|Time: 1:30 PM
||***NOTE THE TIME!***
Featured Guest: Klaus Peter
Topic: Preamp and Amp designs, Live Recording
1) Klaus has designed a unique microphone preamplifier that differs mainly in its high current supply. He uses similar
design techniques in a general purpose preamp with unusually low noise and distortion. He will display details of the design on a transparency/overhead.
2) He has designed a novel amplifier circuit and plans to apply for a patent. His unit has excellent specifications
and is inexpensive to build.
3) He considers himself an amateur recording engineer; however, he has produced at least one CD that is outstanding.
Alvin Foster uses it for loudspeaker testing etc. He plans to discuss how and why he uses certain microphones and their respective positions in the
recording venue. He will bring along a disc for us to hear at the Sunday meeting.
Klaus has over 25 years of design experience in consumer and industrial electronics. At HH Scott and Syma International, besides
some regular amplifiers and receivers, he designed the first consumer Digital FM Tuner (digital frequency synthesis) in the market. When he left, he
had been promoted to Chief Engineer. He held the position of Engineering Manager at Digital Equipment Corporation in the data storage division. He received
an EE from University of Ottawa Canada.
His newest company, Ripos, produces exhaust mufflers that render diesel powered motors (cars, generators, etc) environmentally friendly.
