4CH Amp


The INTUFORCE™ 4SDL160 is – despite its simple front panel layout – a very versatile system amplifier for LoZ installed 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 & subwoofer system amplifier. The latter is facilitated by it’s in-built active crossover with 4 selectable crossover frequencies and its bridging feature for the 3rd and 4th channel. 

Feature Packed

Larger systems are easily set up via the link connectors. Built on cutting edge class D technology, the unit is convection cooled and hence also suitable for applications sensitive to background noise. 

Built to last

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.

Perfect for any space
