8ch DSP on a shoestring? (SURE WONDOM AA-AB41173)

[NotInYourHead]

The Sure Wondom AA-AB41173 is essentially a multi-channel DAC with USB input. A Bravo SA9128 chip provides USB input, as well as 4 I2S outputs for the bottom board. A connector then routes the I2S signals to four PCM 5121s and provides eight output channels. You only need to provide 5V and data through a Type-C cable from your PC.

Now, the special thing here is: there's complete freedom to set up your system. You can use the I2S outputs, combined with Sure's TAS amplifiers, to create fully digital systems. On the other hand, there are 4 stereo analog outputs powered by quality PCM DACs. You're not tied to a particular amplifier, which is a problem I find with DIY DSP amplifier combos.

Even better, the icing on top of the cake is that it's only going for $55 (shipping and taxes not included). 8-channel DSP at this price point is INSANE. I think Sure Wondom made something wonderful that really scratches the itch for budget multichannel DSP.

The only 2 caveats I have are: is 5V from a USB port sufficient (and clean) to drive such a complicated circuit? And you're tied to a PC for DSP adjustments. Personally, I listen to music from a desktop setup, so no biggie, but what if you don't want PC clutter? Maybe a Raspberry Pi could be used for wireless streaming?

If I understand correctly, this is only a converter and not a DSP.
To add DSP functions, you will need something like an ADAU 1466 Board, for example, additionally

Could be a nice complement to this diy project for a budget DSP!

There is no DSP, only signal transport / conversion, so no PC involved unless that is your music source. In which case that may as well be your convolver too, before using this, if you even need it for output conversion.

Input is USB Audio Class 2.0 , up to 8 channels (7.1 digital stream)

48-kHz/24-bit only

It can either CONVERT (DDC function) to 4x I2S pairs

or decode to 8 analog channels (7.1 DAC) unbalanced single-ended only, max 1V only? user manual shows dip switches have four levels so I assume 2- maybe even 4V

Yes of course tremendous value - if you even need it for output conversion.


Anyone considering it, have it drop shipped to Amir for testing - ask him first!

ADAU1452-based "BEAYEAU" M26DSP from China, not cheap - any good?

M26DSP ADAU1452 Audio Processor 2 in 6 Out USB QCC3084 Bluetooth XLR/RCA Coaxial /fiber Input - https://a.aliexpress.com/_mKiL9Vj DSP noob here please ELI5 Use cases include crossovers, general PEQ, maybe non-automated room correction? Using REW + UMIK-2 for measuring... Yes I realise...

can be really nice with raspberrypi and camilladsp
