dAV-TRX matrix
The system is suited for the undisturbed isolated transmission of audio signals in surroundings with high demands on electromagnetic compatibility.
After connecting all dAV-TRX mobile and table top devices with the dAV-TRX-Matrix using optical fibers, the dAV-TRX devices can communicate with each other.
Several stations can be connected to the matrix intercom system.
- Audio Communication in groups:
One or more groups can be created. Each device can be in either no or one group. All dAV-TRX devices within the same group can talk to each other. Only one dAV-TRX device can speak at a time, while the others in the group can only listen (half duplex).
- Broadcast function:
The broadcast function allows you to communicate with all active stations.
- Adjustable Volume for the microphone and speaker
The microphone and speaker volumes can be adjusted independently to suit your applications.
- “Permanent On” mode:
The "permanent on" operation mode enables hands-free talking. Any ongoing transmission can be interrupted by another dAV-TRX device, but it resumes when the other dAV-TRX device stops its transmitting.
The mobile dAV-TRX matrix side has an internal microphone, a built-in loudspeaker and a speak switch (see photo).
The counterpart in 19" housing is powered by an external power supply and is euqipped with an XLR connector for a removable gooseneck mic.
