Wireless Microphones System

rechargeable wireless 4 channel gooseneck microphone system noise cancelling desktop mic for meeting room speech OEM

ZR-E3404

1. The receiver is embedded with a professional DSP digital signal processing chip, serving as the audio processing core of the entire wireless conference microphone system.
2. The receiver adopts a 1.8-inch display screen, clearly showing the channel numbers, frequencies, microphone battery levels, volumes, microphone signals, audio levels, and more for the 4 channels at a glance.
3. The host provides independent volume control for dual channels, with each channel’s volume finely adjustable in 0–31 levels to suit different pickup scenarios.
4. The receiver has a built-in feedback (howling) suppression function that can be enabled or disabled as needed.
5. It is equipped with a host operation interface lock function; one-touch locking of the control panel effectively prevents accidental touches from causing parameter errors.
6. The receiver includes 4 built-in EQ modes: Bypass, Low-cut, High-cut, and User. In User mode, the 13-band EQ gain can be freely and flexibly adjusted via the receiver panel buttons to suit more application scenarios.
7. The receiver presets 4 groups of interference-avoidance frequencies, effectively improving installation efficiency when multiple systems are used simultaneously.
8. The device supports independent frequency scanning detection for each channel, real-time identification of environmental interference signals, and automatic matching of clean available frequencies. This greatly reduces signal dropouts and noise issues, ensuring more stable multi-system simultaneous use.
9. The microphone panel features a 2.8-inch display screen that shows speaking time, transmission frequency, connection signal, channel, battery level, and other information.
10. It adopts a professional 14 mm gold-plated condenser microphone capsule for sensitive pickup and clear voice reproduction.
11. Equipped with triple speaking status indicators: when a unit starts speaking, the button, gooseneck indicator light, and on-screen icon light up simultaneously, clearly identifying the speaking position from multiple angles.
12. The microphone has a Type-C charging port and supports normal operation while charging.
13. Features a gooseneck microphone connected to the base via a threaded joint, supporting 360-degree rotation adjustment. The overall design is stable, premium, and elegant.
14. The unit uses a 3000 mAh lithium battery, supporting continuous working time for up to 19.8 hours and standby time of up to 88 hours.
15. The microphone unit supports high/low transmission power adjustment, selectable according to actual usage conditions to help extend battery life.
16. The microphone unit allows auto power-off time setting (1–8 hours). After setting, it will automatically power off when not speaking according to the set time, extending battery life and service life.
17. Uses wireless frequency pairing, allowing pairing without needing to aim the microphone unit at the infrared transmission port of receiver.
18. The receiver features: 4 ANT antenna interfaces, 4 independent balanced output interfaces, 1 balanced mixed output interface, 1 × 6.35 mm unbalanced channel mixed output interface, and 1 IR infrared interface.
