| The GFA-565se high power amplifier is capable of effortlessly driving a wide variety of loudspeakers, even those with exceptionally low impedances. It excels in maintaining high-power output consistently, even when faced with reactive impedances. Meticulous attention was given to ensure that the amplifier’s distortion remains minimal, especially when dealing with these complex loads, where the phase differences between voltage and current are significant. The GFA-565se incorporates an impressively robust power supply, featuring a generously sized transformer that powers a reservoir of 72,000uF filter capacitance. This setup ensures a substantial reserve of power capability. The transformer itself was purposefully engineered to provide exceptional regulation, guaranteeing unwavering voltages regardless of the amplifier’s power requirements. Notably, the GFA-565 possesses the ability to amplify DC signals and is unrestricted in its capacity to deliver energy across low-frequency and peak-bass ranges. Its gold-plated brass RCA input jacks with Teflon insulators exemplify the amplifier’s commitment to high quality. Additionally,the high power audio amplifier features a front-panel LED indicator alerts users to thermal overload conditions, enhancing the amplifier’s safety features. |
