AV unity gain question

Yes it will solve your problem. I have to say however that I don't find it a real problem despite having three volume controls (AV processor, Naim amp for LR and other Naim amp for rear). I don't have unity gain mod.

The unity gain on my Nait5 works fine with my Yamaha surround amp. The rear/centre levels just needed matching via the surround amp's set-up procedure.

Thanks. Any idea of the upgrade cost for a 52 and does it need to be sent back to the factory?

Is it not just a case of setting the 52 volume control at the same position each time you use AV e.g. 12 O'clock for easy reference or have I missed something.

That is basically what I do but the unity gain mod means that all volume adjustments are controlled consitently by the AV processor. The pre-amp with unity gain does not amplify the output from the AV processor whatever you do with the volume control on the pre-amp.

Actually there is something to be said for having independent volume control of the Naim pre-amp.
I find the channel balance between rear & front channels as output by the DSP is often different for Music and movies. Particularly on music it is nice to have the option to boost the volume in the front channels to compenstae for too much volume in the rear channels & saves having to adjust it at the A/V amp which is typically a lot more fussy.

That`s a reason why the AV2 has both a music and a movie modes in Prologic and Neo6.

I had the unity gain mod carried out on my 52. it cost a tad under £120 (18 months ago) and yes it has to be done at the factory.

I'm still undecided about my approach to adding AV. The AV2/175 + new naim DVD is rather pricey - so am considering the denon/pioneer route.

Thanks Peter. Out of interest which models of the Denon/Pioneer route?

The Denon on my list includes the 2900 DVD player and Denon 2803 receiver.

Having moaned a bit about the high cost of AV naim stuff I last nite measured up available space. The denon/pioneer stuff is very 'chunky'and not so easy to fit in as the slim line naim AV2/NAP175 and presumeably the new DVD player and of course wont sound as good.

You get what you pay for so - naim is back in the frame as far as AV is concerned(no pun intended).

Cheers
Peter

Thanks Peter.

Naim would be great but I can't justify the expenditure at present as I am trying to be grown up. Yes they are horribly chunky and wont fit on a Fraim.

I have noticed there is a delay when using progressive scan so that the sound and vision do not match - i find this really annying and shatters the illusion. I see that the Denon 3803 has a function to compensate for this, I wonder if AV2 does and if this is a rarity as I have never heard it mentioned.

For info

I have just accquired a Denon 2900 mainly for DVD movies but also for it's DVD-A/SACD capabilities.
It ain't half bad. The movie side of it looks good to me through progressive component out (both for NTSC & PAL).
On DVD-A it has pretty good DSP which does a nice job of developing a total sound field rather than the localised "this is coming from this speaker" sort of sound that is often heard from relatively low cost DSP.
On SACD it also does a good DSP job and produces a slightly "warmer" sound than seems typical of SACD I have heard in the past from SONY, but neverthless pretty good dynamics.
IMO it is pretty good bearing in mind the realtively low price (600 ish GBPounds w. discount) and the fact that it has to be a jack of all trades.

BTW Don't even consider it as a CD Player, there it sucks!!

I ran my A/V using a Denon 3802 in combo with a 112/hiCap/150 using Unity gain,at one time. The channel amps are certainly quite powerfull and seemed to integrate quite well with the naim sound coming out of the front pair. The 6.1 channel DSP was pretty good and "shock horror" a mode called "7 Channel stereo" was fun to listen to. The only issue I had with it was a "hum loop" which was inherent in the way you had to connect it to the unity gain output on the 112. I could not get rid of it no matter how hard I tried.
It was only present when unity gain was switched on.
For other reasons I traded the Denon in for a SONY A/V and had no problems at all with hum loops from then on even though the connections were unchanged, so I have to assume it was due to the Earthing approach used by Denon, (whatever that is/was).

hope this is usefull.

Interestingly I had an opportunity when upgrading to drive the front channels via my new 250 and the rear channels via the outgoing 150 with no center channel and compare the sound with the sound created when my SONY A/V was driving the rear channels. To be honest could not hear enough difference to justify investing in Naim amping for all channels.

However I agree you get what you pay for. When the Naim DVD arrives I may consider the AV2 as the DSP.

David,
The curent AV2 does not compensate for the delay. But Naim has told it will be added when the VS1 will be released.
Will we have it with the DVD5?

Thanks for all the helpful responses. Forgive my ignorance but what is digital switching? I will be going for the DVD player when it comes out - any idea of the cost? Am I correct it will also play SACD?

Salut Manu,

J'ai répondu dans le topic privé.
Merci

Any ideas whether or not Naim will be able to address region coding on their DVD player? And how much do we think it will cost?

From what I heard the plan will be that a card can be added for EITHER DVD-A or SACD but NOT both. It will be the buyer's choice.On digital switching I would assume what your asking about would be switcing sources whilst they are a single digital bitstream rather than as discreet analog channels. The other thing that is happening is the introduction of digital interfaces for both audio and video so that signals can finally be passed between digital components without having to go from D/A at source then back thru' A/D at destination. Example connecting a DVD to a projector or a plasma display which are digital in operation OR passing a DVD-A PPCM digital signal direct to an A/V DSP processor rather than decoding into 6 discreet channels before reaching the A/V amp and having to by-pass option to do DSP right at the amps.

For sure they will be able to configure region coding else they would loose a big chunk of business around the world. If things go the way they go for other makes of DVD players made in the UK it will be up to your friendly dealer. Most likely when requested they will make it "multiregion". In this day and age region coding is another one of those farces like copy protection.

On price the player is rumored to be about 2000 GB Pounds and I would expect changing it to "multiregion" should be free, since it is a 5 minute operation on any DVD player I have heard of.

As always these commenst are open to correction by the experts.

Geoff. Thanks for the reply.If they price it the right side of £2000 then I think they will get a lot of takers. Perhaps when they launch it we will also get an AV corner...
