Operating Frequencies and Modulation: The system operates within the UHF Band D (656.125 to 678.500 MHz) ensuring stable wireless performance. It uses FM modulation with ±40 kHz maximum deviation for clear sound transmission and minimal interference.

Wide Frequency Response: With a frequency response from 100 Hz to 15 kHz, it captures natural and clear vocals, suitable for various speaking and singing applications.

True Diversity Receiver: The ATW-R2100c receiver uses true diversity technology to reduce dropouts and interference, providing reliable signal reception over a typical 100-meter range.

High-Quality Handheld Microphone: The included ATW-T220c handheld transmitter features a cardioid dynamic microphone element, which rejects off-axis noise and improves vocal clarity. It also offers switchable RF power output (10 or 30 mW) to optimize range and battery life.

Long Battery Life and Compatibility: Powered by two AA alkaline or NiMH batteries, it provides up to 9 hours of operation on low power. The system supports rechargeable NiMH batteries with the ATW-CHG2 charger, promoting sustainability.

Robust Build and Accessories: The microphone system includes a Quiet-Flex™ stand clamp for easy setup. The receiver features balanced XLR and unbalanced 1/4″ outputs with audio output attenuation options, allowing flexible integration into sound systems.

User-Friendly Controls and Monitoring: The receiver displays clear RF and audio signal indicators, making frequency management and monitoring straightforward for live events.
