Dynacord SL 900 2 x 4Ω0 w Power Amplifier
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 Amplifiers -> 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.
