Um. It's a solution to the volume sync problem, that's all. I've given my reasons why I don't think there's an issue. But, try it, measure it, or not, doesn't matter

Sorry John, I do tend to jabber on sometimes.

OK.. i am not so skill as you to decide what is better or not.
I think , i will try to cascade the both and pray for a better world
It is a HT system and i guess i do not need such high perf as you.

Maybe i will be out of scope with my following question but i have read some application note to learn a" little" (big ?) more on this product and i was surprised to learn that the Bass management (BM) must be done only after all the channels have been EQ.

It is strange for me because if , for example, i set the EQ for Front Left speaker "perfectly" and i remove a part of this response (under 70Hz for example) to send it to the Sub Out channel, then all my task for this part of frequency is lost and not re use by the Sub out channel. (i mean, as the sound is now coming from the Sub, its position is different from the Front Left speaker and adjustement for this part is different.)

As the BM is done at the end (after the Equalizing operation of all the channel including the LFE channel), it seems that a new setting of the parametric EQ of the Sub Out is necessary because only the LFE channel has been EQ (and the parts that have been added coming from the others channels are not anymore EQ) ?

Do you understand my problem of understanding ?
If no, i will try to explain with others words.

edit : i try to give an answer to my question ....
It is not neccesary since the frequency parts added from others channel by the BM will use the EQ already done for with LFE signal (?)
But in this case, why the BM has to be done after the EQ of all the channels ?
My feeling was to do the opposite that is specified.

One thing to keep in mind is that I may actually have no idea what I am doing over here.

As to your bass management question: I don't use that feature on the nanoAVRs, so I'm afraid I can't be much help with that one.

Dear All

The Full Gonzo system community is growing it seems..
- IP commands: Sure, we'd be happy to send these if you guys need them. We don't want to publicize them though as we'd prefer a tech support ticket where we can outline the limitation of our support (i.e. we don't want to turn ourselves into "socket programming" teachers..
- nanoAVR App: Maybe missed by some of you but the greatest thingy we worked on for few weeks is the fact that the Android/iphone app will support "LINKING" of multiple units. i.e. volume control/preset control won't be an issue anymore.

Good luck for your project.

Hello.
Thank you very much for this information.
I am not ready to implement immediatly but i take your proposal to contact the support when i will be at this step.

Great App to be available soon !

Hello.
i come back to you with a question.
The assupmtion is still to use 2 NanoAVR HDA but in serial now.

As defined previously, the first NanoAVR will manage the BM and surrounds, the second will manage the bi-amp LCR.
For the BM, in addition to the normal cutoff of the 7 channels , i would like to manage a Low Pass filter for the LFE in and put all the frequency above the lowpass filter into the Center channel which is managed by the second NanoAVR.

Is it possible ?
Here below how i feel it is possible :

In the first NanoAVR HDA, i will put in the matrix (defined page 3/8 of the application note done for the BM management) the value 0 dB (or probably +10dB) at the cell coresponding to LFRin/CTR out.
Then it is only necessary to apply a High pass filter to the center channel in the second NanoAVR to have a good result.

Of course, i must also set a low pass filter on the LFE channel into the BM setting to avoid to dupplicate the signal coming from the LFE channel which will be now managed by the Center channel.

Thank you for your confirmation.
