Elevating Wireless Performance with RTX Sheerlink
Empowering Artists and Audio Professionals.
About RTX Sheerlink
Sheerlink by RTX sets a standard for wireless performance, empowering artists and audio professionals to create greater experiences through its robust radio technology, high-quality audio, and low latency. It is used by top-tier customers in different ProAudio segments. Sheerlink is being adopted across multiple segments including
- Stage event with multiple instruments and microphones that are wirelessly connected to the mixer/speaker system
- DJ systems requiring easy installation without the hassle of cables and their limitations
- Conference application with multiple transmitters for larger audiences
- Educational applications like schools, universities, etc.
The situation: Challenges in Wireless Audio Transmission
The typical issue with wireless audio is the latency in the audio link when converting from analog to digital and then transmitting through the air and vice versa. Another common problem is the robustness of the radio technology used, as other radios operating in the same frequency band can affect the performance of the radio link.
The solution: Wireless Audio with RTX Sheerlink
The RTX Sheerlink solution is equipped with the RTX Sheersound Codec (Patent WO2018233788), which offers latency as low as approximately 2.5 ms (analog to analog). RTX supports two radio bands: the ISM 2.4 GHz and the DECT 1.9 GHz.
For the ISM band, the Sheerlink solution features RTX's dual diversity technology (Patent WO2020007914) to ensure an extremely robust radio link. This is combined with the RTX protocol to achieve low latency. This solution has consistently outperformed other proprietary solutions in this frequency band.
The DECT version provides a reserved frequency band and a longer range, which is preferable for certain applications as an alternative to the ISM-based solution.
The impact: Enhancing Product Performance
Our customers recognize that the Sheerlink solution is highly suitable for their product designs and applications, choosing it for its high performance. This enables them to develop and provide products with exceptional audio and radio capabilities, which is particularly essential for customers in the ProAudio segment.
