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!

The model L 500 is a 2 x 250 Watts Power Amplifier. Linear Precision Series
power amps combine excellent audio performance, modern and innovative
circuit design, meticulous and exceptionally rigid construction, and the highest
levels of operational integrity and reliability with an appropriate and more than
realistic price. The robust steel chassis provides outstanding torsional strength
through L-shaped side panels reaching under the thick aluminium front panel.
Thermal breakers prevent the power supply units from being damaged by thermal
overload. Electronically controlled fans provide sufficient front-to-rear airflow and
a special cool air diverter takes care of thermal stability. The fans? noise-level is
extremely low which provides the possibility for studio use. If necessary, a supplied
air-filter can be mounted behind the front panel ventilation louvres.
