Dynacord SL1800

Robust Dynacord amplifier technology at highly competitive prices. These amplifiers offer high, stable power output and a high efficiency factor at a high performance level and are therefore the ideal choice for driving many mobile and club systems. The SL series power amplifiers are equipped with a comprehensive protection package and dynamic limiters. An integrated, switchable Low-Pass Notch filter (a typical Dynacord special feature) smoothes the frequency response and optimizes the transient behavior of the speakers.
