MAIN FEATURES

DLS Signature S4 4-Channel Class AB Amplifier

 

The DLS Signature S4 is a premium 4-channel Class AB amplifier engineered to deliver exceptional audio quality with ultra-low distortion and an extremely high signal-to-noise ratio. As part of the flagship DLS Signature Series, it provides the warm, natural DLS sound signature with outstanding clarity, dynamic range, and precise speaker control for high-end car audio systems.

 

Every aspect of the S4 has been meticulously refined, from its precision-tuned power supply to its advanced cooling system and individually calibrated channels. When paired with a Digital Sound Processor, Direct DSP Mode bypasses the preamp circuitry, allowing a pure, unaltered signal to reach the amplifier for maximum sound quality and precise system tuning.
