Totaldac can supply all necessary equipment for the best of hifi + home theater, including the picture, with a real demo of a really finalized system. In this demo room you can watch a full movie if you like, in an optimum environnement.
Here you don't have to imagine what the demo would be if the set-up weaknesses were solved, no, everything is ready, just enjoy the final result before you decide what to buy.
This system is optimized first for stereo hifi. The amplifiers for the subwoofer take the signal from the terminal of the main speakers.
A standard Totaldac stereo system feeds these speakers: stereo DAC + d1-driver preamp + Amp-1 power amp.
The audio part specific to home theater is added to the above stereo system. The home theater audio is based on a home theater preamp which receives the HDMI audio/video signal from a bluray disc or a multimedia video player.
This preamp is very specific because it needs to have digital outputs for the front left/right speakers. The surround output are simply analog outputs.
This way we accept using the internal DACs of this preamp for the surround speakers (and in some cases the subwoofer as well), but we will use a Totaldac DAC for the front left/right speakers.
The Totaldac DAC or streamer receives this digital signal from the home theater preamp and you have just to select this input for home theater use, and select the other input (for example USB) to return in stereo hifi mode.
So the home theater system is completely disconnected in stereo hifi mode.
For the surround speakers, we just use the standard analog outputs from the preamp, feeding the power amplifier which drives the surround speakers. This is just the normal use for this home theater preamp.
It is also possible to use the preamp subwoofer ouput, if needed, to drive a subwoofer which would be dedicated to the home theater.
View of the front of the room, the main speakers are behind the acoustically transparent screen:
View of the front speakers before the screen installation. Of couse it is possible to use smaller speakers.
So we have now a system using a Totaldac DAC for the main speakers instead of the internal DAC of the home theater preamp.
The system keeps the usual functionalities of a home theater preamp, specifically:
-the mix of the center channel to the left and right front speakers. To do that, just indicate to the preamp interface that there is no center speaker.
-the mix of the bass LFE channel to the left and right front speakers. To do that, just indicate to the preamp interface that there is no subwoofer connected the the subwoofer output.
The downmix coax output of a bluray player would not at all do the same thing because:
-the bass LFE channel would not be mixed to the front left/right speakers. So some bass would be missing.
-the night mode (strong compression) would be systematically applied in Dolby Digital mode, strongly limiting the dynamic.
-its volume would not be synchronized to the surround volume
This Totaldac exclusivity is the key point to merge a high end stereo system and a home theater system, for concerts or films, with or without center speaker, with or without surround speakers, with or without subwoofer.
Another possible use: this preamp can also control digital active speakers + a subwoofer like Kii Three or Genelec in stereo hifi use, possibly with streaming functionality, App control, FM radio, turntable input...
