D 770
Dynamic Microphone
Description
The AKG Model D 770 is a rugged dynamic cardioid microphone intended for on-stage vocal and instrumental pickup. Its cardioid 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 has a heavy duty, dent resistant spring-steel windscreen with an integral pop filter for effective suppression of breath noise. The microphone incorporates two important AKG developments: In the “Tiefzieh” Varimotion System™ the diaphragm thickness varies from 20 microns at the edge to 40 microns at the center. This distribution of mass produces extended bass response, virtually eliminating the need for a tuning resonator. In addition, the Doubleflex™ 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 light-weight body is die cast zinc alloy and has a dark matte finish for minimum reflection and glare.
