Dsr1 Presets

[Earlie Schwoyer]

Lookingat its most basic elements, the Rockford Fosgate DSR1 is a four-input, eight-output digital signal processor. The inputs can switch between preamp signal voltages and speaker-level signals. In terms of maximum voltages, the preamp mode will accept up to 4 volts of signal, and the speaker inputs will accept 12.5 volts. When using the speaker level mode, remote turn-on detection circuitry can activate the DSR1 when that factory radio starts playing music. A stereo auxiliary input can also be used with a portable music player, game system, computer or Bluetooth interface such as the Rockford Fosgate RFBTRCA. The processor has a coaxial digital input that can be used in stand-alone mode or with a factory audio system.

There are two main circuit boards inside the DSR1. The large primary board includes the power supply, the main microcontroller and the DSP chip, along with the associated input and output circuitry. Large-value load resistors are integrated for configurations that use speaker-level inputs. Rockford Fosgate chose a high-quality all-in-one Cirrus Logic DSP that includes four analog-to-digital converters on the input side and eight digital-to-analog converters for the outputs. The processor features a 32-bit core, so processing math is handled quickly and efficiently. The system is controlled by an STMicroelectronics ARM Cortex-M0 32-bit, 48 MHz CPU.

The daughter board is from iDatalink and handles communication with the CAN bus in the car or truck. This board also includes the Bluetooth transceiver as well as its own STMicroelectronics microcontroller and a pair of Texas Instruments automotive-grade CAN transceivers to listen to the computers and source unit in the vehicle.

As expected, everything functioned flawlessly. The high-Q cut was short by about 0.5 dB from the target -10 dB, but this is normal. In terms of overall frequency response, the -3 dB point was at an extremely low frequency of 2.5 hertz on the bottom and 23.4 kHz on the top end. This performance is excellent if you are a basshead with a preference for infrasonics!

I also checked intermodulation distortion using the ITU-R standard of feeding the device 19- and 20-kHz tones at equal amplitudes, then checked the output for sidebands and a product at the 1-kHz spacing between the signals. The DSR1 performed exceptionally on this test, with the product at 1 kHz and the sidebands both being at more than 100 dB below the stimulus. If you want to assign that a percentage, it would be 0.00087%.

For those of us who frequently spend time calibrating audio systems, the layout of the configuration interface is crucial to our productivity. When your installer first connects to the DSR1, they can use the device setup wizard to configure the inputs, outputs and signal routing. As you can see from the screenshots from my iPhone, the wizard options are quite intuitive, and the system configuration options are adequate for almost any system design.

The Trim Level screen makes it easy to adjust the output of each speaker in the system so that their volume is balanced at the listening position. Channels can be adjusted in pairs or individually when you click the chain link button in the middle of the two sliders. The little speaker icons on each output can mute each channel so your installer can compare the left and right channels. Output levels can be adjusted in 0.5-dB steps from 0 to -30 dB.

The Crossover screen allows your installer to configure high-pass, low-pass or bandpass crossovers for any of the channels. Suppose the design of your subwoofer enclosure requires an infrasonic filter. In that case, your installer can implement a bandpass crossover on the subwoofer channel and set the high-pass frequency anywhere from 20 hertz and up. A graph helps to show the predicted response of the filter configuration.

You can also access different system configuration presets from the setup sub-menu. You could have a calibration created for critical listening with the engine off, another for normal driving conditions and a third for those times when you want to really crank the system.

Another cool feature of the DSR1 and its Bluetooth configuration connectivity is that Rockford Fosgate has created a PerfectTune app for the Apple Watch. When your iPhone is connected to the DSR1, you can use the smartwatch app to control the system volume, subwoofer and Punch Bass levels and select between the main and auxiliary sources. You can also mute the system from your watch. This is totally cool!

just my preset for Reshade for DS1-R I'm still working on it but good for playing as I'm currently doing my play through! I went in depth with the setting I've done other games but finally learned how to make presets to share!! Enjoy and I hope to see your summons! Jolly Cooperation!

PLEASE let me know if you have ideas on something to change
