The WiSA standard for wireless transmission of audio does not really want to gain a foothold yet. A small number of audio manufacturers, including Bang & Olufsen and Harman, use the standard and in the field of television, LG provides its top models with the standard. To make WiSA more widely usable, the organization behind the standard is now introducing the SoundSend box.
The SoundSend box is a small device that allows you to send the audio from your (non-WiSA) television wirelessly to WiSA-compatible speakers. The box is connected to the HDMI-ARC port or the optical port of your television, after which the audio is sent to linked speakers in the room. The standard is supported by products from Bang & Olufsen, Harman, Klipsch, Savant, Dynaudio and Enclave Audio, among others.
The $ 179 SoundSend supports audio up to 24bit / 96kHz with up to eight channels in Dolby Digital or Dolby Digital Plus format. The compact box can also handle Dolby Atmos signals (not lossless), but DTS is unfortunately not supported. Installation and operation must be simple, using an app for your smartphone. The app offers the possibility to calibrate each paired speaker based on the listening position using the My Zone function. This is how the optimal sweet spot is created. WiSA itself does not need a WiFi connection as the standard works on its own frequency.
