Product Spotlight: The Concealed Strength of the SS4b Multi-Channel Amplifier

June 21, 2018

The Ninja are discrete, versatile, precise and reliable. They crawl, soar, strike and vanish. Hidden in plain sight among DD Audio’s amplifier line-up is one such covert killer. Often overlooked, never overwrought, this sharp and powerful little shinobi has earned respect from all who employ its skills. For that reason, we have chosen the SS4b for this month’s product spotlight.

Loaded into the compact SS chassis, this amplifier is ideal for stealth installations. Its discrete class D circuitry delivers tremendous power without sacrificing fidelity or thermal load handling. The highly durable screw block terminals support clean and lasting connections. With individually selectable high pass and low pass crossovers, the SS4b effortlessly bends frequency bands to its will.

Subtle, versatile, powerful, exact, and unrelenting. The SS4b is your system’s shadow veiled assassin — channeling powerful and efficient blows that reverberate through the domain of its shogun.
