Car Audio DSP 2.4X Digital Crossover and Equalizer 4 Channel Full Digital Signal Audio Processor DSP with Sequencer Remote Relay

The low cost attracted me, but the flexibility and sound quality justified the 5 star rating. Its loaded with useful features, and the crossover is excellent. I hooked it to a 13.8 VDC regulated linear power supply, and use it to control my woofers and subwoofer in a bi-amped tube/solid state 2.1 home audio setup. It works surprisingly well in that role. The longer I've used it, the more impressed I am. It really allows you to dial in some fine detail to your room and tastes. I was able to set and increase the crossover slopes, adjust the gain levels, setup delay to the woofers, and cut room nodes dramatically using the PEQ feature. Addressing the room nodes made a significant improvement. There's no question that this is an improvement over what just an active crossover can do....it's a bit mind boggling.I didn't find it overly intuitive to use at first, but managed to make it do what I wanted. It's making more sense as I get used to it. Great unit at this price, but I could see some benefit from having a laptop or phone control to make adjustments from the listening position....I'm guessing that feature won't be found in this price range. Definitely recommended.

Very well built. Great sound quality.

Works great had for over a year now no problems and easy tuning and saving presets

This is a great product. Connectivity so far is great and is user friendly. A few of my old school buddies were trying to convince me that it’s too complicated to tune. But if you know your specs mid, highs, bass it’s easy to program and more precise than any crossover. Well they heard it for the first time so now I have about 8 systems to tune in Spring😂😂. ( I already have processors on my Sound system and they are the same). Hook straight in your amps and tune.If you have a small set up this is all you need. No eq needed, no cross over.

Awesome product add the extra level of tuning to your system to get really great clarity even out of beginner pro audio equipment. definitely going to get more in thr future

Works pretty well, easy to navigate the menus and seems like decent quality, good eq band and crossover settings, but after a couple months of use it will randomly put all of my outputs into limiter and nothing plays except for a very noticeable high pitched static sound, just randomly started doing this, does it like once or twice a week

Performs exactly as expected, arrived quick, and was priced very well. I’ve never once had an issue with a single PRV product, love it and will recommend. Running a 2.8 for the mids and highs and a 2.4 for the bass, having exactly ZERO of the finicky issues you see people having with “upper tier” dsps.

Works great! It does so much that you won’t keep up with all the prompts. Made my music a lot better!!

Working well! Using this for speaker setups at parties/small events to do crossovers between subs, mids, and top speakers. Have also done delay towers with this, and is a nice solution all around. Has "graphic" EQ (no actual graphics), delay, gain, crossover, and phase controls. Would be nice to have a pan feature though.

Sound quality improved nicely although i wish i bought the 8ch

Llego antes de lo esperado 10/10 tiene buen sonido

発注から少し時間（11日間）はかかりましたが、問題なく納入されました。本来、車載用の機材ですが、ホームオーディオ用に手持ちの12V電源でノイズ等の問題もなく動作しています。これまでスーパーウーファー用パワーアンプのローパスフィルターとしてRCを使用していて調整が難しかったのですが、本機を導入することで駄耳の私でも納得できる結果が得られました。（35Hz以下、BT-36dB/octで使用）価格の点でも、他の同様のデジタルフィルターよりも安価で満足です。

Works great. Easy to use. Very easy set up.
