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.

How do I add 2 more sets of speakers to it Mark Catalano asked on February 25, 2024

The GFA-565se
250W@8ohm/channel or 350W@4ohm/channel
Therefore, your other 2 sets of speakers are 240W each (120W@8ohm+120W@8ohm, total 240W@4ohm). The wattage of the power amp must be 1.5 times to 2 times the wattage of the speakers. The power output of the power amplifier must be 1.5 times to twice the wattage of the speakers.

Perfect match for my Maggies LRS+ not a lot of info out there on this combo, so decided to take the plunge and see how it adds up. Currently have a Jolida Fusion tube preamp connected via xlr inputs and I hear nothing but dead silence out of the amp at idle and at full volume with nothing playing. The amp barely gets warm. Makes the LRS+ sound phenomenal. I have around 50 hours so far on the break in process, but if this is any indication of the sound now, and will get better as time goes on, this would be a sleeper of a system for 3 grand. I am happy with the purchase.

The GFA 565se is well made and still has the AdCom look, nice. Some users say it generates a lot of heat, I have not seen this problem. Nice unit.

    I appreciate the ADCOM brand, The all-new CLASS A/B 250 watts per channel in 8 Ohms with XLR inputs, premium RCAs, and detachable power cord. Full warranty & free delivery.

  2. Y. Jackson

    The result is lower distortion, better dynamic range, improved damping factor and greater stability and separation of individual instruments on the sound stage.

  3. Daniel

    I received my product on time in perfect shape with a great deal. I was a bit skeptical of ordering out of state, but it was great. Thank you.
