- TQG connection for use with Shure lavalier, headset, earset and instrument microphones and guitar cables
- Easily accessible On / Off switch
BLX4R Rack Mount Receiver
Rack-mountable and featuring rugged metal construction, the BLX4R offers simple setup and intuitive controls. One-touch QuickScan frequency selection quickly locates the best open frequency in case of interference. Removable antennas allow for quick antenna distribution. For use with BLX Wireless Systems. Rack mount kit is included.
Features
- XLR and ¼" output connectors
- Microprocessor-controlled internal antenna diversity
- Two-color audio status indicator LED
- -Green: Normal audio levels
- -Red: Excessive audio levels (overload / clipping)
- Adjustable output level
- LCD display with detailed RF and audio metering
WB98H/C Instrument Microphone
The WB98H/C is premium wireless cardioid condenser instrument microphones that clamp onto the bell of wind instruments or onto the rim of percussion instruments. The integrated gooseneck and ratcheting swivel joint allows the mic to be easily positioned and secured, and an isolation shock-mount reduces the transmission of instrument 'key noise' and other mechanical noise. A gooseneck angle brace is included to provide better retention of the microphone placement during more active performances.
Features
- The WB98 H/C feature transformerless preamplifier circuitry which improves linearity across the full frequency range
- The pickup pattern provides high gain-before-feedback and excellent rejection of unwanted noise
- Its high maximum sound pressure level (SPL) enables it to handle the extreme demands of brass, woodwind and percussion instruments
- The WB98H/C features a 1.6 m (5.3ft) high-flex cable terminating in a 4-pin mini-connector, for use with wireless bodypack transmitters
- Tailored frequency response for open, natural sound reproduction
- Compact, lightweight construction provides a low degree of visibility
- Gooseneck, ratcheting swivel joint and gooseneck angle brace allow for optimum placement and fixed positioning
- Legendary Shure ruggedness and reliability
