* SOFT START The amplifiers feature “soft start“ as well as switch-on and -off delay in order to conserve the loudspeakers and avoid switching and cracking noises.
* PROTECTIVE CIRCUITS The LSA series has protective circuits against short circuit and overheating as well as current limitations, switch-on/-off delay, DC voltage fault protection and a clip limiter circuit against overstressing the loudspeakers.
* PERFECT COOLING SYS. The amplifiers are equipped with ball-bearing, automatic cooling fans (two on the LSA-2000, four on the LSA-3400 / LSA-4000), which automatically adapt their speed depending on the amplifiers´ strain. The air duct, embedded in the casing, provides excellent cooling in connection with the fans and ventilation slots.
* MODERN DESIGN The switching power amplifiers of the LSA series feature a modern and functional design and are economically structured in 19“ technology (2 RU). They are suited best for demanding application and show, even at full strain, no sign of stress.
* INFORMATIVE DISPLAY The front panel of the LSA series is designed in such a way, that any important information on the current operating status is indicated optically all the time.These LED displays are: power, clip, protect, signal as well as mono/parallel.
* ACTIVE SWITCHING In the LSA series, output stages with switching power supply are used. Depending on the strain, the switching power supply picks up the accordant amount of electricity.
* STABLE AT 2 OHMS The amplifiers LSA-3400 and LSA-4000 are designed for highest requirements and therefore may also be operated with 2 ohms.
