Commentary
A power amplifier named "The Precision Power amp" by its developers.
The DB-6 is a stereo power amplifier, and the DB-6M is a monaural power amplifier that internally bridges the left and right channels of the DB-6.
It is designed with an emphasis on low distortion, high stability, and smooth recovery during clipping.
Equipped with LED peak indicator.
