Hertz S8 DSP - 8 Channel Digital Processor with Hi-Res Audio (96kHz/24bit), 6 Analog Inputs, SPDIF Coaxial Input, Bluetooth 5.0 Configuration, Compact Design for Vehicles, Motorcycles and Boats

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.

Aún no lo instalo, pero la marca dice calidad . Así que espero no tardar en instalarlo

Pésimo soporte en México , no conecta después de la actualización no lo recomiendo

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.

Easy to use and Easy to connect. In fact i can connect to my IPAD, MAC Book and Iphone 15. Works flawlessly. Easy setup and you will learn it quickly.
