Microphone E3 KR-788

The E3 KR-788 wireless microphone is a 2-channel UHF microphone system designed for karaoke, conferences, and professional performances.

This product utilizes phase-locked PLL technology, supporting two microphones operating simultaneously, with a transmission range of up to 120 meters, providing stable signal transmission, clear sound, and up to 12 hours of continuous use.

Introducing the Micro E3 KR-788

The E3 KR-788 is a wireless microphone system operating on the UHF band (610–920MHz), which helps minimize interference and ensures stable signals 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-788 reproduces vocals and speech faithfully, clearly, and with minimal background noise.

Technical parameters of the product to consider:

• The UHF band (610–920MHz) has limited interference: The E3 KR-788 operates on the UHF band of 610–920MHz, which helps reduce interference from other signals and maintain a stable signal under various usage conditions, especially in areas with many wireless devices.
• PLL technology increases signal transmission stability: The device uses a PLL (Phase Locked Loop) to precisely lock the frequency, minimizing signal loss and drift, and ensuring continuous signal transmission throughout use.
• Independent dual-channel receiving system: The receiver supports two separate channels, allowing two microphones to operate simultaneously without interfering with each other. This is ideal for karaoke duets, conferences, and hosting events.
• Clear and realistic sound quality: With a signal-to-noise ratio (S/N) above 105dB, THD below 0,7%, and a frequency range of 45Hz – 18kHz, the E3 KR-788 reproduces speech and vocals in detail, reduces background noise, and minimizes distortion at high volume levels.
• Operating range up to 120 meters: A transmission range of 120 meters provides users with flexibility when moving around the stage, auditorium, or event area while ensuring a stable signal.
• Diverse connectivity options with your audio system: The receiver is equipped with balanced XLR and 6.3mm jack outputs, making it easy to connect with digital processors, mixers, karaoke amplifiers, power amplifiers, and many professional sound systems.
• Battery life meets the needs of continuous use: The two microphones use 2 AA batteries and have an operating time of approximately 12 hours, ensuring stable operation during karaoke sessions, conferences, or extended performances.
