Cardioid Condenser Microphone with Windscreen & Case
Cardioid Condenser Microphone with Windscreen & Case
Cardioid Condenser Microphone with Windscreen & Case
Features:
A highly consistent cardioid polar pattern
Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar® diaphragm for superior transient response
Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion
Premium electronic components, including gold-plated internal and external connectors
Subsonic filter eliminates low frequency rumble (less than 17 Hz) caused by mechanical vibration
Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
Three-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs)
Three-position switchable low-frequency filter reduces background noise and counteracts proximity effect
Performance Characteristics
Extended frequency response
Low self noise
Exceptional reproduction of low-frequency sounds
Can withstand high sound pressure levels (SPL)
High output level
No crossover distortion
Uniform polar response
Superior common mode rejection and suppression of radio frequency interference
