SW-2000M Dual-System Digital Conference Host

SW-2000M Dual-System Digital Conference Host

Core digital technology with a built-in high-performance CPU delivers clear audio across the full 20Hz–20kHz frequency range.

Features anti-interference circuitry to eliminate mobile signal disruption, while a high-performance switching power supply ensures uncompromised audio quality over long distances.

Integrated wireless communication chips enhance transmission range and stability, adapting to specialized conference environments.

The conference host supports hybrid wired + UHF wireless handheld microphone connections, with 8 reserved input ports (each supporting 40 units). Capacity can be expanded via extenders, allowing up to 168 wireless microphones to be online simultaneously;

Equipped with 2 UHF pickup antennas, 1 433MHz control antenna, and an external suction cup antenna. The 433MHz antenna supports signal extension via an amplifier, eliminating complex wiring for flexible venue setup.

Supports simultaneous operation of multiple systems (with 20 preset frequency channels), allowing wireless microphones to be added anytime without reprogramming.

2.8-inch color display + 6-button hierarchical menu; supports USB recording backup; features intelligent functions including central control, one-touch shutdown of all units, and automatic microphone power-off (2 seconds after host power loss);

Offers 5 meeting modes (Chairman-only, First-in-First-out, etc.), configurable speaker count (1-12 persons, except in All-Open mode), and supports wireless/wired Chairman units to mute all delegates;

Comprehensive interfaces (including PC debugging USB, camera tracking, RS232 central control interface, etc.), supports multi-channel volume adjustment and camera tracking debugging, suitable for diverse scenarios like meeting recording and remote control.
