    What does 48k mean?

    When playing the source from my dvd player I get 48k on the front panel and with any sound mode selected. It is connected via coax.

    What does 48k mean?

    It's the bitrate of the digital signal being sent from the dvd player into your processor/receiver. PCM can be 44.1, 48, or 96.

    Is your dvd player set up to send Dolby Digital and/or DTS bitstreams unaltered to your receiver? You may want to check.

      Somewhat related to this, is it possible to get a Dish PVR model 921 (or any other satellite receiver) to spit out anything other than a 48K PCM bitstream? If so, what configuration should I be looking for in the setup menu? I would very much like to listen to the audio only satellite channels in 44.1K. It seems to me there is better imaging when I play my regular CDs through the Rotel (which shows the 44.1K sampling rate) when the sound is sampled at 44.1K versus the same music played through a satellite radio station like sirius. Thanks.

        The Dish can only output 48khz, but thats not the difference that makes CD's sound better. It's the fact that CD's just sound better. Sirrius sounds bad enough through a Sirius tuner, it's killed by the time it goes through the compression Dish puts on it.

          Ditto on what Kevin said. I use to have XMRadio, and I can tell you that most of the sound is compressed, probably to save on bandwidth. It would seem their philosophy is quantity over quality. Unfortunatey, high end audio people such as ourselves probably make up a very small percentage of their subscribers, so I'd not expect any changes soon.

          However, I am curious to see what Rotel accomplishes (if anything's possible) with their upcoming Sirius/FM tuner.

            That makes sense, Kevin. Thanks. Do you happen to know what compression scheme Dish uses to wreck, I mean deliver, the audio channels?

            Are any other satellite-based or internet-based content providers sending out uncompressed or lossless audio?

            Maybe I should just buy or build an HTPC/audio server...

              I believe they use Dolby Digital for their audio compression.

                RSP-1068 & PCM Stereo 24/96
                by chanlon
                Hello,

                Just received the Neil Young Live at the Filmore DVD/CD Set for Christmas.
                The DVD outputs at PCM Stereo 24/96. I was wondering if the Rotel Processor supports this?

                I have PCM Stereo 24/96 selected on the DVD player and its connected via a Digital cable....

                Satellite Radio (XM and Sirius)
                by Chris D
                I'm curious who has experienced satellite radio, and what comments you could make. Obvious attractions for using it would be national radio reception, diverse programming, and perhaps portable capability.

                But how does it SOUND, man, how does it SOUND? From what I understand, the audio...

                Chroma Bug on Hughes E86 satellite receiver?
                by Chris D
                I bought a Hughes E86 HDTV Satellite Receiver from Good Guys a few weeks ago. They're having a sale on them for $399, brought down even further to $299 if you buy any HDTV.

                So far the set has been great. Others have reported local channel reception being dropped by these units, but I...

                VOOM Satellite is busting loose!
                by Sonnie Parker
                Voom is really makin' some noise in the satellite world. Especially in the HD area as they are now up to 37 HD channels (21 of those exclusive to VOOM) and have more on the way in June.

                We've posted a little on this in the past but they haven't had much offering up until recently....
