Little overview of the 10 channel dsp I bought from Ali express 3 years ago. It is no longer for sale but similar models and newer versions are available, this should give a ball park idea of what to expect.
This is the closest i found to what i have from the same seller. Please make sure you watch my other dsp video i uploaded last year. Somewhere around the half way point or after i discuss the issues i had with obtaining the software from the seller a.aliexpress.com/_msir9Le
They are a good bang for your buck in terms of going with multiple zones and size speakers, more if you get an RTA tune it can level the sound fairly well. In comparison my audiocontrol DM 810 did an excellent job at flattening my audio curve this lacked the ability to cut or boost the surrounding frequencies like the audiocontrol can as this one predominantly boosts and cuts the selected frequency without much movement in the surrounding freequencies, IE cut 300 hz to -3 DB 250 and 350 would still be at 0 db. I will say even with that I was able to achieve about 90% of the curve of the audiocontrol.
If it came with a model number I'd give it to you. The only thing in regards to model was 6 in 10 out if that helps. The seller I bought it from no longer has them but I have seen similar models for sale judging from design
