DSP speaker crossover

Jamesey:
On this topic, can we also get a proper display of what the Parametric EQ does to the frequency response? I know we can play pink noise and observe the output, but that line bobs up and down. A line like what computer parametric eq's show would be much more useful.

In my setup, (2-way stereo) J-river does not label the output chanels the same as windows. So it may take some trial and error to figure out... For example my dac has channel ouputs 1,2,3,4.
from memory my
chnl 1 = left
chnl 2 = right
chnl 3 = surround Left
chnl 4 = surround Right

In PEQ: I first copy the Left & Right channels to the surround channels, then apply my x-overs ...
Hope this helps ...

If no one else does in the meantime, when I get home I'll post a tutorial that shows how to mix channels for an active crossover (if I don't forget!). I also use an Audiofire 12 so I'll be able to tell you the channel assignments.

CraigNZ:
The AF12 can be configured in one of two modes: Stereo, Surround.  In Stereo configuration the 12 channels appear in windows as 6 stereo sound cards.  In Surround configuration the 12 channels are divided into two soundcards, one sound card has 8 channels and the other sound card has 4 channels.

One possible configuration is to use the 4 channel sound card for the bi-amp'd LEFT and RIGHT main speakers and then use the other sound card for the surround channels.

If doing a 3 way system then then 8 channel sound card would be used since the LEFT and RIGHT speakers wold require 6 audio channels.

mojave:
When using ASIO output, the mode configuration and Windows settings don't matter. You should just be able to choose 12 channels in JRiver use it as a 12 channel soundcard. Natehansen66 will show you how.
