I don't own any Theta gear but I thought you would need the Six Shooter specifically for this purpose.

Need the six shooter for 6-channel analog in. That's only possible if you have the digital out card in your 'Nova. I have not seen many 'Novas with this configuration. Stock Casanova analog input card converts all incoming 2 channel analog signals to digital. However, using SPDIF coax or toslink, you can decode Blu-Ray discs with Dolby TrueHD @640kbs and DTS/Master Audio @1,500kbs. This is an audible sonic upgrade over DVD in which maximum for Dolby Digital 5.1 is 440kbs and half-bitrate DTS (most DTS DVDs are encoded with 740kbs DTS rather than the original DTS Core of 1500kbs). In conclusion, home theatre sound on your Casanova with Bluray discs is audibly superior to Standard DVD with the digital coax or toslink connection.
I am not sure I understand the question and above replies. I believe (correct me if I am wrong) Jaidog will be using a Blu-ray player (DVD players can't decode Dolby TrueHD or DTS-HD Master Audio) and have the Blu-ray player pass the decoded 5.1, or 7.1, signal to his Theta Casanova processor (which cant handle Dolby TrueHD or DTS-HD Master Audio via HDMI). Is this correct? So, you want to know how to get the Casanova to handle the 5.1 or 7.1 decoded analog channels?
If I have got this right, I will be very interested to see what the board members have to say about this task. I have exactly the same problem with my Pioneer Elite Blu-ray player (which can decode Dolby TrueHD and DTS-HD Master Audio to analog) and Krell HTS 7.1 which cant do the decoding, but, can handle a 5.1 or 7.1 analog input.
Krell HTS 7.1 has 7.1 analog inputs, Theta Casanova doesn't. Instead, Theta user needs an additional unit called Six Shooter which accepts 5.1 (in this case) analog inputs and then interphases with the original CasaNova.
What Jimburger is saying is that the stripped down audio signal (i.e., lossy) from a BluRay player are of higher quality than that from the good old DVD player so it would still be an improvement feeding the same prepro with coax/toslink input from a BluRay player.
I have the Krell HTS 7.1 as well. For lossless audio, I am using the Oppo BDp-83 analog outputs to the Krell. All the speaker distance, volume trims etc. are done on the player.
Thanks to everyone for their advice. I was not aware
that the signal over the coax/toslink is better from
a blu-ray player than a standard dvd player. Based on
this info, I will attempt to use this interface from
my oppo bdp-80 (not yet purchased) to CasaNova.
Follow-up question: Does the Krell HTS 5.1 have 5.1
analog inputs that would allow lossless audio from
a blu-ray player? And, how does the HTS 5.1 compare
with the CasaNova for both HT and 2-channel sound?
