n-vi ( in stock )
Posted by: john R1 on 01 May 2006
browsing on the internet, see a naim dealer stating n-vi in stock, i presume these must be old stock, i would have thought with all the problems i have read about on the forums they would have been re-called until all the problems had been sorted out ?

John,
Synching audio and video has been a problem with the media for a very long time, be it broadcast media or AV media (DVD/VHS). Most decent surround processors have a lip-synch feature to help the problem exhibited by the original medium i.e. a (typically digital) broadcast or a DVD. This is not a fault of an n-Vi or, indeed, your AVR3805 which also has a lip-sync feature! It's only very basic processors that do not have a feature of this sort, which is a bad thing. Incidentally, the n-Vi is one of the few that can handle really gross errors of 250ms.
I think the waiting has really got to you John.

I have this very morning passed a digital (optical and co-axial) and analogue signal from a DVD5 to an n-vi (analogue1, digital1 and 2).
with a film playing from the DVD5 (both 5.1 and 2.0) through a sim2 projector and the sound going via the n-vi digital/analogue inputs, there is NO delay.
I have also run the 2.0 signal as PLII, neo6 etc....still NO delay.

The change of sample rate (available from service menu) is only available on 75 or later PIC code.

Thanks for that. That seems to be a conclusive test although it would be neat if you could try with Sky comparing A1 and D1 from the same Sky box.
I've spent a while on the phone to Sky this morning who are certain that this level of delay is not a problem with their service. I've also just plugged the analogue from Sky into A1 and there are no delays on that (but no DSP either!).
So this leaves me a couple of choices:
1) Wait for my new n-vi to arrive and hope that the issue disappears. The fact that my "first gen" n-vi is a sick puppy in many ways may be clouding the issue.
2) If it persists with the new box in place, maybe look to change my Sky+ to a newer box. Mine is at least three years old. "First gen" again. A friends Sky+, a bit newer, has no such problem with it's dig opt output.

duncan,
On the n-Vi:-
Can you tell me what values are opposite A0, A1, A2, A3, A4 with your sky box attached and running as normal via n-Vi.

A1 100
A2 000
A3 002

Duncan,
To set the PCM freq:
Press and hold angle.The service menu will appear
Select PCM FREQ - it is on the 3rd line down.
Then select D1 (optical)
Then select 48kHz.
PS my sky box would be more than 1/4 second!
Its been ok for a few months now.
What s/ware are you running?
I've got V163 and V75 - working fine for me!
(press and hold PROG to find your version.

As I said, he wont be able to do this on pre 75 firmware

Problems with lypsync
I have had the same problem as the post above but have noticed on Sky+, that when watching a pre-recoded program there are no problems with lyp-sync, I assume that is because the data is coming from the hard drive and not from a satellite.
I'll try the set-up as suggested 110db!
