Trinity PREAMP, User Manual

THE LOW NOISE INPUT STAGE
The TRINITY PREAMP is based on the same architecture of the TRINITY PHONO. It uses the same extraordinary gain stage,
which is based on 12 ultra-linear fully differential gain stages.
The PREAMP is fully balanced from the input to the output.
The TRINITY PREAMP uses 12 gain stages in parallel to reduce the input noise voltage by a factor of
12 3.5 10.8dB
= ≡
The Gain can be set during the assembling. The regular gain is 6dB, other gain can be realized on request.
Another advantage of using 12 gain stages is that the load of the volume control is split to 12 gain stages. That means each
gain stage has only to deliver 1/12 of the necessary current and therefore stays in a Class A mode for all possible signal levels.
The DC servo allows single ended adapter on each input connector.
