Product Description


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!
Highlights:
- Number of processors (DSPs): 1
- Input Channels: 2
- Output Channels: 8
- Display: LCD16x2 Characters
- Built-In Remote Out ( Sequencer )
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.

- Reviewed in Canada on September 20, 2024Verified PurchaseThis makes a huge difference in clarity with all my speakers in my truck. The delay setup for driver listening is amazing, I’ve never heard music like that ever in my life! And I swear I am not getting anything out of this review as it sounds to good to be true… well I believe so!

- Reviewed in Canada on September 10, 2024Verified PurchaseI used this is a home audio setup with a clean 12V source and it is perfect for what I wanted. I have crossed over, tweeters, mids, mid-bass, and subs at levels and contours that are now almost seamless. Channel separation and imaging now are spot on.

- Reviewed in Canada on August 16, 2023Verified PurchaseThis PRV DSP compared to others I’ve used for example the Taramps is by far the more clearer sounding audio quality. Had it in for about a week or so before the DSP stopped turning on. Put my old taramps back in for the time being which everything works so I know I need to return this PRV one.

Verified PurchaseSo I've been on the fence about one of these for a little while now. I wanted to do something with my system, but not anymore equipment upgrades. So I decided to make this purchase. I didn't want to spend six or $700 on a helix so I went with this. It doesn't have all the bells and whistles, but perfect for what I was looking for. At first I wasn't a full believer. Just couldn't seem to get the sub to sound much better than it did before. Well, after some patience and some tweaking, you can believe I'm a full believer now! WOW! It seems to me, and I know this doesn't really make much sense, but it almost seems like this needs some breaking in. It just seems to sound better all the time. I'm doing everything by myself and by ear. I'm not investing in mics and all that other stuff, just not that important to me. Been playing around with the time alignment and oh my God it sounds incredible. Still obviously in the tuning mode but this is proving to be very well worth the money paid. I'm running one Alpine dual voice coil sub at 1 ohm and I cannot believe I'm getting this sound out of one 12" sub. Any problems I'll be back with an update. Oh, and also, no engine noise.
Update: 10 months later no probs. Upgraded some equipment and moved this to my glove box. Gets a bit warm in hot weather but no heat issues with unit. I just open the glove box for air circulation. I think I would like something better, but this works and I don't wanna spend so much time learning another one. It's $30 less than when I bought it so I highly recommend this if you're looking for something basic, effective, and affordable.

Verified PurchaseWorks great with the Mono-block amp setup that I am working on. Using the DSP to split the frequencies between tweet, mid, and woofer.
I have had no problems using this unit
