Douk Audio L1Mini Stereo Line Level Booster Amplifier 20dB Gain Volume Control Audio Preamplifier

The L1 Mini is an upgraded version featuring a downsized form factor and a simplified interface. This stereo amplifier has built-in voltage and power amplification circuits to boost the output of virtually any line-level audio source, including TVs, video games, MP3 players, iPods, smartphones, and tablets, by up to 20dB. Featuring a 3.5mm AUX/stereo RCA input and stereo RCA output, it's compatible with most low-volume audio sources, including iPods, iPads, smartphones, TVs, MP3 players, portable CD players, computers, and video games. This boosts the output to the level needed to drive amplifiers and speakers. With its built-in amplification and voltage boosting circuits, the L1 MINI allows you to adjust the gain to suit various audio sources, and it always operates at a high voltage of MAX 26V, providing a high output amplitude of ±12.5V and a high gain of M 20dB. With its wide gain range, broad frequency response, excellent signal-to-reaction ratio, and HiFi sound, it allows you to increase the output level of your audio devices to match other sources or to use longer cable runs than usual. The NE5532P op-amp features a double-sided PCB design and a named socket design, offering convenience for upgrading to other dual op-amps for enhanced playability. High-quality shielded potentiometers ensure a wide frequency range and excellent dynamic response, delivering a smooth, warm, and natural sound with ultra-low distortion.
