USER MANUAL OM11 Audix

The OM11 is a re-issue of the original OM1, a hand-made microphone first issued in 1985. Designed, assembled, machined and tested by Audix in the USA, the OM11 is a dynamic vocal microphone used for a wide variety of live, studio, and broadcast applications. The OM11 is known for its sharp, crisp vocal sound, resistance to feedback and ability to handle high sound pressure levels without distortion.

The OM11 is characterized with a tight and uniformly controlled hypercardioid polar pattern which helps to isolate the vocals from the rest of the instruments on stage. With a wide frequency range of 50 Hz - 18 kHz, the OM11 employs a VLM ^™ (Very Low Mass) diaphragm for a very clean and natural sound with exceptional transient response.

The OM11 response is tailored to cut through the mix, providing presence and articulation to the vocals even at very high stage volumes. In addition to having extremely low handling noise, the OM11 is well balanced, comfortable to hold, durable and manufactured with very high standards and tight tolerances.

Roadworthy construction includes a two stage machined brass body, durable black e-coat finish, dent resistant steel mesh grill and gold plated XLR connector.

POLAR PATTERNS

ARCHITECT AND ENGINEER SPECIFICATIONS

The microphone shall be of the dynamic type and the polar pattern of the microphone shall be hypercardioid. The nominal output impedance shall be equal to 200 ohms at 1 kHz. The microphone shall have a sensitivity of 1.9 mV/Pa at 1 kHz and a sound pressure level ≥ 140 dB. The microphone body shall be machined of brass and the grill cap shall be steel wire mesh. The overall dimensions shall be 21.7 mm in diameter at the base, 54 mm in diameter at the widest point on the grill and 179 mm in length.

The OM11 is a low impedance microphone and should be plugged into the "mic level" input of your console, mixer, or recording device. Please note that your microphone does not require phantom power and will not be affected in any way by phantom power should it be running simultaneously while the microphone is in operation. Avoid plugging or unplugging the microphone from a PA system unless the channel is muted or the volume of the system turned down. Failure to do so may result in a loud "popping" noise which could seriously damage the speakers in the PA system.

The OM11 is manufactured to exacting specs with roadworthy construction. However, the capsule is highly sensitive and should be handled with care. Avoid extreme temperatures and be sure to store your microphone in the pouch provided when not in use. Moisture of any kind can adversely effect the sound and performance of your microphone.

USER TIPS

The OM11 has a tight pick-up pattern in order to help eliminate sound from other instruments on stage from "bleeding" into the microphone. For best results, it is important to sing directly into the mic at close proximity (within 2 inches).

When using floor monitors, position the microphone so that it is parallel to the floor. When using multiple microphones on a live performance stage, allow a distance of 2-3 feet between mics to avoid phase issues.
