High performance speaker building has never been easier. The ZOUDIO AIO4CH combines all modern features in one easy to use and affordable module. The included wiring harness makes installation quick and reliable. The compact form factor allows for installation in nearly every speaker. Due to its high efficiency it puts out a lot more power than its size suggests. Besides long-range Bluetooth streaming, wired input is supported. The DSP allows for powerful filtering, in some cases replacing a big and expensive passive crossover altogether. Settings can easily be changed using the Windows™ configuration tool.

    Great product! Makes speaker building much easier!

    Big WOW. Coming from plug-and-play class D amplifiers, this is a whole other thing! The AIO4CH works & sounds 10x better than my previous setups after easily/quickly applying some filters in the useful configurator app.

    Seller is also super helpful, answered my question within 10 minutes. Would buy this product again without doubt for other projects in the future.

    This amp is a Gem! I can play music through it from Windows 10 or my iPhone, which ever is most convenient. Sound is exceptional and as good as my Aune T1 through tube amps – Texas Instruments really got it right in their all digital stream, word to PWM converter at the output stage. This is an amp I can live with, drives 2, 15″ FR from 100Hz up and two 4 ohm, 18″ assists from 100Hz down, does the rising response with lowering frequency for my OB mounting too! It goes as loud as I can stand listening and then some! At normal listening levels sound is transparent and staging imaging detail is quite captivating. Thanks for a great product – I’m going to order a 2nd – a true bargain for what it does for me!

    Heb in de huiskamer een dure lyngdorf 2170 met roomcorrection staan. Deze miniscule versterker klinkt net zo goed voor een fractie van de prijs. Dit is met recht een audiofiele geheimtip.

    My searching has finished. This board gives the flexibility to provide for many configurations. The 4 channels can be configured at 2.0, 2.1, 4 channel. As a maker of different speakers this flexibility is great, It give a lot of freedom in design. The Bluetooth as DSP noise floor cannot be heard. And on my OTTOPOD 2.1 speaker sounds better than an Apple Homepod. I am ready to try some more designs I can apply this board to. Thank you for a great product which up until now was not available to speaker makers.

    Greatly recommended, awesome amp for (mobile) speakers. Low power consumption, great quality. Board is small but powerful, and firmware is fully customisable. Seller is also very helpful, even fixing my AMP for free when it was broken due to user error. What more can you ask for.. Truly awesome. If there’s anything i would add to give it 6/5 stars: Maybe some documentation for the config utility, it can be a bit daunting for the less-experienced speaker builder. Also, on my iPhone setting the volume on the device does not work, it has to be controlled on the AMP (minor inconvenience). Keep up the good work.
