I’ve been running this DSP on my motorcycle since 2019 and no one could explain how to properly use it. This video is extremely useful, thank you.
Literally can't think of a more absolutely pointless and useless endeavor by putting a DSP on a motorcycle! 😂
@@skypallman6169 you obviously don’t know about motorcycle audio competitions. You should check it out, then you’ll understand the need for a DSP on a motorcycle.
Bout to put one on my motorcycle too
I’m curious Where did you mount it, so that you could access it? Thanks! I’m considering this one for my system
Best Unit I Ever Used, Super Easy & Super Clean. I Definitely Highly Recommend It.
Just bought one. I am waiting for it to arrive. I am excited to get it installed. Many features.
Good run-through of the features. Looks pretty good for the price. What's missing here is the depth of audio processing that will give the ability to tune a system fully flat. What I mean is, a 15 band graphic EQ is limited. A single band parametric EQ only let's you fix one problem area. A very good DSP will have 30 band graphic EQ and minimum of 10 parametric EQ filters. I would pay double the price of this for the same interface design but with more processing. in some cases the ability to program via an app or PC is a must. However, sometime simple is better. i like the simple all in one design of the 2.8X. I am not bashing this DSP unit. I think the price is affordable and I'm going to get one for use on my workbench for testing.
and did you get one? whats your thoughts a year later?
Not sure how i didn’t find you before cos I have been looking for a decent instruction video. Thank you 🙏
i had mine installed wrong all this time, i had split my sub and mid RCA's and put them in a b. it played very well just needed some tuning. after watching this video and re installing the correct way, i cant get my mids or highs to play. help is very much needed
This is a very helpful video well explained. Also this equipment is very useful in car audio system.
It’s been a year let’s see those other videos you said you would make about measuring for delay this would be helpful with my Stunt wall
Thank you for this video. Very helpful.
Just about to install one of these, this is super helpful!
HOW DO YOU LIKE IT SO FAR?
WHAT IS YOUR SYSTEM SETUP?
@@stillrumone love it, very customizable! Go to my channel, I have some videos of the setup in the most recent ones. I would buy again in a heartbeat.
Definitely gonna send a ton of people over here for this video
Thank you, I needed that
Thx for this video, I'm looking for this one.
Great video. Now time to install one on my car.
This seems like a well-sorted device.
I just bought the ndy500 neos from parts express and WOW!! Im buyin this next im sold on prv!
That is great to hear !!
Great video 👍 were you able to make any more videos with this dsp
I like this. But what's the volt output for RCA's?
Ahhh never been so excited.
Thank you.
I amazoned it today.otw
Thank u thank u
What do you think? Any hiss noise?
@@makhailasharria
So clean!!!!
Perfection.the final piece.
My “flux capacitor”
You mentioned output signal saturation if the lights blink. Can you explain how this can be remedied?
Question on the 2.4x: Can you run 1 channel on stereo and have left/right fading? Or do you have to use a 2.8x to fade left to right?
Nice! I’ve been wanting a dsp but shy’d away from trying to install it. Thanks!
Thankyou Sir!. Is it possible to configure my subwoofers to selectively receive specific bass frequency ranges, such as 30-60 Hz and 120-160 Hz, using the DSP?
So, if you ran one DSP FOR THE LEFT AND ONE DSP FOR THE RIGHT would that create a stereo sound instead of a MONO sound? Or is that even necessary? Update, I just got this yesterday! Pictures, videos, do it no justice. It's really a nice unit!
I have a amp installed on my harley in which the amp gains (crossovers) are already set from the factory. I'm about to add some subs ,Would my speakers still benefit from this module?
We need more video about this product
Where are the other in depth videos on this unit. I bought one and just need some crossover tips.
I was thinking of getting 2 of these. So I can run rca cables from my rear speaker and one from my front speaker rca out. Have one for the amps for my tweets and the other one going to my Amp for the mids. Have 8 6.5" mids and 8 horn tweets.
That makes no sense bruh. You only need one set of input.
So basically if I use this I can eliminate the equalizer I have and the cross over because this dap is 2 in one am I right
Actually could I run the right rca from my head unit front and left rca from rear head unit rear. I just want more control from my head unit for my tweets and mids. Going to have them on separate amps.
If using a stock head unit with a LOC can I just wire this up in line with the LOC like say for instance... Head unit to LOC to DSP to Amplifier reason I'm asking is I don't know much about installing and everything is already installed and working I'm just wanting to add this to clean up the signal for better clarity
Can you adjust all this with a phone or computer
Just bought a DSP2.4 for a home audio system. The idea was to use it to feed six audio amplifiers for a set of three-way speakers, and one more channel for subwoofer output. So I need this DSP unit to first send A signal four ways into the red RCAs of the four outputs, and B signal to the white RCA's four-way also, before crossovers and EQ's were configured. Is it possible with this 2.4 unit?
Is that time delay video planned for anytime soon?
I have 4 amplifiers and there is only 3 sequencers so now i have 3 sequencers to 3 different amplifiers and then i took remote from one amp to the other amp but that is okay? Nothing will brake? (:
Did you make a video doing a deeper dive into how to set the limiter because I can't find it. Thanks
Still waiting on that
I have a PRV SC-20FT Pro 2 Channel RCA cable and I also bought this DSP. Being that the DSP only has 2 inputs… which output on my head unit do I plug the RCAs into?
Front, Rear or Sub out? Or do I need Y splitters? If so, how do you recommend I wire the head unit and DSP for optimal performance?
Front channels
@@drzflyest4 really don't matter front ir rear. Just not the sub
@@PeterFeltersnatch852 it certainly does matter as some had units may not put out s full signal to the rear
Wanted to know what is the voltage range for preamp inputs going into amps this can set?
That will be up to you, you can control the output on the unit - you can set the desire voltage to your amplifiers, you always recommended to set the gain on the amplifier at half the way and control on the signal on the DSP
how are u making sure that the amp out put to speaker, is actually sending the signal, freq, that u set on the dsp ? my amps don't have a pass thru, so, how am I supposed to set the frequency at the amp ? To not go against the dsp, frequency?
Make sure any crossover on the amp is fully open. If you have a full range switch make sure it's on full range. No bass boost.
Is it possible to use both parametric and graphic equalizer?
Yes you can use both. Parametric is for one output, graphic is for all outputs
I have 4 MR800.NDY 8inch 8ohm prv and I’m using a 3k taramps……. What do you recommend me setting my DSP 2.8x hpf and lpf
we do not have a MR800-NDY model, but all our models have its recommended crossover point on our website
Would i need 6 outs to use this with a 4 channel amp and a subwoofer amp using 1 subwoofer ?
The settings that are saved, do they stay when the Battery is removed from the vehicle or do you have to set it all over again when power is removed
This unit will automatically save changes that are made, in real time. The memory saves forever even if you remove power.
@@PRVAudio I probably have a older model then because mine looses memory when the car dies and I have to reinput my settings
How would I run this to two mono amps that are gain matched?
If I were to run this with my Pioneer 80prs which can be run in active mode, what would I set the head unit to ?
And would I set my amps on full pass?
If you are running this DSP on your system, you should manager all setting for your subwoofer on this unit - which you will need to set a HPF and LPF for that channel
I have 14 speakers. 5 per door, and 2 per A pillar. Now could I use two of these in stereo? Run 1 run to 1 and use 7 outputs on left and same on the other but make it right? Or could I take front dash L with door R and front dash R with door L that way I’m using the left and right on BOTH?
yes
Currently have a 2021 challenger with the stock head unit I’m running 2 amps and a battery pack with 2 kicker 12s all ds18 on the mids and highs I already have a converter the lc6 or 7 can’t remember would I need this if I already have a converter ?
a DSP is always needed in any system
My first two channels are for my front door 6x9s that are ran in parallel with the dash tweeters. What do you suggest the settings be for that? I want some mid bass up front but don’t want to blow the tweets. Please help. 6x9’s are JBL GTO939 100 watts rms each. Tweets are Skar 3.5 150 watts rms.
Sorry bud but you’ll need components for any real bass. You’ll also have to connect a crossover rewiring the tweeter to not cross over LF only HI look up Car Dash Tweeter Speaker Wiring Harness automatically plugs in
Can you put a HPF and LPF on the same channel to bandpass?
I wonder this too
I'm learning.
Did u say i can set the frequencies of each output separately. I.e it can be a 8 way crossover?
Yes. 8 individually programmable. Its unbelievable what amazing tech is available at an affordable price.
With this dps can I run 2 Prv SQ6000 1 tuned for my Mid Bass the other with my Subs ? If yes how do I pair that with my Pioneer Head unit where the out going RCA is "front " "rear" "sub"
the PRV DSP 2.8X is a great option you can use the either connection from you radio ( to your prefer ) you will just need to route the input signal to the right output channel for the subwoofer amplifiers
Can u tell what good crossover to 😮 put a set deaf bonce Sylvesters 6.5 midrange speakers they don’t like to much bass, I listen to a lot of rap music?
Si tengo 2 set de conponentes para la parte frontal y para la parte posterior y quiero saber si puedo usar un canal para mid bass y twiter por cada puerta más tengo 2 subwofer de 8" eso se estará conectando a un aplificador pioneer de 4 canales de 1,200w y a otro amp para los subwofer rockfod fosgate R2 500x1 funcionará bien
I just bought one of these, I'm wondering with only one pair of inputs how would someone get the rear channels to work? It seems the functionality is focused on purely highs, mids & lows and maybe some stereo if you want.
Highs, mids and lows... Can't do more than them 😂
it takes a left and right rca signal and multiples it 8xs. so you can set it up multiple ways 1 and 2 front left & right 3&4 can be rear left and right the turn the gains up and down if you needed to fade front &back
Tim, thank you for this video. I purchased the Stetsom first then sent it back and purchased the PRV 2.8 because of this video. When are you going to do a video on the delay function? I have my measurements from the front of the drivers to the center of the driver's seat but I am not sure how to input everything. Looking forward to learning more about this DSP. Note: I have noticed little pops, chirps and hisses in my system since installing this DSP. Same with the Stetsom. Is this a common problem?
The signal from this unit is strong so you may hear things that are suppressed in others. For the delay simply convert inches that you've mesured to cm. Start with the coil furthest back and go to the output that's on the next forward component and delay. Continue like this.
@@PRVAudio do we input the difference in distance? For example if my sub is 100cm away but my driver side is only 40 and passenger is 70. Would i put it 60 and 30 respectively?
QUESTION All the features on the 8ch or the same on the 4ch??
Yes they are the same
I have a 3pair rca radio front rear sub.can i use the front or rear output?
you can use either one, to your preference, and then you can set all frequency range to each channel on the DSP
What is the ideal sound system consisting of installed in a Harley-Davidson Tri Glide Ultra TRIKE
Why would you even bother? It's not like you are going to hear it. I would suggest a helmet with headphones, that is about the only way. I have heard Harleys go down my street with the 'stereo' trying to blare out anything that can be heard over the raucousness and they sound HORRIBLE. My guess, without measuring, would be that the THD is about 90%.
@@MrJdsenior even though I'm old I still like to cruise have you ever heard of parking lot pimp this is something people used to do was to have a cool vehicle with the sound system thank you for your comment but this section is for people who like to play the music loud you can get your earbuds and get off this platform with those kind of comments Boomer LoL 🤣😆🤣
what does the bt and lr portion actually do
Does the 2.4 not have the preset xover feature?
how do you save your settings to memory?
It should be fine if the alternator puts out 14.2 volts? The prv should handle this amount of voltage?
it can handle up to 16v input on the battery wire
I’ve ran them at 17v no problem
can you adjust 1 door speaker hpf or lpf at a time or 1 and 2 channels
yes
This also Apply’s for the prv 2.4x correct?
Correct, both have the same system
@@PRVAudio can I set channel 1 as A and B? For example I would like to crossover my 6.5s at 100hz on A. And my 8s on B at 80hz
You guys have to do some amp dynos on that 15K and that 11k/9k
Yes, they are available on our facebook and instagram page
Been fussing with the sequencer function. And the dsp won't auto sequence. What am I missing..
Tim i cant come out with these settings
So i can get a decent head unit "android unit" which has a decent eq tuning most of the time and this with amps and get rid of an normal eq and crossover i suppose.
Might be harder to get used to it but at the end of the day you save up some $$ and this does the same job
My verry expensive pioneer head unit have so many dsp type features
yes, but you do not have the options for multiple amplifiers like one this unit , 8 channel
Is pre-amp still needing with this dip?
If you need the extra quick adjustment option, you can can use it
When I use the output eq it affects all the frequencies... If I change 30hz up 1 db every single other frequency goes up 1 db... If I change the Q every other frequency changes to the same Q... what I got from this is that you can specifically change individual frequencies but it seems like it changes all of them when I do just one. Also does it on the input eq when I up the db to one frequency it does it to all the frequencies...
The output Eq - has a Q setting - this value will determine how wide the frequency peak will be - the lower the number the wider the range is ( which it will affect all frequencies around your peak frequency set
Could I use this if I’m only using one amp for the sub
What would be the benefit of using this
@@rubbensofficial5511 if you watched the video it has other uses besides processing.
Tim give some info how to use the expert px2
Hifi Vector did one on that dsp
saya dari indonesia bagaimana caranya untuk membeli produk ini ??
I seen it had a hpf, but does it gave a LPF?
Yes
I must have pressed something in the thing and it won't save the x over settings in the individual channels... Something is overriding it.... Example if I goto xover output 3 change it to low pass 80hz bt12db.... When I click away then go back to output 3 its back to hpf off
Could you use this on any company's amplifiers ?
Yes.. but I'm sure they or any of those sister Brazilian companies would like that you use their amps instead.. but they would work for any amp...
Thank you ! I have crescendo amps
Amigo yo tengo 2 set de conponentes para la parte delantera y para la parte tracera y son sus tweeters crrosobers y los speakes más 2 subwofers de 8" para una tacoma 2003 puedo poner 1 canal para la puerta del conductor 1 para el pasajero 1 para la puerta posterior del conductor 1 para la puerta posterior del pasajero serian 4 y 2canales individuales para lós subwofer y aparte de eso tengo que eliminar los crosobers que traen los conponentes o sequedan
you are very knowledgeable about the device itself and how to work around the settings, but you explained in the input parametric eq wrong, specifically the Q-Factor the tighter or the lower the value the more that will affect neighboring frequencies and the looser or higher the number the the less that will spread and affect neighboring frequencies. if you want to cut 63hz frequency or boosted without affecting 50hz or 80hz you will choose a higher number... but if you want round out more evenly and lower or boost everything around the 63hz you will go with a smaller number.
Would love if these came with a subsonic filter
So any channel you choose to be a subwoofer Channel, well it's high pass filter is a subsonic filter... Same thing bubs... High pass filter = subsonic filter in a subwoofer crossover/settings... No biggie.. it's all a learning experience
@@josegiraldez6230 so i can use the hpf and lpf on a channel at the same time?
@@banlmao1707 my DSP has a bandpass filter so I can use both.. I don't know if this one has one and I didn't think about that so my bad, anyways I always use the subsonic filter on the amplifier anyways.. no need to use it on the DSP ,but yeah now that I think about it, it would be cool to have just a dedicated subsonic filter on a DSP.. I guess you're right....and the bandpass that I am speaking of I usually use on my mids and highs anyways, so once again and as I said, it's always a learning experience now for myself....
@@josegiraldez6230 I’m assuming by using the low pass and high pass at the same time it’s basically a bandpass option, and I can set the hpf as low as I want so it would be a subsonic filter
@@banlmao1707 yes sir..
yo, the larger the q, the more narrow the bandwidth is bro. 1 octaves = 1.414. 2 octaves Q = .667 the lower the Q, the broader the bandwidth curve of frequencies become, affecting more frequencies. the higher the Q, the more narrow the bandwidth curve of frequencies become, affecting less frequencies
That is correct, on the Output EQ for each channel your will have an option to set the Q value
I want to know why he said nothing about LPF. Since I am trying to set my DSP for my subs and I have no idea how to best set it
what is BT and LR?
Was wondering the same. I figured he meant slope
How do i set the band pass

Bluetooth?
Seriously, every single video I watch just skips over the save feature, and I've watched several. Does it even work? I have tried to save and all I get is some stupid screen where they want a name input. I can't get past this to the actual save. Could you PLEASE tell me how to do this? I emailed the manufacturer this question and cue the crickets. I can't find it on google, YT, the manual, or anywhere else. PLEASE HELP.
There is no saving - everything is saved as soon you set it! You can save different profiles but when you are doing adjustment whatever is set is saved already! even if you unplug the units all the settings will be saved when you turn it on back again.
When naming the save, the arrow pointing right will end the naming input selection and save the profile
nice to see a DSP that doesn't require a laptop to use! having said that, there are things that could be better. ditch the stupid EQ presets, and use the processor power for more EQ bands. if you want SQ, a digital input of some kind is needed. a port for an (extra cost)external display would be a nice, allowing you to set the system from the driver's seat. all in all, looks excellent for the price.
You can do just that with the new Stetsom Dsp the have a remote display you put it where you want. And they have Bluetooth now
Does it have EQ settings?
did you not watch the video
???
😂🤦🏼♂️
Hello Sar
Why all my lights red on mines now
been a month, still red?
No Bluetooth capability?
thank gawd, no
Ooo hell no way to complicated for me 😮
a few button clicks is too complicated? How do you use a microwave?
Time to rethink your life then😂
Why a suqence to shut off n power on amps? Thats what there remote wires are for
Either way im buying one so i can connect more amps to my radio sense its got one set of inputs of rcas from the dsp to the radio and 8 outputs 🤙
@@joshjorgensen2002 using the sequencer on the DSP allows you to control when and how the amplifier turn on and off, some radio just turn off very fast, while the DSP is still on the amplifier as well causing, and boom noise when you turn it off, the sequencer will allow you to eliminate this and have better control on your system
Same model as stetsom dsp
But stetsom don’t explain how to use it in English
Stetsom actually the one that makes it. Prv is just rebranded they both come out of the same build house.
I called tech support, there's so much here. I need help, they said watch this video, I'm feeling I'm going to be trying for weeks to figure this out. Not many shops in my area, that deal with dsp tuning. Do you offer over the phone, help me tune for a fee ?
What are you trying to do?
It's complicated when you don't have anything hooked up
Idk why this looks so much like the Stetsom dsp.....😳😳😳😳😳😳😳
Because it is just rebranded they come from the same build house
So you going to read the manual for 2 hours just to set this thing up once way too much stuff going on for the average consumer.
To dam difficult to understand I bought one and I have to sell it back
No Bluetooth.
