Features

Bringing innovation and technology to the Automotive Sound market, PRV Audio launches the DSP2.8X Digital Signal Processor, capable of making various adjustments, from 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.

    Q With this DSP do I need to run an equalizer?
    Asked by Ralph Miranda on April 16, 2020 4:47 am
    A

    The DSP 2.8X has a built in equalizer with presets. You can use an external equalizer if you wish. You can use up to 2 with this DSP.

    Q I forgot my password
    Asked by Jose on April 11, 2020 8:46 pm
    A

    If you forgot the security password you will have to factory reset the unit. You can do this by holding the first 3 output buttons with the unit OFF and then turn it on while holding the buttons. This will give you a prompt to reset the DSP.

    Q How can I connect 3 amps with 3 equalizer using this DSP?
    Asked by Tony on March 29, 2020 10:44 pm
    A

    With this DSP you will only be able to connect 2 equalizers as it only has 2 inputs. If you would like 3 or 4 equalizers you would need 2 of the DSP 2.8x.

    The DSP 2.8X has a crossover built in along with many other features. With this you do not need to use another crossover.

    Amazing product

    The quality of the sound it’s a lot better you need to know a lot of sounds frequency and all that stuff if you don’t it’s a little hard to equalize it but it half a lot a few EC set ups you make it sound really really good

  3. Mark D.

    Well worth the money spent!

    I really like this product. Was looking for an eq and in the end I’m glad I got this. It’s got way more than any equalizer at this price point not to mention time delay. My only complaint is that all the channels are controlled as a whole with it’s left or right counterpart so individual speaker control is not an option so I may end up just getting two of these and splitting up my channels left and right so I can individually control each speakers delay.

    I upgraded my stock 6.5 with PRV 6.5 – 6MR500CF-NDY-4, for the batwing fairing, added PRV 6×9’s – 69MR500-PHP-4 in my saddlebags, and PRV Super Tweeters – TW450Ti-Nd-4, in front mirror holes. Also running 2 amps, one for the 6.5’s and one for the 6×9’s. The PRV DSP 2.8X is AWESOME!!!! I’m running both amps off the DSP, and the DSP is a much needed tool if adding one amplifier or many amplifiers.
    I HIGHLY RECOMMEND THE PRV DSP 2.8X!!!

  5. Modesto

    The DSP is AWESOME, and Tim the tech is extraordinarily helpful.

  6. Larry Choate

    Purchased the dsp about a month ago, haven’t quite got the grasp on all the functions, but have noticed the difference in sound quality with minor adjustments with it. It performs as expected and more. Worth the money and definitely made my system better…
