Knoll claims the audio signal from the WTA-PACK "No-Wire" audio system can travel through most walls and is reliable for up to either 30m (indoors) or 45m (outdoor line of sight).

It uses so-called "Klean Audio Technology" (KAT) and features an analog input, digital transmitter paired with a unique easy to position 25W per channel receiver-amplifier.

The system also offers a line level receiver for instances where amplification is already available.

In addition to audio-only, Knoll also has an HDMI version.
