  • Robust Headphone Amplifier Suitable For Outside Broadcast
  • PoE Powered (No DC option)
  • Dante/ AES67 Network Audio Inputs
  • 2 Balanced Analogue Outputs as well as Headphone Out
  • Suitable For Low or High Impedance Headphones
  • Use with Mono Earpieces or Stereo Headphones

Description

Virgil OB receives 2 x audio circuits from a Dante / AES67 network and routes one to the left and the other to the right channel of the headphone amplifier. A front panel volume control allows the user to adjust the output volume of the headphones. The 2 incoming audio circuits are also presented on a pair of balanced analogue audio XLRs on the rear of the unit. A switch on the side of the unit sets these 2 outputs to be post or pre fade of the front panel level control.

The Virgil OB is housed in a robust but lightweight aluminium casing that has been proven to withstand the rigours of life on the road. It also features a hardwearing beltclip allowing the unit to be quickly and securely attached to both people and infrastructure. As well as being suitable for low & high impedance headphones our unique headphone amplifier circuit can be connected to both stereo headphones & mono earpieces, making the Virgil OB suitable for driving television presenters ear pieces.

The USB port is for firmware upgrades only and should not be used for power.
