Higher SPL “Big Brother” to the A-51, this upgrade of the Original A-51s (Model “S”) offers Improved Reliability, Improved Head-Room - A Broad-Brushstroke Multi-Application Mic!! Ray Charles had 6 Original “Model S” on Genius Loves Company CD.


  • The Mic
  • Piano-Black Wooden Jewel Case
  • Heavy-Duty All-Metal Ring-Mount


“From Nora Jones Viola parts to James Taylor Guitar parts, we were amazed at how many uses we had for the ADK “S” microphone! We had twenty-two ADK Mics on Genius CD.” 
- Terry Howard - Multiple Grammy® Winner – Ray Charles, Gladys Knight, Willie Nelson.

S is for SPL! Vocals, Choirs, Acoustic Guitar, Fretted Instruments (Banjo, Mandolin, Dobro, etc.), Reeds and Woodwinds. Plus: Drums – Especially Floor Toms, Drum Overheads; Electric Guitar and Bass, All Percussion Instruments, Piano. In short, the "S" will do anything the A-51 does PLUS it is Designed for HIGH SPL MULTI-Applications.  Megadeth, Ambrosia – Even Westlake Audio– use the "S" Series for Floor Toms. Megadeth also used them on  Floor Toms and Bass Cabinets! YET: A-51s were also used to track the Reed and Woodwind Section of the Seattle Symphony for a Disney Feature Film.  Think of it this way: The Model S is SUPER-VERSATILE: A ‘Swiss-Army’ Mic!!!
