• Gamintojas: DLS
• Modelis: S4

DLS Signature S4 is a flag 4-channel amplifier class AB designed for systems where absolute signal purity, high dynamics and full control over speakers are a priority. This reference design, developed in collaboration with Gordon Taylor (Dr. Amp), offers 4 x 130 W RMS power at 2 Ω and an outstanding signal-to-noise ratio of 116 dB, which builds the signature series' signature "black background". Thanks to the compact housing with active cooling and the unique ability to bypass the preamplifier section when working with the DSP processor, the amplifier allows to obtain the maximum clear, unchanged signal and fully unleash the potential of the audio system.

DLS Signature S4 at a glance, which are the most important features:

✨ Flag construction class AB – guarantees smooth, saturated, natural and extremely precise sound tuned by Gordon Taylor.

✨ Reference parameter S/N 116 dB – extremely low noise creates a perfectly black background, highlighting the smallest microdetails.

✨ Surgical speaker control – damping factor above 300 ensures excellent membrane handling and fleshy midbass.

✨ Bypass preamplifier for DSP – the ability to disable filter sections to deliver an intact signal from the sound processor to the amplification stage.

✨ Author’s active cooling system – built-in internal fan allows you to maintain very compact dimensions of the housing.

User manual

Benefits for you:

⮕ Reference signal clarity and sound with authority

With an outstanding signal-to-noise ratio of 116 dB, the amplifier offers pristine clarity and reference silence in the background, from which microdetails of recordings flawlessly emerge. The AB-class design, tuned by Gordon Taylor, provides sound smooth, saturated and natural, devoid of artificial sharpening.

The very high damping coefficient (>300) and negligible harmonic distortion (THD < 0,065%) ensure absolute control over the speakers, which translates into a fleshy midbass, cclean midrange and analytical treble without hearing fatigue even during long listening sessions.

⮕ High-End without compromise

Signature S4 offers a very important function of disabling the internal section of the preamplifier. In cooperation with an external DSP sound processor, this allows you to completely bypass the amplifier filters, thanks to which to the degree of power receives the signal as clean and unchanged as possible.

Despite advanced parameters and high stability, the device maintains extremely compact dimensions. This is due to the proprietary, active cooling system with an internal fan that efficiently dissipates heat, eliminating the need to build a large and bulky housing.
