Wireless Wisdom means superb audio performance

ProAudio

The professional audio industry is constantly searching for robust wireless transmission links that can transfer high-resolution audio signals at super-low latency. Recent frequency regulations have driven professional systems towards digital modulation schemes and open ISM bands putting them in competition for spectrum against widely used technologies and applications such as Wi-Fi and Bluetooth®. To develop high-performance systems that can deliver perfect sound in these environments, you need Wireless Wisdom.

With years of experience in ProAudio design, development and manufacturing, RTX has gained the expertise to deliver incredible sound quality in high-density RF environments whether they are in the home, the studio or challenging radio environments having high inter-symbol interference.

If you need ProAudio having low latency, robust links for difficult radio environments, spectrum-efficient high audio quality, long radio range and/or low-power consumption – we have the expertise you need. We have already created customized ProAudio transmission systems for many of the world’s leading brands. We can help you too.
