Dynacord Professional Power Amplifiers manual

SL Series

Solid DYNACORD technology for universal application at highly competitive prices was the maxims for the development of the SL series of power amplifiers.

They 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, such as e.g. loudspeakers of the D-Lite, VariLine or Forum Line families.

SL series power amplifiers are equipped with protection against overheating, overload, short-cir- cuits, high frequencies and DC at the output.

Damage to the end transistors through the feedback of electrical energy is prevented by the back EMF protective circuitry.

When powering up, a relay delays the switching on of the power out- puts. In addition, a power-up cur- rent limiter prevents the blowing of the mains fuses.

Fast audio processors continuous- ly compare the input and output signals. In the event of any non- linearity, the processors send con- trol signals to the limiters, which dynamically reduce the input gain of the power amplifier.
