1. AA/IDER FRONT >VORKING ANGLE
The SM53 allows greater freedom of performer movement — tonal quality is unaffected by movement throughout the broad effective pickup area. Eliminates "holes" and "hot spots" when using multiple microphones. These valuable attributes stem from a broad, true cardioid frontal pattern at all frequencies, in all planes — freeing the user from the restrictions of overly tight angular sensitivity.
2. MORE EFFECTIVE REJECTION OF UN\VANTED SOUNDS
The SIV153 prevents sound coloration due to off-axis reflections or reverberation — and, in addition, unwanted sounds (even air conditioner rumble) are effectively controlled. These properties are achieved through the polar pattern which is singularly uniform with frequency (even at the extreme low end) and is symmetrical about its axis.
3. MECHANICAL NOISE ISOLATION
Built-in effective shock mount significantly reduces the objectionable stand, cable, and handling noises associated with many unidirectional microphones. The SM53 can be used in many applications where conventional units have proved marginal or unusable.

4. EXTRAORDINARY RUGGEDNESS
You can even drop the SIVIBS directly on its nose without damaging the microphone element — and it will maintain its excellent performance characteristics.
5. SUPERIOR HUM REJECTION
Built-in hum-rejection system reduces magnetic hum susceptibility by as much as 20 db compared to other units! Makes it far more usable in distant pickup applications and in areas with extremely high magnetic fields.
6. LESS SUSCEPTIBILITY TO "POP"
Integral "pop" filter minimizes explosive breath noise without external screening. Works well where other microphones are marginal or unusable.
7. MINIMIZED PROXIMITY EFFECT
Uniform tonal quality is maintained (without objectionable low-end build-up) regardless of whether the microphone is worked close up or from a distance.
8. FIELD SERVICEABILITY
Element (cartridge), connector, front screen, roll-off switch can all be replaced in minutes.
