SHURE KSM44A/SL – Large Dual-Diaphragm Microphone 20Hx to 20kHz

KSM44A Multi-Pattern Dual Diaphragm Microphone Premium microphone with three polar pattern options (cardioid, omnidirectional, bidirectional).

Features

• Prethos® Advanced Preamplifier Technology: Class A, discrete, transformerless preamplifier provides  transparency, extremely fast transient response and no crossover distortion. Minimizes harmonic and intermodulation distortions.  
• Groundbreaking specifications: 4dB of self-noise and max SPL of 131 dB for a total dynamic range of 127 dB – an increase of 7 dB that defines the new standard for cleanly nuanced audio capture
• Multiple polar patterns–cardioid, omnidirectional and bidirectional–for maximum flexibility in a wide variety of recording applications
• Dual 1 inch, externally biased, ultra-thin, 2.5 μm, 24 Karat gold-layered, low mass diaphragms provide superior frequency response
• Premium electronic components and gold-plated internal and external connectors
• Subsonic filter eliminates rumble from mechanical vibration below 17 Hz.
• Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
• 3-position switchable low-frequency filter helps reduce unwanted stand vibration noise or counteract proximity effect
• Integrated three-stage "pop” protection grille reduces plosives and other breath noise

K2 - ?It cant be done?? Precision Variable Pattern Dual 1? Condenser Valve Microphone.
 
The R?DE K2 is the result of designing and building 1000?s of valve microphones. The
K2?s HF-1 capsule is the pinnacle of transducer technology. The sound quality combines
modern high-end specifications with the character and subtleties of the legendary 50?s mics.
Infinitely variable control of the K2?s polar patterns provides the freedom and flexibility to
excel in any recording situation. The K2 is another example of R?DE?s commitment to
building quality studio microphones to meet the exacting standards demanded by today?s
professionals.At the 2004 Frankfurt Music Messa, 56 of the most prestgious music industry
magazines voted the K2 the ?Best Studio Microphone of 2004?.

The CK-7 houses a 35mm gold-sputtered thin Mylar capsule. The CK-7 uses high grade Polystyrene and Metalized Polypropylene capacitors in the audio path. This represents a commitment to quality, as these normally are the type of "upgrade" components that are implemented by microphone modders/hot-rodders! Any studio can proudly offer the CK-7 as a vocal mic or utility condenser due to its versatility...It exudes class visually as well as sonically.

Manufactured using the finest materials yielding a very solid feel, superb structural integrity and rugged reliability. The versatile CK-7 mic is able to produce professional results with a clean sonic character. The included Custom Retro Shockmount is superb in allowing a precise positioning of the mic while inhibiting the transfer of unwanted vibrations up into the mic. This isolation allows for superior professional results. The 3 patterns allow the CK-7 to be used in a variety of situations.

The cardioid pattern is generally best used on vocals and single instruments. The omni mode works well in incorporating some room sound into the track. The figure 8 pattern allows 2 vocalists to use the mic at the same time from opposite sides. The CK-7 has separate -10 dB pad & 80 Hz LF roll off switches....The -10dB attenuation switch can be engaged when miking very high SPL sources to keep from overloading the electronics. The 80Hz high-pass filter switch can be engaged to reduce rumble and to keep unwanted low frequencies from "muddying up" the track.

Applications.

studio vocals, acoustic guitar, mandolin, drum overheads, piano, room mic
