Rockford Fosgate DSR1 - User Manual

This DSR1 Is Pre-programed for
You.
All DSR1s that we ship are programed for ‘14 through ‘18 Harley Infotainment radios that only have the front channels enabled. If
you have a ‘19 or newer Harley with a GTS radio you will need to download our DSR1 setup file for the GTS radio. If you do not
have a factory radio simply hit the EQ reset button in the EQ section of the DSR1 app to set the EQ to flat. Then make what
adjustments you need. Other radio configurations like Ultra, CVO, etc. with four or more speakers will need alterations to the EQ
curve that we have set for you. The tune that we put on the DSR1 is free of charge and not guaranteed to be exactly what you need
for your particular situation. User/installer adjustments are required when using a DSR1. You are responsible for all adjustments in
your new audio system. Read the extensive information here and the articles we have published on our website and get to know
what adjustments are needed for your system.
● We have already updated to the latest firmware so there is no need to connect to your computer.
● This DSR1 is already setup for a typical install on a ‘14 & up Harley Davidson with a factory radio with 2 channel input
(front only). Therefore you will not need to go through the setup menu in the Perfect Tune app. The only reason to go
through the setup menu is if your system is not a ‘14 & up with factory radio and/or you are feeding the DSR1 with more
than just the front channels
● Use the “Basic Tune” EQ in the DSR1 app unless you know what you are doing in the “Advanced Tune” section. You
can find several articles about using the advanced tune at
https://www.americanhardbag.com/pages/installation-guides .
● Understand how the “Remote In & Remote Out” connections should be made before you install your DSR1. Improper
connection of the remote in/out can void your warranty.

Overview

1. Usage Features
2. Maintenance Features

This document describes the Rockford Fosgate DSR1, a digital signal processor (DSP) primarily designed for use with Harley-Davidson motorcycles, though it can be adapted for other applications. The DSR1 is pre-programmed to simplify installation and optimize audio performance, especially when integrating aftermarket audio components with a factory radio.

The core function of the DSR1 is to process audio signals from a factory or aftermarket radio, correcting for inherent frequency response issues and providing clean, optimized signals to aftermarket amplifiers. It acts as a bridge, allowing users to upgrade their audio system without replacing the head unit, while still achieving high-fidelity sound. The DSR1 is particularly useful for Harley-Davidson bikes from 2014 onwards, addressing specific audio characteristics of their infotainment systems.

Usage Features:

The DSR1 comes pre-programmed for 2014-2018 Harley-Davidson Infotainment radios with only the front channels enabled. This means for many users, it's a plug-and-play solution requiring minimal setup. For 2019 and newer Harley-Davidson GTS radios, a specific setup file needs to be downloaded and loaded onto the DSR1 using the Perfect Tune app. If no factory radio is used, the EQ can be reset to flat within the DSR1 app, allowing for custom adjustments.

The device is designed to be user-friendly, with the latest firmware already installed, eliminating the need for computer connection for updates. The pre-loaded setup file, "14_6channel_Out_1.rfts," configures the DSR1 for a typical 2-channel input (front only) from a factory radio, with 6 output channels (front, rear, sub) activated. This configuration is common for most users.

The DSR1 features both "Basic Tune" and "Advanced Tune" equalization sections within its app. For most users, it's recommended to stick to the 7-band "Basic Tune" EQ for adjustments, as the "Advanced Tune" is pre-set and intended for experienced users. Altering advanced settings without proper understanding can lead to undesirable audio results. The setup wizard in the DSR1 app should generally be avoided unless specific input/output changes are required, as opening it can inadvertently erase the pre-programmed settings.

A critical aspect of DSR1 usage, particularly with factory radios, involves the remote turn-on connections. The DSR1's blue/white wire serves as a delayed remote output for amplifiers, preventing the "turn-on pop" often experienced with factory Harley radios due to their long boot times. It is crucial to connect the DSR1's blue/white wire to the amplifier's remote input and never connect the radio's blue/white wire directly to the DSR1's blue/white wire, as this can damage the DSR1 and the radio. For aftermarket radios, the radio's amplifier remote turn-on wire (usually blue or blue with white stripe) should connect to the DSR1's solid blue wire (remote in).

The DSR1 has 8 RCA outputs, though many installations will only require a subset of these. The outputs are clearly labeled (Front, Rear, Subwoofer) and are full range with a 31-point Anti-EQ applied for factory Harley Infotainment radios. While all 8 channels are configurable, it's recommended to use the designated outputs (e.g., front for front speakers) for easier tracking within the DSR1 app.

Crossovers are built into the DSR1, but it is generally recommended to use the crossovers built into the amplifiers instead, unless the installer is highly familiar with complex DSP crossover settings. All speakers in a motorcycle audio system should have high-pass crossovers properly turned on and set.

The DSR1 also includes trim levels for each channel and a master volume control, intended for advanced users. For optimal gain staging, it's recommended to turn all DSR1 trim levels all the way up and set amplifier gains directly on the amplifiers themselves.

Maintenance Features:

While the document doesn't explicitly detail "maintenance features" in the traditional sense (like cleaning or part replacement), it emphasizes proper installation and configuration as key to the device's longevity and performance.

• Firmware Updates: The DSR1 ships with the latest firmware, reducing the need for immediate user intervention. However, future firmware updates, if released, would likely be handled through the Perfect Tune app, ensuring the device remains current with any improvements or bug fixes.
• Setup File Management: For specific radio types (e.g., 2019+ GTS radios), users are guided to download and load specific setup files from the manufacturer's website. This ensures the DSR1 is correctly configured for different vehicle models and prevents potential audio issues.
• Troubleshooting "Turn-On Pop": The document provides a detailed explanation and solution for the common "turn-on pop" issue, which is a form of audio system maintenance. It highlights the DSR1's delayed remote output as a primary solution. If the pop persists, it suggests adding an external delay device like a Pac Audio TR4, complete with wiring diagrams, to further manage the electrical system's power-up sequence. This proactive guidance helps users maintain a clean, pop-free audio experience.
• Wiring Best Practices: The guide stresses the importance of correct wiring, particularly for remote turn-on connections and power/ground. It advises using bullet connectors, heat shrinking or taping off unused RCA ends, and fusing power connections to prevent electrical shorts and damage to the DSR1 or other components. Improper wiring, especially for remote in/out connections, can void the warranty, underscoring the importance of following the provided instructions for device longevity.
• DC Detect Feature: The DSR1 utilizes a "DC detect" feature, which listens for music signals from the factory radio outputs to automatically turn on the DSR1. This eliminates the need for a separate remote turn-on wire from the radio, simplifying installation and preventing turn-on pops. This feature is enabled on every DSR1 sold, contributing to a more reliable and maintenance-free operation in specific setups.

In essence, the DSR1's "maintenance" largely revolves around correct initial setup, understanding its operational nuances, and utilizing the provided resources (app, website articles) to ensure optimal and trouble-free audio performance.
