D 3700/D 3700 S
Tripower Dynamic Microphone
Description
The AKG Model D 3700 is a rugged dynamic
hypercardioid microphone intended for on-stage instrumental
and vocal pickup. Its hypercardioid pattern is uniform with
frequency, and response has been boosted at mid and high
frequencies for crisp instrumental pickup and improved
speech intelligibility. The microphone capsule is shock
mounted with an easily removable wire mesh grille. The
smooth triangular shape of the microphone is easier to hold
than normal circular cross-section designs and is stable
when the microphone is placed on a surface. The light-
weight body is die cast zinc alloy and has a dark matte finish
for minimum reflection and glare. The D 3700 S shall have a
recessed, noiseless on-off switch.
Features
• Response tailored for instrumental
and vocal on-stage performance
• Accurate hypercardioid pattern for
added immunity to feedback
• High sensitivity (2.5 mV/Pa)
resulting from use of high-energy
neodymium-iron-boron magnet
• Light-weight die cast metal body
with dark matte finish
• Replaceable grille assembly
