Micro E3 UR-400

The E3 UR-400 wireless microphone system is a professional 4-channel UHF microphone system designed to meet the needs of karaoke, conferences, stage performances, and events. The product stands out with its stable signal transmission and reception, clear sound quality, and support for various transmitters, offering flexibility for many applications.

Introducing the Micro E3 UR-400

The Micro E3 UR-400 is a professional 4-channel UHF wireless microphone system operating on the UHF frequency range of 610-920MHz with 4 independent channels. It utilizes PLL (Phase Locked Loop) technology to ensure stable signal transmission, reduce interference, and minimize signal loss.

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 clear sound quality and realistic reproduction of vocals and speech.

Technical parameters of the product to consider:

• UHF frequency range 610 – 920MHz: The system operates on a wide UHF frequency band, which helps to minimize interference, increase the ability to select the appropriate frequency, and ensure stable signals in environments with many wireless devices.
• Independent 4-channel receiver: The receiver supports 4 channels simultaneously, allowing for the simultaneous connection of multiple microphones or transmitters, making it suitable for conferences, stage performances, commercial karaoke, and live shows.
• PLL (Phase Locked Loop) technology: Both the receiver and transmitter utilize a PLL phase-locked circuit to maintain a stable frequency, minimize frequency drift, and reduce the risk of connection loss during use.
• Bandwidth of 30MHz (receiver) and 120MHz (transmitter): Wide bandwidth allows for greater flexibility in selecting operating frequencies, reducing frequency overlap when using multiple microphones simultaneously.
• High receiver sensitivity: With a sensitivity of 25kHz, an input of 6dBv, and a signal-to-noise ratio (S/N) of >60dB, the receiver easily picks up signals from transmitters even at relatively long distances.
• Maximum frequency deviation ±45kHz: It helps stabilize signal transmission, minimize distortion, and ensure 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 help reproduce sound faithfully, minimizing crackling or popping sounds when used at high volume.
• Frequency response range 45Hz – 18kHz: The device reproduces bass, mid, and treble frequencies well, making it suitable for singing, speeches, conferences, and performances.
• Effective operating range up to 100m: Ensure users can move freely on stage or in the auditorium while maintaining a stable signal.
• RF transmit power 15mW: The appropriate power level helps the transmitter maintain a strong, stable signal while optimizing energy consumption.
• Battery life up to 12 hours: Handheld microphones, wearable transmitters, and conference microphones can all operate continuously for approximately 12 hours, making them well-suited for extended programs.
• Conference microphones using condenser receivers: The condenser microphone has high sensitivity, capturing clear and detailed voice, making it suitable for meetings, conferences, presentations, or speeches.
• Flexible combination ability: The Micro E3 UR-400 easily connects to digital processors, mixers, amplifiers, power amplifiers, and professional speaker systems, making it suitable for a wide range of sound configurations from home karaoke to auditoriums and stages.
