Vaddio EasyUSB Audio Bridge connects pro audio kit to PC applications19 March 2014
Vaddio is bringing together the worlds of professional and PC-based audio with the launch of EasyUSB Audio Bridge. Existing meeting room audio equipment can now be used with any unified communications soft client, including Microsoft Lync, Cisco Jabber and Google+.
Equipped with both balanced and unbalanced audio inputs and outputs, the Audio Bridge integrates with any audio I/O devices that require USB integration, such as external audio mixers, wireless microphones, amplifiers and powered loudspeakers.
Professional audio equipment connects to the Audio Bridge with balanced line level inputs/outputs on a 3-pin Euro Terminal block. Unbalanced audio inputs/outputs are supported with RCA connectors.
“The Audio Bridge converts the analogue audio input/output signal into a USB stream detected by the computer as a USB sound input/output device,” explained Vaddio CEO Rob Sheeley. “As a result, the PC can control both input gain and output volume from the application (Cisco Jabber, Google+, etc.) and OS control panel. There is also independent USB and analogue audio gain control. The gain structures can be configured between the pro audio equipment without being impacted by PC volume controls.”
Additional functionality includes System Gain Lock for controlling audio gain on the PC to eliminate interference with the external audio mixer’s automatic gain control. Two conferencing mixing mode configurations are available, for connecting to professional audio conferencing mixers with and without internal echo cancellation.
