DOUK AUDIO L1 Line Level Preamplifier

The Douk Audio L1 is a compact line preamplifier designed to boost the output level by up to 20 dB of low-voltage audio sources. It relies on an amplification circuit with adjustable gain, a wide frequency response and an interchangeable NE5532P operational amplifier, to match the signal to the requirements of various Hi-Fi devices.

Douk Audio L1: Preamplification and adjustable gain

The Douk Audio L1 is a line preamplifier designed to boost the output level of low-voltage audio sources by up to 20 dB. Its amplification circuit operates at 26 V to provide an output voltage of ±12.5 V, allowing the level of sources such as a television, a game console, an MP3 player, a smartphone or a tablet to be aligned with that of the other devices in the setup.

Thanks to its various interfaces, the L1 fits between a source and an amplifier to compensate for an insufficient output level or to allow the use of a longer connection between components. Its adjustable gain range matches the signal strength to the system's needs, while maintaining a wide frequency response and a high signal-to-noise ratio.
