These amplifiers offer high, stable power output and a high efficiency factor on the high performance level and are therefore the ideal choice for driving a multitude of mobile and club systems. SL series power amplifiers are equipped with a comprehensive protection package and dynamic limiters.
The integrated, switchable Low-Pass Notch filter (a typical DYNACORD special feature) corrects the frequency response and optimizes the transient behaviour of loudspeakers.

HPS 1500 is a 2 channel power amplifier that delivers up to 2 x 750 W RMS @ 4 Ω (1500 W RMS bridged @ 8 Ω).

XLR inputs for patching in signals as well as Speakon ports for connecting speaker systems are provided for the maximum flexibility.
A forced air cooling system maintains a low operating temperature.

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.
