The E3 PR-3800 wireless microphone is a professional UHF microphone developed to meet the needs of high-end karaoke systems, conferences, stages, and events.

The receiver operates on the UHF frequency band of 610–937MHz and utilizes PLL (Phase Locked Loop) technology, ensuring stable signals, reducing frequency drift, and minimizing interference in environments with many wireless devices.

Technical parameters of the product to consider:

• UHF carrier frequency range: 610 – 937MHz: Operating on the wide UHF frequency band, the microphone provides stable signal transmission, minimizes interference from other electronic devices, and ensures sound quality in various environments.
• Two independent channels system: The receiver supports two channels operating simultaneously, allowing the use of two microphones at the same time without frequency overlap or affecting signal quality.
• 32 preset channels: Users can easily select and switch frequencies suitable for their environment, minimizing interference when multiple microphone systems are operating simultaneously.
• PLL frequency locking technology: Both the receiver and transmitter utilize Phase Locked Loop (PLL) technology, which helps maintain a stable frequency with an error of only ±0,005%, reducing frequency drift and improving operational reliability.
• High sensitivity: With a sensitivity of 6dBμV at a frequency deviation of 25KHz and a signal-to-noise ratio above 60dB, the receiver is capable of receiving signals well even when the distance between the microphone and the receiver is quite far.
• Receiver bandwidth 30MHz: It supports multiple operating frequency options, making the system more flexible when installed in areas with high radio wave density.
• Maximum frequency deviation ±45KHz: It helps stabilize the signal transmission, ensuring clear sound quality and minimizing distortion.
• Total harmonic distortion (THD) is below 0,7% @1KHz: Ensures accurate sound output and minimizes distortion when singing or speaking at high volume levels.
• Frequency response 45Hz – 18kHz (±3dB): It fully reproduces the important frequency ranges of speech and vocals, resulting in balanced, detailed, and natural sound.
• Operating range up to 300 meters: This is a key advantage of the E3 PR-3800, effectively meeting the needs of use in large stages, auditoriums, convention centers, or outdoor events while maintaining a stable signal.
• Handheld microphones using a Cardioid directional dynamic pickup: The heart-shaped pickup pattern design helps focus on capturing vocals from the front, minimizing ambient noise and reducing feedback during use.
• RF transmit power 30mW: High transmission power enhances the ability to transmit stable signals over long distances, making it particularly suitable for large-scale performances or conferences.
• Wearable microphones use condenser receivers: Offering high sensitivity, capturing clear and natural voices, it's suitable for MCs, speakers, lecturers, or presenters.
• Mini XLR 4-pin connector on the wearable transmitter: Allows for a secure connection with a lavalier microphone or dedicated headset microphone, ensuring a stable signal throughout use.
• Flexible power source: The receiver uses a 100-240V AC power source, making it compatible with various electrical systems and convenient for installation and use.
• Long battery life: The handheld microphone uses 2 AA batteries and has a continuous operating time of over 10 hours, while the wearable transmitter uses 1 AA battery and can operate for over 8 hours, effectively meeting the needs of extended programs without frequent battery changes.
• Balanced XLR and 6.3mm jack outputs: It supports connection with various devices such as digital processors, mixers, amplifiers, or power amplifiers, making sound system setup easier and more professional.
