The V3R is a converter unit with a high degree of flexibility concerning the I/O configuration. Three different card types enable to customise the card slot on the rear of the device for the conversion of analogue signals – 8 microphone inputs, 8 line inputs or 8 line outputs – to AES/EBU. The V3R is especially designed for rack mounted applications and permanent installation. All cards are equipped with Euroblock connectors. These common installation interfaces provide a simple and cost-efficient connection to other audio equipment.

Variations include:
  • V3R-8MI
  • V3R-8LI
  • V3R-8LO
