    • Sounds great!
I took care to avoid ground loops in my car audio installation. I used this with a Dayton DAC and some attenuators for physical volume knobs for USB audio input with a tablet. The Bluetooth streaming also sounds good. My biggest complaint is it takes WAY too long to switch presets (via Bluetooth from Android app) and cuts audio while it does it. The good news is, with 8 channel tuning with an added main and sub volume knob, I hardly ever want to change it from my main setting. For the price point I am plenty satisfied. I will update my review if my opinion changes ... show more

    • Game changer on hard to tune systems
Despite using high end components, my car stereo had some dead spots in it where it just sounded flat. I tried several different approaches and then is dawned on me- I used a DSP for my other systems at home (dbx driverack) and they solve problems, so I ripped out my AudioControl components and started over with the Dayton DSP The windows app is fine- it’s simple and makes sense. I honestly can’t believe people complain about not having a flashy app with skins etc- it’s just a tool for setting up your rig. Thank you for NOT making some silly bling app. The capabilities are exceptional and everything works exactly as expected. The sound is clean and clear, and it can do everything I need. Now, thanks so a calibrated microphone and an RTA app... it’s finally a good sounding system. If they wanted to take it a step up, I’d appreciate a sub harmonic synth or a BBE type processing ability or license AudioControl’s much sought after ESP2 and build in the capability. I’d put one in all my cars if they added those features. All in all,I absolutely love this DSP- it’s finally made car audio SO much easier. Anyone can now have a killer system if they take the time to set up properly. My system: Chevy MyLink head unit, Dayton DSP, Alpine Amos for sub and fronts, stock Boston Acoustics amp for rear speakers. All Polk MM components & Polk MM 10” sub. AudioControl ESP2 and Epicenter. ... show more

    • So disappointed. ☹️
I purchased this this unit to replace a different brand DSP that was introducing unwanted distortion. I had read reviews on this unit and saw many mentions of background hiss or a hum typically caused by a ground loop (poor grounding). I thought maybe these people hadn't taken the proper steps to ensure they had a properly grounded system or they were using cheap RCA cables. I connected the unit in place of my previous DSP which was a cheap unit but had no noise issues. The sound quality while my vehicle was off was excellent and I had no background hiss or noise. I messed with some settings via the PC program and its very easy to use. Unfortunately this was short lived after starting my vehicle. There was a constant low frequency hum and a high pitched whine that increased in frequency when my engine RPM increased. I decided to try some troubleshooting to verify there was no issues with my install. I decided to run a temporary ground and power line directly to the battery just to see if it would help. It did not. Even though I know my connections are very good I decided to go through all of my entire system and verify everything was still secure. (I really wanted this DSP to work) I found no issues with my system connections. I read in one review that someone "resolved" the issue by removing the REMOTE IN connection and having the unit turn on via the RCA signal. Again, no change. I even ran a temporary set of RCA cables with no change at all. When I removed the unit from the signal chain completely there is absolutely no noise at all. I'm fairly certain the issue is not on my end. My system consists of a Pioneer Head unit, Rockford Fosgate amplifiers, Knukonceptz Krystal RCA cables, and Knukonceptz 0 gauge OFC power from the battery to both amplifiers and the alternator and dual 0 gauge grounds on my battery with brand new battery terminals and a new battery. All ground connections have all paint removed and are connected with a gold plated terminal blocks and I apply an electrolytic compound between the terminal block and vehicle that improves and protects the connection. I understand a device maybe being limited in options because it has a lower price point. However I can't understand how a device could be sold with this kind of issue and it hasn't been addressed with an improved design. I would be more than happy to pay an additional $50 if this was resolved in a redesign as it would still come in much cheaper than most other DSP's. PROS: Easy to install, easy to setup and control, great sound quality. CONS: Overpowering hum and whining noise while vehicle is running unfortunately makes this unit unusable for car audio. 😞 ... show more

    • Music to my ears
I wanted a stealthy system but the AudioControl DQ-61 eq that I had previously is controlled by knobs so I Installed it in the glovebox compartment. I didn’t like this setup. I replaced it with the Dayton dsp-408 because it is small enough to be hidden away under the dash and it has bluetooth and it’s cheap. The other dsp with bluetooth easily cost double. I used to have the factory deck > AudioControl DQ-61 goes straight to the > amp. Now I have deck > AudioControl Lc2i > DSP-408 > amp which costs about the same but sounds much better. However, most of the time I use a LG V20 phone with quad DAC connecting straight to the dsp, completely bypassed the deck and the lc2i. This method sounds best. I only use the deck/lc2i for phone calls or when I don’t have the v20. By the way, don’t use the dsp-408’s speaker wire input (doesn’t sound good), use a quality active loc like the lc2i instead. Controlling my dsp unit via app is much better than via knobs. It’s much more precise which resulted in clear separation between speakers, sounds, frequencies. My 10 inch sub never sounded better before. I clearly have a sound stage now and I can position it precisely. I really enjoy music in my car now. I agree with others that the phone software is kinda weird but once you understood it becomes non issue. I liked it so much I actually got a second unit to replace in my other car. Both systems sounded a few times better and I am happy not having to spend a fortune but able to achieve decent sound, style, convenience. I recommend you trying out this unit before spending more $ upgrading your speakers, sub, amp, etc. you’ll be surprise how good your already existing system can sound. Just make sure you run 100% oxygen free cooper wire throughout and solder whenever you can instead of crimping. That’s it nothing fancy and you can thank me later. ... show more
