Routing OperationalOverview.png

Routing I/O

The X32 RACK console features 16 analog rear-panel XLR inputs with microphone preamps, as well as 8 rear-panel XLR Outputs and 6 TRS Aux Sends and Returns. In addition, there are two AES50 ports, each featuring 48 input and output channels, and a card slot for 32 channels of input and output to and from a connected computer via USB 2.0.

Input Signals can be attached to the console’s internal audio processing engine in blocks of 8 signals from any one of the aforementioned input sources.

Note: All signal blocks patched to the audio processing will be connected to the corresponding input channels automatically.

Local inputs 17-24 and 25-32 are listed with brackets, indicating that these are not physically available on this device. Assigning these will obviously carry no signal, but they can still be used when preparing shows for a full X32 console.

Cabling for AES50 connections between X32 and S16 stageboxes:

  • Shielded Cat-5e cables only
  • Ethercon terminated cable ends
  • Maximum cable length 100 meters (300 feet)




OutputSignal OperationalOverview.png

Output Signals can be freely assigned from any internal signal to any of the following outputs:

  • 8 analog local XLR outputs (with adjustable digital delay for time-alignment of speakers)
  • 8 virtual outputs (marked with *) for routing over AES50 or card outputs
  • 6 auxiliary sends on ¼" TRS outputs
  • 16 channel personal monitoring using the console’s P-16 Bus output connector

Any and all of the above signals can also be mirrored in blocks of 8 signals on either one of

  • 48x channels on AES50 port A
  • 48x channels on AES50 port B
  • 32x channels on USB interface card




InputConfig OperationalOverview.png

Input Channels 1-16 are pre-configured to use the local input signals 1-16, but can be patched to use any other available signal on the audio engine as well, including mix bus/sub group outputs. Changes of the Channel Source can be made on the Preamp Config page.

Input Channels 17-32 are pre-configured to AES50 A inputs 1-16, so that connecting an S16 stage box to port A will automatically feed the channels.

Aux Return Channels 1-8 are pre-configured to use the 6 aux input signals, and the two USB playback outputs, but can be patched to use any other available signal of the console as well.

FX Return Channels 1L-4R control the 4 stereo output signals of side-chain FX1-4.




InputConfig2 OperationalOverview.png

The configuration of Mix Bus Channels 1-16 can be pre-set (in the Setup/Global page) or can also be configured on an individual, per-channel basis. The bus processing includes (in this order):

  • Insert point (swappable between post-EQ and pre-EQ operation)
  • 6-band fully parametric EQ
  • Compressor/expander (swappable between post-EQ and pre-EQ operation)
  • Bus sends to 6 matrices
  • Main LR panning
  • Mono/Center level

Main Bus Channels LR/C are always available and independent from Mix Buses. The processing steps for this signal path include (in this order):

  • Insert point (swappable between post-EQ and pre-EQ operation)
  • 6-band fully parametric EQ
  • Compressor/expander (swappable between post-EQ and pre-EQ operation)
  • Bus sends to 6 matrices

Matrix Channels 1-6 are fed exclusively by MAIN LRC and Mix Bus 1-16 signals. The processing steps include (in this order):

  • Insert point (swappable between post-EQ and pre-EQ operation)
  • 6-band fully parametric EQ
  • Compressor/expander (swappable between post-EQ and pre-EQ operation)

Effects Processing 1-8 The X32 RACK contains eight true-stereo internal effects engines.

  • FX 1-4 can be configured as side chain or insert effects, while FX 5-8 can only be used in insert points of channels or buses
  • The FX Home screen allows selection of the FX 1-4 input sources and selecting the effects type/algorithm for each of the 8 FX slots of the virtual rack
  • The subsequent tabs FX 1-FX 8 of the FX screen allow editing all parameters of the chosen effects processor

iPad App for X32 RACK Many functions of the X32 RACK console can be remotely controlled by a dedicated iPad app.

The app’s User Interface is optimized for the touchscreen nature of the iPad device and concentrates on the most important remote features of the console only. Using the app, you can perform functions such as adjusting monitor mixes from the stage while interacting with musicians, or adjusting the front-of-house mix from the audience, while hearing the mix exactly as the audience does.

Linux/OS X applications and Windows-based applications for X32 RACK Also offered is a separate remote editor running on host computers that will allow for complete editing control of the X32 RACK via Ethernet.

Tip: The X32 RACK remote communication is OSC-based (open sound control) and we will share the protocol on our website, allowing developers to design their own control software. Stay tuned to behringer.com for details on the OSC protocol.


X-USB expansion card The X-USB card allows transmission of up to 32 channels to and from a connected computer. Please download the X-USB drivers and Quick Start Guide from behringer.com before connecting the mixer to your computer. The card is CoreAudio compatible, allowing it to work with computers with the OS X operating system software of Apple, Inc. without a driver.




ChannelMenu OperationalOverview.png

Main Display Area The top section of the main display permanently covers useful status information. The top left corner shows the selected channel number, its nickname and the selected icon. The next block shows the current scene number and name in amber, as well as the next upcoming scene. The center section displays the playback file name along with elapsed and remaining time and a recorder status icon. The next block to the right has 4 segments to show the status of AES50 ports A and B, the Card slot and the audio clock synchronization source and sample rate (top right). Small green square indicators show proper connectivity. The right most block shows the console time that can be set under Setup/Config.

When working with any given screen, press the Page keys located on the display bezel to switch to different screen pages.

Editing parameters or settings on each of the screens is done using the 6 associated push-encoders along the bottom edge of the display.

  • Whenever there is a continuous control or list entry, you can turn the corresponding knob for editing, which is indicated by various circular icons
  • When there is a switch or toggle function on one of these knobs, you will see a broad rectangular button along the lower edge of the field. Pressing the encoder changes the on/off state of the corresponding function. When the rectangular button in the display is dark grey, the corresponding function is off/inactive; when it is amber, the function is on/active


Customizing the X32 RACK through the Utilities page Press the Utility button, located to the right of the main display, to bring up useful functions in a “context-sensitive” manner. For example:

  • When you are adjusting the equalizer of a console channel, pressing the Utility button will offer copying, pasting, loading or saving of equalizer settings
  • On the Routing pages, pressing the Utility button will offer loading or saving different presets of routing scenarios
  • In the Scenes menu, pressing the Utility button offers copying, loading, saving or naming console scenes

NOTE: The X32 RACK DCA groups can be selected using the Channel Select control in order to adjust their fader level, mute or solo status. Note, however, that the main display will remain focused on the last real channel (bus or input) that was selected before DCA, since DCAs do not feature any processing.


Startup and Shutdown, and Update: We recommend switching the X32 RACK mixer on first, and shutting it off last when any sound system is connected. This will prevent the possibility of any unexpected noises being transmitted during the startup/shutdown process.

The Setup screen’s general preference page contains a Safe Main Levels function. When activated, the console automatically mutes the main LRC levels when booting the console. It also prevents any scene loading from affecting (i.e. turning up) the mains levels.

Synchronization and Sample Rate settings for the console can be adjusted on the Setup/Config page, but please note that sample rate changes will require a reboot of the console. When you see a red square indication at the top section of the main display, please verify if the synchronization settings on Setup/Config make sense.

RACK startupshutdown.png

In order to prevent any errors by losing power during a store operation, we recommend using the “Safe Shutdown” function from the Setup/Global page.

NOTE: The X32 RACK can be locked against unintended use by activating ‘Lock Console’ from the Setup/Global page. In this state the UI will not allow any changes to be made and the display shows “X”. Keep HOME depressed for about 5 seconds to unlock the X32 again.

The X32 firmware can easily be updated by performing the following steps:

  • Download the new console firmware from the X32 RACK product page onto the root level of a USB thumb drive
  • Plug the USB thumb drive into the front panel USB connector while the console is turned off
  • Hold the USB button depressed while switching the console on. While booting, the X32 RACK will run a fully automatic firmware update, which will take 2-3 minutes longer than the regular boot sequence

When no update file is available on the USB drive, or when it is corrupted, the update mode will remain active, preventing the X32 from booting regularly. Switch the console off and back on without holding the USB button to boot the console with the existing firmware.

CAUTION: Please do not block the vent openings on the sides of the X32 RACK cabinet! Specifically when mounting the X32 RACK in a road case, please ensure there is sufficient space to allow for some airflow.
