It's no news to anyone that uses our products that they must be connected by... wires. We're aware of this of course, but it's a necessary part of our innovative product range that provides advanced DSP for home, studio and car audio – subwoofer integration, tonal adjustment, and advanced room correction.

Until now.

With modern wireless technology making strides into high-resolution lossless audio transmission, miniDSP has started incorporating this technology into our product range. Our compact 8-channel Flex Eight audio processor now has an optional upgrade purchase for an eight-channel wireless transmitter using a technology known as WiSA.

About WiSA [Top]

WiSA ("Wireless Speaker and Audio Association") is a set of standards for wireless audio transmission over short distances (as in, within your listening room). WiSA is specifically designed for realtime audio – this means that there is a very low latency (transmission delay) as low as 2.6 ms. What's more, the latency difference between speakers is very low indeed – less than two microseconds – ensuring that there are no issues with soundstaging or timing between speakers.

The version of the WiSA standard that we've adopted runs eight channels of 24-bit audio, at either 48 or 96 kHz. This is a perfect match for the Flex Eight, which has eight output channels at 96 kHz (standard version) or 48 kHz (Dirac Live version).

With the Flex Eight upgraded with WiSA, you can transmit high-resolution audio seamlessly and losslessly to up to eight WiSA speakers. The speakers can be any WiSA-compliant speaker, including subwoofers. An increasing number of speaker manufacturers support WiSA, including Klipsch, Buchardt, and B&O.

For a more complete list of WiSA-compliant speakers, see https://www.wisatechnologies.com/speakers.

Example: Using Dirac Live with WiSA [Top]

With the Flex Eight with WiSA, you can now combine wireless audio transmission with Dirac Live room correction. The following diagram illustrates a typical system configuration using the miniDSP Flex Eight with WiSA speakers and subwoofer.

Wrapping up [Top]

Of course, it's early days yet, but we're excited about growing the miniDSP product range with this rapidly advancing technology. Please feel free to share your experiences with miniDSP and WiSA in our community forum. For more about WiSA, see the WiSA website.
