Introduction
Douk Audio L1 MINI is an improved version of the L1, which features a more compact size and simplified interfaces. It is a stereo amplifier with built-in voltage increase and gain circuits that can raise the output of virtually any audio source with line level (such as TV, video games, MP3 players, iPod, phone, tablet, etc.) to a maximum of 20 dB. L1 MINI features a wide gain range, wide frequency response, excellent S/R and HiFi sound to increase the output level of audio devices that naturally have a low output level to match other sources, or to allow the use of a longer cable than normal between components.

Warm tips:
1. Equipped with USB DC cable, not included power supply, can use mobile phone charger/power bank to operate it.
2. It is not recommended to operate L1 MINI via a computer, as this may cause noise interference.

2. You want to increase the output level of karaoke players or CD/DVD players to turn your stereo music for parties or outdoor events into an exciting sound that is low noise and with high musical accuracy to listen and record.
