ensures minimum operating cost and ultimate convenience.

RUGGED BODY

Light, convenient, compact, sturdy.

Never before had it been possible to make a microphone diaphragm whose
thickness varied along its diameter. The VARIMOTION technique tunes the
diaphragm itself to the desired resonance frequency, eliminating the need
for tuning resonators in the microphone body.

The result is a better sound than ever before.

This two-stage shock mount suppresses handling and cable noise almost
completely, so the audience will only hear the sound of your voice.
