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. ## Features - 2CKT RCA input, 3CKT RCA output - 1CKT AUX input, 1CKT AUX output - 1CKT molex Micro-Fit input, 1CKT molex - Micro-Fit output, - Powered by DSP kernel board ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07HHNZ44R | | Best Sellers Rank | #66,365 in Electronics ( See Top 100 in Electronics ) #1,100 in Home Theater Audio | | Customer Reviews | 4.2 4.2 out of 5 stars (10) | | Date First Available | September 20, 2018 | | Item Weight | 3.17 ounces | | Item model number | AA-AA11428 | | Manufacturer | Sure Electronics | | Package Dimensions | 5.71 x 3.9 x 1.89 inches | ## Images ![2 x in, 3 x Out Digital Signal Processor Extension Board for DSP - Image 1](https://m.media-amazon.com/images/I/71eYnQvNR3L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just what I needed! 10/10! *by A***R on 7 October 2025* I got all three boards, the dsp, the programmer and the i/o board.

Fast shipping. ### ⭐⭐⭐⭐ 3 out, but what about 4? *by N***C on 5 August 2026* DSP outputs 4 channels while this gives access to 3. It is honest in advertising, but has this shortcoming. Works, but I ended up wiring directly to the DSP with connectors. ## Frequently Bought Together - 2 x in, 3 x Out Digital Signal Processor Extension Board for DSP - 2 in 4 Out Audio Digital Signal Processor DSP Kernal Board - ADAU1701 Supports Adjusting Gain EQ Crossover and Time Alignment --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/675937578-2-x-in-3-x-out-digital-signal-processor-extension](https://www.desertcart.be/products/675937578-2-x-in-3-x-out-digital-signal-processor-extension) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-11-07*
