## Description

Audio Digital Signal Processor Cardboard - Support ADAU1701 PC UI/ SigmaStudio, Support Gain EQ Crossover and Time Alignment Adjustment

Review: 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: I haven’t used it yet but I wanted to note that it doesn’t come with any of the connectors/short wires like the same part does from other sellers that I’ve bought from. If you are using it as a drop in replacement where your wiring is already setup, this won’t matter, but if it’s a new build, you’ll have to source all the specialized connectors yourself.
