Portable Headphone Amplifier 2x OPA NE5532
This FX-Audio PH-01 is a small portable headphone amplifier, simple but very powerful. Integrating an amplification circuit with two NE5532 AOPs mounted on DIP8 and therefore interchangeable, it offers a very nice musicality and a significant power gain. The amplifier also offers two gain levels (Low / High) to fit the vast majority of headphones. It is therefore perfectly adapted to offer a boost to a DAP or smartphone when you are on the move. Indeed, its small dimensions allow the PH-01 to easily slip into a pocket and be forgotten.
Warning: Opening the unit and changing the AOPs will void the warranty.
