Introduction to Sources

The sources receive the audio coming from the Dante Inputs, then go through one or several spatialization algorithm bus(es). They offer an audio channel strip with several parameters to mix the sources. Each source encloses six panning modules, linked to the selected spatialization algorithm bus. Therefore, a source can be assigned to a maximum of six buses simultaneously.

HOLOPHONIX gives you access to three categories of sources listed below.

Virtual sources

Virtual sources represent physical objects that emit sound into space. They are made of one or more (stereo, multichannel) audio source(s), and can be freely positioned around the audience. Those sources include an acoustic simulation module (with reverberation), that can be automatically controlled by the position of the source.

Audio streams

Stream sources are designed to receive audio encoded in a specific format. Audio stream sources are mainly composed of different types of Ambisonics streams, but also include custom microphone layouts (Mic Tree). Unlike virtual sources, they do not represent a physical object in space (except for Mic Tree); therefore they do not have any associated object in the 3D VENUE view.

Direct routings

They offer the possibility to connect audio inputs to buses or to loudspeakers directly.

Main Settings


Check the Equalizer page for more details.


Use the trim to adjust the level of the source between -80dB (no signal) and +30dB. The trim function is especially useful to minimize the level differences between the sources.


You can then use the Gain to mix source levels. It ranges from -60 dB (no signal) to +12dB, and can be accessed via the Mixer view, with faders.


Use the mute function to cut the audio of a source. When a source is muted, its computation is deactivated, thus saving processing power.

Audio Parameters


Activate Solo on a source to listen to that source only. It can be activated on multiple sources at the same time.

To clear all active solos, use the Solo Clear button in the options bar.

LFE Send

LFE Send allows you to set the amount of signal to send to the LFE Bus. Sources contaning multiple channels (Stereo, Multichannel, Mic tree and Direct Routings) will send a mono sum of all their channels to the LFE. Ambisonics sources, will only send the W-Omnidirectionnal channel.

The signal is sent after the channel's Gain, Mute parameters, as well as the Direct send for virtual sources. However, the Direct Mute parameter has no effect on the LFE Send .

LFE Mute

Use the mute button to deactivate the LFE Send on the source.
