I am interested in the preamp board. Where can I find more info onthe pre amp board e.g. opt 1, opt 2 etc? I could not find any info on the the old EBay page on the preamp. Also, What are the prices for the boards in this GB? I know some people that may be interested. Thanks!

Regards,

Allan

I read through the PDF about the preamp, but still couldn't find much info. For example, why are there 4 outputs? How are these 4 outputs configured? For a stereo system, which one is right and which is left? How are the treble and bass control set up and what are their tone profile? Does the DSP chip have to be reprogrammed to set up the preamp for use? Does one have to know how to use the Sigma Studio/SigmaDSP software to use this preamp? Is the Bluetooth plug and play (just pair up with my phone)?

Not sure whether this is the right place to ask the questions. It would be much appreciated if 3e can supply more info.

Regards,
