Audio Interfaces
Livewire+ AES67 microphones for camera switching
Livewire+ puts every microphone in the studio on the network as AES67. VRA cuts the cameras from those channels once an AES67 driver on the Audio Manager machine receives them, and it can read the console's GPIO over LWRP on the same network.
What VRA does with Livewire+ AES67.
Recognised by name
There is no device called AES67 to recognise. VRA recognises the drivers that receive it: RAVENNA Receive and RAVENNA ASIO, Merging Audio Device and the Digigram ALP-AES67.
Pairs or one ASIO block
RAVENNA Receive and the Digigram card arrive as stereo pairs, which VRA orders and splits into single channels. Merging and RAVENNA ASIO arrive as one device that carries every channel.
A trigger per microphone in one step
Accept the detected setup and choose how many channels to cover. VRA creates a trigger per channel, already bound to its device and channel, each with a placeholder command you swap for a camera angle.
Cameras cut to whoever is talking
When a mic passes its threshold, its trigger fires the camera angle, macro or playout command you gave it. Calibration measures the room's floor and the presenter's level, then sets the threshold from the gap between them.
No AES67 receiver in VRA
Audio Manager does not join an AES67 stream itself. A card or driver on the machine has to receive it first.
How to set it up.
Requirements
- Audio Manager on a Windows or macOS machine that can open the AES67 device.
- The AES67-compatible interface and its Windows driver installed and working in the operating system.
- The microphones already routed to those receive channels on your console or audio network.
Install the AES67-compatible interface and its Windows driver on the Audio Manager machine and route the studio microphones to its receive channels.
Start Audio Manager and check that the channels appear in the studio's audio devices.
In Audio Triggers, accept the detected setup and choose how many channels to cover, or map the channels by hand. Each trigger is bound to its channel and starts with a placeholder command.
Name each trigger for its microphone and replace the placeholder with the camera angle or macro it should fire.
Calibrate each mic, quiet first and then talking, and test every microphone before you turn on automatic switching.
Livewire+ AES67 questions
Can VRA take the microphone audio straight from Livewire? +
Not on its own. The LWRP connection carries logic, not audio. The microphone channels need an AES67 receiver on the Audio Manager machine, like a RAVENNA, Merging or Digigram driver, before VRA can switch cameras from them.
Which AES67 interfaces does VRA recognise? +
RAVENNA Receive, RAVENNA ASIO, Merging Audio Device and the Digigram ALP-AES67. Any other AES67 receiver that shows up as an input device can be mapped by hand.
Does VRA mix or route the AES67 audio? +
No. Your console and audio network keep the mixing and routing. Audio Manager only reads the levels of the input channels to see which microphone is open.
Can I map the channels by hand? +
Yes. Recognition is a shortcut. Audio Manager can use any input device it can open, and you can map each channel yourself.

About Livewire+ AES67.
Livewire+ carries the studio's audio as AES67 and its logic, like a mic switched on or a button pressed, over the Livewire Routing Protocol. VRA uses both, through two separate connections. The microphone channels reach Audio Manager through an AES67 driver such as RAVENNA, Merging or the Digigram ALP-AES67, and each channel becomes a camera trigger. The Livewire GPIO connection reads GPI states over LWRP for macros and automations, but it carries no audio.
VRA does not mix or route the audio. Your Livewire system keeps doing that.
What you can do with this connection
Automated camera switching for radio
Switch cameras from microphone activity and prepare PTZ shots off air.

Livewire Routing Protocol
Use Livewire GPIO in your visual radio studio. VRA reads GPI states over LWRP to fire camera, graphics and macro actions, and you switch GPO ports by hand.
RAVENNA
RAVENNA Receive arrives as numbered stereo pairs and RAVENNA ASIO as one device. VRA recognises both and turns each mic into a camera switching trigger.
