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.
