DLS Signature Series S4 - Class A/B Four Channel Amplifier 90W RMS X 4
Silence is Golden
A truly great amplifier does not make any sound at all. The Signature series has unrivalled low distortion and an extremely high signal-to-noise ratio, letting you hear only music and experience new details in your favourite songs with a warm clarity and a firm mid bass with impressive authority.
Optimised for perfection
No detail has been left untweaked, from the custom cooling system to the power supply. We have even trimmed each channel individually and synchronised every component with each other to perform in perfect harmony.
When used together with a Digital Sound Processor there is an option to bypass all preamp circuitry, letting the DSP get complete control of all sound tuning parameters. This allows a clean and unaltered signal to reach the amplifying stage in full without sonic degradation.
Enjoy music in full, unaltered and perfect, with the Signature series.
