Audix OM11 Datasheet

OM11

OM11

OVERVIEW

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.

Dynamic Vocal Microphone

Roadworthy construction includes a two stage machined brass body, durable black

e-coat finish, dent resistent steel mesh grill and gold plated XLR connector.

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.

OPERATION AND MAINTENANCE

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.

Lo

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.
