  • Re: Multichannel listening

    Hi, I believe that the problem is one of sampling rates. The Beosystem 4 / Beoplay V1 / Beovision 11 etc. are incompatible with LPCM on HDMI at 88.2 or 176.4 kHz. This means that you have to find a disc player that can convert the multichannel SACD layer to LPCM at either 44.1 kHz or at 48/96/192 kHz. Many players will convert DSD to 88.2 or 176.4 since this is an easy decimation. Sometimes, the player will give the option to set a maximum sampling rate to 44.1 kHz. Some other players will give you

    [quote user="Sandyb"] Indeed, and another way of looking at it is this - why make a speaker capable of higher rates if those higher rates make no difference? [/quote] There are advantages and disadvantages of using higher sampling rates - neither of which is terribly simple to explain in a couple of sentences. However, the usual excuses of "temporal resolution" (which is just wrong) and "bandwidth to include inaudible frequencies" (which has been proven repeatedly to

  • Re: Feed your Beolab 50 and 90?

    Just a quick follow-up on the stuff I wrote about de-emphasis filters back a couple of weeks ago. I've been digging into vinyl playback a little more than usual of late, for reasons both personal and professional (as you can probably guess). As I told someone recently, I'm old enough that my textbooks talk about mastering for vinyl, but I'm young enough that we skipped those chapters, since vinyl was on its way out in those days. So, I happened to have a library of information that I've

  • Re: Beolab 50 installation manual?

    I said CAT6 is recommended for the connection from the Primary to the Secondary loudspeaker. I said Wires are better than Wireless for the audio signal to the Primary loudspeaker (I use Power Link from the TV, and then S/PDIF and XLR to the Oppo (S/PDIF For PCM, XLR for DSD), Optical and USB Audio for experimentation, and RCA to a turntable (via a RIAA preamp). Cheers -geoff

  • Re: Beolab 50 installation manual?

    Maybe I can help here with a couple of points by compiling some already-public information into a small set of bullet points to suit the discussion.... Wireless Power Link like any wireless audio system, will have errors caused by signal interference in the RF domain. Since it's a very low-latency system, there's no possibility of a re-transmission of data, so it uses an error concealment system. This works very well - but it does mean that the system is not perfect (nothing is perfect..

  • Re: Beovision Eclipse sound settings

    [quote user="thorne"] So my question is, why is there a speaker group section in the general sound menu, when you use the source menu to choose the appropriate speaker group? [/quote] You can set a default Speaker Group (and Sound Mode) for a Source so that it is not necessary to manually choose both each time you start the television or change sources. The "Speaker Group" menu is primarily designed for customising the parameters of each Speaker Group. However, you can use that

    [quote user="Sandyb"]I wont ask for comment re quality, as my guess is that its not something you have played with. [/quote] Hi, I never make any comment or recommendations on any audio equipment that I have not personally tested... HOWEVER, I should like to point out that, when looking at streaming devices, you can't just consider the end-device (in this discussion, the player). You also have to consider the interaction between it and your network, the software running inside your

  • Re: Feed your Beolab 50 and 90?

    [quote user="Mikipidia"]Side note question, what makes a good RIAA? I though it was all a standard they had to follow?! How can you tell which one is good/better/best? [/quote] RIAA is just a specification of a filter curve - so it's a measure of the magnitude response (what most people call the "frequency response") of the preamp - the gain of the preamp as a function of frequency at one input level. However, this is only one measure of a preamp - and, more importantly, it's

    Oppo 105 connected as follows: -> HDMI -> Beovision 11 -> Power Link to Beolab 90s for anything with video or in surround -> S/PDIF - > Beolab 90s for all 2.0 PCM playback up to 192 kHz -> XLR -> Beolab 90s for DSD materials (2.0 SACD and DSD files) I've got the 90s with the inputs prioritised in the order listed above, That way they automatically select the S/PDIF input over the XLR when I'm playing PCM materials, and the Power Link wins when I turn on the TV. No, the
