Select the multi-channel analog inputs (aka "external inputs") on your AVR for playback.Boost the sensitivity of the subwoofer (LFE) channel of the multi-channel analog input in your receiver or pre/pro.Do the speaker configuration (levels, delay and bass management) in the player.Run analog audio cables from the player to your receiver (6 or 8 RCA cables).Get yourself a player that decodes Dolby TrueHD and DTS-HD Master Audio, and has multi-channel analog audio outputs (5.1 or 7.1).This can still sound very good (in fact, Blu-ray supports higher bandwidth versions of regular Dolby Digital and DTS than DVD ever did) but it won't take full advantage of the lossless soundtracks which are bit perfect copies of the original studio masters.īut don't despair! If you don't have HDMI audio support on your A/V receiver or preamp/processor, but you do have a 5.1-channel or 7.1-channel analog audio input on said device, and you still want to take advantage of the latest high bandwidth and lossless audio formats available on Blu-ray, here's what you need to do: If you try to do it, you'll get a "lossy" Dolby Digital or DTS soundtrack instead. Dolby TrueHD, Dolby Digital Plus, DTS-HD High Resolution, DTS-HD Master Audio - even multi-channel PCM - cannot be sent over traditional optical or coax S/PDIF digital audio connections - these connections simple won't fly when it comes to meeting the necessary bandwidth and copy protection requirements. HDMI (High Definition Multimedia Interface) is currently the only digital interface that can properly transmit the newest surround sound formats. But, if you have an older receiver that lacks HDMI audio support (but does have a multi-channel 5.1 or 7.1 analog input), then you have your work cut out for you in order to get the best possible sound quality from your fancy new Blu-ray player. Sure, you'll have to figure out what "Secondary Audio" is and you may have to learn the difference between "bitstream" and "PCM" but you won't have to change any of those hard-won settings on your A/V receiver. If you have a newer receiver that processes audio over HDMI, then the set up for the lossless audio formats (Dolby TrueHD and DTS-HD Master Audio) is mostly plug-and-play. Up to 7.1 channels of pure lossless surround sound at 96 KHz and 24 bit precision? It absolutely boggles the mind! And it's the audio set-up options that are easily the hardest part of going Blu. Teach Your Old Home Theater Receiver New Lossless Surround Sound TricksĪlthough Blu-ray Disc's 1080p full high definition picture gets all the attention, the surround sound audio formats available in Blu-ray are equally as impressive as the video.
