antenna diversity, frequency QuickScan, and two-color audio status indicator LED. The durable BLX4 features simple setup, intuitive controls, and microprocessor-controlled internal antenna diversity. One-touch QuickScan frequency selection quickly locates the best open frequency in case of interference. For use with BLX Wireless Systems.
Shure BLX Wireless Systems combine professional-quality sound with simple setup and an intuitive interface for legendary audio performance right out of the box. Precision-built and available in a variety of configurations, it's the most accessible way to own the stage. If you've ever heard someone sing or speak into a live microphone, there's an excellent chance it was an SM58. Rock stars. Pop idols. Comedians. Presidents. Popes. Immortal words have passed through its iconic grille for generations. And with engineering and durability that set the world standard, it's sure to keep turning up at legendary performances. Made to handle voice with clarity and care, the uniform cardioid polar pattern reproduces every note as it was intended. And it leaves background noise behind. On any stage—from the club show to the stadium—the SM58 delivers warm, crisp sound time after time. Roll with no shake or rattle - Handling noise gets absorbed by the pneumatic shock mount, keeping the sound free of vibration. When wind and plosives try to take over, the spherical mesh grille and built-in pop filter keep them out of the mix. Taking the show on tour? The mic's durable construction and the break-resistant mic clip keep the SM58 going strong through the toughest performances.

Shure BLX24/SM58 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.
