Douk Audio L1

Introduction

Douk Audio L1 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 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.

Warm Tips

  1. 3.5mm AUX input with priority, please make sure AUX cable has been disconnected if you want 5-DIN or stereo RCA input.
  2. 5-DIN and stereo RCA output can work at the same time.
  3. Equipped with USB to DC cable, NOT include power adapter, can use phone charger/power bank/computer to power it.
