Rockford Fosgate DSR1 Review

So, the Rockford Fosgate DSR1 was developed in collaboration with iDatalink Maestro. It’s a digital signal processor that comes with a Maestro integration module that can be flashed with vehicle-specific firmware. This allows for seamless integration without losing any of the factory-equipped controls and features.

You can use it right out of the box with high or low-level input, or with a quick flash download. Once connected, you have complete control over the sound profile using the Rockford Fosgate PerfectTune™ software.

In this review, we take a closer look at the Rockford Fosgate DSR1 and discuss the features and offerings to help readers make a wiser decision. 

An eight-channel interactive signal processing unit, Rockford Fosgate DSR1 comes with all the features you would want to optimize the performance of your car’s audio system. It is actually two products in one. It combines a full-featured 3Sixty digital signal processor with the iDataLink Maestro amplifier integration module.

Features

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.

Advantages

Easy Upgrade 

As the car’s processor controls the audio system, it is important to integrate the upgrade with the digital network. The Rockford Fosgate DSR1 comes with an integration module and a fully-featured signal processor to let you add an amplifier without losing the factory controls.

With the unprocessed line-level signals the processor uses from the factory receiver, it is possible to tune the sound without having to tweak the factory settings. The factory radio keeps working like before and all the vehicle features are retained. 

iDatalink Maestro Integration

For newer models of Ford, Chrysler, Lexus, Jeep, Dodge, Subaru or Toyota, the integration of the iDatalink Maestro module allows controlling the outputs of the processor right from the factory radio.

It also allows replacing the factory amplifiers with high-power amps and speakers and use the processor to get seamless control over the entire system. The compact size means you can easily upgrade the systems on smaller cars and even the 2014 and newer models of Harley Davidson.

The iDatalink amplifier replacement module uses a vehicle-specific harness to supply a clean audio signal and digital control data to the processor. With a PC, you can download the firmware for your vehicle from the iDatalink website to the DSR1. Once you do this, it is capable of translating all the digital instructions of the car to give better control. 

Control Via Mobile Device

As the DSR1 uses the same technology that the 3Sixty signal processor uses, you can achieve excellent sound quality from the car’s sound system. You can connect to your Android or iOS device using Bluetooth and load the PerfectTune app to start controlling the audio system right from your mobile device. You can see the configuration, EQ controls and graphs and other details of the speakers right on the interface.

8-Channel Processing

The Rockford Fosgate DSR1 features eight output channels of signal for amplifiers to send to the speakers, subwoofers and tweeters. Each of these channels has its own polarity switch, level adjustment, crossover network, equalization and time alignment setting. This means you get nothing but a perfect sound.

Sound Quality

The DSR1 also provides a significant improvement in sound quality. The device is equipped with a 248MHz 32-bit digital signal processor that delivers a cleaner and more precise sound. The DSR1 can also correct any sound imbalances caused by the car’s acoustics, ensuring that you hear the music as it was meant to be heard.

The device can handle high-resolution audio files and is compatible with most audio formats. The DSR1 also has an impressive dynamic range, which allows for a more natural and detailed sound.
