AVDT-BOB – Compact Dante breakout box

The AVDT-BOB is a compact Dante break out box with embedded Digital Signal Processing.
The AVDT-BOB has state-of-the-art analog microphone preamplifiers for a very high audio dynamic and quality over Dante at a very contained price:

  • 4x Dante input channels and 4x Dante output channels with Dante routing
  • 2x or 4x Mic/Line balanced inputs with independent phantom +48V
  • 2x or 4x Analog balanced outputs
  • 60dB gain range by 3dB step with Input Noise (EIN) as low as -125dBu
  • Stereo AES/EBU Input and Output on Euroblock (-ADE- Versions) or on SUBD25 (-ADX- Versions)
  • 4x Analog GPIOs for remote control on Euroblock (-ADE- Versions) or on SUBD25 (-ADX- Versions)

The AVDT-BOB has a DSP to process and mix audio signal at the source and at the output. The AVDT-BOB features a dual core ARM processor associated with a large amount of flash memory for a universal and multiplatform remote control over IP (iOS, Android, Windows, Mac OS, Linux). They provide to the AVDT-BOB a powerful processing with an efficient, easy and smart remote control:

  • Smart embedded DSP for advanced internal audio mixing and effect processing
  • 4 independent mixers of the 6x to 8x inputs
  • 8 equalizations and 8 limiters compressors
  • Build-in dual ARM RISC processor with Web 2.0 HTML5 interface
  • Direct remote without any installation via Mac OSX, Windows, and Linux computer or via iPad, iPhone or Tablet, Smartphone

The AVDT-BOB integrates an internal 5 ports Gigabit switch to ease the cabling, to increase the throughputs and to reduce  latency. It allows to Daisy-Chain the AVDT-BOB together with other Dante devices without necessarily requesting any external switch devices. The AVDT-BOB embeds an internal PoE module connected to its main Ethernet port for powering and communicate with a single Ethernet cable:

  • 2x RJ45 connector (-AE- Versions) or 1x Neutrik EtherCon with 2x SFP cage for Optical connection (-AS- Versions)
  • Integrated Gigabit switch for easy daisy-chaining of multi devices

The AVDT-BOB box is made of a very lightweight, robust and smart extruded aluminum. This box was thought to bring to the user many mounting options, thanks to side rails that allows to attach any type of fixations. The AVDT-BOB is delivered with side ears that can be mounted in any positions. An optional mounting kit allow to interconnect up to 3x AVDT-BOB devices and so to build a Dante unit with for example 12x Mic/Line inputs and 12 analog outputs in the only space of a 1U 19″ rack.
