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.
Features
- Standard input/output interfaces: with 3.5mm AUX/stereo RCA inputs and stereo RCA outputs, can be compatible with most low-volume audio sources such as ipod, ipad, phone, TV, MP3 player, potable CD player, computer, video game etc., and boost their output to the level needed to drive amplifier or speakers.
- Adjustable gain and voltage boost circuit: with built-in amplification and voltage boost circuit, adjustable gain to match better with different audio sources, while L1 MINI can always work at a high voltage of 26V to provide ±12.5V high output amplitude and max 20dB high gain.
- Unique design and HiFi clear sound: double-side PCB design, NE5532P op amp with pluggable socket design, convenient to upgrade other dual op amps to bring more playability. The high-quality sealed potentiometer ensures a wide frequency range and excellent dynamic response, delivering smooth, warm, and natural sound with ultra-low distortion.
- Versatile application scenarios: perfect for boosting the volume of portable audio devices to match home stereo systems, enhancing karaoke or CD/DVD players for lively parties, and providing external volume control for audio sources lacking adjustments, ideal for mixer or speaker setup, audio recording, party, live stage event etc.
- Super mini size with durability: with a compact size, it is easy to carry and fit into any audio system without taking up much space, perfect for on-the-go use. The all-metal design ensures durability while shielding electronics from electromagnetic interference and reducing noise.
Warm tips:
1.Equipped with USB to DC cable, NOT include power adapter, can use phone charger/power bank to power it.
2.It is not recommended to use computer to power L1 MINI, as it may cause noise interference.

thank you

Bought it for my wanbo mozart 1 pro (2025) projector's 3.5 output, which limits volume level. With this preamp, volume level is increased significantly, exactly what I was looking for!

great prodict

This is exactly what I was looking for. Sometimes when I’m watching YouTube, the audio is too low even with the volume on my iPad and my Bluetooth speaker set to maximum. This little amp fixes this problem by amplifying the audio from the headphone jack and plugging it into the aux input on the speaker.

This preamp from Douk Audio is a great addition to my music system in my drum room. I play all my songs from a phone, but they have notoriously low outputs. I run the phone output into this preamp and then on to the main amp for a nice clean boost that actully allows me to utilize the full potential of my amp and speakers. I was really surprised at the difference this gadget made in my sound. Simple installation with an easy to use interface-a volume knob. Great addition, glad I got it.
