Earthworks IML3-B

The Earthworks IML3-B features a 30kHz flat frequency response, uniform frequency response on or off axis, and more gain before feedback. The gooseneck allows quick and easy positioning and has a programmable touch-sensor output and programmable dual-colored LED light ring.

When CenturyLink was looking to upgrade its executive conference room at its Arlington, Va., office’s Government Contracting Division, the company turned to Audio-Video Group to design and install the system. Reliability, quality, and exceptional clarity were key requirements in the system redesign and meant replacing the table-mounted button microphones. 

With those client requirements at hand, Stephen Bon, sales development engineer at Audio-Video Group, selected the Earthworks IML3-B microphone for the install. Bon was already familiar with several of the company’s mic series, having installed them in may of his church sound system designs.

CenturyLink has several conference rooms in its facility, which can be combined and can send audio feeds to and from the different rooms. The Earthworks IML3-B microphones were installed in the executive conference room, which is where a large portion of the company’s audio conference calls are made from. In this room, there is a horseshoe shaped conference table with six Earthworks IML3-B microphones on both sides, as well as two IML3-B microphones at the end of the table, for total of 14 microphones.

Bon selected the IML Series microphones, which feature the LumiComm Touch Ring for the installation, allowing him to program the microphones with an AMX control system. 

“The Earthworks IML microphones have provided us excellent fidelity of the audio pickup that is extremely consistent, both on and off-axis, which allows them to overlap and blend well together,” Bon says. 

Bon found the polar response of the IML3-B microphones to be a great advantage over the button microphones they replaced, as well.
