0

Speaker wires

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

0

Dropouts

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, advanced error correction algorithms fix any damaged packets before they reach the speakers and your ears

24/96

Bit/kHz

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.

8

Channels

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 5.1ms 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.

1/1m

Sync rate

With an unparalleled synchronization rate within 1/1,000,000 of a second, WiSA ensures your picture and audio are perfectly synced.

0

Speaker wires

WiSA Discovery transmits and receives audio wirelessly—no speaker wires are needed.

0

Dropouts

WiSA Discovery transmits audio using the 2.4 GHz spectrum of a standard Wi-Fi network using Wi-Fi AES 256-bit encryption. To ensure optimal performance, even when network congestion is high, Discovery minimizes traffic by utilizing advanced error correction algorithms that require audio packets to only be transmitted one time.

16/48

Bit/kHz

WiSA Discovery technology delivers uncompressed, 16-bit audio at a sample rate of 48 kHz, exceeding the sound quality of CDs. This quality standard applies to all four channels of audio, no matter how they're used—for full-range speakers, subwoofers, or Atmos height channels.

4

Channels

WiSA Discovery transmits four channels of 16-bit/48 kHz audio—ideal for expanding the audio capabilities of TVs, adding channels to soundbars, and creating simple solutions that provide immersive audio experiences.

40 ms

Fixed latency

WiSA Discovery features an audio delay rate of only 40 ms (30 ms transport latency) at 48 kHz—so small, 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.

20/1m

Sync rate

With a synchronization rate within 20/1,000,000 of a second, WiSA Discovery ensures your picture and audio are tightly synced.
