DYNAMIC VOCAL MICROPHONE

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 is known for its clear and accurate
sound reproduction, resistance to feedback and ability to handle very
high SPL (Sound Pressure Levels) without distortion.

The OM3 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 OM3 employs a VLM™(Very Low Mass) diaphragm for a
clean and 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 conjunction 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 manufactured with high standards and tight
tolerances.

The OM3 includes a precision die cast zinc alloy body, black E-coat
nish, laser etched model and serial number, steel mesh grill,
Switchcraft® XLR connector and heavy duty nylon clip.

FREQUENCY / POLARS:

ARCHITECTS AND ENGINEERS 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 250 ohms at
1 kHz. The microphone shall have a sensitivity of 2.5 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. The
microphone shall be the Audix OM3.

OPERATION:

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 eected 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.

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 oor monitors, position the microphone so that it is parallel to the oor.
When using multiple microphones on a live performance stage, allow a distance of 2-3

feet between mics to avoid phase issues.

SERVICE AND WARRANTY:

This microphone is under warranty for a period of 5 years from
any and all manufacturing defects. Should your microphone
fail in any way, please contact the Audix Service department
at 503-682-6933. A Return Authorization number is required
before returning any products.

CARE AND MAINTENANCE:

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 aect
the sound and performance of your microphone.
