The new EVOLUTION Black Series of SSL amplifiers is the stunning result of…well, EVOLUTION. Building on the platform of SSL's most popular amplifier series, this EVOLUTION Series continues to deliver outstanding performance and immense power. Research of the market told us that providing a wider variety of monoblock amps in a series is a good thing. We listened; our engineers delivered. The EVOLUTION Series now contains three Class D monoblock amplifiers capable of 1 Ω operation and two full-range Class A/B monoblock amplifiers capable of 2 Ω operation. Additionally, the EVO Series contains one two 4-channel amplifiers, and four 2-channel amplifiers. Great care was put into the development of SSL's new EVOLUTION Series of amplifiers. High quality components are used throughout the series, so that the monoblocks can pound for hours while the multi-channel EVOLUTION amplifiers reproduce the full range of the artist's musical intentions with astonishing fidelity. The EV2.1200 is a powerful, full range Class A/B 2-channel amplifier with a variable low pass crossover, fixed high pass crossover, variable bass boost, and low and high level inputs, and, of course, a wired remote subwoofer level control.
