Looking for feedback: Audio delay/switcher

[Gordon, Convergent-AV]

I have been approached by a manufacturer who has developed a great little box of tricks. Basically it's a digital in/out delay/switcher that will also re-clock and de-jitter the signal in the process. Each input can have it's own assignable delay time up to 2.5-3 seconds in millisecond steps. This is handy as DVD and Sky etc often require quite different delays.



I want to know whether any/many of you would purchase such a device?



Here are the specs:

(4) coax SPDIF inputs

(3) toslink SPDIF inputs

(2) SPDIF outputs (coax/toslink)



- IR receiver and remote

- LCD display to show input selected and how many ms in delay for that input

- channel select and up/dwn buttons on front panel

- RS232 jack on back for Crestron type control



Functions:



- up to 24/192 rates

- ACS/DTS, PCM

- delay up to 3 seconds with AC3 / around 2.5 seconds for DTS

- adjustable in milliseconds

- reclocks signal and dejitters

- dejitters incoming stream to below 200ps on output



Hoping for £400 or less retail

If I had a need for such a device, £400 would be less than I would expect to pay, especially for all those features.



FIFO buffering alone would probably be worth the money, in sound quality terms if your Processor is susceptible to input jitter, ie 75% of them. :thumbup:



Is the 200ps figure the maximum (good) and average (not so good) or a fixed value (really not good)?

[RobScreene]

£400 feels expensive for a buffer box to me.



At £300 it might be a no-brainer and sell 4x as many.



At £400 I'd probably trial it on a sale or return/home trial arrangement and if I heard sonic benefits (as I and most enthusiasts are likely to find!) then the £400 might be acceptable.



To me, right now, £400 is a Servo 15 subwoofer upgrade or pretty much half a D-VHS Dtheater HDTV player! £300 isn't either of those.



I don't currently use a plasma, and finally got the H3d setup to lipsync doesn't appear to be an issue, although I've read from Jenz' comments that -40ms would help even the fastest progressive scan conversion.



For me the potential benefits from reading the proposal are;

+ improves pcm audio quality

+ improves dolby digital/dts audio quality

+ enables absolute lipsync sync with any video scaler.

+ improves dolby digital/dts audio quality for a Dtheater player, plus using second input to avoid adding lipsync delay, as it's not required because 1080i doesn't need scaling to a CRT.



regards,

Rob.

1080i doesn't need scaling to a CRT......well we'll have to see about that one ;)~;-)~:wink:



No price is set. I know what estimated foreign retail is (yes it's not a UK manufacturer) and I want to make it as affordable as possible. I am endeavouring to get a proto for The Event.



More feedback please!

At 400£ I'll consider it, but I'll need to be convinced before I buy.

But I do need one as my Denon AVC A11SR does'nt have master audio delay. And my Denon DVD3800 / Panasonic PT AE100 combo have some lipsync issues.

How does it look? Is it full width, 43.5 cm?

There's always someone to throw a spanner in the works isn't there!

[Gordon, Convergent-AV]

Have yet to see a finshed unit so can't comment on case size or look.



Most amps have single delay for all inputs. This can still lead to lip sync issues on some. The AV32R/192R is the only thing I can think of that has ability to remember audio delay based on each input.

Denon's with Audio Delay have that per input ability as well. :thumbup:

So does Theta Casablanca 2. :thumbup:



There's definitely a market for a product like this, Gordon. Although I don't need one, I seem to recall some discussions going on at the TAW forum recently about TAW offering a standalone product very similar to this. The de-jittering is of course an added bonus which would help quite a few people I would think. :thumbup:

[Gordon, Convergent-AV]

Not a TAW product :lol:

[Slartibartfast]

Not a TAW product :lol:




I wasn't seriously suggesting it was! Now that would be an amusing irony! :lol:

[Gordon, Convergent-AV]

Mudge: 200pico second MAX. They expect lower in reality



Gordon 8)~8-)~:cool:

[Madge]

FWIW I've got the plans, the facilities and ability to build a one input one output FIFO buffer with delay. To build and make a profit on it, I'd have to sell it for at least £200.

Gordon's little box of tricks is way ahead in VFM terms from my point of view. :thumbup:

Gordon,



Any news on the Immersive audio delay product?

Gordon, I use a Monarchy Audio Dip. The best bloody upgrade my audio system ever got. It has improved the sound quality by improving just about everything. My bass is deeper than ever, I hear more than I did before.



I spent £500 on this at the time. Worth every penny.



Now if I could only get one for 96KHz by the same manufacturer!!

They are no longer I am afraid - a real shame as they made the best LD/CD transport in the world.



Regards - Ice.

[Nic Rhodes]

Monarchy do an upsampler already :)~:-)~:smile: To work with your DIP but this box promises to be a little different with the audio delay looking the most useful bit and then interesting stuff like de jitter and upsampling (if it is of any use) :)~:-)~:smile:

Cool. I wanted to find out if I could get a 96KHz version of the Dip and use it on vide.



I like to know more about the upsampler you speak of. What advantage does it have.



I have a monarchy Dac also (46KHz). I may have to part with these one day :(
