  • AIR adds top-end sparkle, while FLAT reproduces your sound as it is. Try both and capture the performance the way you want.

Two switchable sound characteristics, AIR or FLAT? Record the source the way you want.

  • AIR delivers an open, sparkling character. The right choice if you need great sound without spending time on post-production.
