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.

Solid DYNACORD technology for fixed installations at very competitive prices. DSA power amplifiers offer a very high, stable output with high efficiency at a high performance level and are therefore the ideal choice for typical fixed installation applications. The connectivity consequently provides Phoenix type in/outs, the input level controls are located on the rear panel, also a switchable high-pass filter (50 Hz, 18 dB/oct) and a Ground Lift switch. The POWER REMOTE connector makes the task of remote controlling the power amplifier as well as switching it on and off simple. For further remote-supervision and –control possibilities and integration into IRIS-Net networks, an optional remote control module (RCM-810) is available.
