Overview:
The Fredenstein F676 Microphone Preamplifier is a valve (tube) based preamp with a fully
balanced signal path throughout. The design incorporates high quality input and output transformers
and features a zero Negative Feedback architecture. The F676 uses a Digital Signal Processor
(DSP) to control the operating points of the tubes, guarantying perfect working conditions all the
time. The final result is a preamp with a very pleasant sonic footprint, lush smooth highs without
being harsh and very detailed mids and lows. The F676 will make a difference in any studio.
The name F676 is a homage on the famous V76 microphone preamplifier designed by the German
Broadcast System (NWDR) in the early 1950's and manufactured by several German companies.
