Are the high pass / low pass filters available via the Configurator menu IIR or FIR filters?
The SHARC DSP chips should be FIR-capable, but I haven't been able to find any information on the type of filter used.

I think FIR, someone asked previously, but I cannot find the post right now, and I'm not 100% sure I remember correctly.

The post was about crossing over to subs I think, and was taking about phase shifts, not using IIR or FIR terms. Hopefully someone else can remember. I think someone had measured, not relied on asking support.

Given that the filter has Bessel characteristics, I'm curious as to why you'd want to know (or care) whether it's implemented by FIR or IIR?
