Rockford Fosgate DSR1 8-Channel Interactive Signal Processor w/Integrated iDatalink Maestro Module

This unit offers lots of customizations based on your vehicle. Allows for total sound adjustments between all speakers as well as adds the Punch EQ boost to the menu. App allows you to configure it via bluetooth with phone but works best on a table as a bigger screen to see everything on. The App also allows for all of the gain adjustments . Very ease to use and configure. The directions were a bit lack luster but there were many videos out there that show you how to do everything with it.

I installed this on my 2014 Ford Explorer Limited with the Premium Sony sound system. This was used to replace the Sony amplifier, and send signal to my aftermarket JBL DSP4086 amplifier. I left the dsp flat on the DSR1 and did all the tuning on the JBL Amp. Haven't had any issues so far, and the Perfect tune app seems to work just fine when I need it. I also use the remaining two channels of output to send signal to my aftermarket subwoofers. All in all, a huge upgrade to the sound of this Explorer, and I could not be happier. Cheers!

Installation was a breeze. The unit requires three updates/programming. If you follow the steps in the order given in the instructions, it works great. Miss one step and you'll have problems. But easy to remedy by going back and follow the steps. The DSR1 has outputs for 8 channels. 4 are standard stereo outputs, one that is labeled "spare" channel and then the subwoofer outputs. I chose to use the iDataLink Maestro cable and features which allows for retaining all the factory controls. The systems, once tuned and amps set with proper gain sounds AMAZING! The Perfect Tunes software for the EQ and Crossovers is a bit overwhelming to learn to use. This is not a standard EQ, but a 31 channel EQ. There is a setting for a standard 6 bar EQ, but since I chose the Maestro features I can't access that in Perfect Tunes as it relies on the factory head unit's EQ settings which in my case is a 3 bar EQ...Bass, Mid and Treble. So what I did is set my speakers up to crossover settings with highs going to dash, mids going to front doors and bass going to rear doors. This allows me to use the trim levels to control what you normally control with an EQ. Between that and the 3 bar EQ on the HU I get a lot of control. If I need more control I go into the 31 bar EQ. This setup is not user intuitive. It will require a bit of a learning curve unless you've worked in audio before. It is pretty high level audiophile stuff. Read up on Rockford Fosgate 3.sixty as it has basically the same settings as the Perfect Tunes app. Update:9/24/2020-while making some adjustments to crossovers today the DSR1 locked up. My volume control did not affect volume of music coming out of speakers, although the display showed the volume control change it had no effect on the actual music coming out of the speakers. I turned off the vehicle and let it sit for a few minutes and then turned vehicle back on. Now I have no sound coming out of my speakers. Everything looks fine on the display but no sound. Had to remove the radio console from the dash since I mounted the DSR1 behind the radio, then unplug the harness from the DSR1 to get it to power down. Plugged it back in and everything is working again. So warning to others...mount this unit somewhere you can get to easily so you don't have to tear into your dash every time it needs a reboot. Of course that requires the purchase of more cables to extend it to where you can mount it. I'm about to go shopping now for the cable extensions. Hopefully its plug and ply. I'm capable of making my own cable so I may go that route if I can't find a premed extension so I can relocate the DSR1.

For the price this has to be the most affordable quality DSP on the market. 4 channels of input and 8 channels of output was perfect for my needs. Independent volume, time alignment, crossover, and equalization for each individual channel it’s amazing. You can tailor each part of your system just the way you like. Adjustments are at your fingertips with the Perfect Tune app. I also have the PLC2 Wired level control which I assigned as a master volume. If you want to bring your sound system to life and have customization abilities a DSP is a must have and this is priced very well. Can’t go wrong with Rockford either. Once you get this don’t forget to update it. The update process is not the most user friendly but Five Star Car Stereo has excellent YouTube tutorials about this DSP and a dedicated YouTube video for the update process.

Great entry level dsp. You get a ton of features (31 band eq per speaker, time alignment, crossovers, ect.) for the cost. The initial setup was a bit of a headache, but the sound quality is excellent. The app is trash on Android devices but works fine on IOS.

I've had issues with this product for a while. For no reason, my sub would stop playing, so I would have to run the setup on the Perfect Tune app to get it working again. I did this probably 10 times since I installed it. The latest time, I tried to get it working the same way, but this time, the whole thing stopped working. I tried several times to run the setup, but no sound came from any of my speakers. Then, the Bluetooth connection stopped working. I had to rip apart my dash to remove the unit so I can try and re-flash it and see if that would fix the problem. No-go. Bottom line, I am completely dissatisfied with this, and it has caused me a lot of stress and extra work. Here's the kicker; they refused to honor the warranty because I bought it from Amazon and not an authorized dealer. $300+ down the drain.

Installé par nécessité pour bypasser l'ampli d'origine et après des heures de réglages mon verdict est le suivant: Bluetooth à chi... pour faire les réglages bah faut être a dix centimètres max sinon bah tu y arrives pas, boitier en plastique médiocre, et qualité audio du DSP comparée a un alpine PXA H800 bah c est du pipi de nouveau né...

Ein sehr gutes DSP. Man muss aber wissen, dass es mit dem Einbau eines DSPs nicht getan ist, denn dahinter benötigt es noch eine Endstufe. Das hatte ich selbst beim Studieren der heruntergeladenen Anleitung vor dem Kauf nicht erkannt, weil die Endstufen nur winzig klein angeschrieben waren. Ich dachte, dass das Stecker wären... Grundsätzlich bietet einem dieses DSP fast alles, was man sich als Soundfanatiker wünscht. Einzig eine Dynamikbassmöglichkeit fehlt. Aber es geht natürlich auch ohne, denn man kann mit dem 7 Band „Grund“-Equalizer nachträglich allgemein immer etwas nachregeln und wer möchte, kann diese Einstellungen dann als Presets speichern und bei Bedarf abrufen. Zusätzlich steht einem für jeden Lautsprecher getrennt ein 32 Band Equalizer zur Verfügung, mit dem man so gut, wie jede Frequenz hinein, und herausregeln kann. Besser geht es kaum noch. Aber auch die allgemeine Lautstärke, Bassboost, die Lautstärke die einzelnen Lautsprecher zueinander, der Zeitversatz jedes einzelnen Lautsprechers lassen sich mit der App auf Android aber auch Apple komfortabel regeln. Einziges Manko ist, dass die Reichweite des Bluetooth meiner Erfahrung nach nur ungefähr 30cm beträgt, was heisst, dass man das DSP zwingend in nächster Nähe des Fahrers unterbringen sollte. Bei meinem Skoda Octavia RS, der in der Mitte nur noch das flache Columbus Display mit viel Platz dahinter verbaut hat, konnte das DSP direkt dahinter eingebaut werden, so dass ich grundsätzlich auf dem Fahrersitz sehr guten Empfang habe, wenn ich das iPhone direkt vor das Radio halte.

Perfetto in tutto, una bomba!!!
