OM3

OM3

OVERVIEW

Designed, assembled and tested by Audix in the USA, the OM3 is a dynamic vocal

microphone used for a wide variety of live, studio, and broadcast applications. The

OM3 provides clear and accurate sound reproduction, resistance to feedback and the

ability to handle very high SPL (Sound Pressure Levels) without distortion.

The OM3 is designed 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 OM3 employs a VLM™(Very Low

Mass) diaphragm for natural sound with exceptional transient response.

The OM3 is naturally attenuated in the lower mid-bass frequencies in order to reduce

boominess and handling noise. This, in conjuction with an extremely articulate mid-

range, makes the OM3 an excellent choice for PA systems of all sizes. The OM3 is well

balanced, comfortable to hold, durable, and designed with high standards and tight

tolerances.

The OM3 is manufactured with a precision die cast zinc alloy body, durable black

E-coat finish, dent resistant 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 290 ohms at 1 kHz. The microphone shall have a sensitivity of 1.6 mV /

Pa at 1 kHz and a sound pressure level ≥144 dB. The microphone body shall be

of zinc alloy and the grill cap shall be steel wire mesh. The overall dimensions

shall be 23 mm in diameter at the base, 53 mm in diameter at the widest point

on the grill and 176 mm in length.

OPERATION AND MAINTENANCE

The OM3 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 the 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.

POLAR PATTERNS

Lo

The OM3 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 OM3 has a very 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.
