BURMESTER Model897

Commentary

A preamplifier with improved cost performance while inheriting the design philosophy and performance of Model877.

An adjustable potentiometer is used to adjust the volume.
There was also a stepped attenuator type as an option.

The phono inputs are modular and can be connected to the balanced / unbalanced switchable phono MC (standard), unbalanced phono MM (optional) and balanced CD (optional) by changing the board.
