Processor Setup

The HOLOPHONIX processor is designed to work around digital networks:

  • it relies on the Dante™ audio network for inputs and outputs,
  • the processor’s web-based user interface can be accessed via a web browser on a computer connected to the same local area network,
  • every parameter of the processor can be controlled via the network-based Open Sound Control protocol.

Because the user interface is hosted in the processor and accessed via a web browser, the user doesn’t need to install any software on his computer to control the processor. This allows a total cross-platform use, and avoids any software version incompatibility. All the sessions and parameters are stored locally inside the processor.

The processor booting is a fully automated process, requiring no user input. Once the starting phase is done, the processor is ready to use.

Initial Setup

Remote Control

The user can access the web interface either in 'local' mode (directly on the processor by simply plug-in a computer screen, keyboard and mouse), or in “remote” mode, with any computer connected to the same network as the processor.

On your web browser, just enter one of the theses options to access the web interface:

  • http://holophonix.local/
  • your processor's IP address

The We recommend using the web browser Google Chrome™. See Network Settings to learn how to set up your processor’s IP address.

If you only want to control the processor in 'local' mode (i.e., not from a remote computer), you can also connect a keyboard, a mouse and a monitor directly to your HOLOPHONIX processor. This activates the powerful graphic chips of the internal video card, allowing you to work with a maximum resolution of 5K.

Power-Off and Restart

To power off or restart your station, go to the Preferences View, then select the 'Misc' tab, and choose the Power-Off or Restart options.

Power Button

Press on the processor front panel button to switch your HOLOPHONIX station on or off. To avoid accidentally switching off the processor by pressing this button, a 60-second countdown is programmed. So, as soon as the button is pressed, you have 60 seconds to cancel the power-off procedure.

IEC C14 Socket

According to the chosen setup, your HOLOPHONIX processor features one or two IEC C14 mains socket(s) on its rear panel. Connect the supplied cable(s) to the socket(s), then to the mains outlet. It is strongly recommended to power the HOLOPHONIX processor via an UPS/inverter system (Uninterruptible Power System), to ensure protection, backup power and automatic voltage regulation. If your processor is equipped with redundant power supplies, an alarm sounds in case one of the power supplies fails.

Gigabit (1Gbps) Dante® Ports

The HOLOPHONIX processor handles 256 Dante® channels (128 in x128 out) with up to a 96 kHz resolution. It is equipped with both a Primary (P) and a Secondary (S) port, for redundant connections ensuring a maximal reliability.

Connect the Dante® Primary and Secondary ports on your Dante® network’s primary switch and secondary switch, respectively. Use Gigabit Ethernet network switches, optimized and setup for Dante®.

Download and install the Dante® Controller software on an external computer (macOS® or Windows®) to configure the Dante® parameters of your HOLOPHONIX Processor, and assign the receive (Rx) and transmit (Tx) channels to your audio system.


Always follow Audinate®'s recommendations to set up your Dante® system at

Primary & Secondary Ports Status LEDs

The 'Gigabit Link Status LED' is orange when a Gigabit Ethernet link is established.

The 'Activity & Link Status LED' is green when a link is established, and flashes to indicate activity.

Dante® Status LEDs

The Dante® network card integrates three status LEDs labeled 'ERR', 'SYNC', and 'SYS', reporting the device's system and clock synchronization status. SYS reports the status of the Dante® system on this card:

  • it is orange when the system is booting;
  • it turns green when the system has booted successfully and is operating properly,
  • if it persists to light orange, the system has failed to boot correctly.

SYNC reports the clock synchronization status of the Dante® device:

  • it is green (not flashing) if the device is synchronized to the PTP clock master (the device is a clock slave),
  • it is flashing green if the device is the PTP clock master,
  • it is orange if a network synchronization error occurred; obtaining a network synchronization can take up to 45 seconds.

All the LEDs will flash green when the 'IDENTIFY' function is activated from the Dante® Controller software.

If all the LEDs are flashing red, it indicates that errors have occurred on boot and that the Dante® system has entered 'failsafe' mode. Contact Amadeus for service instructions.

Ethernet Ports (RJ-45) #1-2-3

Connect your processor to your local area network for remote control (via the web interface), to send and receive OSC messages, and for internet access.

Ports #1 and #2 offer a gigabit connection (1 Gbps). Port #3 can offer up to a 10 Gbps data rate (with compatible network infrastructure).

It is recommended to use only one Ethernet Port on the processor for remote control, OSC and the internet. If the internet access is on a different network, you may use a second port. However, it is recommended to keep remote control and OSC together.

Use a high-speed (broadband) internet access point.

USB 3 Ports

These USB 3 ports on the rear panel allow connecting your control accessories quickly and easily.

To use your HOLOPHONIX station, you need two accessories: mouse and keyboard (not supplied).


The HOLOPHONIX processor hosts a powerful graphic card, equipped with four DisplayPort 1.4 ports. It is able to handle three 5K screens (5120 × 2880 pixels) with a 60 Hz refresh rate.

Connect a monitor to one of these ports to access the server interface of HOLOPHONIX for setup and maintenance operations.
