[edit] How to

More to come later... This is an example using a Creative Audigy1 5.1 Card.

1) Uninstall creative drivers and download and Install KXdrivers version 3538 or later available at www.driverheaven.net, not the kxproject website (those are outdated)

2) Download and install the "ProFX" and "UFX" effects plugin packs also available at www.driverheaven.net. These will have the crossover, timebalance plugins and some other more advanced EQ plugins if you don't want to use EQ's inside Winamp.

3) Open up KXproject

4) Click on 4xDSP. Everything you do will be in the 4xDSP screen.

Then you have a screen that looks like this:

You only need a few plugins to make it work.

FXBUS
PROLOG
XROUTING
EPILOG

All I did was delete or “Unload” the plugins I didn’t need by right clicking at the top of them and selected "Unload".

5) Now we need to add the fun stuff. The plugins to do crossover, and time delay, and EQ(optional). To add a plugin, right click anywhere in the screen. Then select “add effect/plugin.”

For the crossover you can select 2nd order for 12dB/octave or 4th order for 24 dB/octave. Crossover-2 and Crossover-4 are 12 and 24dB/octave crossover available from the ProFX package and will do the same thing.

6) If you want a 2 way crossover, you only need to add on instance of it. If you want a 3-way, add two instances. I will show a basic setup of High pass at and a low pass to sub.

7) I added two 2nd order crossovers and now we need to connect them to the inputs and the outputs.

8) Go to the Xrouting and hover the mouse over one of the square dots to see what that connects to. Then connect the following:

Stereo_l to in1
Stereo_r to in2

Connect this to both crossovers as shown here by clicking and dragging a connection over:

9) Now all we need to do is connect the output of the crossover to the output of the card. To do connect the following in this order it will be easier. If you connect from the crossover to epilog, it will auto connect everything for you and we don’t want that. Connect from right to left instead:

Epilog(Analog Front Left) to 2nd order crossover(h1)
Epilog(analog Front Right) to 2nd order crossover(h2)
Epilog(Analog Rear Left) to 2nd order crossover #2(h1)
Epilog(Analog Rear Left) to 2nd order crossover #2(h2)
Epilog(Sub) to 2nd order crossover (l1)
Epilog(Center) to 2nd order crossover (l2)

10) Now click in the 2nd order crossover box and now you can adjust the crossover frequency. Like this

That is how you setup a basic high pass filter on your speakers and a lowpass filter on your subwoofer/center output.

12) You can adjust the levels by clicking on the epilog box. I recommend that you play with the adjustments to make sure which jacks are routed to what and what crossover controls each output.

13) You can save your settings by clicking on the floppy icon on the right.

14) Now if you want to do a 3 way crossover (no rear speakers), you can reconnect some things. To disconnect your “wiring” right click on the connectors you want to disconnect.

15) Take the #2 2nd order crossover and connect and the in1 to the h1 of the first 2nd order crossover, and the in2 to the h2 of the first 2nd order. You might have to disconnect a wire after doing the first in1 to do the second in2.

16) Now we want to connect to the outputs. Connect the following:

Epilog (Analog Center) – First 2nd order(l1)=Subwoofer
Epilog (Analog Sub) – First 2nd Order(l2)=Subwoofer
Epilog (Analog Front Right) – Second 2nd order (l1)=Midbass
Epilog (Analog Front Right) – Second 2nd order (l2)=Midbass
Epilog (Analog Rear Left) – Second 2nd order (h1)=Tweeter
Epilog (Analog Rear Right) – Second 2nd order (h2)=Tweeter

17) Now you have a 3-way crossover. The first crossover will control the LPF for the sub and the HPF for the midbass speakers. The second crossover will control the LPF part for the midbass and the HPF for the tweeter.

You could make add in another crossover if you want to control and have overlapping/underlapping frequencies.

18) the final part would be to add the time delay. First add the plugin called “mono mix” under the basic plugins. You wll need this to mix the stereo signal to mono for the subwoofer. Then add the time balance plugin. Use the plugin called “TimeBalanceV2”.

19) Just connect the proper channels and play around with it. You will have to disconnect the connectors you don’t want connected each time you make a connection since it automatically tries to decide how you should have it connected. Here is my final example.
