Introduction
Douk Audio L1 MINI is an upgraded version of L1, featuring a more compact size and simplified interfaces. It is a stereo amplifier with built-in voltage boost and amplification circuits, designed to boost the output of virtually any line level audio source (such as TV, video games, MP3 players, ipod, phone, tablet etc.) to max 20dB. L1 MINI features its wide gain range, wide frequency response, excellent S/R and HiFi sound, to bump the output level of the audio devices which are with an inherently low level output so as to match other sources, or to allow the use of a longer cable run than normal between components.
