The dbx goRack is the easiest, most compact way to get

the most out of your PA system. All the processing you'll

need for clear, powerful live sound is packed inside.

  • Introduction

    The dbx® goRack™ is an easy-to-operate portable loudspeaker processor. Based on our industry-leading DriveRack® Series processors, the goRack provides all the signal processing you'll need to optimize and protect your small PA or powered speakers. Processing features include:

  • Mute (Mode) Button

    Pressing this button will mute/unmute the goRack’s outputs. Pressing and holding this button for 2 seconds enters Routing mode (indicated by a flashing LED), where you can select a routing option by rotating VOLUME (EDIT) encoder.

    ROUTING MODE HOME
  • Mono Routing Configuration

    01 MONO

    This is the default setting. This option mono sums all input signals and feeds them to both outputs. This option is ideal for the solo artist or duo. For example, one input could be used for connecting a microphone and the other for an instrument, such as an acoustic guitar with a built-in pickup. This option is also well suited for speech or presentation applications.

  • Stereo Routing Configuration

    02 STEREO

    This option maintains stereo imaging through the goRack. Select this option when connecting the goRack between the mixer and powered speakers or amplifier in a conventional, stereo PA system.

    NEXT ROUTING OPTION HOME
  • Advanced Routing Configuration

    03 ADVANCED

    This option mono sums the MIC/LINE inputs just like option 1, but maintains stereo imaging in the AUX INPUT. Use this option when you don’t want signals connected to the MIC/LINE inputs to be processed with Subharmonic Synthesis and want to add equalization to the AUX INPUT signal.

    HOME
  • Anti-Feedback

    Feedback is caused when an in-phase audio loop is created between an input transducer (such as a guitar pickup or microphone) and an output transducer (a loudspeaker). The goRack includes the exclusive AFS® (Advanced Feedback Suppression) algorithm to help combat it. The 10 Live AFS filters will automatically detect and suppress feedback.

    Available Anti-Feedback Options

    The goRack provides three different Anti-Feedback modes, each designed for specific audio content.

    Pressing this button will enable Anti-Feedback. Pressing and holding it for 2 seconds allows you to choose from three different AFS modes.

    EDIT AF HOME

  • Music (Narrow Notch) Anti-Feedback

    01 MUSIC (NARROW)

    This option is optimized for live music sound reinforcement and offers the highest level of sonic quality. When this option is selected, the AFS algorithm will zero in on the offending feedback frequency, while leaving the surrounding frequencies unscathed.

    NEXT AF OPTION HOME
  • Music/Speech (Medium Notch)
    Anti-Feedback

    02 MUSIC/SPEECH (MEDIUM)

    This option is optimized for live music or speech and will provide the best combination of fast feedback suppression and precision. If you’re not sure which setting to use or the system is being used for music and speech sound reinforcement, select this option.

    NEXT AF OPTION HOME
  • Speech (Wide Notch) Anti-Feedback

    03 SPEECH (WIDE)

    This option is optimized for speech sound reinforcement, where wider notch filters are less noticeable. Select this option when using the sound reinforcement system for speech only. With this option selected, notch filters will be wider, but will provide the fastest, most solid protection against feedback.

    HOME
  • Compressor

    A compressor is used to compress the dynamic range of the audio signal.

    The compressor in the goRack is modeled after the dbx 163 analog compressor. It is a soft-knee (OverEasy®) compressor with a fixed ratio of infinity:1, program-dependent auto attack and release times, and one parameter which affects both the threshold and makeup gain.

    Pressing this button will enable the Compressor. Pressing and holding it for 2 seconds allows you edit the Compressor settings.

    EDIT COMPRESSOR HOME
  • Compression Levels 1-99

    1-99 COMPRESSION AMOUNT

    Adjusts the amount of compression applied, with 1 being essentially no compression and 99 being the maximum amount of compression. You can increase or decrease the compression amount by rotating the VOLUME (EDIT) encoder.

    HOME
  • Subharmonic Synthesizer

    dbx Subharmonic Synthesis (or Sub Synth) processing has been specifically optimized to enhance the low frequencies in audio material and was designed for use in a variety of professional audio applications, including nightclub and dance DJ mixing, theatre and film sound, sound design, music recording, live music performance, and broadcasting.

    Sub Synth looks at frequencies around 100 Hz in the audio and creates synthesized frequencies an octave below, providing noise-free low-end enhancement that people can really feel!

    Pressing this button will enable Sub Synth. Pressing and holding it for 2 seconds allows you edit the Sub Synth amount.

    EDIT SUBSYNTH HOME
  • Sub Synth Levels 1-99

    1-99 SUB SYNTH AMOUNT

    Adjusts the amount of Subharmonic Synthesis effect added to the signal, with 1 being essentially no effect and 99 being the maximum amount of effect. You can increase or decrease the compression amount by rotating the VOLUME (EDIT) encoder.

    HOME
  • Equalizer

    Various factors will determine how a sound system will sound in a room, such as the frequency response of the speakers, the frequency response of any microphones or instruments used, and the room acoustics to name a few. The goRack has 16 EQ preset curves to select from. These EQ preset curves can be used to quickly tune the frequency response of the sound system to help compensate for some of these limitations and help improve clarity and impact.

    Pressing this button will enable the Equalizer. Pressing and holding it for 2 seconds allows you select from 16 different EQ settings.

    EDIT EQ HOME
  • Bass Boost

    01 BASS BOOST

    This EQ curve can help when the system sounds “thin” and lacks “body” and is similar to raising the LOW tone control on a stereo system.

    NEXT EQ OPTION HOME
  • More Sub

    02 MORE SUB

    Select this curve when the system has body but lacks definition in the bass.

    NEXT EQ OPTION HOME
  • Venue

    03 Venue

    This EQ curve works well when the system is slightly “bright” and the bass frequencies are lacking. Try this curve when the room is a bit reverberant due to brightly reflective surfaces, such as windows.

    NEXT EQ OPTION HOME
  • EDM/Pop

    04 EDM/Pop

    This curve provides enhanced bass and treble frequencies with a midrange scoop and is well suited for Electronic Dance and Pop Music or DJ use. This is the classic “smiley face” EQ curve.

    NEXT EQ OPTION HOME
  • Deep

    05 DEEP

    This EQ curve will enhance the bass while simultaneously scooping out some lower-midrange “mud” and slightly reducing the midrange and treble frequencies, providing a deeper, sub-bass sound.

    NEXT EQ OPTION HOME
  • Treble Cut

    06 TREBLE CUT

    Select this curve to tame treble frequencies when a system sounds overly “bright” and “harsh”. It is similar to lowering the HIGH tone control on a stereo system.

    NEXT EQ OPTION HOME
  • Acoustic

    07 ACOUSTIC

    This curve is optimized for live reproduction of an acoustic guitar performance.

    NEXT EQ OPTION HOME
  • Rock

    08 ROCK

    This curve is well suited for the reproduction of a live rock music performance.

    NEXT EQ OPTION HOME
  • Loudness

    09 LOUDNESS

    This EQ curve can be used to balance the system when operated at louder levels.

    NEXT EQ OPTION HOME
  • Mid Boost

    10 MID BOOST

    This EQ curve can help add midrange definition to a sound system that lacks it.

    NEXT EQ OPTION HOME
  • De-Mud

    11 DE-MUD

    This EQ curve can reduce “mud” which can build up around the 300 Hz region.

    NEXT EQ OPTION HOME
  • Speech

    12 Speech

    This curve can help reduce low-frequency noise and increase intelligibility in systems reproducing speech only.

    NEXT EQ OPTION HOME
  • Mid Cut

    13 MID CUT

    This curve can help tame a system that sounds “boxy” or has excessive midrange frequencies and make it sound more musical.

    NEXT EQ OPTION HOME
  • Bass Cut

    14 BASS CUT

    Select this curve to tame bass and lower-midrange frequencies when a system sounds “boomy” and “muddy” and is similar to lowering the LOW tone control on a stereo system.

    NEXT EQ OPTION HOME
  • Jazz

    15 JAZZ

    This curve is optimized for the reproduction of a live jazz performance.

    NEXT EQ OPTION HOME
  • Treble Boost

    16 TREBLE BOOST

    This curve can help add top-end “air” and “clarity” to a speaker system that lacks it and is similar to raising the HIGH tone control on a stereo system.
