Rockford Fosgate DSR1 Digital Signal Router w/ 3SIXTY Tuning

Overview: The Rockford Fosgate DSR1 is an interactive signal processor designed to allow you install an aftermarket amplifier and still keep the factory radio along with all its controls and features.

Configuration Menu: The initial module flashing is where the DSR1 will get configured for either Vehicle Specific or Universal modes.

• Universal Mode: In Universal mode the processor does not compensate for any factory EQ curves, only in Vehicle Specific mode, and there's no input signal summing with the DSR1. Six pairs of RCA input plugs along with a coax digital (S/PDIF) are provided on the Input Harness.
  • Aftermarket Headunit: If installing the DSR1 with an aftermarket headunit, the RCA connectors will get attached directly to the radio's pre-outs.
  • Non-Amplified (T-Harness): For installations into factory non-amplified vehicles, T-harnesses are available for select model vehicles, making installation much faster and easier. 
  • Non-Amplified (Hardwire): If installing the DSR1along with a factory radio without a vehicle specific harness, or an aftermarket radio with no pre-outs, speaker wire to RCA adapters
• Vehicle Specific: In Vehicle Specific mode, using a T-harness, the processor will read the factory data signals allowing use of the factory radio's controls such as volume, balance, and fade. In either mode, the DSR1's 4 input channels (front/rear) are combined to provide the subwoofer output signal. After the initial flashing is complete, Rockford's PerfectTune app will then be used for the setup and configuration of the DSR1. 
• Preferences: The Preferences menu allows you to assign the two Home-screen "sliders" (Default is Sub Level and Punch EQ), as well as options for Auto Close and Crossover Plot Overlay with the choices being On or Off.
• Device Setup: This screen allows you to quickly view the main settings after running the Setup Wizard. This will display the Device Mode (Stand-alone or Vehicle Specific), overall System Gain, PLC knob function if used, and the Input/Output configuration.
• Setup Wizard: This menu is used for initial configuration of both the Main inputs as well as the Aux input.
  • Device Mode: This determines how the DSR1 will be used, either Stand alone or Maestro T-harness (Vehicle Specific).
  • Input Source: This setting determines the type of input signal: Low Level (RCA), High Level (Speaker), and S/PDIF (Digital).
  • Input Level Switch Position: After selecting either RCA or Speaker level, this option is a reminder to move the physical switch on the DSR1 to either High Level or Low Level.
  • Headunit Sensitivity: This sets the input sensitivity range based off of the headunit's pre-out voltage. Choices are from 0.5 Vrms to 4+ Vrms.
  • Input Channel Configuration: Determines what input types will be connected. Choices are: Fronts (2-ch), Fronts + Rears (4-ch), and Fronts + Sub (4-ch). A convenient pictogram shows which plugs on the DSR1 will be used.
  • PLC2: The DSR1 includes an RJ-45 jack for the optional PLC2 Remote Level Control. This is a rotary control that can be mounted under the dash for quick, on-the-fly adjustment of one of three options: Subwoofer Level, Punch Bass, or Master Level. 
• Tune: This setting will give 2 options: Basic Tuning, and Advanced Tuning.
  • Basic Tuning: This is a 7 Band equalizer that affects the entire output of the DSR1 signal. The Bands can range from 63 Hz to 15.9 kHz with Q factor and Gain settings for each. The Gain can vary each Band's level from + 6 dB to - 17 dB.
  • Advance Tuning: This option allows more detailed settings to be edited for each of the 4 sets of output channels (Front, Spare, Rear, and Subwoofer).
    • Trim Level: Dual level controls allow volume offset for each of the 4 sets of outputs. Left and Right channels for each can be varied independently or can be linked together. Each speaker can be muted from this page as well.
    • Time Alignment: Each output channel can individually be delayed from 0 - 10 msec. Delay can be set in either milliseconds, inches, or centimeters and also include a phase-reversal option for each channel.
    • Crossover: All 4 pairs of outputs can be filtered if needed. Crossover options include:
      • Filter Type: All-pass, Band-pass, Low-pass, and High-pass
      • Filter Slope: This determines how steep the cutoff slope will be. Choices are: 6, 12, 18, 24, 30, 36, 42, and 48 dB/octave slopes.
      • Frequency: This allows you to pick the frequency of the cutoff point. The Band-pass setting gives 2 frequency options; High-pass and Low-pass. A wide range of frequencies are provided and will vary depending on the Filter Type selected.
    • Equalizer: The Advanced Tuning EQ offers up to 31 bands of equalization for each of the 4 sets of outputs.
      • Band: Selects which frequency band will be adjusted. Range is 20 Hz to 20 kHz.
      • Q: Determines how many frequencies around the cutoff point will be affected by the boost or attenuation. Range is from 0.1 to 10.0.
      • Gain: This controls the amount of boost or attenuation at the Cutoff point. Range is from -24.0 dB to +6.0 dB divided into 0.5 dB increments.
• Preset Management: The DSR1 allows you to save all of the settings as a Preset in one of 4 memory locations, which can be saved and retrieved via the PerfectTune app.
• Bluetooth: Pairing of a Bluetooth enabled device for setup and configuration is done with this setting.

Module: All of the inputs and outputs of the DSR1 are as follows:

• Input Side:
  • 18-pin input harness: Includes Front, Rear, and Aux In RCA connectors, S/PDIF coax digital input, and 18 AWG wires for power, ground, remote in and remote out.
  • Vehicle: This socket is where one of the vehicle specific T-harnesses will plug into.
  • Exp: A 4-pin Expansion port for future use.
  • USB: The micro-B USB port is used for firmware updates and configuration of the DSR1.
  • Status LED: Shows the status of the module: White = OK, Blue = Busy, and Red = Error.
  • Input Level: This is a 2-way switch used to change the input sensitivity range. Choices are High (= / > 4.1 V RMS) and Low (= / < 4 V input).
• Output Side:
  • 16-pin output harness: This all RCA harness includes outputs for: L/R Front, L/R Rear, L/R Spare (input taken from front channels), and L/R Sub outputs.
  • PLC: This port is an RJ-45 socket for the optional Rockford Fosgate PLC2 remote Level Controller.
