ZONE2-PRO 8K eARC Audio Processor


  • HDMI Audio and eARC transmitter output ports

  • Two HDMI 2.1 48Gbps FRL6 inputs with CEC control

  • TRACKSYNC volume control between displays

The flagship Zone2-Pro is a THENAUDIO dual-output eARC audio processor that also functions as an advanced HDMI 2.1, 8K, 48 Gbps (FRL 6) CEC-controlled A/V switcher through its onboard version of a limited GUIDE switch. Able to distribute eARC audio simultaneously to two separate audio systems, the Zone2-Pro maintains matched volume output levels through TRACKSYNC. This proprietary algorithm overcomes interoperability issues for connected devices inherent in the CEC specification. 

One example is an eARC signal directed from a TV to a soundbar. With the Zone2-Pro inserted into this signal path, eARC audio data is decoded and then re-encoded with THENAUDIO metadata designed to optimize the interface with compatible legacy audio processors that lack a formal eARC-designated input. Splitting the signal path into two, one path carries on to the soundbar, and the second is extracted for connection to a lossless format-compatible legacy AVR. (Note: Audio is extracted and remains in its digital multi-channel codec form; it is NOT downmixed or converted into analog stereo for distributed multi-zone use). Video content passes through unaltered and is not decoded.

Two HDMI 2.1 HDMI 8K, 48 Gbps inputs accommodate post-18 Gbps media consoles with bandwidth headroom for the latest 4K/120 fps HDR games up to 8K/ 60 fps, 4:4:4 color space. Unique CEC port switching enables respective device remote controls to activate input switching on a TV or projector to finally deliver on the promise of CEC control that has seldom functioned with sustained repeatability.
