Introducing the Micro E3 KR-787

The E3 KR-787 is a wireless microphone system that uses the UHF 610–920MHz frequency band, minimizing interference and ensuring stable signal transmission in various environments.

With a signal-to-noise ratio (S/N) above 105dB, harmonic distortion below 0,7%, and a frequency response range of 45Hz – 18kHz, the E3 KR-787 reproduces clear, detailed, and faithful sound.

Technical parameters of the product to consider:

• Stable operation on the UHF band: The Micro E3 KR-787 uses the UHF frequency band of 610–920MHz, which helps to minimize interference and maintain a stable signal even in environments with many wireless devices operating simultaneously.
• PLL technology enhances connection stability: The system is equipped with PLL (Phase Locked Loop), which accurately locks the frequency, reducing frequency drift and minimizing connection loss during continuous use.
• A 2-channel receiver meets the needs of duets: The receiver supports two independent channels, allowing two microphones to operate simultaneously while maintaining stable sound quality, making it suitable for karaoke, conferences, and performances.
• Clear sound with high signal-to-noise ratio and low THD: With a signal-to-noise ratio (S/N) above 105dB, THD below 0,7%, and a frequency range of 45Hz – 18kHz, the device delivers accurate sound reproduction, reduces background noise, and minimizes distortion.
• Operating range up to 120 meters: A transmission range of 120 meters allows users to move freely on stage or in the auditorium while ensuring stable signal transmission.
• Flexible connectivity with multiple devices: The receiver features integrated balanced XLR and 6.3mm jacks, making it easy to connect with digital processors, mixers, karaoke amplifiers, and professional sound systems.
• Long-lasting battery life: Each microphone uses 2 AA batteries and has a continuous operating time of approximately 12 hours, which is sufficient for extended events.
