Shure SM53 Dynamic Cardioid Microphone
The Models SM53 is a rugged dynamic cardioid microphone expressly designed for professional applications requiring the ultimate in sound quality and control. SM53 is designed for both stand and hand-held use. No special precautions are required to avoid obstruction of the rear entries, since normal operation is assured even with only one of the small rear entry holes open.
Features:
- Broad, smooth frequency response: provides clean, natural reproduction of both voice and music.
- Cardioid directional pattern: the optimum pattern for comfortably wide front working area with excellent side and rear rejection.
- Uniform, symmetrical polar pattern: off-axis rejection is uniform with frequency and completely symmetrical about the axis to prevent sound coloration due to off-axis pickup and to provide maximum control of unwanted sound.
- Integral acoustic “pop” filter on the SM54 virtually eliminates problems of explosive speech and breath sounds.
- Minimal proximity effect: permits the same well balanced sound from close talking to distant pickup.
- Mechanical noise isolation: cartridge shockmounted to minimize stand and handling noise.
- Bass rolloff switch: provides a gradual low frequency rolloff in applications where an overall rising response characteristic is advantageous.
- Extremely low hum sensitivity: permits use in extreme hum fields.
- Rugged construction: assures dependable operation with unchanging performance.
