Hi Moritz.

Very cool .... this is sounding better all the time. We
should be able to make a system comprable to the $3500
procomp for 10% of that price.

I see 6 pins on the 34-pin connector labeled ADC 0-5
that use all available ADC ports on the AT90S4433.
Is this for the six potential channels, but only two
are in use by the single amp board?
Wow, the specs on this uC are indeed impressive. 15k
samples per second, conversion time of 65-260 micro
seconds. And it uses <15mA at 5V running 8Mhz. I
should have went with Atmel RISC long ago. I can't
believe how cheap these are.
