With the Sound StormLaboratories EVOLUTION MOSFET amplifier series, we are introducing eleven new amplifiers, all designed in the USA. This new series includes a two monoblock amps, six 2-channel, and four 4-channel amplifiers. All EVOLUTION models feature variable low pass and high pass crossovers and variable input gain controls. They also incorporate an input voltage sensistivity selector for added systemflexibility. For further flexibility in the use of a subwoofer, 0-+18dB Bass Boost control has been included on all amplifiers. You can control the subwoofer level with the remote level control module. Sound Storm understands that amplifiers are placed in many different kinds of installations, so we incorporated a very flexible system of controls in these amplifiers in order to help you integrate the ampinto your system regardless of the nature of your input source.
What is included?
When first unpacking your new amplifier, please check first that the package contains all of the items below. If something is missing, contact the store where you purchased the amplifier. • EVOLUTION amplifier • Remote subwoofer level control •High input cable with connector • Four (4) mounting screws

About 2 Ohm operation
Your EVOLUTION amplifier has been designed to operateefficiently at loads down to 2 Ohms. This means that you can install four 8 Ohm speakers per channel, when using parallel wiring. Increasing the number of woofers per channel at low frequencies (below 100Hz) produces an acoustic coupling effect. This acoustic coupling effect increases your power output by about 3dB per speaker, or the equivalent of an additional 10W per speaker. When operating at 2 Ohms,the amplifiers will increase their output power by approximately 50%. The current draw will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2 Ohm load. If you lack adequate current, your music reproduction will be distorted.
