Description

The Earthworks IMR Series rigid center gooseneck microphones are designed for permanent installation in tabletops for conferencing and other speech applications.

Performance

When capturing every word is critical, the IMR microphones are the most reliable miking solution. Optimized for speech, the IMR microphones feature a frequency response out to 30kHz that delivers the highest level of speech intelligibility and articulation. This means less straining to understand the words being spoken due to poor audio quality, so more time can be spent understanding the message being transmitted.   

Whether speaking directly on-axis or to the sides of the microphone, the IMR microphone always reproduces the speaker’s voice with incredible clarity and intelligibility. This wider coverage also means that fewer Earthworks microphones are required to properly cover a conference room, cutting down on the number of channels of DSP, cables and other ancillary equipment required for the system. Compatible with all DSP systems that provide 24-48V phantom power, the IMR microphones can easily integrate into existing system designs or new installations.

Construction

Designed with aesthetics in mind, the IMR microphones feature a slim 0.375“ (9.5mm) gooseneck with rigid center that allows precise positioning of the microphone for optimal coverage. The gooseneck flexes on both ends, however the center is rigid, providing a more polished appearance when re-positioning the microphone. The microphone flange measures just over 1.4 inches (36.5mm) wide and 0.125 inches (3.2mm) tall, mounting flush into the tabletop or ceiling for a low profile appearance.

Options

The IMR microphones are available with a 10 or 12 inch rigid center gooseneck. Black finish.

  • Conferencing / Installed Sound

The narrow usable portion of a conventional microphone’s polar response (with full frequency response) provides only a narrow area that will pick up sounds without high frequency losses at the sides of the microphone. The figures on the left indicate how many conventional microphones it takes to cover a room (with an 8 foot ceiling) and provide the full frequency response of the microphone at the head of a six foot man, in standing position.

The figure on the right shows the much wider polar response (with full frequency response) of Earthworks directional High Definition Microphones™, requiring fewer microphones. In addition you also have more sound level before feedback, no spotlighting or highlighting, more rejection of sounds from the rear of the microphone, in addition to a vastly superior sound quality.

CX

“Each mic yields more coverage, so you need fewer of them. The first benefit of this is potentially a reduced scope for phase errors between mics. The second is that you require less cabling and DSP to connect and process inputs.”

Great consistent coverage and a clean, natural, and transparent sound as I have come to expect from the Earthworks product. It makes good audio easy.

Dan Burdett, db Media Group

They just simply work, and do so better than any other ceiling mics we’ve encountered. The biggest difference is the pickup pattern and coverage area.

Mark Templeton, Casaplex

The audio quality was superior to other ceiling microphones we’d used for conferencing applications. 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.
