AKG Acoustics D550 User Manual

D 550

Dynamic Instrument Microphone

Description

The AKG Model D 550 is a rugged dynamic cardioid
microphone intended for all on-stage bass instrument pickup,
including bass drum, tuba, trombone, and bass guitar amps.
Its cardioid pattern is uniform with frequency, and response
has been boosted at both low and high frequencies for
effective bass instrumental pickup under typical stage
conditions. The strong housing and shock absorbing outer
grille provide protection for the transducer. A layer of inert
textile provides a very effective guard against wind and pop
noise. The microphone incorporates two important AKG
developments: In the “Teifzieh” Varimotion System

TM

the
diaphragm thickness varies from 20 microns at the edge to
40 microns at the center. In addition, the DoubleflexTM
mounting system used with the capsule assembly places the
primary resonance of the moving system to well below the
audible range, resulting in excellent isolation of handling and
cable induced noises. The microphone has an integral stand
adapter, and the light-weight body has a dark matte finish for
minimum reflection and glare.

Features

• Response tailored for bass
instrumental on-stage performance

• Frequency independent cardioid
pattern for added immunity to
feedback

• Very low susceptibility to pop and
wind noise

• High sensitivity (2.5 mV/Pa)
resulting from use of high-energy
neodymium-iron-boron magnet

• Integral stand adapter
