You need to add an FIR filter module to your design and then load the coefficients into it, preferably from a table you have generated via some other software.

cheers

Thanks David for replay
will read a little...

But I have another question
I would like to have full control per channel
in the templates from download page we have 2way,3way,4way
but the channels are in pair, so that changes we make is automatically reflected to both chanels (L / R)

what I would like to have is like separate volume for L and R channels for tweeters or any other channels (have plans to add some subwofers so I would need more different control for L and R channel)

Before I burn something, I touth to ask if someone have some experience and
does setup in the picture looks o.k.

I take 2 channels and separate them to mono L and R ( I hope )
than take L (R) and add 4 way crossover to it
and connect those 2 x 4 channel to the 8 channel output

This way I could add different controls for each channel...I hope

so does this scheme looks fine

Hi Josip

If you want the channels to match up with the labeling on the back of the unit then you need to assign them to the interleave block where the ordering is such that the top input is channel 1 and the bottom input is channel 8. Always pays to check with a scope, the built in VU meter ([Main Menu] -> [VU Meter]) or a full range speaker etc before you connect up your drivers.

Also depending on the firmware version you have installed there is a level trim adjustment for each individual channel available from the menu ie [Main Menu] -> [Setup] -> [Setup Audio] -> [Level Trim].

regards
david
