Shure KSM109 End-Address Condenser Microphone

KSM109 End-Address Condenser Microphone description:

The Shure KSM109 is an end-address condenser microphone with a cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM109 delivers a clear reproduction of the origninal sound source. Its extended frequency response makes it ideal for recording musical instruments.

Features:

• Cardioid polar pattern to reduce the pickup of unwanted sounds
• Ultra-thin, 2.5 um, 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
• Two-position switchable pad (0 dB and 15 dB) for handling extremely high sound pressure levels (SPLs)
• Low self-noise
• Superior common mode rejection and suppression of RFI (radio frequency interference)
• Great for close miking of acoustic instruments such as piano, guitar, violins, drums, and percussion, Overhead miking of drums and percussion instruments, Electric guitar amplifiers, Brass and woodwind instruments, Orchestras, choirs, and wind ensembles
• Vinyl Pouch, Windscreen and Microphone Clip included with this microphone
