Description
High Definition Microphones™
for Fixed Installations
The Earthworks IM Series™ High Definition Microphones™ provide astounding audio quality for fixed installations. The IM Series™ can be custom mounted in a ceiling, wall or table and will provide the ultimate in sound quality, flexibility and ease of installation. The IM microphone’s uniquely designed small head and flexible mini-gooseneck allow it to be easily and precisely positioned. The IM Series™ near-perfect polar response will not beam or spotlight and will provide very high intelligibility. The frequency response of both the cardioid or hypercardioid at 90 degrees off-axis is within 2dB of the on-axis response (over its operating frequency range). This overall uniform frequency response of the hypercardioid is at least 5dB down at 90 degrees off-axis. This exceptional polar response allows the use of fewer microphones, while obtaining higher intelligibility and more gain before feedback.
Near-Perfect Polar Response
David Blackmer invented a number of new microphone technologies resulting in a totally new approach to microphone design. One such technology resulted in the creation of near-perfect polar patterns. When you look at a polar pattern of an Earthworks microphone, the mid-frequencies, high-frequencies and low-frequencies all look very close to a “textbook” polar pattern. In practice this means the polar response of an Earthworks microphone is extremely uniform over its operating frequency range; the frequency response at 90 degrees off-axis is very close to the on-axis response. This uniform polar response results in less phase problems and much higher intelligibility at the sides of the microphone.
IM Series™ Installation Microphones
The IM Series™ provides a low profile, pristine sounding microphone solution for permanent installations. Featuring a flat frequency response and patented polar technology, orators will maintain the same intelligibility throughout the room without a reduction of sound level or loss of high frequencies, while obtaining more gain before feedback. The IM Series™ installation microphones provide a 30Hz to 30kHz frequency response, near-perfect polar response with pristine audio in an attractive low-profile package with options of 3, 6, 10 or 12 inch mini-goosenecks in black, white or silver.
