Dayton Audio DSP-408 4 Input 8 Output DSP Digital Signal Processor with Built in EQ Crossovers, Time Alignment, and in-Put/Output Mixing for Home and car Audio

Needed to boost up the low end of my car subwoofer. Without it my sub just made the bass louder and a little less defined, with it i can set a very low crossover for my sub, lower than my amplifier or head unit allowed for, and eq boost at 23hz. System has the depth and balance i want now. Will probably add a 4 channel amplifier and really dial in the sound of the rest of the system later. The matrix signal mixing system could be confusing, but it's legit. Lots of flexible possibilities! One thought I had for a car setup you could create from just left and right input; you could create active 3-way front left and right speakers using 6 of the output, down-mix to mono for a single channel rear-fill, and down-mix a sub-woofer channel as well! Awesome! Another great feature, the DSP-408 let's you group output channels so you can apply equalization and filters in unison, a feature i wish Mini-DSP had! Very happy with the unit. Pros: Cool signal mixing system! 6 band parametric equalization per output channel. 6db/12db/18db/24db selectable high-pass and low-pass filters for each channel. Strong 3.5 volt RMS Output. Smart phone configuration with Bluetooth accessory. Good build quality (some sharpish edges on aluminum engraved logo) No turn off noise or POP! Low Price! Cons: Some slight turn-on noise. (very low) Some sharpish edges on aluminum engraved logo.

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.

Excellent item makes my music crystal clear

4 stars because alternator whine. That said, this is not designed for automotive use using the RCA inputs. The RCA inputs are unbalanced and will not work with a preamp. My solution was to use a preamp that has 4v balanced outputs and feed that into the high level inputs and turn the gain up a bit. Worked flawlessly to get rid of the alternator whine and hiss when the engine was off. Once the noise floor issues were solved in my mobile environment, tuning was next. Pro tip - the bluetooth adapter is great for getting audio into the unit, but the app is f*** trash. You need a laptop to program this thing. Once you get the software running on a PC and plug in, its very simple to tune. Took 5 minutes to get this thing sounding perfect with my computer, and 10+ hours trying to get it to work with my phone. Just use a PC. Once set up correctly, it brought my system to life. Concert quality audio, not even kidding. The before and after is incredible - when I disable everything and make it sound original, it sounds like you have water in your ears (my radio sucks) but once tuned, nice and crisp. The crossovers for the low end actually work - and well for that matter. Bass was muddy using the built in crossover in my amp. Got this thing set up and just wow. I didn't know my subs could hit that low, or high. Woke my system up.

I've heard that a few people have had unwanted noise issues with this unit. Personally I've had no noise problems at all. That said I put a ferrite choke on the ground approximately 3" from the dsp and I'm using audioquest tower rca's 2'. So far I'm very impressed with this dsp! The software for windows is a breeze to set up. Atm I'm using it with Focal access 2way passive and in the near future will be running 3way active again with the Focal 165AS 3.

Ik gebruik deze DSP voor een 3 weg aktief open baffle luidsprekersysteem voor in huis. Het configureren is erg simpel als je al wat thuis bent in het werken met filters. Het ruisprobleem waar ik hier en daar iets over lees valt in de praktijk erg mee. Ik heb 3 x de fosi ZA3 waarvan ik de volumeknop iets terugdraai om de ruis uit de DSP te verminderen, en heb er nu geen last meer van.Het valt op als je luidsprekers een hoog rendement hebben.Verder wil ik wel waarschuwen omdat Amazon,de verkeerde adapter voor de europese markt erbij doet, de ingangsspanning van 240V is prima maar het is de amerikaanse uitvoering dus die met platte kontakten !!!!! Ik heb daar melding over gemaakt,maar dat wordt niet begrepen. Ik heb alles teruggestuurd en kreeg 2 dagen later een andere DSP met…..weer dezelfde verkeerde adapter.Gelukkig had ik zelf nog een adapter liggen van 12V. De bijgeleverde adapter is 12V 1,5 A.Omdat ik graag de bijgeleverde adapter wil gebruiken,heb ik nu een US naar EU adapter besteld. Voor de DSP geef ik 5 sterren, zeker gezien de prijs, dit ook voor de service van Amazon,maar helaas heeft het niets geholpen !!! Ik heb mijn best gedaan door een mailje te sturen van het probleem. Veel succes als je hem ook besteld,bekijk eerst de adapter, het terugsturen is zinloos !!! Koop de US-EU omzetter……

Alles bestens

Se tiene que tener detalles y ajustarlo muy bien apoyandote en un RTA en mi caso lo use a 4 vias y acopla muy bien el sistema no lo use con control ni bluetooth solo a la pc en ocaciones se desconectaba pero si se almacenaron los presets

最初RCAにしててブチブチ切れる現象発生。音量が下がると再起動がかかるっぽい。REMにして解決。 チャンデパが超手軽に楽しめる。設定は複雑怪奇多種多様w こんなの素人が簡単に弄れる世界ではなさそう。chat GPT先生に教えを乞いながら使用中。環境が劇的に変わります。 入力と出力が多いのは思いつきを実現出来る余裕があるので重宝してます。
