OVERVIEW
Virgil was the Roman poet who guided Dante through Hell and Purgatory, the
Glensound Virgil OB is a clever little headphone amplifier for providing crystal clear
audio into studio & broadcast headphones.
Packaged in a small & robust format and designed for outside broadcast & theatre
applications wherever a headphone circuit or analogue output is required, the Virgil
provides a simple interface between Dante® / AES67 network audio systems and
users headphones or other analogue audio equipment
The Virgil OB encompasses our unique headphone amplifier circuit which
automatically provides the correct output level to match the impedance of the
attached headphones (to produce the same volume high impedance headphones
require a much greater output level than low impedance).
The audio inputs of the Virgil OB are Dante®/ AES67 compliant network audio
circuits. Dante® network audio is a common protocol for distributing high quality
linear audio over standard IP networks and it is widely used by many audio
equipment manufacturers. The Glensound Virgil OB Dante® audio interface will be
compatible with any other manufacturers’Dante® audio interface.
Network audio routing is managed by the Dante® Controller software. Further
details of Dante network audio, and the Dante Controller software can be found at

being received from the Dante network.
It also can adjust the output volume of the balanced line level XLR outputs on the
rear panel.
3. Headphone Connectors
These 2 headphone jacks are wired in parallel with each other. They are both 3 pole
TRS (Tip Ring Sleeve) but both can accommodate 2 pole ‘mono’ jacks.
