Sure DSP amplifier boards
Nick and I agree with you 100%, these could be game changers. The possibilities are pretty exciting when you think about it. From what we've read, studied, and discussed so far, the ICP3 can be used one of two ways. One is basic/limited programming with it's Bluetooth app. The second way is directly hooked to the computer via usb which allows the full use of the Sigma software. Until we've actually done it, can't say for sure, but that's our interpretation so far. Hope to get this project to the top of the list soon. Thanks for checking it out.
BTW, they do offer a couple of mono amps, a 60 watt version and a 100 watt version, both with the DSP option. Unfortunately, the 100 watt wasn't in stock when I placed my order so I settled for two of the 2x50watt versions for now. SURE said it was in production and would be available again within a few weeks, so it should be there now.
I wonder if there's a way to utilize the extra outputs on the ADAU1701 for the mono DSP units. That would make them more useful.
As I've thought about this more, the stand alone DSP with extension board, 2x50 watt non-DSP amp for tweeters, and 2x100 watt non-DSP amp for woofers all inside an aluminum case would make a very flexible stereo 2-way speaker design kit. You could pick any tweeter/woofer combo you want, build an optimized box for the woofer, measure, and then easily create a crossover.
You are definitely thinking along the same lines as Nick and I. If you would like to join in on this adventure, we'd be glad to have you along. Based on Nicks current schedule and mine, I'm thinking we'll still be a few more weeks before starting to look at it more seriously. That would leave plenty of time for you to place an order with SURE in whatever configuration you might be thinking of.
Believe Nick only purchased the ICP3 and 2x50watt DSP amp, where as I purchased the ADAU1701, the ICP3 and two of the 2x50watt DSP amps. I'm also kicking around the idea of integrating these with one of the ICE amp modules for a later project.
It would be fun to join, but for now I'm going to have to pass. While managing a new job, temporary apartment, and other ongoing projects, I don't think I can take on a new project. This is something I will be following closely. I am very interested in this for a future project of living room speakers for the living room in the new house. Current rough idea is 1" Peerless corundum tweeter in SEOS 8 with 8" SB ceramic in an MLTL.
That is all I bought right now. But once I figure out Sigma, then I will be buying the rest. Then working with some of the Icepower boards on hand. To see what I can come up with. I would be cool to run a 200watt integrated subwoofer in a powered tower with a powered mtm on top running at 50watts or so.
I was looking at the Wondom DSP unit, and I realized that it requires two extension boards for a 2 in 4 out configuration. After doing some more searching, I found what could be a great option for an ADAU 1701 2 in 4 out DSP on the cheap. Just add 4 channels of amplification, and you're all set. They even have a 4x 100w amp that can power the DSP board.
