Cut the cord on your pro-audio product

RTX can support your product realization from product concept to mass production. RTX has completed more than 1.000 projects during its 30 years of history, from initial development, desired design, test and approvals and final production. This ensures a proofed solution, that high-end professional audio brands demand.

Sheerlink proposes a unique wireless solution

Plenty claim to have cut the cord on pro-audio, but very few have succeeded. Often poor antenna quality creates drop-outs due to product design requirements, or poorly developed codecs fail authentic stage tests. Our Sheerlink product solution provides excellent audio quality, low latency, resilient wireless link with extremely low interference issues, adaptive radio with intelligent interference avoidance, multiple connection models and is easy-to-integrate.

RTX Sheerlink Specifications

Designing a wireless standard

Minimal latency

Timing is everything for the perfect live performance, which makes latency the audio industry's worst enemy. Sheerlink gives extreme low-latency. Less than 2ms depending on the configuration.


Zero interference

With intelligent radio drivers and optionally using reserved radio bands, Sheerlink eliminates drop-outs and creates hyper-smooth audio delivery. A resilient wireless link bridges instruments or microphones and receivers with a lightning-fast connection with quality, unique in the industry.

Zero wires

The music industry is dominated by cables due to the fear of latency, dropouts, and generally poor audio quality. Sheerlink provides a professional wireless audio standard that provides an exceptional sound experience.


Maximum freedom

Technology-enhanced connections ensure the artistic freedom of the performer while providing ease of installation for supporting sound technicians.
