AV2 Problem

I'm working from very hazy memory but don't the V1 & 2 inputs have to be configured for centre channel use in the settings? I'll dig out the manual in the morning to confirm as I run my Denon via the V1 & 2 inputs for analogue surround too. 

Presumably you are outputting via a digital lead from the player to the AV2? You might want to check the settings on the bluray that its outputting 5.1 and not pcm

so frustrating ! I've messed around with the cables and the versatile 2 input on the av2 isn't working despite being aligned with the versatile 1 on there same input.  Messed about with the cables and its definitley that one.  Ive moved both vs1 and 2 onto another setting as well and still no joy. Can you reboot it would that do anything ? if so how ? Odd not working and new blurry player sitting redundant till i can get centre / sub and rears working !

They are not digital therefore you cannot receive 5.1 on them. you need to output from the DVD player via an optical or digital RCA lead into the back of the AV2.

It sounds like you have been running 'sudo surround; such as the neo settings, this is not 5.1

hi gary - the pioneer and the oppo that just arrived give you the option to output directly to the speakers in true or master hd bypassing the av2s decoder using cables off the rear.
Worked a treat in the uk and since the chinese naim installer messed about with it hey presto doesn't work properly !

Emailed naim hq see what they say

So using the Oppo as a processor direct to the speakers without the AV2 in the chain, can you get sound from the centre channel?

You will not get 5.1 audio from analogue inputs. I have no idea how you had it set up in the UK, but it was probably a sudo surround mode.

Although all in all I am confused by what you are saying. I am assuming you have a DVD player of some kind connected to the AV2 and the AV2 is handling the surround sound duties on all five channels?

In short the versatile sockets on the back of the AV2 are Inputs, not outputs and they are analogue so they will not deliver 5.1 and you need 5.1 in order to have a centre channel.

You have digital options on the back of the AV2, the DVD player needs to connect via one of these, this is the way to get 5.1 surround.

I think!

The oppo presumably has  amps on board therefore if its outputing direct to speaker, whats the AV2 therefore at all?

For what I can remember of the time I had DVD5/AV2, I only used the two analogue inputs 1 and 2 on the AV2 in 'combined' mode when I installed the multichannel boards for DVD-A multichannel replay on my DVD5, and I had to connect it to the AV2's 1 and 2 inputs to replay multichannel audio.

Safe for that, I only and obviously connected my DVD5, and then my Oppo DV980H, via a single digital coax to my AV2 and let it do any processing for cinema, in any cinema format from mono to 5.1 DolbyDigital.

So, unless you are using the configuration you mention for audio multichannel replay, I cannot completely understand the use of an AV2 as analogue preamp... Unless I am grossly misunderstanding something in your post.

Could you explain a little more, please?

Thanks,

Max

A quick look on Wikipedia shows me that the audio coding for BluRay seems to be the same as for the DVD, so what's the problem in connecting a BluRay player digitally to the AV2?

Again, if I am not missing something ...

gary,

on my Oppo I had to set the output to 'raw', and this made sure my AV2 automatically selects the proper format.

Something in the OP's explanation still escapes me, though..

I dont own an av2 but the inputs he refers to are analogue. My understanding is he has an oppo dvd player connected to it via that input. But he is saying something about the oppo having direct to speaker or something, it sounds for all the world like the av2 is not required in his set up.

Thats possible, but of course it wont give you centre, you have a stereo configuration of some kind, although i dont know of any hifi That uses two inputs at the same time.

in short if you want a centre channel use digital not analogue.

We have been in touch with Gerald, and he is looking to provide us directly with some images and details of the installation so that we can help him get back to where he wants to be with this.

For clarification for other forum members posting on this thread, Gerald can choose to connect his kit up in one of two ways.

1) The simple method, where the Oppo runs HDMI to his screen, but sends a downmixed version of his BluRay soundtracks to his AV2 over digital COAX, as Dolby Digital or DTS (as opposed to Dolby TRUE HD or DTS Master Audio).

2) The complex method. The Oppo has a very capable AV processing circuit, which can be used to decode all soundtacks of any discs played into a multi-channel analogue output. (it also has 2 HDMI inputs for other sources). It is possible to either connect an Oppo direct to multichannel power amps and use its volume control to replace the AV2, or to disable the volume control, and run the multi-channel analogue output through the AV2's VI inputs - effectively turning the AV2 into a multi-channel preamp.

Given that Gerald has an Oppo 103D, it is potentially beneficial for him to use both connections... the AV2 will probably sound better when decoding regular DD or DTS from his DVD collection, but the Oppo should do a better job with BluRays.

We are hoping that via some email traffic we will be able to help Gerald get everything doing what it should quite swiftly, or at least be able to fault-find so we know what item needs fixing.

Many thanks

I have a oppo 105 using it through the AV2 in the analogue route with no problems. Before this i used a Denon 3800BD in the same way and again no problems.

I am really struggling to understand the point of the AV2 in this context, its neither decoding or controling volume, just seems like a pointless filter between the oppo and the amps?

Sorry if I have caused confusion with my confusion!

Some BluRay players decode the surround sound internally into 5.1 or 7.1 line-level analogue channels. this is then input to the AV2, which then acts as a volume control for outputs to power amps. The AV2 can be adjusted for channel volume balance (but not for delay) using these outputs.

Delay is usually available within the decoding of the BluRay player. 

The advantage of using this arrangement is that the BluRay player will decode the HD surround formats, then pass this to the AV2. The AV2 can only decode standard DD/dts via its digital inputs, and has no HDMI input.

That is exactly what I do to integrate my AV with my audio, works very well.

But surely though analogue inputs into the AV2 you cannot do 5.1? or even surround sound?
