DSP speaker crossover

(1/5) > >>

CraigNZ:
Is it possible to select an audio channel (for example left channel) and define a 2 way or 3 way crossover for output to 2 or 3 amplifiers.  I would want to set the crossover frequency, Low Pass Filter or High Pass Filter or both, and the type of rolloff, eg LR24.  Would also like to set the phase and delay time.

I have a 5.1 system but the LEFT and RIGHT front speakers are bi-amped.  Currently what I do is take the audio channels and pass them through an external crossover box (Behringer Super-X Pro CX2310) but it has a lot of limitations that a DSP crossover would do much better at.

So instead of assigning a single output audio channel to a audio stream channel, we would now assign a DSP crossover to the audio stream channel and then assign the two or three outputs from the crossover to multiple output channels.

Matt:
MC is quite good for this type of task.  It can runs any number of channels and any number of filters.  Everything is done with 64-bit precision.

To start, you might explore 'Parametric Equalizer' in DSP Studio.

I use MC for a 3-way active crossover and it's flawless once you figure it out. Like Matt said, dig into the PEQ. "Mix Channels" will be your friend. Let us know if you need help with that. I have a post somewhere that I think JimH added to the Wiki with a how to for mixing channels for an active crossover but I can't find it.

CraigNZ:
Thanks guys, good to know it can be done, now to figure it out.  The mixing is what I could not see so will look at that closer.  Maybe what we need is a tutorial on setting up a 5.1 system with bi amp'd mains.  If this does not exist I'll make notes and add one.  Using DSP crossovers is amazing what it does for the sound.

CraigNZ:
Where do assign a source channel to a windows output channel?  For example, I have an Echo Audiofire 12 DAC which appears as 6 soundcards in windows.  If the LEFT source channel is bi-amp'd, how do I assign the high pass filter output (tweeter) to the second channel on the 3rd soundcard and the low pass filter output (woofer) to the first channel?  This assumes the third soundcard outputs will be cabled to the two amplifiers.
