LR2000 True diversity one by one hand-held wireless microphone

The LR2000 spectrum intelligent control can precisely capture every detail, and all data can be operated and monitored. The intelligent frequency band superposition technology has 200 available frequency points within a 50MHz bandwidth, meaning that 8 hosts can be installed in the same cabinet for use and 20 sets can be superimposed simultaneously. The system integrates automatic idle channel selection and infrared data synchronization. This system is suitable for any large-scale performance or public broadcasting environment with strict requirements.

1. The automatic tracking and tuning technology ensures that the system maintains the best selectivity when operating at any frequency, solving the co-frequency interference, adjacent frequency interference and intermodulation interference in the performance venue.
2. Built-in intelligent audio processing engine: adaptive noise reduction, dynamic EQ adjustment, etc.
3. It is equipped with a high-precision spectrum analyzer to accurately identify hidden interferes (such as weak intermodulation products) in wireless systems.
4. Transmission power: Dynamically adjust the transmission power and frequency group to balance the coverage range and power consumption.
5. Preset Frequency Group: For multi-hall conference rooms or large-scale performances, load the preset frequency group to prevent signal crosstalk across halls. Pre-allocate non-overlapping frequency bands to prevent cross-frequency interference among multiple microphones or with external signals (such as WiFi, Bluetooth, etc.). When the main frequency band is interfered with, the clean frequency band of the preset frequency group is activated to ensure continuous communication
6. High-brightness LCD dot matrix liquid crystal display, clear and comprehensive working status, touch-sensitive digital volume and noise reduction control system, easy to set and operate.
7. Modular microphone head design, easy to replace; Two optional RF power adjustments: 10MW/30MW
8. Infrared data synchronization function: The LCD screen uses a white backlight to indicate information such as group number, channel, battery life, and lock status.
9. Customize device labels to replace the traditional fixed sticker serial numbers.
10. There is no switch impact sound, ensuring the safety of the power amplifier and speakers at the rear stage.
11. It adopts a 1U metal chassis, featuring a sturdy structure, excellent professional quality in heat dissipation and harmonic interference isolation, making engineering installation more convenient.
12. It features independent balanced (XLR Shannon) output and unbalanced (6.3mm socket) hybrid output, with a rich variety of interfaces to meet the needs of various devices.
