Review: Just what I needed! Took a little effort to figure out programming at first, but 10/10! - I got all three boards, the dsp, the programmer and the i/o board. I am just using this one to do the dsp for my home audio sub. But it ended up being so good, I think I'm about to buy several more. For designers or diy type guys, this couldn't be better. Works perfectly as I was hoping it would. Fully programmable for however you need it. Programming was difficult, I'm not going to lie. Every single dip switch had to be set to the opposite of what the instructions and ai said it should be. Once I figured that out with a bunch of trial and error, then it was pretty much as the instructions said. But it took me a minute to figure that out first. Hopefully this info saves someone else a couple of hours. I wish I'd caught it earlier. The Miumax program from Wondom works very well and has MOST every setting you'll need. It is considerably easier than SigmaStudios. If you can get what you need done with this, I’d recommend doing that. Learning SigmaStudios was not an easy step. But it does give you a lot more control. Those are your two options to program this and they both worked 100% correctly for me. Once you flash it to the ICP5 (it says icp5, but it also seems to write the dsp board in this step) you can disconnect the icp5 and run the dsp and I/O board without the icp5. I really hope this helps out and gives anyone considering this the confidence to grab the 3 boards and go for it. Worked beautifully for my first project using this. !0/10 WOULD RECOMMEND! Going to buy two more this week.
Review: Very good price / quality ratio. - Product as described. Very good quality. Fast shipping.

Product as described. Very good quality. Fast shipping.

### ⭐⭐⭐⭐⭐ Love these boards
*by A***R on February 19, 2020*

These are great but I wouldn't recommend them for anyone who's never done electronics, audio mixing, or dsp workflows. If you can figure out sigma studio then these are wonderful to play with and use. Download sigma studio and see if you can figure it out. If that's easy for you then these are even easier. It took me forever to figure out how to hook these up without having to buy the RCA expansion board. The trick is to get a 10 pin jst ph 2.0 wire connector harness. Amazon sells them. Just cut the double ended ones in half and you can connect to just about anything. Much cheaper. I love the extension board, but there are times I just need to connect a few things and adding 50% to the cost of the project just for connectors seems like overkill. Would probably work for the Dayton relabled boards as well.
