dAV Transmission & Intercom

digital transmission of analog A/V signals dAV
mk messtechnik dAV Series Digital Transmission

The dAV series includes not only the digital, optical transmission of camera signals (dAV-C), it can also transmit analog audio and/or video signals uni- or bidirectionally or it can be used as an intercom.

Depending on the application, the receiver of this kind of transmission can be integrated in the camera receiver (dAV-R).

Fields of application are e.g. the accoustical monitoring of an engine speed or surveillance of an audio or video system in immunity tests. The main unit dAV is thus equiped with different options. The dimensions of the housing depends on the options chosen.

Unidirectional transmission of audio and video signals: dAV-uav
Available options:
dAV option –a: unidir. dig. audio transmission of stereo signals; 3dB: 20Hz-18kHz
dAV option –v: unidir. dig. video transmission of analog video signals NTSC/PAL
dAV option –l: integrated loudspeaker, mono dAV option –m: integrated microphone, mono
dAV option -i: intercom (each device consists of a loudspeaker and a microphone)

A typical configuration is the unidirectional transmission of audio and video signals with the version dAV option –a and dAV option –v. The resulting transmitter system is called dAV-uav (see picture). Please contact us in order to get a customized offer.

The dAV-TRX system is used for the bidirectional optical transmission of AV signals at EMC tests (intercom). The dAV-TRX transceivers have an integrated microphone, a connector for an external microphone, for line IN and OUT (stereo), for video IN and OUT, and for an external (passive) loudspeaker (optional).

Fields of application are the acoustic (and optional optical) monitoring of A/V – devices, engines or radios and the use as an intercom system for absorber lined chambers. The device can stay in the chamber during the tests.
