Cardioid Condenser Headset Microphone
Unidirectional Cardioid Polar Pattern
The unidirectional cardioid polar pattern captures primarily the user's voice while rejecting ambient noise from the sides and rear. This is ideal for noisy environments such as fitness classes.
Electret Condenser Construction
The electret condenser construction provides superior sensitivity and extended frequency response. This ensures clear and natural voice capture.
Sweat-Resistant Hydrophobic Materials
Resistance to Sweat and Corrosion
The special hydrophobic materials resist sweat, moisture, and corrosion. This is critical for fitness instructors who use the microphone during intense workouts.
Extreme Durability
The rugged and durable construction ensures that the microphone survives extreme moisture and sweat conditions. The durability is exceptional for demanding applications.
TA4F Connector Compatible with Shure Wireless Systems
4-Pin TA4F Connector (TQG)
The 4-pin TA4F connector (TQG) is compatible with Shure BLX and GLX-D wireless systems. This allows for direct replacement of existing wireless microphones.
Universal Compatibility
Compatibility with multiple Shure wireless systems provides flexibility. This is ideal for users with existing wireless systems.
Extended Frequency Response
45Hz to 20kHz
The frequency response of 45Hz to 20kHz provides full coverage of the human voice range. This ensures clear and natural voice reproduction.
Optimal Sensitivity
Optimal sensitivity allows for clear voice capture even in noisy environments. The sensitivity is ideal for instructors who need to project their voice.
Ergonomic Headworn Design
Comfortable for Long-term Use
The ergonomic headworn design is comfortable for prolonged use during fitness classes. Comfort is important for instructors who use the microphone for hours.
Discreet Fit
The discreet fit over the head allows for freedom of movement. This is ideal for instructors who move around during classes.
