Ideal for diverse scenarios ranging from home entertainment and personal performances to commercial events and conference rooms.


Functional Features

User-Friendly Operation

The system features an intuitive operation logic, allowing users to quickly set up and use it without the need for professional technical assistance. This significantly reduces the complexity of system configuration while catering to needs such as home entertainment and personal performances.

High Compatibility

With an ultra-wide bandwidth of 64MHz—broader than most comparable products on the market—the system supports simultaneous operation of up to 24 compatible units within this spectrum. This enables efficient utilization of frequency resources and provides ample frequency options even for large-scale events, making it easier to avoid interference.

High-Definition Audio

Combining core hardware with anti-interference technology, the system delivers pure and accurate sound reproduction. Equipped with a high-performance processing chip and Relacart's proprietary anti-interference technology, it covers a wide frequency response range of 30Hz–20kHz. This ensures precise capture of vocal details across all ranges, from deep resonances to high-pitched nuances, reproducing transparent and crystal-clear high-fidelity audio.

Stability and Reliability

The system offers an effective operating range of up to 100 meters in open environments. Even in large venues such as conference halls or outdoor performance spaces, it guarantees stable audio transmission without quality degradation or signal loss over long distances.

Strong Anti-Interference Capability

Utilizing Relacart’s digital wireless technology integrated with diversity and anti-interference mechanisms, the system enhances signal stability at the transmission level. It ensures continuous, uninterrupted audio even in complex environments, providing a reliable experience for prolonged events and meetings.
