PLACE: Zoom/Virtual Video Conference
FEATURED GUEST: Peter Ledermann, President/Chief Engineer

TOPIC: Fixed Coil vs. Moving Coil Cartridges, Loudspeakers (Bozak), Amplifiers+++

Peter Ledermann has a long history in audio that stems from his very early years, initiating from a deep fascination with science, nature, and music. He opened the Soundsmith repair center for high end audio in 1969 at Audio Experts in White Plains NY, and taught audio engineering and service as he has done continuously for the past 47 years.

In Peter’s words: In 1973 he was offered a position with RAM Audio in Danbury Connecticut. Peter was responsible for assisting with engineering and oversaw all of manufacturing and training production personnel in manufacturing two high end power amplifiers as well as two preamplifier designs, and a Strain Gauge cartridge/preamp system.

In 1976 Peter became Director of Engineering at the Bozak Corporation in Norwalk Connecticut. He re-engineered an analog rear channel delay system, all of Bozak’s complete line of varied electronics, and developed a new aluminum cone 6” wideband driver for his new miniature Bozak speaker model MB-80.

In 1991, Peter left IBM to pursue the Soundsmith effort full time. He continued to mentor and teach audio engineering through service, designed and developed his own line of speakers, amplifiers, preamplifiers and continued to develop new ideas for cartridges.

In addition to being an artist and world-renowned audio engineer, Ledermann is also a published poet., here: www.sound-smith.com/memoriam
