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.
