  • Hdmi lowered output

    I just hooked up a Blue ray player running Hdmi from the player to my receiver to the tv. Got everything to work and used the primary pass-thru to get dolby digital. So I whipped out the SPL to check my settings. None of the settings really changed except for my sub setting. I'm running a MFW in a 15x15 open room, before I had the sub set at -6 on the avr and that was +3db's hot. Now with Hdmi hooked up I have it set at -1 at 75db's, I would have to go in the positive to get +3db's hot. I have no idea why it would change the sub output so much. Do I still need to run a digital cable or optical with Hdmi?

    I recall seeing a thread on AVS about some receivers not properly decoding the LFE channel across all HDMI source types.. You might try searching there for some more information as well. If you are doing lossless audio over HDMI there is no need for additional digital audio cables between player and AVR. What is your AVR? Not that I would be able to help you any better though (but someone else may).

    sorry it's short-- just popping in while wating for something to compile at work..

    cheers,

      Thanks Dane. I did a search and turns out my receiver H/K 247 is known for the LFE low ouput. I managed to get it to sound decent using the Hdmi cables.

        if it is truly just a lower output signal, you should be able to compensate with a higher gain on your subwoofer. Though other non-HDMI sources will also be affected. Unsure if your HK AVR supports different sub outputs for HDMI/DIGITAL/ANALOG inputs. (most likely not)

        good luck-- glad you at least found the root cause to your problem.. knowing is half (or more?) the battle...

          I went from -6 on the sub setting to +2 to get to the same output as my speakers. It's a fix for now until I decide it's time for a new receiver.
