Hertz SPL Show S8 DSP Compact Digital Interface Processor 6 in + Digital in & 8 outputs

This has a lot of wires to connect. So, I recommend making your own harness to make things neat. but not necessary.The setup was tedious, but once I figured it out, it works with no problems.The sound is excellent. It seems to have cleared up the signal from my OEM head unit (2022 WRX). It's easy to use the EQ, etc. It's very accurate with the adjustments. The time alignment is a little finicky, but works very well.One of the best things about this DSP is that it flattens the OEM head unit signal and can sum front and rear to get a full range signal, if that's something you need to do. From there, you can EQ what you need to/want to. It drastically improved the mids. Just an amplifier doesn't cut it. You need something like this to increase specific Hz.Size: This is very small, esp. for it's capabilities. I fit it up behind my glove box no problem at all. No noise induction from the HVAC blower motor either. It uses differential inputs, and the sound is crystal clear.It's very classy looking too, esp. compared to so many other DSPs I've checked. Also, other ones like JL are way too big and clunky. For the price, I highly doubt you will find a better DSP.

I have (had) a really nice stereo set up. I don't have a dsp so thought that would be one last piece I could add to properly tune it. I spent all day putting this in line. It is 1000% properly connected. It turns on and lights show it is working correctly. BUT..... I can't connect via usb or bluetooth. I have tried on 3 different Apple devices. I even went today and bought a cheap Windows laptop thinking that would crack the code. Nothing. Now all it does is block the signal to my amps so my system puts out zero sound. I very much regret the purchase. Now I have to wait for God knows how long to get tech support from Hertz. If I don't hear from them tomorrow, I will probably just take it apart and get my money back. Will take me another few hours to rewire by system again. Major waste of time. Zero stars.Update:I bought a second unit. It connected via BT and USB. It works fairly well... However there are still glitches with the software (It's reversing ch. 3 and 4 in the software even though the inputs and outputs have the correct information) I am trying to get worked out with support and there are features lacking that should be available at this price point (being able to see all channel's eq curves at once). All in all it sounds good and is working well. Tech support is one person and he's impossible to get a hold of. The main draw for me to this unit is it's size. If not for that I would be sending it back and getting a JL Audio DSP. Hopefully I can get the remaining bugs fixed. I would give 1 star for quality control, 3 stars because it does sound good and it's nice it connects to ios as well as a PC. But it's a bit buggy. and 0 stars for impossible tech support.

Initially, I harbored doubts about its practicality. However, upon its installation and subsequent utilization for my audio system, I was astounded by the transformative impact it brought about.

All I can say is this thing is amazing. Only thing preventing a 5 star review is the setup takes a long time and there is a lot of trial and error. The app has a lot of learning curves to it like saving the presets and finalizing to the unit. Wish there was a better way to quickly save settings or it auto saved changes made.Now the good part. This is a bad ass piece! I had tried a much cheaper DSP unit and first one failed after only a week. The second lasted a little over a month and luckily was able to return it. Decided to spend over double and get the Hertz. All I can say is don’t waste your time with cheaper ones. This unit has amazing sound quality with zero noise, and eliminated all distortion. The ability to link channels and adjust both sides of each set of speakers is so nice. Makes fine tuning a breeze. The crossovers and time alignment really made my system come alive. I really cannot believe how much better the system sounds now.The app and setup on the computer takes a long time to get it all set up but once you get it dialed in wow. Just be sure to save and finalize to unit before closing the app or shutting down system. My system has never sounded better. The bass is punchier, the mids are crystal clear and the highs are crisp and clean with no distortion. You will not regret this one. It’s worth it if you want superior control of your audio system.

I purchased the DSP for an audio build. It was a few months before I got everything to do the build. Got everything installed and the unit will not connect to a computer. Tried 4 different computers and multiple cables. Contacted Chris from Hertz, went through every step to resolve issues. Still nothing. Only to be told I cant return it through Amazon.Talked with Chris from Hrtz directly and he got it handled for me. So we shall see when the new unit arrives.

Cumple con las expectativass, buen sonido, y nivel de configuración. Para un sonido de calidad sin llegar a ser un equipo super costoso. Es para los entusiastas, si lo tuyo es ser super hiper detallista, deberás buscar un equipo mucho más costoso y con más prestaciones. Pero este dsp cumple con una excelente relación calidad precio

If your looking for the best DSP for a motorcycle look no further, this is the one right here!!

Had issues at first, figured out how to update it and that may of fixed the one. Still has issues connecting but it works eventually
