Digigram ALP-AES67 mics as camera switching triggers
A Digigram ALP-AES67 card puts your AES67 and RAVENNA microphones on the Audio Manager machine. VRA recognises the card's channel pairs by name and turns every microphone into a camera trigger.
What VRA does with Digigram ALP-AES67.
Recognised by name
VRA recognises WDM channel pairs whose device name contains DIGIGRAM ALP-AES67, and converts the detected pairs into microphone triggers together.
Pairs sorted, then split
The card's driver lists its receive channels as stereo pairs. VRA orders them by device and by number, then splits them into single channels so each microphone gets its own trigger.
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.
Recognised as WDM only
VRA has no ASIO pattern for the ALP-AES67. Recognition works on the WDM pairs; an ASIO view of the card has to be mapped by hand.
How to set it up.
Requirements
- Audio Manager on a Windows or macOS machine that can open the Digigram ALP-AES67 device.
- The Digigram ALP-AES67 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 Digigram ALP-AES67 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.
Digigram ALP-AES67 questions
Does VRA recognise other Digigram cards? +
Only device names containing DIGIGRAM ALP-AES67 are recognised. Another Digigram card works like any other input: map its channels by hand.
Does VRA mix or route the Digigram ALP-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.

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.
