WiSA Association Announces Wireless Soundbar System Reference Design

Sunnyvale, CA, August 29, 2012 – The Wireless Speaker and Audio (WiSA™) Association today announced the availability of a WiSA-compliant wireless soundbar system reference design. The reference design is available to all WiSA Association members and is compliant with the current version of the WiSA Compliance Test Specification (CTS). The WiSA CTS is the industry's first compliance test specification that outlines an interoperability testing and certification program aimed at products that offer wireless, interference-free, uncompressed HD audio taking advantage of the unique 5GHz Unlicensed National Information Infrastructure (U-NII) frequency band.

The soundbar reference design is architected to ensure interoperability between WiSA-enabled components and to address the minimum requirements for basic system performance (i.e. volume tracking, audio latency, network setup, audio channel assignment, and scalability, etc.) independent of price point and product component attributes.

"Our members have been asking for a soundbar reference design to accelerate their WiSA-enabled product introductions and save months in development time and costs," said Jim Venable, president of the WiSA Association. "Having immediate access to development and design tools that define HD wireless audio transmission is one of the key benefits of WiSA membership, along with participating in and being aware of the future direction of the wireless audio and speaker industry being led by the Association."

Design files for the reference design are provided free to WiSA Association members, and include the following:

  • Application processor and audio DSP board design
  • HDMI® module design
  • Front panel board design
  • Remote control board design
  • 2x25W soundbar amplifier module design (for wired front speakers)
  • Speaker electronics design (amplifier, power supply)

Additionally, a fully implemented soundbar reference design hardware kit may be purchased from Summit Semiconductor, a WiSA Association Advisory Board member, along with optional wireless speaker amplifier modules for surround and subwoofer applications.
