Overview

Introduction

The dbx® goRack™ is an easy-to-operate portable loudspeaker processor. Based on our industry-leading DriveRack® Series processors, the goRack sits next to a set of powered speakers and provides powerful signal processing, including Anti-Feedback, Compression, Subharmonic Synthesis, and EQ. Each processing function can easily be enabled or disabled via the top-panel buttons, and settings can be adjusted via the goRack’s large rotary encoder.

The goRack can be used to provide loudspeaker processing in a conventional sound system by placing it between the mixer and powered speakers/amplifiers or as a stand-alone 2-channel mixer/loudspeaker processor, making it ideal for band rehearsal spaces, live performance of solo artists or duos, weddings, or speech/presentation applications.

The goRack’s rear panel houses combination 1/4” / XLR inputs that can be connected to either mixer outputs, or straight to instrument or microphone outputs. The Mic/Line switch on each input selects the proper input sensitivity while dual gain controls on the top panel provide independent level adjustment. The goRack’s stereo 1/8” Mini Aux Input allows for direct connection of a mobile device or portable music player. The XLR outputs allow for interfacing with powered speakers or stand-alone amplifiers.

The goRack represents the best of dbx’s DriveRack processing in its purest, most simplified form, all housed in a sleek, compact form factor that fits in your hand, or back pocket.

Thanks for choosing dbx.

Adjust these gains to optimize the signal levels for the main LEFT/RIGHT inputs. The MIC/ LINE switches on the rear panel should be set to the correct position for the application before adjusting these knobs.

NOTE: AUX INPUT signals are not affected by

the Input Gain knobs.

4. INPUT SIGNAL LEDs

These multi-colored LEDs display the input signal level strength and available headroom.

Indicates signal is present.

Orange

• Indicates the signal level is approaching the headroom limit.

• Red Indicates the input signal is clipping and the input gain should be reduced.

5. 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. See ‘Configuring The goRack’s Routing’ on page 6 for more information on the routing options available in the goRack.

1. LEFT / RIGHT Combination Input Jacks

Connect your mixer, microphone, or instrument outputs to these combination 1/4” / XLR input jacks. The input sensitivity of these jacks are set using the MIC/LINE switches next to each jack and the input gain can be adjusted using to the top-panel LEFT/RIGHT input gain knobs.

The input signals can be routed in stereo or mono summed to the output jacks. See ‘Configuring

The goRack’s Routing’ on page 6 for

more information on the Routing modes available in the goRack.

2. MIC / LINE Switches

Match these swtches to the type of connections being made to the input jacks. Select the LINE option when connecting the outputs of a line-level device, such as a mixer or the output of an instrument with a built-in pickup. Select the MIC option when connecting a microphone.

3. AUX INPUT Jack

Connect a mobile device or portable music player to this 1/8” (3.5mm) stereo Mini jack. There are a couple of different processing routing options available for this jack (see ‘Configuring The goRack’s Routing’ on page 6 for more information).

4. XLR Output Jacks

Connect these electronically balanced XLR outputs to the amplifier or powered speaker inputs.

5. DC Power Input Jack

Connect the included Harman power adapter to this power input jack.

6. Power Adapter Cord Retaining Clip

Route the power adapter cord through this retaining clip to prevent accidental removal of the power plug (see ‘Applying Power’ on page 5 for more information).

Making Connections

Audio Connections

1� Ensure the power is turned off on all interconnecting equipment and the goRack before making audio connections.

2� Connect the outputs of the mixing console, microphones, or instruments to the inputs of the goRack and set the goRack’s

MIC/LINE input switches accordingly. Use the highest quality cable available with the shortest possible cable runs.

3� Connect the goRack’s outputs to the amplifier or powered speaker inputs.

TIP: See ‘Application Diagrams’ on page 22 for application notes and system diagrams which can be used for

reference when connecting the goRack to your system. See ‘Audio Cable Diagrams’ on page 26 for information on cable wiring.

Applying Power

1� Ensure your power amplifiers or powered speakers are turned off. 2� As shown in the illustration to the right, pinch the power adapter cord together, leaving

approximately 2 inches of cable before the power plug, then route the cord into the cord retaining clip on the goRack’s rear panel.

3� Connect the power adapter jack to the DC power input.

4� Apply power to the goRack by connecting the other end to an available AC power outlet. Since

the goRack does not have a power switch, an AC power strip or power conditioner can be used for switching power to the goRack on or off.

5� Apply power to your mixer then your power amplifiers or powered speakers.

WARNING! When powering up a fully connected PA system, it is advisable to ALWAYS turn on the goRack (and

mixer if applicable) first then turn on your amplifiers or powered speakers last. It’s also a good idea to ensure the goRack VOLUME or mixer output gains are reduced before applying power to the amplifiers. When powering down the system, you should ALWAYS power down the amplifiers/powered speakers first, wait about 10 seconds to allow them to discharge, then power down the goRack (and mixer if applicable). In short, every time you use your system, the power amps should be the last components turned on and the first components turned off.

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/presentation applications.

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.

This option mono sums the MIC/LINE inputs just like option 1, but maintains stereo imaging in the AUX INPUT. It also moves the Subharmonic Synthesis processing and adds EQ processing to 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.

Properly setting system levels will help keep distortion and noise levels down, improve anti-feedback operation, and provide ample headroom for clean and safe operation of the sound system.

To set system levels:

1. Turn down your amp or powered speaker levels. If your powered speakers have Mic/Line switches, set them to “Line”.

2. Make sure all processors are turned off.
