Product Description

The preamplifier is "control central" for any system. It provides source selection, adds gain when necessary, lets you adjusts levels, balance, and other parameters, and sends the signal off to the system's "engine room", the power amp. As the switching and control center, the preamp must be extremely quiet and distortion free. Because the signals it receives and then sends out to the power amp will be multiplied hundreds of times before you hear them. So if the preamp changes the signal in any way, it'll be magnified big time when you finally hear it! Fundamentally then, a great preamp must allow control flexibility and source selection, while adding or taking away nothing from the original source. The GFP-750 can be operated either as a completely "passive" (no gain) unit, with absolutely minimal sonic impact, or as a sophisticated active (utilizing active components and providing gain) preamplifier. In passive mode the GFP-750 is strictly a "line level input switcher", with its high quality four gang volume attenuator that lets you adjust the volume. While its active circuitry is both unique and superb (details later), you always have the option of using the GFP-750 in this ultimate passive mode, for control with maximum fidelity.
