Just got some LS50s as surrounds to round out my 4.2 system. I'm currently using an old 1080p Denon (AVR 1912) hooked up via optical.
My question is, what is the best surround mode to use? My options seem to be: stereo, Dolby pl2 cinema, Dolby pro logic, dts neo: 6 cinema, multi ch stereo, and mono movie. Does each movie get mastered using a different surround sound profile, making this process a guessing game, or is one generally the best to set and forget (and least artificial/overly processed)? I'm guessing video games are a similar story. I naively assumed that I'd pop in a blu-ray and the appropriate track would be selected for me.
Second, being connected via optical, what am I missing out on sound wise? Is it worth it to upgrade if the amp section is fine?
Third, I find that I need to crank my surrounds up by like 10 DB in the receiver to get them to feel like they are doing anything. Otherwise, they are too low compared to the fronts and I can barely hear anything.
Finally, am I missing anything by not having a center channel? I don't feel the need for one, but you never see a 4.2 system, and I'm curious if just buying a center would simplify my options.
I am totally mystified by receivers and surround sound in general, so any help is greatly appreciated. I'll pass on any knowledge I obtain.
This is the right place!
With movies for your 1912 you really have 2 choices: Dolby Digital and DTS which are 2 different sound formats that most media come encoded with which brings me to:
Decoding. Your AVR receiver will decode what the media was recorded in...your AVR does DTS 96/24, DTS-ES Discrete 6.1, DTS-ES Matrix 6.1, DTS-HD High Resolution, DTS-HD Master Audio, Dolby Digital EX, Dolby Digital Plus, Dolby TrueHD...
Movies do not come encoded with mono movie, 5 and/or 7 channel stereo or Neo cinema or music modes. These are DSP profiles used usually for 2 channel sources to envelop you with more sound than the left and right speaker.
You can use HDMI Arc instead of optical. Optical has limitations and can do up to 5.1 audio. Should you want more than That? HDMI is your huckleberry.
Never ass u me. DVD/Bluray discs have settings to choose which format you want to hear. I've found Denon's older DSP to be worthless.
You should not have to crank your surrounds to 10db! What do you have your other speakers set to? I have my rear surrounds at + 3.5db and they are calibrated via my AVR.
I remember those older Denon's not having the best decoders or some limitation that greatly reduced rear surround output.
You are missing better dialogue, better imaging by cramming the center output into your left and right speakers. I feel the center is the heart of any HT. Timbre matching the front 3 channels is also important.
