Deliver stunning multichannel sound wirelessly, without compromise.

When it comes to wireless home theater, stunning quality, remarkable precision, and lightning-fast sync are key. Featuring up to eight channels of HD audio, WiSA Home Theater Technology transmits and receives uncompressed 24-bit 48/96 kHz sound over a dedicated wireless network it creates, all with no perceivable latency. WiSA also makes it easy for consumers to set up their cinema sound systems—simply power-up the components and WiSA does the rest.

Make great connections.

All WiSA Home Theater (HT)-certified components—independent of brand—work together seamlessly.

Speaker wires

With WiSA technology, sound systems can transmit and receive audio wirelessly—no speaker wires needed.


GHz spectrum

WiSA technology uses the U-NII 5 GHz spectrum to transmit audio. Free from congestion, this spectrum sports 24 RF channels—all monitored continuously. As a result, if RF interference is detected on the channel in use, audio is switched to another channel before the signal is disrupted ensuring you never miss a beat. In addition, our advanced error-correction algorithms ensure only high-fidelity audio reaches your ears.



WiSA technology delivers uncompressed, 24-bit audio at a sample rate of 96 kHz (CDs are 16-bit, 44.1 kHz, for comparison). Because a higher bit rate supports a wider dynamic range, sound systems with WiSA technology deliver remarkably rich sound, greatly enhancing your entertainment experience.



WiSA transmits up to eight channels of 24-bit/96 kHz audio, supporting sound systems up to 7.1 and 5.1.2 Dolby Atmos for truly immersive audio. Listeners experience movies, TV, music, and games the way they're mastered—with sounds that originate in different parts of the room and move around you.

2.6 ms

Fixed latency

WiSA boasts an audio delay rate of only 2.6 ms at 96 kHz and 5.2 ms at 48 kHz—so minuscule, it's undetectable. Best of all, the delay is fixed and cannot be impacted by the number of audio channels transmitted, the distance between the audio transmitter and speakers, or by RF interference.

±2 µs


With an unparalleled synchronization time of ±2 µs, WiSA ensures sound from every speaker is perfectly synced.
