Hi all
Planning my sound furniture and would love to use a DSP.
Found the Wondom DSP and that seems like a great price.
But as a noob, I'm now in desperate need of some qualified help 🙂
So I will have an amplifier board ( ofc ) 🙂
Will the DSP be before of after the amplier ?
As I read that some people uses the DSP as cross over, I'm thinking it needs to be after. Unless I'll have a 6 channel amplifier, so I can send the signal to woofers, mid and tweeter.
I know I'm a bit over my head, but I do love the steep earning curve

Why would you want a dsp?
It is a signal processor and as such usually works on smallscale signals, ie before the power amps. In this lies one of the main benefits: the crossover / correction filters are digital instead of being expensive high power parts. While sigmastudio does the programming graphically, the learning curve to set up the environment may be a little steep. You will need the programmer as well.

Hi efuon
I would love to do a bit of correction and most of all, room correction.
So do I need to have more channels on the amp board ?
My amp board is 2x50w - but each speaker will be woofer, mid bass and tweeter. So unsure if it can correctly apply the filter when it goes though only 2 channels out.
Also with the DSP - ability to use it as Cross over, would be coo 🙂
In regards to setting up the DSP - yes need the programmer board and will be a bit hard to do - but more in my ally 🙂

correction as in speaker phase alignment, eq and xo will be not that hard, if you have the system set up.. the benefit over analog implementation will be the flexibility and easier variation of parameters (which makes it a great sketchboard IMHO)
DRC as in creating a fir-filter to convolve each speakers signal with to correct your rooms shortcomings at a single point will be much harder and potentially not as rewarding as you might imagine. room treatment or good headphones will probably do more for you.
you will need as many amp channels as you want to use it for (and have available outputs on that board). you can use the dsp just for stereo room correction which will lower complexity. but then how about trying out a pc-based solution for that before? there are some open source implementations of DRC.

Hi again
Great feedback! My sound furniture will be stereo - so a tv bench with 2 build in speakers - so the wife will love looking at it ( as she HATE the look of speakers ).
So let me be a total noob and ask:
I have a signal in ( from tv or from audio receiver - could be airplay, DNLA or similar ).
This goes into the DSP
Will the output signal, that goes through the amplifier and then to the speaker units, have the signal tweaked as I want ?
In my mind, the woofer needs one channel, Mid one channel and tweeter one channel.
But I might be wrong - I just find it hard to see if the signals are mixed up, that they can correctly go to the right driver 🙂
Would I be better to do input signal -> DSP -> AMP -> passive cross over -> driver
( and just use the DSP as filter )
I know room correction is not the answer - but our living room is combined with the kitchen, and the Sonos really had a noch up in quality after room correction.
As I want to use the set as both TV/movie sound, and also for music, I think a bit of room correction could make it 10% better ( the wife won't be able to hear it, but putting on Manowar or Metallica at high volume, might show the difference )

yes. as far as amplifier and speakers do not change it. nothing is really linear.
if the sonos system is like most automatic systems I have encountered, it will just add delays to compensate for different speaker distances at listening position as well as adjust an eq to compensate effective frequency response a little. this is both easily done with a dsp. if you are using a DSP anyway I would suggest to use it as a crossover as well.
I *think* the wondom dsp boards are "based" on these: freeDSP | An Open-Source Low-Budget Audio DSP
You will need to be able to measure for all this to make sense.
Else I would suggest getting something like a used home theater amp that has the auto-setup (I payed like 50€ for a used Onkyo 707 which came with its own measuring mic)

The usual route is -
Source - DSP as line level crossover - one amplifier channel per driver.
So for stereo 3-way speakers a 6-channel amplifier.
You remove any crossover in the speaker and connect each driver to its own amplifier channel.
Note that you will need tweeter protection if you follow this route.
