High-performance speakers

The challenge

Our client, Q Acoustics, is known for its innovative, high-performance loudspeakers. In the final development phase of their Q Active wireless audio system they required additional expertise to support the project from both performance and compliance perspectives.

Our solution

The Q Active system can be connected to a number of wired and wireless audio sources – turntable, hard drive, television, gaming console, smartphone and more. The company takes an uncompromising approach to quality, so this project was about optimising the hi-fi sound from every source. Red Horizon was asked to help to refine audio quality, RF performance, debug a few minor issues and confirm that real world performance met specified requirements.

We developed techniques to analyse digital audio at every node of the signal path to isolate problem areas. When a subtle audio quality issue was determined as being the incorrect configuration of an IC in the signal chain, we recommended the correct register configuration values.

Our input took the system from the final development phase to the point of release to manufacturing. We also ensured the units would comply with testing and certification requirements for worldwide markets.
