New Dirac audio solution for small speakers premiered in ZUK Z1

Uppsala, Sweden - August 12, 2015 - Dirac Power Sound™, Dirac’s latest sound optimization solution for small speakers was unveiled along with the launch of ZUK smartphone Z1 in China.

Due to the limited size of their internal speakers, mobile devices typically suffer from low output levels, weak bass and an unnatural and unpleasant overall sound. Dirac Power Sound is a combination of technologies designed to improve the sound quality from small speakers for mobile devices such as smartphones, tablets and portable speakers. By addressing the innate imperfections in small speakers, the solution maximizes the potential of a small transducer to reproduce the best sound quality possible at the highest volume with minimum distortion. The results are much louder sound and more impressive bass with astonishing detail and clarity.

The solution’s key technologies like frequency response correction, impulse response correction and bass optimization have been used by Dirac in premium automobiles and HiFi markets for years. Additional advantages of Dirac Power Sound are that it optimizes bass response and volume depending on playback and signal level. Through dynamic high-precision processing, the algorithm continuously adapts to the music in order to fully leverage the speaker’s potential.


ZUK Z1, the first smartphone model by ZUK, is the first product powered by Dirac Power Sound. Chinese startup ZUK, backed by Lenovo, is expected to be a game-changer in the China smartphone market. ZUK Z1 is designed with 5.5” screen, metal central frame, top level HW configuration and clean, easy-to-use ZUI OS. It features only one button named U-Touch. Designed for heavy smartphone users, ZUK Z1 is composed with fingerprint sensor, Qualcomm Snapdragon 801, 64GB eMMC storage, 4100mAh battery and USB 3.0 Type-C. The handset is priced at RMB 1799 and will go on sale in China on August 18th. The international version is expected to be released soon.
