Here is the wireless technology you've been looking for

WiSA is intended to massively simplify music systems by doing away with speaker wires.

There was a time when being an audio enthusiast meant living with wires. Lots and lots of wires. That was the price you had to pay for quality audio, especially if you wanted a home theater system with true surround sound. Well, if WiSA (Wireless Speaker & Audio Association) has its way with your next music system could be virtually wire free.Well, except for the wires in your power cables.

Why you might want WiSA

For starters, WiSA systems supports up to eight channels of uncompressed 24-bit audio. It’s super-easy to set up, and it eliminates cable connections between components, leaving only the power cables to worry about.WiSA delivers super-low latency, too—latency being the time it takes for an audio signal to travel from a source to emanate from the speaker.

I’m not talking the 40-millisecond delay that’s considered low by the Bluetooth folks, but a mere 2.6ms at 96kHz sample rates (5.1ms at 48kHz), which is imperceptible to humans.

That means little to no compensation is required on the part of a TV or other audio device to keep audio in sync with dialog and on-screen action. That’s as great for watching movies as it is for playing video games on an Xbox or PlayStation.

What is exactly WiSA?

WiSA is an audio technology that establishes a discrete wireless local network exclusive to WiSA audio sources (TVs, receivers, video-game consoles, etc.) and destinations (speakers). It steers clear of with your Wi-Fi router and privately uses less-populated 5GHz frequency bands (with 24 RF channels available in the 5.1- to 5.8GHz spectrum) along with various techniques such as spread spectrum, error correction, and dynamic frequency hopping to avoid interference and maintain signal strength.

WiSA has a 25 meter range and supports 24-bit resolution with sampling rates of 44.1-, 48- and 96kHz without any compression or conversion.
It can handle other sample rates by up- or down-sampling the material if the playback device doesn’t handle that natively.

If you’re not familiar, the CD standard is 44,100, 16-bit samples per second, which delivers a noise floor that’s low enough that most users won’t hear digital noise, and a sampling rate that’s fast enough to capture and play back frequencies up to 22.05kHz—that’s well beyond the range humans can hear.

Supporting 24 bits delivers an even lower noise floor, and a 48kHz sampling rate takes care of supposed golden ears.

A 96kHz sampling rate is overkill in terms of capturing or reproducing frequencies (it can represent up to 48kHz waves): There’s hardly any recording equipment that will capture frequencies above 20kHz, and no listening equipment—i.e., your ears—that can hear it.

The higher sampling rate, however, does allow faster processing and gives you the lower 2.6ms latency I mentioned earlier.

Uncompressed audio

WiSA technology delivers audio directly to the speakers just as it was mastered in the studio – ​24 bit audio up to  96 kHz.  No compression, no compromise.

No drop outs

WiSA operates across the uncongested U-NII 5 GHz spectrum with up to 24 RF channels available. Compare that to only 3 non-overlapping channels in 2.4 GHz and 5 channels in 5.8 GHz.  More is always better.

Scalability built in

WiSA is designed to be easily scaled.  Start off with a stereo speaker system and at a later date add more speakers to upgrade your system to a 2.1, 3.1 or even 7.1 system.

Multi-channel goodness

8 channels of 24 bit high resolution audio (up to 96 kHz sample rates) are transmitted, supporting surround sound systems up to 7.1.

Better than CD quality

CD quality is 16-bit, 44.1 kHz.WiSA technology supports 24 bit, 96 kHz across all 8 channels, which means it can transmit Blu-ray movie audio exactly as it was mastered in Dolby Atmos, TrueHD or DTS-HD Master Audio.   But if CD quality is good enough for you, no problem – it can do that too.

DFS - Dynamic Frequency Selection

The WiSA system is constantly monitoring for clear channels.  When RF interference is detected, the system seamlessly switches to a  channel before you experience audio disruptions.  The transmitter coordinates with all the speakers to simultaneously jump in between audio samples without the listener hearing a thing.

Simple to set up

With WiSA you can have a music system up and running in under 30 minutes (including unpacking).  It is as simple as plugging in power, setting the speaker type at the speaker and pushing a button.
