Looks very promising. Is their a possibility to run a second board in slave configuration (for the volume control)?

This way I could control my 3-way active system, and make use of the multi-sub approach or experiment with multi-channel...

To store settings (i.e. presets) in the board's memory you use the control application.

To recall any stored preset, you use the remote controller or the menu.

Hope this makes sense!
Perfectly clear

That's possible: expansion ports have not only I2S but also I2C, SPI and GPIO.

I'm not sure however it's going to be necessary, ever. As such the board has 10 output channels. It can be easily expanded with 6 more outputs, which brings the count to 16 Unless you need very CPU-intensive processing routines, the DSP should be powerful enough for 16 channels.

Will you ever want more than 16 output channels?

chaparK, will this work ;

can I use your DSP Xover - use 6 digital outputs ( I2S) - connect it to 8 channel DAC (as Buffalo DAC BIII, use only 6 of 8 ) - and then connect on BIII something like 3 x Pass D1 (as on other diyaudio tread) ?

will this be straight forward ?

(I presume that BIII would be beter sounding then on board DAC ? )

yes

not sure if that phrase is appropriate =) the dac will be larger than most poweramps.

its similar, but less convoluted than what i'm planning but i'm using ackodacs. it will work, but your question

I dont even know if chaparK has heard his own dac section properly yet and certainly hasnt heard what you propose, so he cant possibly give you a meaningful answer.

we can presume it will be better sounding if implemented well yes, but even if he had heard it it would be a matter of personal taste, just as my preference for ESS is

I'm really looking forward to more info and pricing on this DSP. It sounds perfect for my multiple sub configuration to replace my DCX.

Thanks qusp

Jea, I have read wholl tread, and I figure that chaparK can't answer about sound and DAC,and compare it with BIII...
As I understand, he will make this project on budget,affordable to most people, and leave place for those who will like to upgrade it...if thay feel the nead for it

That's how I see it...

I will not polute this tread any more ... will folow and ask some more questions once the project will be done

Sorry for bad english,have no spell check on mobile

16 is indeed plenty. But the CS3318 can only control the volume of 8. So I would need to run another CS3318 in "slave", following the main chip.

Hi Yoke,

Connection-wise that seems OK. Regarding how it's going to sound, I can't tell you more than what qusp already wrote.

Yes indeed, we'll need to think of how to expand volume control over 16 channels.

Very cool proyect!
Which would be an approximate price of the kit (or boards)?

ChaparK, what is your website where I can see other projects from you?

waiting until October for the first production!
