tigerwoodKhorns Posted June 23, 2017 Share Posted June 23, 2017 Will all optical inputs accept 5.1? I have a Denon AVR 5800 and it is only playing 2 channel from my TV's output (Samsung JS8500). The Denon is from 2000. Is that before 5.1 through the optical was utilized? Thanks. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted June 23, 2017 Share Posted June 23, 2017 I believe optical will support 5.1 but only a compressed signal. 1 Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted June 23, 2017 Share Posted June 23, 2017 It should do DD, DD Plus and DTS but, not Dolby True HD or DTS Master. If the avr is not showing it, check for updates. Quote Link to comment Share on other sites More sharing options...
Loudly Does It Posted June 23, 2017 Share Posted June 23, 2017 Your receiver is supposed to put out 5.1 discrete audio and 7.1 stereo signal. Optical will carry 5.1. Is it not doing it for every show? Some shows might not be transmitted in 5.1. Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted June 23, 2017 Author Share Posted June 23, 2017 I am using the TV's optical output to the receiver. Only getting two channel on the receiver. Quote Link to comment Share on other sites More sharing options...
USNRET Posted June 23, 2017 Share Posted June 23, 2017 @tigerwoodKhorns I use optical from my TV to my Mc prepro (I only use OTA). I get hit with 5.1 when the broadcast is 5.1 but most aren't. Quote Link to comment Share on other sites More sharing options...
wvu80 Posted June 23, 2017 Share Posted June 23, 2017 I have an older 5.1 Pio I use with the computer, ie Youtube. The toslink only gives me 2.0 but it is a much better sound than with my RCA cables. Quote Link to comment Share on other sites More sharing options...

dtr20 Posted June 23, 2017 Share Posted June 23, 2017 Your tv's optical may not be able to output 5.1, or you need to change a setting on the tv. Do you have a cable box? If so, go straight from there, if possible. Quote Link to comment Share on other sites More sharing options...
USNRET Posted June 23, 2017 Share Posted June 23, 2017 Got anything laying around (DVD player) that has optical out and media that has 5.1 audio so you can test the input? Only thing I see with your AVR is that optical 5 & 6 are 'special' for 2 channel recording. Page 46 of manual says DD and DTS available via optical and coaxial.

adam2434 Posted June 23, 2017 Share Posted June 23, 2017 Most TV optical outputs are only 2 channel. A few will pass 5.1 though. Check the digital audio output settings on the TV to determine if there multiple choices, for example "bitstream". Even if the TV optical is only capable of 2 channel, the benefit of using it is that the audio will be in sync with the video. If you use the digital audio output from the source (cable box, disc player, etc,) the audio will likely be ahead in time vs. the video due to the TV's video processing lag. If your AVR has an audio delay/lip sync feature, you can delay the audio to sync with the video. Quote Link to comment Share on other sites More sharing options...

I am wondering if the older equipment is programmed for 5.1 through the optical link. Pioneer VSX-D514. No HDMI and it looks like a very early implementation of 5.1. It was $330 entry level, circa 2001, 2, 3. Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted June 24, 2017 Author Share Posted June 24, 2017 OK, thanks for your help. I put the optical on my DVD player and popped in a 5.1 disc and no surround, Then I hit a button called "Dolby Surround" and like magic I have surround sound. Hooked it back on the TV and now I have 5.1. I have had a bunch of speakers sitting not used for a while because I did not have time to address this. Thanks again.

USNRET Posted June 24, 2017 Share Posted June 24, 2017 There you go. i don't think i will ever figure out my options Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted June 24, 2017 Author Share Posted June 24, 2017 OK, I need more info from the experts here. I watch youtube and we stream on Amazon. We rarely if ever watch DVDs or bluerays. I use my TV as the source and it is outputting via tosklink to the receiver. As you said, it will do Dolby Digital and DTS which are each 5.1. Looking at the buttons, there are 6.1 and 7.1 options which can be matrix and non-matrix. I think that this creates the rear surround channels from the 5.1 source. I am pretty sure this receiver is going to do all that I would want it to do. Am I missing something here? The receiver is 170 wpc x 7 and I really want to keep it. 1 Quote Link to comment Share on other sites More sharing options...
willland Posted June 24, 2017 Share Posted June 24, 2017 Your 5800 should be just fine for what you need to achieve. Bill Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted June 24, 2017 Author Share Posted June 24, 2017 Thanks. This is from the second wave of "monster receivers" at the turn of the century. I guess that they were trying to emulate the big SS receivers of the 70s. This receiver has great DACs and a huge amp. I remember you mentioning the NAD receiver that you have and you feel the same way. Quote Link to comment Share on other sites More sharing options...

Yes your Denon and the Yamaha RX-Z9 are the two main behemoth AVR's from the early mid 2000's that were "separates like" in performance and both tipped the scales at over 61lbs. 34 minutes ago, tigerwoodKhorns said: I remember you mentioning the NAD receiver that you have and you feel the same way.

willland Posted June 24, 2017 Share Posted June 24, 2017 I almost forgot the other monster AVR from back then. The Integra DTR-10.5 which bests them all at 70.8lbs. Bill Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted June 24, 2017 Author Share Posted June 24, 2017 There is a Marantz sr18 for sale locally. Looks to be another monster receiver. Quote Link to comment Share on other sites More sharing options...
