DLS Signature S4 four channel amplifier

.

The DLS Signature S4 is a reference 4-channel analog car amplifier developed together with Gordon Taylor.

In 2019, 40 years have passed since the creation of DLS. For four decades, they've been giving auto hifi enthusiasts exactly what they wanted, but they knew they could do even better. Together with Gordon Taylor, they are now embarking on a new path to perfection.

Silent

A really great amp makes no sound at all by itself. The Signature Series has unmatched low distortion and extremely high signal-to-noise ratio, so you can hear only the music and experience new details in your favorite tracks with warm clarity and tight mid-bass with impressive authority.

Optimized for perfection

No detail was left unedited. From its own cooling system to the power supply. Each channel has even been trimmed individually and each component synchronized with each other so that the individual channels work in perfect harmony. When used in conjunction with a digital audio processor, there is the ability to bypass all preamplifier circuitry, allowing the DSP to gain complete control over all audio tuning parameters. This allows a clean and unaltered signal to reach the amplification stage in full without sonic degradation.
