Milford, NH – When a leading website optimization platform company was looking to upgrade their video conferencing rooms at their San Francisco headquarters, they turned to Audio Visual Design Group to design and install the system.
Among the requirements for the installation was superior sound from ceiling-located microphones, which also blended in with the interior design.
Aaron Obstfeld, Director of Technical Services at Audio Visual Design Group, explains the primary audio challenge with this installation: “Ceiling mics by nature are difficult to make sound good due to the distance from participants and the unintended sound they can pick up. These rooms themselves were acoustically challenging as well.”
With those challenges and client requirements in mind, Obstfeld and Project Engineer Greg Spydell selected the Earthworks IM3-W and C30/C-W microphones for the install. “The specifications and our preliminary testing led us to believe we could minimize factors such as ambient noise and acoustic reflectiveness for a better quality sound.”
The project involved 3 independent spaces, with the IM3-Ws being installed in the room with a drop-tile ceiling. The C30/C-Ws were installed in the other two rooms due to an exposed ceiling. The microphones were installed with a Biamp TesiraFORTE DSP, Labgruppen E4:2 Amplifier and Tannoy CVS6, OCV6 & Di 6Ct speakers (respectively of different rooms) for use with a video conferencing application using Vidyo HD-230 Video Conference codecs.
The IM3-W provided substantial improvements over other microphones Obstfeld had previously used for this type of application. “The audio quality was superior to other ceiling microphones we’d used for conferencing applications,” explains Obstfeld. “Improved clarity, appropriate pickup patterns and fewer issues with distance from microphone to participant were some of the key improvements with the Earthworks IM3-W microphones.”
improved sound quality, Obstfeld also notes ease of installation as a chief
benefit of the IM3-W. “Our install technicians had a very
easy time with mounting and configuration – particularly in ACT ceiling
tiles. They’ve asked that Earthworks
become our standard for ceiling microphones from an installation perspective. The quality of sound was good enough that we
