SL 900

2 x 450 w power amplifier

Summary & Images Specs Downloads & Support

Solid Dynacord amplifier technology at highly competitive prices.

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.
