The eco-friendly choice

The Knoll KES400 and KES600 are class A/B amplifiers that produce 50 watts per channel at 8 ohms and 70 watts per channel at 4 ohms. While offering unparalleled reliability, power and sound quality the KES400 and KES600 offers a Knoll exclusive, the Eco-System™ circuit. This patent pending circuit determines which of the 12 stereo channels (6 pairs) are in use and delivers power only to those channels needing it. The channels that are “off” are truly off, not in “standby” or “mute”. With this circuit the active channels share more rail voltage resulting in more reserve power for the stereo channels in use.

The most important feature of the Eco-System™ circuit is the electrical savings that is delivered to the owner over what a comparable class A/B amplifier will cost to operate. The typical homeowner will see a savings of a hundred dollars or more per year in actual electrical costs and that can be multiplied when taking into account the increased costs of air conditioning the home to extract unwanted heat produced by a typical multi- channel amplifier. The KES400 and KES600 also feature a very quiet energy saving thermostatically controlled fan. A comparable amplifier without the Eco-System™ circuit (we should know, we make lots of them) uses about 14 times (65 watts) as much power while idling in standby. By comparison the KES600 with Eco-System™ uses under 5 watts while idling!

For over 15 years Knoll multi-channel amplifiers have sold around the world because of their legendary reliability and unparalleled sound quality. The KES400 and KES600 take the next logical step by being eco-friendly. Please consider the environment when choosing your next system.
