“PurePath Wireless Audio demonstrates TI’s industry-leading expertise in the digital audio and wireless connectivity markets,” said Erling Simensen, marketing manager for wireless audio products at TI. “With this new wireless headset reference design, TI has taken care of all the back-end work, enabling engineers to prototype in less than a day. The CC8530 can stream two stereo streams from a single audio source to multiple receivers. This opens up exciting new uses for wireless headsets and multichannel home audio applications, such as surround sound speaker systems that eliminate the need for wiring throughout the house, and headphones that can easily switch between two audio streams from a single audio system.”

“TI’s PurePath Wireless technology is enabling us to design advanced wireless audio products,” said Robert Wills, president of InterSource OEM Inc. / Claridy Amps, a design house specializing in audio products. “With PurePath Wireless technology, our high-quality designs deliver wireless multipoint audio streaming, enabling audio systems to scale to up to four speakers and ensure two stereo-audio listening zones. “Products like the Sound of Lights wireless speaker have received tremendous interest along with excellent customer feedback, and we look forward to continuing our collaboration with the TI team.”
