User Manual & Driver of Douk Audio L1MINI

Big difference maker from low level sources

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.
