Better than unidirectional soundbars, Platin leverages WiSA SoundSend to provide Monaco plug and play multichannel Smart Speakers to millions of home cinemas

SAN JOSE, Calif. (October 27, 2020) — WiSA® LLC, founded by Summit Wireless Technologies (NASDAQ:
WISA), today announced the launch of a wireless home cinema bundle complete with the WISA
SoundSend transmitter, the Association’s first branded product, and the Tuned by THX™ Monaco 5.1
Immersive Wireless Home Audio System™ from Platin. The bundle will be available for purchase in
November 2020 via Amazon for $899, and pre-orders can be placed at Platin Audio’s site.

“The Association is excited that the WiSA Certified™ Monaco 5.1 system, a complete surround sound
solution, will be the first to be bundled with the new WiSA SoundSend transmitter” said Tony Ostrom,
President of WiSA. “With the help of the SoundSend, the home theater bundle offers 5.1 high-resolution
audio and is also capable of virtual Dolby Atmos performance. The entire system can be set up in
minutes to create a cinema in your home. The bundle will entice audio enthusiasts and novices alike
with its wireless capabilities and uncomplicated installation process.”

The Monaco 5.1 with WiSA SoundSend system gives users immersive, theater-quality experiences
made possible by WiSA Certified speakers and the HDMI (or optical)-connected transmitter, allowing for
effortless home cinema setup and control in less than ten minutes. The SoundSend transmitter, WiSA’s
first branded product, is a universal wireless multichannel home cinema audio transmitter designed to
enable simple, yet amazing, home entertainment experiences for owners of smart TVs. The transmitter
easily connects via HDMI/ARC and eARC to hundreds of millions of new and installed smart TVs. Better
than unidirectional soundbars, the Platin Monaco and WiSA SoundSend system allows consumers to
easily create truly immersive home cinema experiences in minutes.

The compact Monaco 5.1 system from Platin is Tuned by THX™ and perfectly combines high-definition
audio quality and a less than 5.2 millisecond latency for picture-perfect lip sync. With only a 1
microsecond synchronization between speakers, the result is amazing accuracy and clarity. The system
fits easily into any size living space–no audio cables required–and users can connect the speakers to any
AC outlet. WiSA SoundSend decodes Dolby Digital, Dolby Digital +, Dolby TrueHD and Dolby Atmos and
offers audio quality of up to 24bit/96kHz. The SoundSend and Monaco combination can also create
virtual Dolby Atmos experiences when an Atmos signal is delivered to SoundSend.
