I was just looking for information on this dsp this morning lol… you gotta be some kind of wizard

[@slowbrezze]

the Ai is Ai ing lol

[@62dobie]

Thanks. You gave the most in-depth explanation I’ve heard so far.

[@RAW-CAt]

More to come😉

[@stormyyoung6344]

Thanks for explaining everything where I can understand it.👍

[@christiandshatto7765]

Thanks(30 years experience, lol) my audison apf8.9 bit had noise gate, and I never truly understood it/did, till your explanation now. ( I should've known that)

[@roughboygarage1475]

Thanks for the great overview. Explained so that even i understood it. I have a bunch of questions, but I'll save them for after I'm caught up on your videos. All save for one, after description. Im putting together a system comprised of new and old components. I have a Kenwood Excelon headunit (5v output), chosen for the x overs, eq, and time alignment. It will be running to 4 old school Phoenix Gold amps that are like (100mv-2v input). I didnt realize until recently that the high voltage headunit may be too much for the amps. Ive been out or car audio for the past 30yrs. Back then 1.5-2v preout was the norm unless you had a high dollar line driver. I have been looking into modifying the amps. Barevids or EARS mentioned it in a video but i cant find it. I have to replace the caps and service them anyway so id be right there. Would a DSP such as this allow me to run the amps unmodified? Or should i just modify the amps or both? Thanks for any input you can give on this or a video you can point me to better explaining signal voltage.

[@valentinguz]

Thanks for helping around ❤😅

[@bugman72]

The shutdown delay option in the DSP is useful if your system has "turn-off pop". Setting a shutdown delay on the DSP allows the amps to turn off before the DSP and will eliminate (generally speaking) the "pop" you may hear when turning the ignition off.

[@DonnyDonnMendoza]

Great info.

[@4BeatBox4]

Great video 🎉😊

[@ecpruthless]

Good vid, these budget DSP's are getting pretty good. so are the 31 bands of PEQ for the input signal(like most budget DSPs), or individually for each output(like minidsp and helix)? I just assumed the 31 bands are shared for all channels, but @33:09 it looks possible they might be individual output EQs, which would be pretty cool

[@evilinside5984]

This unit has the ability to set 31 bands per ch./speaker.

[@ecpruthless]

@@evilinside5984 if thats true, im impressed for $280

[@christ1431]

Love your videos, thank you. Without having the dsp to actually test, how do you think this dsp would compare with a Helix .3? I have a Helix in for repair but am debating getting a D4S because most of my equipment is D4S.

[@RAW-CAt]

I would say this d4s DSP is amazing for the price and for the target audience. It's "basic" in it's functionality, however it has everything that you might need. I assume the BT performance will be quite poor as in all cheap DSPs. 48kHz sample rate is limiting as well compared to Helix 96kHz. Build quality and reliability however should be on par with Helix, as you need to build robust gear for bassheads.

[@julesbruchez-theartofgrapp9646]

@@RAW-CAtbest cheap option is the Alpine c60.

[@purplehazeffc]

Will you be able to do the EQing on REW & then import the files into the DSP?? Like you can with Helix for example.

[@RAW-CAt]

No. Not many DSPs support direct importing from REW. I believe it's only Helix, Mosconni and Audison from recently.

[@ralphlongo1975]

@@RAW-CAt MiniDSP too, but their car audio offerings are becoming few.

[@ssamanta72]

Is there a video for Alpine PXE R500 tuning. Please help.

[@RAW-CAt]

I have one comparing Alpine software against Helix.

[@bradmeek]

greats minds thing alike ive been debating whether to get a line driver for my alpine 850s dsp or swap it out for another dsp and the d4s was an option can anyone tell me what the 0.0V below the channels on the EQ is for? my guess is an inbuilt voltmeter, that would be a SHUT UP AND TAKE MY MONEY feature 100%

[@RAW-CAt]

I would imagine that is input sensitivity and it has something to do with the limiter. But I am just guessing here.

[@bradmeek]

Ive been informed its a basic output voltage reading

[@RAW-CAt]

@@bradmeek yeah, Drew actually has one so he tested it live.

[@666nacirema666]

I wonder how the actual dsp measures? Do you happen to know what chip its using?

[@RAW-CAt]

No, unfortunately I couldn't get one to test.

[@kyleamorris]

Does it have the ability for granular phase adjustment?

[@evilinside5984]

This unit can adj. phase, per ch./per speaker.

[@JasonWW2000]

Yes, specs say 0 to 360 degrees. (Edit- on the 12 channel model)

[@RAW-CAt]

No, it's only 0 or 180. There is no phase slider. However you have all pass filters that you can utilise.

[@JasonWW2000]

​@@RAW-CAtI notice the specs on the 8 channel say nothing about phase. On the 12 channel it says "Phase and Delay Adjustment: Each channel can be finely tuned for phase (0° to 360°) and delay (up to 20ms, 692 cm, 273 inches)." So it seems as if there are definite differences between their two dsps.

[@alexdantzler8236]

Awesomeness³

[@RAW-CAt]

More cocome😉

[@1VIPWRX]

Finally

[@JasonWW2000]

Their 12 channel looks pretty good. 4v in and 4v out. Has anyone seen what the controller looks like?

[@RAW-CAt]

It should be 8V as in the specs it's 12Vpp.

[@JasonWW2000]

​@@RAW-CAt12v peak to peak is 4.2v rms. Cut the 12v in half, so 6v and then find the rms which is roughly 70%.

[@RAW-CAt]

​@@JasonWW2000yeah, you are right, my bad👍

[@johnd5542]

Has anyone tested these dsp as far as SQ?

[@johnd5542]

If Helix and Dayton Dsp's had a baby.....

[@dwightstebner2345]

Can this software be downloaded?

[@RAW-CAt]

You can find it on D4S webpage under the EZY dsp listing. Free to download and you can play with it even without a DSP.

[@ralphlongo1975]

Has anyone measured this on Distortion Factory?

[@RAW-CAt]

Yes, Drew dit it. You can find the measurements here: facebook.com/share/p/nDxkdwjTQ5Un74zV/

[@ralphlongo1975]

@@RAW-CAt It looks like we probably have a new budget leader DSP

[@RAW-CAt]

@@ralphlongo1975 I would tend to agree. Especially now while they are runing the promotion price.

[@ralphlongo1975]

@@RAW-CAt oh, didn't realize it was a promotion price unit, dammit, 600 dollars will put it in a very different league that it won't be worth. Maybe the 400 dollar rage, 600 gets you into Helix/MiniDSP 8x12 range

[@constantinelheman]

Looks similar to Alpine’s software

[@smurfeco2.358]

Looks like a copy of alpines software

[@JasonWW2000]

They look similar, I wouldn't assume that one is a copy of the other, though.

[@smurfeco2.358]

@JasonWW2000 well obviously not a " copy" but it's there lol

[@RAW-CAt]

All chinese DSPs share the same basic software with different "skins". Saves some money for the manufacturer that doesn't need to develop custom software.

[@die_news]

hello Sir, does it have an option to import .txt like helix does? thanks!

[@RAW-CAt]

No, it does not.
