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

Mutiple input/output interfaces: with 3.5mm AUX/stereo RCA/5-DIN inputs and stereo RCA/5-DIN 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.
With built-in amplification and voltage boost circuit: adjustable gain to match better with different audio sources, support DC 5-24V wide input voltage that can share the power supply of amplifiers, while L1 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 change other op amps to enjoy different sound and bring much DIY fun for audiophiles. High-qaulity sealed potentiometer, with wide frequency bandwidth and excellent dynamic response, the sound is smooth and natural, warm and delicate with ultra-low distortion.
Mini size with exquisite appearance, compact and all-metal design for durability and shielding the electronics from electromagnetic interference with noise rejection. Perfect design in size and function, suitable for many scenarios to increase the output level, such as home stereo system, mixer or speaker setup, karaoke, audio recording, party, live stage event etc.
