The INTUFORCE 4SDL160 is -- despite its simple front panel layout -- a highly versatile system amplifier for low-impedance sound systems. Via its comprehensive rear-panel controls, it can be set from a 4-zone amplifier to a dual stereo amplifier or a 2.1 satellite and subwoofer system amplifier. The latter is facilitated by its built-in active crossover with 4 selectable crossover frequencies and its bridging feature for the 3rd and 4th channel. Larger systems are easily set up via the link connectors. Built on cutting edge class D technology, the unit is convection cooled and hence suitable for applications sensitive to background noise. The conservative switch mode PSU design delivers not only peak power, but also long-term endurance. Best to be combined with 2 or 4 satellite speakers and a subwoofer as one compact system.
