Scope
This document covers usage of the Mini Mixers found in Axia Altus
Description
Each instance of Altus comes with 8 Mini Mixers (formally known as V-Mixer). Each Mini Mixer has 5 inputs and 1 output. The Mini Mixer allows you to do simple utility summing and can be controlled with Livewire GPIO
How to configure and use
Source Profiles
Before using the Mini-Mixer you need to create Source Profiles. If you have already been using Altus, chances are that several Source Profiles already exist A word about Source Profiles with Mini-Mixer. Unlike console faders, inputs on the Mini-Mixers do not engage console DSP. Which means, Source Profile controls and options like Signal Mode, Phase, Input Trim, Dynamics, EQ and Backfeeds do not occur when loaded to Mini-Mixer inputs | Only options in green are referenced when Source is loaded to Mini-Mixer inputs |

To configure the Mini Mixers go to the Mini-Mixer & V-Mode page |

Assigning Source Profiles to Inputs
Use the Source drop down menu to select which source to assign to each Mini Mixer input. | |
---|---|
It is not required to use all 5 inputs if not needed |
Adjusting Input ON/OFF and Gain
Each input can be turned on or off. Turn on any inputs that you want to mix together Each input has additional gain adjustment that can be applied. Maximum gain applied is +10dB and the minimum gain applied is -80db |
---|
Adjusting Output Gain
The gain adjustment in the upper right is the mixer output. Adjust this to raise or lower the overall gain of the mixed inputs |
---|
Receiving Mini Mixer output to Altus Mixer
It is possible to receive any Mini Mixer output back as a fader on the Altus mixer
|
---|
Sending Mini Mixer output to the network
The mixed output of any Mini Mixer can be made available as a Livewire channel or AES67 multicast stream.
|

Sending Mini Mixer output to webRTC monitor
If Altus was configured with a working Beacon server, you can also provide the Mini Mixer output as a sharable webRTC monitor session. This will allow a remote person to listen to this output anywhere via the internet

More: Controlling Mini Mixer with Livewire GPIO
The ON/OFF states of each input for each Mini Mixer can be controlled and monitored using Livewire GPIO
When the Control Type is set to Normal, Toggle or Radio options, this enables Livewire GPIO control over the Mini Mixer Set the Logic Port field to an unused Livewire channel number, and use this channel number as the address in an Axia GPIO port |
---|
Note about Livewire GPIO. The Logic Port field is using the Livewire channel number to identify the virtual input and output logic pins associated with Mini-Mixer. This channel number can be assigned as the address on GPIO ports found in Axia products such as Livewire IP Driver, xNode’s and Pathfinder. Each GPI pin # corresponds to the Mini-Mixer input #. Each GPI pin controls the ON/OFF states of the inputs. The Control Type determines how the GPI will influence the ON/OFF states of the inputs. The GPO’s always represent the current input ON/OFF states (Low = ON, High = OFF)
Typical ways to interface:
Wire up physical push buttons and indicators to an xNode GPIO port to control the Mini-Mixer using physical GPIO
Interface it with compatible automation software (via Livewire IP Driver) to let it control the Mini-Mixer using virtual GPIO
Interface it with Pathfinder CorePRO’s own virtual GPIO node and control it in a large number of different ways
