Micro E3 M-68

The E3 M-68 wireless microphone is a professional UHF microphone designed for karaoke, conferences, and stage performances, offering stable signal transmission up to 100 meters. Utilizing PLL frequency locking technology, it provides effective interference resistance, ensuring clear sound and minimizing signal loss during use.

Introducing the Micro E3 M-68

The E3 M-68 wireless microphone is a high-end UHF microphone operating in the UHF frequency range of 510–920MHz. It incorporates Phase Locked Loop (PLL) frequency synthesis technology to maintain a stable signal, minimize interference, and reduce connection loss during use.

With a signal-to-noise ratio (S/N) above 105dB, total harmonic distortion (THD) below 0,7%, and a frequency response range from 45Hz to 18kHz, the product delivers clear, crisp, and accurate sound quality.

Technical parameters of the product to consider:

• UHF 510 – 920MHz transmission technology: The Micro E3 M-68 uses a wide UHF frequency band, ensuring stable signal transmission, reducing interference, and minimizing connection loss when used in various environments such as karaoke, auditoriums, or stages.
• Independent 2-channel receiver: The dual-channel design allows for the simultaneous use of two microphones or the combination of handheld microphones with a belt-worn transmitter, providing flexibility for performances, conferences, and presentations.
• PLL phase-locked frequency synthesis technology: The PLL system helps to precisely lock the frequency, ensuring a stable signal, minimizing frequency drift, and reducing interference during prolonged operation.
• Bandwidth of 30MHz on the receiver and 120MHz on the transmitter: It offers the ability to select multiple operating frequencies, reducing the risk of interference when used simultaneously with other wireless devices.
• High sensitivity and stable signal reception: With a frequency offset of 25kHz, an input gain of 6dBv, and a signal-to-noise ratio of >60dB, the receiver is capable of receiving signals well, ensuring stable microphone operation even when the user moves around a wide area.
• Signal-to-noise ratio (S/N) >105dB: This is a crucial parameter that helps reduce background noise, resulting in clean, clear sound quality and increased detail for both vocals and speech.
• Total Harmonic Distortion (THD) <0,7% @ 1kHz: Low distortion levels ensure accurate sound output, minimizing crackling or sound distortion even at high volume levels.
• Frequency response range: 45Hz – 18kHz (±3dB) It allows for the full reproduction of the sound spectrum from low to high frequencies, resulting in clear, crisp vocals suitable for a wide range of musical genres.
• Dynamic handheld microphone and condenser belt-worn transmitter: Dynamic microphones are highly durable and can withstand sound pressure well, making them suitable for singing; while belt-worn transmitters use high-sensitivity condenser microphones, ideal for presentations, conferences, and teaching.
• RF transmit power 15mW: It ensures a strong and stable signal transmission within an operating range of up to 100 meters, effectively meeting the needs of use in large spaces.
• Long battery life: The handheld microphone uses 2 AA batteries for approximately 12 hours of continuous operation, while the belt-worn transmitter uses 1 AA battery with a lifespan of about 8 hours, suitable for extended programs.
