The Technics Digital Link interface was introduced by Panasonic at the Internationale Funkausstellung 2014 in Berlin as an integral part of the new "R1 Reference Class" of audio components.

At the same time, Panasonic relaunched the Technics brand itself.

At the moment, only two devices are announced with this interface, the SE-R1 stereo power amplifier and the SU-R1 network audio control player/preamp.

As can be seen on the product images,[2] the Technics Digital Link uses some kind of RJ45-styled connector and therefore most likely twisted pair cables with an unknown set of pairs.

The so called "VR control data" is used to adjust the output volume inside the power amp rather than in the pre-amplifier, which would be the case in analogue setups.
