L1 Mini Stereo Line Level Booster Amplifier Audio Preamp with 20dB Gain and Volume Control

Multiple input/output interfaces: Features 3.5 mm AUX, stereo RCA, and 5-DIN inputs and outputs. It is compatible with most low-volume audio sources such as iPod, iPad, phones, TVs, MP3 players, portable CD players, computers, and video game consoles, and can boost their output to the level required to drive an amplifier or speakers. Built-in amplification and voltage boost circuit: Provides adjustable gain to better match different audio sources. Supports a wide DC input voltage range of 5-24V, allowing it to share the power supply with amplifiers. The L1 circuit operates at a high voltage of 26V to deliver ± 12.5V high output amplitude and a maximum gain of 20dB. Unique design and
Hi-Fi clear sound: Utilizes a double-sided PCB design and an NE5532P operational amplifier in a pluggable socket, making it convenient to swap in other op-amps to enjoy different sound characteristics, offering DIY enjoyment for audiophiles.
High-quality sealed potentiometer: Offers wide frequency bandwidth and excellent dynamic response. The resulting audio is smooth, natural, warm, and detailed with ultra-low distortion.
Mini size with exquisite appearance: Compact, all-metal construction ensures durability and shields the electronics from electromagnetic interference for effective noise reduction. Perfectly designed in size and function: Suitable for many scenarios to increase output levels, such as home stereo systems, mixer or speaker setups, karaoke, audio recording, parties, and live stage events
