Learn how to use the PRV Audio DSP 2.8X (Digital Signal Processor)

[@dlcarburetor]

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.

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

[@fatboy9725]

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

[@PRVAudio]

That is correct, on the Output EQ for each channel your will have an option to set the Q value

[@kynghype9715]

Can you put a HPF and LPF on the same channel to bandpass?

[@BSA210]

I wonder this too

[@MrMan-ol4ic]

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!

[@cwtoo]

You mentioned output signal saturation if the lights blink. Can you explain how this can be remedied?

[@stevensamaroo]

Is it possible to use both parametric and graphic equalizer?

[@PRVAudio]

Yes you can use both. Parametric is for one output, graphic is for all outputs

Not sure how i didn’t find you before cos I have been looking for a decent instruction video. Thank you 🙏

[@PanamaPete]

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.

[@banlmao1707]

the "master volume" feature is what changes output voltage from 0v to 5.6v max, it will be clean all the way through as long as ur input to the dsp is clean

[@yougod7253]

Wanted to know what is the voltage range for preamp inputs going into amps this can set?

[@PRVAudio]

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

Seriously, every single video I watch just skips over the save feature, and I've watched several. Does it even work?

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.

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.

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

a DSP is always needed in any system

[@bk2life]

been using a 2.8 for a couple of months now. This morning while driving to work channels 1 and 2 emitted a 'tone' id guess about 5kz at high volume. I could not turn it off. if i turned my radio vlume down it did not matter, as i have narrowed it down to the actual DSP sending out the signal. I was luckily enough able to safely get to the side of the road and tunr the vehicle off. When i restarted the vehicle, and when number 1 amp turned on (channel 1/2) the tone came back on and i had to go into setting and turn the amp off. this was so loud i could smell my voice coils. So not only are my ears ringing, huge headache, i probably have burnt up mid/tweets because of it. How do i get this fixed? And how do i know this will never happen again? @PRVAudioBrazil @PRVAudio @PRV

[@PRVAudio]

this is a unique case, we never heard this behavior, the DSP can not even respond this low ... we are not sure what happened but usually the DSP only amplifiers noise and signal from other sources, try to remove the inputs from the DSP if the noise stops, it is not coming from it, We would recommended also to troubleshoot the RCA, A lot RCA can break with vibration
