Micro E3 UR-680

The E3 UR-680 wireless microphone system is a professional 2-channel UHF microphone system designed for home karaoke, commercial karaoke, auditoriums, and stages. The device stands out with its stable signal transmission and reception, clear sound, and an operating range of up to 100 meters, providing a flexible user experience in various spaces.

Introducing the Micro E3 UR-680

The E3 UR-680 wireless microphone system is a 2-channel UHF microphone system operating on the UHF frequency range of 610 – 920MHz with two independent channels, using PLL (Phase Locked Loop) technology to ensure stable signal and reduce frequency drift during use.

The device boasts a signal-to-noise ratio (S/N) of over 105dB, total harmonic distortion (THD) below 0,7%, and a frequency response range of 45Hz – 18kHz, delivering accurate and clear reproduction of vocals and speech.

Technical parameters of the product to consider:

• UHF frequency range 610 – 920MHz: The device operates on a wide UHF frequency band, which helps to minimize interference from other electronic devices and increases the ability to select a suitable frequency in a variety of environments.
• Independent 2-channel receiver: Allows for the simultaneous use of two microphones on the same receiver, ideal for duets, hosting events, conferences, or presentations.
• PLL (Phase Locked Loop) technology: Both the receiver and microphone utilize a PLL phase-locked circuit to maintain a stable frequency, minimize frequency drift, reduce signal loss, and increase reliability during operation.
• Bandwidth 30MHz (receiver) and 120MHz (microphone): Wide bandwidth allows the system to easily select the appropriate operating frequency, reducing channel overlap when installed in environments with many wireless devices.
• High receiver sensitivity: With a 25kHz offset, 6dBv input, and a signal-to-noise ratio of >60dB, the receiver provides stable signal reception, ensuring clear audio even when the user moves within the operating range.
• Maximum frequency deviation ±45kHz: It helps stabilize signal transmission, reduce distortion, and maintain sound quality throughout use.
• Signal-to-noise ratio (S/N) >105dB: A high signal-to-noise ratio (S/N) helps reduce background noise, resulting in clean, clear sound and preserving the detail of vocals and speech.
• Total Harmonic Distortion (THD) <0,7%: Low distortion levels ensure accurate sound reproduction, minimizing crackling or popping sounds even at high volume levels.
• Frequency response range 45Hz – 18kHz: This device reproduces the full frequency range from low to high, resulting in bright, clear vocals and is suitable for various uses such as karaoke, speeches, or performances.
• Dynamic microphone head: Using a highly durable dynamic receiver, capable of withstanding high sound pressure, minimizes feedback and is suitable for karaoke and stage environments.
• RF transmit power 15mW: Ensures strong and stable signal transmission over a wide operating range, while optimizing power consumption.
• Operating range up to 100 meters: It allows users to move freely on stage, in auditoriums, or in large spaces while maintaining a stable connection.
• Battery life is approximately 12 hours. The microphone uses 2 AA batteries and has a continuous operating time of up to 12 hours, making it suitable for extended programs without the need for frequent battery changes.
• XLR and 6.35mm jack outputs: The receiver is equipped with both balanced XLR and 6.35mm jacks, allowing for convenient connection to digital processors, mixers, amplifiers, power amplifiers, and many other sound systems.
