Why cant it pass the signal from an internal Blu Ray decoder?
02-09-09: Richard_stacyI did that, though I found the back panel diagram on page 7. At any rate, there is no multi-channel analog input and no HDMI input, so there's no way to get a lossless surround signal from a Blu-ray player into your Casablanca.
if you go to theta's site and library, product manuals, casanova, owners manual pdf page 16 shows the exact rear panel layout i have.
To illustrate what I'm talking about, look at the back panel of an Outlaw 990 AV Pre/pro here. Just to the right of the eight XLR inputs are two sets of color-coded RCA jacks, delineated by two white rectangles. The upper rectangle has 9 RCAs and is labeled "PREAmp Out," Your Casanova has an equivalent 5.1 channel output that's sent on to your amplifier(s).
The lower rectangle has 8 RCAs and is labeled at the bottom, "7.1 AUDIO IN." The 8 jacks are L, C, R, LS, RS, LRS, RRS, and Subwoofer. This 7.1 "Audio In" grouping (or at least a 5.1 Audio In grouping as many pre/pros and AV receivers have) is what you need at a bare minimum to get the lossless surround signals off an appropriately equipped Blu-ray player.
I have a Boston Acoustics AVP7, which is based on the same pre/pro as this Outlaw, and I use its 7.1 analog inputs this way to extract an uncompressed 5.1 surround signal from my SACD/DVD-A player with internal decoding. When used this way, the pre/pro simply functions as an 8-channel line stage.
