BASIC Series - Intelligent Power

BASIC - that's meeting the tightest budgets and professional requirements
in reliability, flexibility and sound. Alone or in combination with the other
products of the Bittner portfolio.
The consequent realisation of the Bittner quality standards indicates once
more our understanding of the contracting business. It underlines our philosophy
that cost consciousness has nothing to do with giving up standards. Compromise
is a word unknown to Bittner Audio!
The incorporation of detent potentiometers, clip limiter, protection circuits for
any imaginable situation, as well as a first-class production process using only
highest-quality components made the BASIC series the choice of most contractors.

Certainly more than basic!
