The E11 Headphone Amplifier from Fiio is a compact and lightweight headphone amplifier that offers high-quality audio, ideal for portable music devices. The amplifier has standard 3.5mm input and output connectors for compatibility with a variety of MP3 players, CD players, computers, earbuds, headphones, and other devices. It has a heavy-current 3-channel amplified circuit that lowers output impedance. It also provides high efficiency and a low-noise power boost. It provides precise and even sound pressure levels and a wide dynamic range.
The convenient volume control uses a closed APLS potentiometer to ensure low noise and excellent channel balance. The amplifier offers 3 levels of bass boost and 2 levels of gain to meet your personal preferences and adapt to different sound sources. There are also high and low voltage options to meet different needs. An auto-lock protective circuit will turn the amplifier off automatically in the event of abnormal activity in order to protect your headphones and minimize the risk of hearing damage.
The amplifier operates on a high-performance BL-5B Lithium battery that is easily replaceable. The battery provides approximately 10 hours of operation per charge, allowing you to listen all day. The amplifier has charging and power indicator LEDs to give you a visual cue of operation status. A charge priority function will cease operation while the amplifier is charging. Once the battery has been charged and the amplifier is unplugged, operation resumes.
