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 SPLs 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 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 tight tolerances.
