Dynacord L 500 Product Details
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.
