The ultra-compact S8 DSP (Order Code S8DSP) is the perfect solution for integrating any OEM source into your audio upgrade project for cars, motorcycles, and boats! S8 DSP is a distilled essence of technology at the service of the highest audio quality in a corrosion-free case cast in metal and composite materials. S8 DSP processes the audio signal with 96 kHz / 24-bit resolution and has obtained the Hi-Res certification from the JAS (Japan Audio Society), an acknowledgment that certifies the extreme level of audio performance achieved. The powerful 32-bit DSP manages 6 high/low-level analog input channels, one digital coaxial input, and 8 output channels, offering maximum freedom of configuration to the specialist. The SPDIF coaxial input is ideal for digital connection with a Hi-Res player, a solution that allows for maximum listening quality. For each of the eight output channels we have a level control, the 15-pole parametric equalizer, time delays, and crossover filter available. The 7-band parametric equalizer of the input signal allows obtaining a flat response from OEM sources, which often have an exaggerated emphasis on the low frequency.
Features:
Small and weatherproof, perfect for motorcycles
Compact size featuring all connections on one side to be installed anywhere
Anti-corrosion-treated PCB to ensure years of listening pleasure in open nature
Three different application setups: car, motorcycle, free placement (boat, van, pick-up)
Party and ride presets, to optimize the sound performance in all conditions
Configurable with a PC, a Mac, an Android device, or an iOS device
IOS/Android control APPs (Bluetooth 5.0)
• DRC control over app from iOS/Android devices
Powerful DSP with the excellent sound quality you expect from Hertz
Hi-Res audio (96 kHz/24-bit native resolution) for unparalleled audio quality
6-channel SPEAKER IN (2.5 - 21V rms) on a dedicated socket with a built-in USS (universal speakers simulator)
SPDIF coaxial input (up to 24bit/96KHz)
8-channel / 4Vrms-capable RCA outputs
Signal Output Active Limiter prevents clipping
Easy to use and connect.
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.

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.

Excellent !
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.

DSP S8
This is my 1st DSP and this is way harder than I expected. I fixed everything and sounded amazing. I'm not sure how but the file got corrupted so I had to start over again.... sadly I can't get it to sound as good as before. Part of the problem is the phone/pc software interface. You would assume that if the DSP file is sent from iPhone or pc both would be the same. However the phone app can read the file created by the pc but not the other way around. Can you get great sound from this DSP YES. But I regret not spending more money and go with a better brand so I wouldn't have to deal with this.

Lacking features
I dont have any quarrels with what it does do because what it does do works fine. However there are a few things I do not like. if you want to do any kind of phase adjustments with allpass filters you will not be able to do it with this DSP. The only adjustment you have for this is a 180 inversion in polarity thats it. This was the final deal breaker for me and Im forced to sell the unit and just get a Helix. Also the 7 band input eq sounds great but in reality you will only actually be able to use a few and heres why. Each band of input EQ has a fixed range of frequencies (1st band 20-76hz 2nd 45-189 3rd 113-473 4th 280-1170 5th 700-2940 6th 2000-8400 7th 6250-20000. Meaning if you have two adjustments to do in one area you will not be able to do it. There will also be bands that go unused because it may be in an area that doesnt need any input eq. It also does not have an input RTA like the helix. You will need to plug the unit into an interface and into REW to take an input RTA or have a standalone RTA unit. 15 bands of output eq is usable but not optimal For perimetric EQ precision is somewhat limited. You can have up to 0.1 precision for Q and gain and only 1.0 precision for hz. Like I said some of these are workable and what it does do it does well but having already limited bands of EQ and then being able to do no phase work was just a deal breaker for me. I wish Hertz would put out a higher end DSP to compete with the Helix I really do like Hertz products. This being the best DSP they have to offer is just simply unfortunate. If youre not doing super advanced tuning its probably fine
