The GSZ44 and GSZ67 systems are powered by the award–winning Eco-System amplifier that shuts off the amplifier (or channels within the amplifier – depending on what’s being used or not) to save power with no turn-on artifacts. The GSZ series also offers two different type keypads in the four most popular colours to fit into any décor.

The GSZ67 has a12-channel class A/B amplifier that produces 50 watts per channel at 8 ohms and 70 watts per channel at 4 ohms. The smaller GSZ44 has an 8-channel class A/B amplifier that produces 30 watts per channel at 8 ohms and 35 watts per channel at 4 ohms. While offering unparalleled reliability, power and sound quality these GSZ systems offer the Knoll exclusive Eco-System circuit. This patent-pending circuit determines which of the 8 or 12 stereo channels (in 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”. As an added bit of ingenuity, the circuit enables the active channels to share more rail voltage resulting in more reserve power for the stereo channels in use.

Given today’s energy-conscious consumers, the most timely benefit of the Eco-System circuit is the electrical savings that the owner gets over what a comparable class A/B amplifier would cost to operate. The typical home owner will enjoy a savings of hundred dollars or more per year in electrical costs and that can be multiplied when taking into account the increased costs of air conditioning to extract unwanted heat produced by a typical multi-channel amplifier. Comparable amplifiers without the Eco-System circuit would use about 14 times (40 – 80 watts) the amount of power while idling in standby. By comparison the GSZ44 with Eco-System uses under 2 watts while idling!

According to Knoll Systems VP of Marketing and Sales, Richard Hanson, “These Eco-System multi-room audio systems are perfectly timed for today’s marketplace. Homeowners that want multi-room audio as a part of the everyday lifestyle want great sound. The 8 and 12-channel Eco-System amps sound fabulous, thanks to Kevin Knoll’s years of experience and design savvy. But these same customers also want to be responsible and only put in systems that are energy-efficient at the same time. These Eco-Systems let the homeowner fill their homes with great sound, while showing their appreciation for energy conservation. It’s the perfect entertainment match for today’s economy.”

The GSZ 44 comes complete with four keypads, a controller amplifier and is also expandable by daisy chaining two or more together to make larger systems. It offers twice the power and a tenth the energy consumption of its competitors.

The GSZ67 comes complete with 6 keypads, a controller amplifier and also expands by daisy-chaining two or more together to handle larger applications.

The new GSZ systems are aiming to be record breaking product for Knoll Systems by virtue of their Eco-System technology, ease of installation and affordable cost. Knoll’s experience with the custom installation channel also means that these new systems offer unparalleled reliability, power and sound quality.
