SSL EV200.2 EVOLUTION 200-watts Full Range Class A/B 2 Channel 2-8 Ohm Stable Amplifier View larger Class A/B Topology A class A/B amplifier uses two groups of transistors and it is generally considered to be the best compromise of the two classes put together. Class ‘A’ and class ‘B’. A pure class ‘A’ amplifier typically has an enormous amount of current flowing through its output transistors with no audio signal. A pure class ‘B’ amplifier has NO current flowing through its outputs with no audio signal. This eliminates virtually all of the crossover distortion that’s possible with class ‘B’ amplifiers. A class A/B amplifier is much more efficient than a class ‘A’ but without the possible distortion of a class ‘B’. Features 1) 2 Ohm Stable Stereo Operation 2) Soft Turn-On Circuit 3) Remote Turn On / Turn Off Circuit 4) Variable Input Gain Control 5) Black Aluminum Heatsink 6) Nickel Plated RCA Low Level and High Level Inputs 7) LED Power Indicators Fixed Low-Pass Crossover (120 Hz on CH 3/4) View larger Speaker, Battery, Remote and Ground Terminals Plus Fuse View larger Fixed Low-Pass Crossover (120 Hz on CH 3/4) Subwoofers reproduce sound based on a number of different low-range frequencies. This process is called the crossover effect and occurs because the vast majority of audio systems cannot cover the entire spectrum sufficiently to minimize sound distortion and maintain an appropriate frequency ratio. In the case of our EV200.2 amplifier, a fixed crossover is offered so that you, the listener, can have the opportunity to hear the low subwoofer frequency at which the crossover occurs with minimal distortion. Full Range View larger Full Range The “Full” l Range option will change to offer a complete range of frequencies that you need for your coaxial speakers. This gives your tweeters and midrange the dynamics necessary for those highs to come through nicely. Specifications View larger Low And High Level Inputs View larger Low And High Level Inputs The EV200.2 has two different ways that you can get a signal into it. One is called Low level input and the other is called High level input. A low level input is measured in voltages. It comes in the form of RCA outputs from the back of your receiver and goes to the RCA inputs on your amplifier. A high level input is measure in wattages. It comes in the form one positive and one negative wire from the back of your receiver to and goes to the input terminal of your amplifier in the same wire form. Low-level (RCA) input wiring is preferred for best audio performance. Always use a high-quality RCA cable for best audio performance. NOTE: Do not connect both the high level and low level inputs from your receiver to your amplifier at the same time!
