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. Features * Excellent audio performance * Symmetrical topology * Ultra-low distortion * Generously dimensioned power supply units * Suitable to be operated on loads down to 2 ohms * Suitable to drive complex loads with phase angles of ± 90 degree * Extensive protection circuitry * Unique Back-EMF protection * Switchable limiters * Switchable Hi/Lo-Cut filters * Robust steel chassis * Exceptional low noise front-to-rear air-flow * XLR-type inputs and direct-outs * LED display shows On, In, Out, Limit and Protect * Highly reliable operation

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!
