What's ARC?


Audio return channel. I use it with my roku, HDMI from the roku to my tv, then HDMI from the TV to my receiver so that the audio goes to the receiver. But both the TV and receiver need to support it.

Ok, it's also got a digital (coax) or an optitcal (s/pdif) hookup. Which is better?


Digital Coax, and that's the only one it has, no optical on the HR34.

I run an optical from my Sammy back to my AVR (Denon) with fine results. The Denon will support 3D, but I choose to do it this way mostly because there are times I don't want or need big sound, and can keep the AVR off.


my Denon (2809ci) is a great receiver but too old to support 3D.

Do you think it's as good as if it were HDMI?

That's one vote for optical. Thanks for the info.

Just one? That's terrible. My receiver doesn't support 3D so I have to run 3D directly to the TV but I need to run an HDMI to the receiver for my sound system. Looks like I can't do that with the HR34.

Having just one HDMI output sucks!


Actually it makes no sense to have more than one hdmi. And the amount of issues and additional horsepower that would take would be unreasonable. That's why they have coax audio out.

The specs on DTV say there is an optical, but it's stereo only.

BTW, do any HDMI cables come with this DVR and if so, are the the latest 3D compatible cables?

No cables come with any units now, AFAIK. I doubt there are cables now being manufactured that don't support 3D.

There is no optical out on the HR34. Not sure where your seeing that but its wrong. And you will never see a unit from DIRECTV these days that's optical out and only stereo.

TOSLINK is a thirty year old technology. In most cases the audio quality should be nearly identical. They're both digital.

Additionally, if you need to a length longer than 15' TOSLINK is not recommended. The spec limit is 10m but the usual practical limit is 5-6m.

I know a few audiophiles who swear by TOSLINK for short runs.

I guess, depending on how you want to use it you could easily argue both sides.

Personally, I prefer digital coax. The cables are cheaper. :D

Since it costs 1.66¢ to produce a penny, my 2¢ worth is really 3.32¢ worth.  That 3.32¢ is my own and not the 3.32¢ of DIRECTV, Dish, or anyone else for that matter.

If you're referring to S/PDIF, it's a spec that can be either TOSLINK, or coax (as well as STP and BNC). The only listed digital audio I see listed is coax.

You can see in the First Looks (Link) the HR34 does not have an optical connection. I have a TOSLINK/HDMI switch and have to use a coax to optical adapter from my HR34.

Really? I don't remember Toslink outputs on any of my AV equipment 20-30 years ago. I'm not doubting you, but I didn't think it was that old.

Toshiba released TOSLINK in 1983 to connect it's CD players to it's receivers. It used the S/PDIF optical connector. S/PDIF was a new spec from Sony & Philips that was introduced in 1980.

IIRC, TOSLINK is short for Toshiba Link but don't quote me on that. As S/PDIF became the industry wide standard through the 80's TOSLINK became more of generic term to the fiber optic audio cable.

This also makes all the single cable digital audio 30 years old.

Um, I just read that page, and under specs it says its coax digital out. No mention of Optical anywhere. And no where does it say its stereo only. It does say you can get stereo out of l/r analogue outs or the coax digital out though. Very different things than the way you are reading it.

Yeah, but the truth is, that optical outs require more conversion than coax digital outs.... Unless you have one heck of a setup, you won't hear the difference. NAND I mean 10k and up audio system. Or your using the wolds worst digital coaxial audio cable...

I helped design the high end TAW DVD player over 10 years ago and the digital coax is definitely the better connection, or at least capable of being that anyway. The 2 main things we did to make it "high end" were adding an SDI Video output for connection to our TAW Rock+ Award Winning video scaler/ processor and the addition of a high speed, high bandwidth digital coax audio out (this is before HDMI, etc.). As an example today I think you can look at the Denon HDLink. I remember asking our owner/engineer the difference and he explained that the coax is more "pure" and the optical is derived from the coax signal, in other words the electrical coax signal is converted into light pulses for the optical cable and the only way he could get that performance, speed, bandwidth, etc. was to use coax, as TOSLINK optical wasn't able to handle it.

Disagree with the fact that it doesn't have Optical? They can disagree all they want but as soon as they look at the back of one they'll see they are wrong.

As far as quality of signal they are nearly identical. What makes coax better is 1. it's better over longer runs and 2. it's not as fragile as optical.

Did the choice to use coax over TOSLINK have anything to do with jitter?

Here's the quote:

Audio Outputs
1 Digital (coaxial),
1 Stereo (L/R, RCA), 1 S/PDIF
(COAX)


You guys have the machine and I believe you when you say no optical, but the DTV specs sure confuse me. I thought S/PDIF was optical but they qualify it with (COAX) so it's not optical?

And yes, I read that the first time to be Stereo for everything on that line, but see now that's not what they intended.

As I stated earlier, (link) S/PDIF is a spec that involves multiple connectors including TOSLINK and coax. ;)

Yeah, that's what it says alright but nowhere does it say optical. Read carefully, it says coax twice.
