The device boasts a signal-to-noise ratio (S/N) of over 100dB, total harmonic distortion (THD) below 0,02%, and a frequency response range of 40Hz – 16kHz, enabling clear, faithful reproduction of speech and vocals with high detail.

Technical parameters of the product to consider:

• UHF frequency range 580 – 937MHz: The receiver, handheld microphone, and belt-worn transmitter all operate on the wide UHF frequency band of 580–937MHz, reducing interference, increasing frequency selectivity, and ensuring stable signals even in environments with many wireless devices.
• Maximum frequency deviation: 15kHz The appropriate frequency offset helps stabilize the transmitted signal, minimize distortion, and ensure sound quality during transmission and reception.
• Signal-to-noise ratio (S/N) >100dB: A high signal-to-noise ratio significantly reduces background noise, resulting in clean, clear sound and enhanced detail reproduction of vocals and speech.
• Total harmonic distortion (THD) is below 0,02%: With extremely low distortion, the E3 TR-820 II delivers realistic sound, minimizing crackling even at high volumes or for extended periods.
• Frequency stability 0,03%: The ability to maintain a stable frequency helps the device minimize frequency drift, reduce the risk of connection loss, and ensure a stable signal throughout operation.
• Frequency response range 40Hz – 16kHz: The device reproduces the full-range sound from low to high frequencies well, resulting in rich, clear vocals suitable for karaoke, conferences, and performances.
• Dynamic Range >100dB: A wide dynamic range allows the microphone to handle both soft and loud sounds well while maintaining detail and minimizing distortion when the user changes the intensity of their speech or singing.
• RF transmit power 8,5mW: Handheld microphones and belt-worn transmitters utilize appropriate transmission power, ensuring stable signals while saving energy and extending battery life.
• Battery life: 10-12 hours Handheld microphones and belt-worn transmitters can operate continuously for 10 to 12 hours, making them ideal for extended performances, conferences, or karaoke sessions.
• Flexible power supply: The receiver supports both 12-15V DC and 100-240V AC power sources, ensuring stable operation under various power conditions.
• Operating in harsh environments: With the ability to operate at temperatures from -20°C to 50°C, the E3 TR-820 II is suitable for both indoor and outdoor spaces, making it ideal for events and performances.
