Large Diaphragm Condenser Mic Shootout on Male Vocals

This blind Large Diaphragm Condenser Microphone shootout on Male Vocals features 4 incredible LDC mics: the Shure KSM44, Miktek C7, CharterOak E700, and the Lauten Clarion. All four mics were run through our Vintech 573 Preamp Modules and Lynx Aurora Converter. First we'll hear the mics completely dry, and then just for kicks we'll add in some traditional vocal reverb from our Bricasti M7 Reverb System. If you would like the results of the shootout or all five full length hi-res audio files to compare for yourself, shoot us an email to mics(at)soundpure.com at anytime. Additionally all of these microphones are eligible for our free Try-Before-You-Buy demo program, so if you like what you hear and would like to experience one of these mics for yourself, give us a call at anytime for more information. Huge thanks to our vocal talent Beau Buttons for this great original performance! Follow him on twitter at: www.twitter.com/beaudeas. If you have any questions about the four LDC mics used, the shootout setup, or recording gear in general - we're here to help. Thanks for watching! 919-682-552 or toll free 888-528-9703

Manufacturer's Description from Shure

The KSM44A is a premium, large-diaphragm, side-address condenser microphone with multiple polar pattern options (cardioid, omnidirectional, bidirectional).  The refined and sophisticated design of the KSM44A features an externally biased, dual 1-inch diaphragms, extensive internal pop filtering and Prethos® Advanced Preamplifier Technology for a ground-breaking threshold minimum of self-noise.  The KSM44A is the premier choice for the highest level of professional studio and stage performance.

A milestone achievement in sound reinforcement, Prethos Advanced Preamplifier Technology employs transparent internal circuitry architectures that enable unprecedented audio quality and performance.

  • 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
