hi guys, can i please get advice on how to setup the rear fill on the 6x8 using rear speakers?
i don't understand what this means :(

"It's indeed a simple trick of inverting the phase. You can do that 2 ways:
- @ input: using a biquad band, just send b0 to -1 and all other coeff to 0. It will invert the phase.
- @ output (like suggested by Dave): Just invert the signal and mix them both."

a look at my project (please correct me if you see something wrong) i used rear and front low level inputs from the head unit and out goes mids, highs, tweets, rear, and a sub,
appreciate the help.

Hello,
it looks like you were suggested to mix inverted and direct signals and send this mix to the rear channels, like described here:
www.minidsp.com/forum/dirac-series-suppo...upmix-with-ddrc-88bm

In your current setup, this is not possible to implement. Mixing of different channels on C-DSP 6x8 can only be done at the Routing tab, therefore two inputs on that tab must be dedicated to inverted front left/right signals. In your configuration, 4 analog inputs are already in use by front and rear left and right, and the digital input is not connected. If you find a way to use the digital input as well or to duplicate stereo signal on both pairs of analog inputs, then rear fill can be realized.

Hope this helps.
