DSP 2.8X – Digital Audio Processor, Crossover & Equalizer – 2 Inputs & 8 Outputs
Bringing innovation and technology to the Automotive Sound market, PRV Audio launches the DSP2.8X Digital Signal Processor, capable of making various Real-time signal adjustments, from crossover filters, graphic and parametric equalization, alignment, phase inversion, limiter, audio generator, among others. Enhancing Your Audio System!
Through an LCD display and intuitive interface, it allows real-time audio adjustments. The DSP 2.8X features 2 audio inputs (A and B) and 8 independent outputs and allows you to choose the audio source (A, B or A + B) for each output. It has an integrated equalization system, with 15-band graphic equalizer, manual tuning, or through 12 presets (Flat, Loudness, Bass Boost, Mid Bass, Treble Boost, Powerful, Electronic, Rock, Hip Hop, Pop, Vocal and Pancadão).
For professional equalization adjustments, it has 1 INPUT Parametric Equalizer and 1 OUTPUT Parametric Equalizer with gain control, specific frequency setting, and equalizer bandwidth, allowing fine adjustments and detailed equalization control.
The Crossover function allows you to precisely define the cut frequencies, attenuation rates, and topology of the LowPass and HighPass filters with Butterworth and Linkwitz-Riley filters (12/18/24/36/48 dB / 8ª).
To aid in the protection of amplifiers and loudspeakers, the DSP 2.8X features a Limiter with Dynamic Attack-Release system that dynamically controls the Attack and Release parameters in real-time, providing security and sound fidelity.
In the audio treatment, it also has Alignment capabilities through High Accuracy Delay, Phase Inversion, Independent Gain by Output and Master Level. For accurate measurements and adjustments, the DSP 2.8X features an integrated Audio Generator with tone generation and frequency sweep, and Pink Noise. Configuration Copy functions between output channels.
It also has the functions of Management, Save and Load Settings in memory, Security Password that blocks the editing of the parameters, Marquee / Text Display, and Language Selection.
Sequencer Feature
Allows sequential triggering of other products through the remote trigger connection (REM). Use a cable of at least 20 AWG. The sequencer has three outputs (S1, S2, and S3) which are sequentially activated and deactivated according to the input signal from the remote input (REM IN).
The triggering interval between each output can be set from 0s to 4s. When the set time is 0s, all three outputs will be enabled and disabled at the same time after 3s of the input remote (REM IN) signal change.

Customer Reviews
Love it Thank you
This is my first dsp ever and wow the way you can tune each speaker is bad a..as you can see I got a very big system. Prv dsp freaking awesome
As owner of car audio shop we really try and push and sell PRV products and always recommend customers to put one these on with they install of thier system. It allows For some much tuneabilty
This is the Perfect Digital Sound Processor I’ve got for my personal sound system. Thanks !
I bought this as a gift for my grandson. He said he likes it
Ok, so I’ve used audio control for decades…no more! Prv dominates the processor game hands down! For the price you can’t beat it, it’s the easiest, most accurate piece I’ve used. It also cleaned up my mess of rca’s in a compact, mount anywhere package. Sorry audio control, Prv is the next generation for audio!!
Was the best money I spent so far u would have to be a complete dumb ass to not buy it
Of course the gains and crossover settings are pretty straightforward but I would like to see another video on PRV’s YouTube channel about the more advanced settings. The limiter, parametric EQ, EQ, etc. other than that I like how I don’t have to use all those rcas to run my system.
Had a small issue with a ground loop isolator blocking lower frequencies but as soon as I removed it this unit was great! Love it, still need to do time alignment but the crossovers and eq are amazing!
I think this DSP is fantastic. I have it connected to 2 Orion 750.4 amplifiers and it pounds. The only thing I suggest for future models is an optical input (Toslink) for a cleaner signal from the head unit to the PRV DSP 2.8X. I had to buy a digital to analogue converter to make it work. For audiophile's like myself If I have the option of optical over RCA I will take it every time. Right now for head units with Toslink Only Sony, Stinger and Joying have Toslink and for Amplifiers several Chinese manufacturers you have Toslink but you can only find them on AliExpress and JL Audio has an amplifier with Toslink. For DSP with Toslink input there is Audio Control, B2 Audio, Hertz, JL Audio and many others but they all charge an arm and a leg for them. Something around the $200 mark would be Ideal.
