For APM2 only, you'll need to make your own cable following the pin definitions in the electronic manual. The ADAU1701 board apm2 pairs with the APM3 expansion board. The default program is 3-out, which is used to achieve a 2.1 system . For four outputs, buy the BDSP2.4U, or use the ICP5 board to modify the default program and make your own wiring connections. APM2 (AA-AP23122) is a 2 x in, 4x out DSP kernel board based on high performance chip – ADAU1701. With the integrated DSP chip, APM2 can be applied to various DIY audio, commercial or industrial applications such as digital crossover, bass enhancement, loudspeakers, kiosk, etc. After connection with WONDOM programmer – ICP series, APM2 supports programming with SigmaStudio, remote control through PC UI.

Package Include 1pc AA-AP23122, APM2 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: Looks decent, but no specialized connectors are supplied - 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. ## Features - APM2 (AA-AP23122) is a 2 x in, 4x out DSP kernel board based on high performance chip – ADAU1701.

Have a look on youtube for sigmastudio and your wondom board. Also, there are some forums about "how to" make your own programe/settings for adau 1701 processor. Good luck! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just what I needed!
