Produced in the mid-90s primarily for concert rock touring bands with exceptionally loud stage volumes, the OM7 has earned reputation in the pro sound industry as being the "ultimate gain before feedback" microphone.

The OM7, which is designed with an unconventionally low output level (8-10 dB lower than typical dynamic mics), has a built-in pad which allows for the natural full audio range of the capsule to be utilized.

On a mixing console with proper head room, the OM7 will handle sound pressure levels in excess of 140 dB without distortion. The performance characteristics of the OM7 allow it to be placed in close proximity to drums and guitar cabs, with minimal bleed, and tremendous resistance to feedback.

The OM7 was similar to the OM5 and also added more rejection and a built in pad. This is the type of mic to use when you really like to be on top of it at all times. Bands like Blink 182, Tool, Red Hot Chilli Peppers all use this mic.
Hear the difference yourself: Normal SM58 - OM5 ...about 1 inch away from the front of each mic Proximity SM58 - OM5...lips touching the mic Rejection SM58 - OM5...150 degrees off the front axis, simulating a monitor noise entering the mic.
