Power amplifier named "The Precision Power amp" by the developer.

DB-6 are stereo power amplifier and the monophonic power amplifier with which DB-6M made bridge connection of the right-and-left channel of DB-6 inside.

The height of distorted little and stability and the smooth point of recovery at the time of a clip are thought as important, and it is designed.

The LED peak indicator is carried.
