The DSR1 processor uses the PerfectTune app that gives access to low, high, and bandpass crossovers for each of the pairs of channels with up to 48dB in low and high pass mode and 24dB in bandpass mode. The signal delay feature makes up for the driver’s proximity to the left-side speakers and allows dialing up to 10ms of delay.
The 3Sixty equalizer and crossover make the car audio system clean and free of distortion by sending the right signals to the speakers. This signal processor leverages the features of 3Sixty and allows using an app to tune from mobile devices.
An amazing feature of DSR1 is that you don’t have to use it on a factory system but can also be used as a standalone unit. If your car has an aftermarket stereo running some aftermarket amplifiers, you can easily place this processor between them to get a fully digital audio system. You can do this by connecting the RCA output of the head unit into the DSR1 RCA inputs and also use eight outputs from the DSR1 to connect your amplifiers.
