I just picked up a Crown USM 810 digital mixer and popped it open to notice it has 4 of the older ADSP-21065L sharcs in it...apparently this digital mixer does 32 bit floating point processing(it also does 24/48 ADDA) in an 8 x8 matrix...I( am not familiar with the CNET system it uses)...at any rate I was wondering about the quality of these processors according to the manual:
Different filter types include Low-Pass
Crossover Filter (1st-4th order), High-Pass
Crossover Filter (1st-4th order), Parametric
Equalization Filter (2nd order), Low-Pass
Equalization Filter (2nd order), High-Pass
Equalization Filter (2nd order), Low-Pass
Shelving Equalization (1st order) and HighPass
Shelving Equalization (1st order). 32
filters per DSP processor are available for a
total of 128 filters within the IQ-USM 810."
I am waiting for a usb>RS232 and a DB37f solder terminal to come in the mail so I can experiment ...it does use older 3 pin male barrier block cable connectors so I gotta find an appropriate replacement and solder some stuff together...I only paid $50 for this so its not like I am expecting much out of it...but there might be a nugget or two to be found in digging around in the filters...
