The K11 has USB*, optical input, coaxial input, 4.4mm, 6.35mm, RCA line, and coaxial output*. With more input and output than other common entry-level amplifiers, the K11 can meet the needs of consolidating capable audio settings. *USB connection to the phone for decoding does not consume your phone's battery. *Coaxial input and output share the same physical connector, coaxial output can only be used in USB mode. High power output Under a load of 32 ohms, the K11 can be pushed 1400mW in balance mode. This allows you to easily drive many HiFi earphones and headphones to maximize their potential. 3 gain levels, 3 volume curves. The K11 has three different gain levels, each gain level has its own volume curve. This allows the K11 to provide a better listening experience with different types of headphones even when using sensitive earbuds or over-ear headphones that are difficult to drive. Specially designed audio circuit and power supply. The slim build of the K11s has a specially designed audio circuit designed for superior sound quality. It is supported by over 16 low-noise LDOs for accurate voltage stabilization and is powered by an external 12V switching power supply. All of this leads to a purer, more robust power supply, resulting in stable high quality audio for a truly enjoyable music every time. Slim and stable The slim aluminum alloy body allows you to easily position the K11 anywhere and easily position your device to complement the rest of your desk. Thanks to the silicone non-slip pads, the K11 stays stable and firmly on the table.
