Gunz That Turn on Nunz
Review of Head Unit:
Rockford fosgate DSR-1 DSP.
so me and CSCstang got to playing with this on his SQ mustang as a stand alone processor via low level rca inputs. Right off the bat, it had a horrible time trying to pair with his note 8 which has bluetooth 5.0 lol. We literally had to turn off the car, unplug the harness and restart the app on his phone for the bluetooth to connect. The bluetooth range is extremely short, even sitting in the driver's seat with the DSR1 in the bottom of the passenger seat, it would disconnect here and there if it starts acting up. However for the most part it worked well enough for me to do the tuning for a few hours. I can foresee a lot of frustration with the bluetooth connection in the future though while driving.
Its a 3 way active front plus subwoofer setup, his head unit is a pioneer 2800bs which has a 4 volt pre-out signal. All adjustments on the head unit is off and flat, I've put on basic crossovers points and slopes for all the drivers and we started testing with 40/40 on the head unit volume and also max on the phone volume. Gain settings are the same as before we put the dsr-1 in. On the config wizard we chose the 4 volt pre-out signal to match the head unit.
Off the start we noticed the output was weak in comparison and had to gain up to get proper levels. So to remedy this, we actually chose 2 volts on the config wizard and that made the dsr-1 output a much stronger cleaner signal. In the end we ended up choosing 1 volt pre-out input in the config wizard and got a very powerful signal which allowed us to lower gain on the amps.
Also when we were adjusting time alignment and output levels on the software, some how the right and left side got switched mid tune.... Utterly ridiculous. You cant get it back to normal without redoing the config wizard again. So i just lived with it and flipped the time alignment numbers. Stage is pretty dead center regardless of this roadblock.
I noticed the EQ cuts and attenuations make very small minor changes unless you really stack on the DB cuts, it goes by half db increments but i wish they just made it a full db increment because you barely notice anything with half increments.
Final thoughts
Audio performance signal and tuning wise = A
software stability/reliability = D+ for now
Software ease of use = B, for what it is.
I still actually like this software and interface waaay better than the ARC audio PS8 processer i got to play with on fly_marlin, another socal buddy has. I might snag one up for myself in the future.
All in all, its worth what it costs The achievable blend between mid, midbass, tweeter and sub with the crossover slopes and points alone already made it worth it even with all the bugs in the software which are actually workable. Hopefully they make software updates to fix all these bugs we experience.
Audio wise, the signal is very clean with no noise and powerful as well if you choose the right config wizard setting. No worries on the sub signal, its very strong and powerful so SPL guys would love this as well. For dsp beginners, it'll be a steep learning slope for people used to simpler dsps and head units. Lets just say you cant really wing it by ear as you would with the simpler dsp/head units. An RTA will definitely be helpful with the EQ work.
The whole setup sounds a lot better even though we didnt spend much time on the EQ portion. We will later if he gets an RTA. But seriously though, **** sounds pretty fking sweet already just from crossover work and relatively flat EQ.
@blazian87, ya'll might want to see my experience with it. @Jcsaudio did you experience some of these issues? How was your tuning experience like? This unit requires much more extensive tuning work than the TWK's advanced mode especially the parametric EQ portion, you really need to know what you are doing precisely
