OVERVIEW Virgil was the Roman poet who guided Dante through Hell and Purgatory, the Glensound Virgil 1 is a clever little headphone amplifier for providing crystal clear audio into studio & broadcast headphones. Packaged in a small & robust format and designed to be permanently mounted in studios wherever a headphone circuit is required, the Virgil 1 provides a simple interface between Dante network audio systems and users headphones.
PANEL LAYOUT & FUNCTIONS 1. Volume Control 2. Power ON LED 3. Headphone Connections 1. Volume Controls This potentiometer equally adjusts the headphone volume of the two input circuits being received from the Dante network. 2. Power ON LED This bright blue LED indicates that the Virgil 1 is receiving power from the network and is working correctly. 3. Headphone Connectors These 2 headphone jacks are wired in parallel with each other.
4. USB Socket 5. Network Connection 4. USB Socket This micro USB socket has a dual purpose. It can be used to either power the Virgil 1 from a suitable standard USB power source and it also provides a connection for a computer to upload new firmware into the unit if ever advised to by our technical department. 5. Network Connection This is a standard network RJ45 connector. Connect this to your DanteTM network to provide the audio source for the Virgil 1.
CONNECTING THE VIRGIL 1 TO A DANTE NETWORK The Virgil 1 is a network audio device utilizing the reliable and versatile Dante audio over IP protocol. Dante is a proprietary system (although very widely used) the originators of which are Audinate. The information below is only meant as a very basic guide. Full details of the power of Dante network audio and instructions for using it can be found at www.audinate.com Two Audio Inputs There are just 2 audio inputs to the Virgil 1 from the Dante network.
Running Dante Controller At the time of writing this manual, Dante Controller looks as per the screenshot below: The Virgil will have been named at the factory during test to allow them to be identified by the Dante controller. The format used for the factory name is: ‘Virgil-serial-XXX-YYY’. ‘XXX’ will be the units 3 digit serial number, and ‘YYY’ will be the Vita’s MAC address.
HEADPHONE OUTPUT ATTENUATION By default the Virgil 1’s front panel headphone volume potentiometer is set to allow an output level off between -20 and +10dB (measured into 600 Ohms). This means that incoming audio signals cannot be completely turned off (which many broadcasters find useful to stop ‘talent’ turning important audio information off and missing vital cues). It is possible to alter the range of the volume potentiometer to allow the headphone output to become fully attenuated (off).
