Convention Paper

The Dynamic Vibration Absorber Principle Applied to a High Quality Phonograph Pickup

Authors: Groh, Allen R.

AES Convention 55 · Paper 1138 · October 1976

Abstract

Recent developments in phonograph disc recording have placed increased demands on the playback transducer. Both dynamic range and bandwidth have been extended, particularly on discrete four channel records. The dynamic vibration absorber principle is studied as a means of extending transducer bandwidth without compromising other parameters. An application of the vibration absorber is developed for use in a top quality magnetic phone pickup that provides high performance through almost five decades of frequency.
