Description
dAV Fiber-optic Audio Link for Reliable Signal Transmission
The dAV Fiber-optic Audio Link and Intercoms provide a robust solution for transmitting analog audio and video signals digitally over fiber optics. Designed for high-performance environments, these systems ensure noise-free, stable communication in demanding testing applications. With flexible configurations, the dAV series supports both unidirectional and bidirectional transmission, making it ideal for EMC laboratories and monitoring setups.
Flexible Transmission Options for Audio and Video
The system can be configured based on application needs:
- dAV option –a: Unidirectional digital transmission of stereo audio signals (20 Hz–18 kHz).
- dAV option –b: Bidirectional digital transmission of audio and video signals.
- dAV option –v: Unidirectional digital video transmission (NTSC/PAL).
A common setup includes unidirectional audio transmission with switchable options, resulting in the versatile dAV-uv-switch model. This makes the system adaptable to different test environments and requirements.
Intercom Solution for EMC Test Chambers
The dAV-TRX Intercom system extends the functionality of the dAV series by enabling bidirectional communication. Equipped with an integrated microphone, external microphone input, and optional passive loudspeaker output, it is perfectly suited for absorber-lined chambers where clear communication is critical. With its compact design, the device can remain inside the chamber during tests without interference, providing seamless monitoring of audio and video devices, engines, and radios.
Applications Across Multiple Industries
Engineered in collaboration with MK-Messtechnik GmbH, the dAV Fiber-optic Audio Link and Intercoms meet the needs of automotive, aerospace, military, RF, and space industries. Whether it is monitoring engine acoustics, verifying device immunity, or maintaining communication during EMC tests, this solution delivers consistent performance while meeting MIL-STD-461 compliance.
