    Hi All,

    I was looking forward to watching For a Few Dollars More again last night through my 'new' 5.1 setup, but the sound was only coming out of the centre speaker .. my mate did laff ... :-/

    Now I know the film is recorded is dolby digital mono, but hey the TV spews this out of both speakers, so why cant lexicon DC-1 at least do the same?!

    I tried cycling through all the effect modes, but no change. I even tried disabling the centre speaker, but still the same.

    Am I missing something obvious? Or can the DC-1 not handle :dd:Mono?:eek: !

    Thanks,
    B.

    Hi,
    Can you give us the settings on the 'DVD INPUT Config' screen? To get there go to setup-input - config - dvd.
    You can play it it in 2-channel stereo mode or other modes as well. Were you playing in Logic-7 mode?

    Hi bbanduser,

    The velodyne is working great :D still trying to find best settings. But fills room nicely.

    Here's settings while watching the DVD - the effect reads 2.0 Logic 7 and its detected AC-3 as the audio type.

    Gain OFF
    PCMFX LOGIC 7
    AC3 FX 5.1 Logic 7
    DTS FX DTS Logic 7
    FX Format Auto
    Audio In Coax-1
    Video In DVD
    Rec/Zone 2 Analog
    Trigger Enable

    I can hear 99% out of the centre and the fronts just about 1% which sounds lie its some bass thumps here and there. Fronts are set to large and centre to small cut off at 120Hz. (No sides or surrounds are set)

    if i press 2-channel on the remote still flips to 2.0 Logic 7.

    Thanks,
    B.

    Can you try setting the PCM FX to 2 channel and see if you can change it to 2 channel? I have it set like this, and I can change it to 2 channel and also to Music logic 7.

    Glad to hear that the Velodyne is doing well. The search for the best settings is always fun isn't it (yeah right!)?

    I think you'll find that your processor is handling a digital mono signal just as it's supposed to. I havn't yet come across a processor that doesn't decode in this manner - obviously it should be an easy fix just to set it to stereo mode yourself though. :)

    OK some more experimentation. I tried with and without the default DVD PCM effect set to 2-channel.

    Either way, the processor will flick to 2.0 2-channel/2.0 Logic 7 when I press the 2 CH button on the remote repeatedly! I have to press it a few times to get it to 'stick' on 2.0 2-channel in which case only the 2 fronts are used now. Which is good. So summary of findings with this disc... :dd: Mono:AC-3:

    party, dts, tv matrix - no audio

    2.0 pro logic, 2.0 logic 7, thx 2.0, - centre only

    2.0 2-channel - fronts only

    2.0 music lgc - ~25%fronts and 75% centre

    Thanks for the input.

    Regards,
    B.
