AKG SOUNDS BETTER

D 40

The D 40 with its solid all-metal body will
stand up to the hardships of night-after-night
on stage use “with a smile”.

The Varimotion™ diaphragm deep-drawing
process allows the diaphragm itself to be
fine-tuned with no need for tuning resonators,
leading to a quantum leap in audio performance.
The transducer is protected by a sturdy wire-mesh
cap and takes extremely high sound pressure
levels with ease. An integrated stand adapter
and standard H 440 mounting bracket for snare
drums, tom-toms, etc. make the D 40 a highly
versatile tool for use on drums, percussions,
wind instruments, and guitar amps.

■

Dynamic microphone designed for drums
and percussions, wind instruments,
and guitar amps

■

Patented AKG Varimotion™ diaphragm

■

Custom built capsule mounting

■
