Audio signal flow
This page explains how audio signal flows from the AoIP standards to HOLOPLOT's Audio Modules in OS 2.0. We will continue using the same project example from the previous page, and will examine one preset in particular.
Main components
The chart below explains the main components and their relationships: Audio inputs, beams, modules/arrays, and AoIP channels and streams. Here is a quick recap:
Beams, arrays, and modules
A group of modules forms an array. Beams are connected to Audio Module(s). Audio Modules can have multiple beams, as exemplified by the Audio Modules in the front fill array. Each beam has its own individual DSP, including user-adjustable gain, delay, and EQ.
Audio inputs, beams, and presets
Beams are connected to audio inputs on preset layers/presets. Meaning, that their assignment can vary depending on the needs.
You can connect multiple beams to the same audio input and multiple audio inputs to the same beam. The connection between audio inputs and beams can have an optional gain value, which is set by default to 0 dBFS.
AoIP channels and streams and audio inputs
The previous two topics are defined inside HOLOPLOT Plan. The actual connection between your Dante or Ravenna audio channels and audio inputs happens inside HOLOPLOT Control. As the example above shows, an audio input can be fed from multiple sources.
Audio controls and metering
Different places in the audio flow can be monitored and controlled in HOLOPLOT OS 2.0 with HOLOPLOT Control.
Audio controls
You can mute/unmute, solo/unsolo, adjust gain and delay, and apply EQs on the beam level.
On the system level, you can mute/unmute, adjust the gain, and apply EQs.
Metering
There are meters for outputs and inputs. Outputs are modules, arrays, and system. Inputs are beams.

Putting it all together
Now that the audio flow concepts are laid out let's examine some examples.
The chart above shows what audio inputs, beams, and modules will receive audio from the AoIP channel DANTE 01. Remember that each beam has individual DSPs and will process that signal accordingly.
We can take it one step further, and solo one of the beams. This is especially useful for tuning and debugging.
