As we can see from this scan the addition of the XLR digital outs is no afterthought, being well integrated into the back panel. Tact must be aware of the HDMI rules so one would think they have a plan in mind but it is hard to imagine what it could be.
Perhaps to use the Tact processor you are going to have to use Tact amplifiers with the de-encryption occuring in the amplifiers. Thus, you would have encrypted digital out of the processor and analog output from the amplifiers.

Here is a quote from the current description of their digital theater:

"TCS mkII and S-2150 digital power amplifiers can be used in a 7.3 all digital home theater configuration. AC3/DTs digital bit stream is connected to one of TCS mkII digital inputs. TCS mkII performs all surround sound decoding, base management, room correction, level balancing, time alignment on all ten channels. TCS mkII digital outputs are connected to corresponding S-2150 digital inputs. S-2150 is a true digital power amplifier (not a hybrid) that operates in digital domain and converts digital signal to analog directly at the loudspeaker posts."

It would seem a simple step to put the de-encryption in the amplifiers. This is not unlike Meridian's model, except that Meridian takes the further step of integrating the actual speakers themselves in the package.
