The KSM44/SL is a multiple pattern (cardioid, omnidirectional, bidirectional), externally biased, dual large diaphragm condenser microphone with extremely low self-noise (7dB). Developed to meet the needs of studio recording musicians, the warm, rich sound of the KSM44 delivers exceptional performance, tailored to deliver vivid reproduction of voice for the most critical recordings. The KSM44 also offers great flexibility in a variety of recording applications, working well on acoustic and amplified instruments, as its capacity for managing high SPLs accommodates loud sound sources such as drums and guitar amplifiers.

Dual 1-inch, externally biased, ultra-thin, 2.5 micron, 24-karat gold-layered, low mass, Mylar ^® diaphragms provide superior transient response

Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response and no crossover distortion; minimizes harmonic and intermodulation distortions

Full-range frequency response (20 Hz - 20 KHz) for an extremely accurate reproduction of voice and instruments

Extremely low self noise (7 dBA) for critical studio vocal recording

Premium electronic components and gold-plated internal and external connectors

Subsonic filter eliminates rumble from mechanical vibration below 17 Hz

15 dB attenuation switch for handling high input SPL sound sources

3-position switchable low-frequency filter virtually eliminates unwanted background noise and controls proximity effect

Applications
The KSM44/SL is designed as a premium vocal microphone for studio recording. Microphone use, however, is a matter of personal taste. Here is a non-exhaustive list of common applications:

Vocals -- solo, background, voice-over

Acoustic instruments -- such as piano, guitar, drums, percussion, strings

Wind instruments -- brass and woodwind

Low frequency instruments -- such as double bass, electric bass, kick drum

Overhead miking -- drums or percussion

Ensembles -- choral or orchestral Room ambiance pick-up -- guitar amplifier or drums

Both the acoustic environment and microphone placement have significant effects on the sound obtained when miking any sound source. We encourage users to experiment with these variables to achieve the best overall sound.
