This mini stereo line level booster preamp raises low-volume sources to the level needed to drive an amplifier or speakers, with 3.5mm AUX, stereo RCA, and 5-DIN connections for phones, TVs, MP3 players, and computers. Adjustable gain, DC 5-24V input support, and an L1 path that can reach 26V with plus or minus 12.5V output and up to 20dB gain provide stronger drive. A pluggable NE5532P op amp, sealed potentiometer for smooth natural warm sound, and an all-metal enclosure support home stereo, mixer, karaoke, recording, and stage setups in a compact shielded housing.
Multiple input and output interfaces include 3.5mm AUX, stereo RCA, and 5-DIN inputs plus stereo RCA and 5-DIN outputs for low-volume sources such as a phone, TV, MP3 player, or computer in a compact home or event preamp
A built-in amplification and voltage boost circuit offers adjustable gain to match different audio sources and supports DC 5-24V wide input voltage that can be shared with amplifiers in the same stereo, mixer, or event setup
The L1 circuit can work at a high voltage of 26V to provide plus or minus 12.5V high output amplitude and a maximum 20dB high gain for stronger drive to amplifiers or speakers from a weak line level source on this 20dB line level booster
Double-side PCB design with an NE5532P op amp in a pluggable socket makes it convenient to change other op amps for different sound character or DIY swapping on the mini stereo line level preamp board in this mini all metal preamp
A high-quality sealed potentiometer yields wide frequency bandwidth, excellent dynamic response, smooth natural warm sound, and ultra-low distortion for the volume and gain control on this compact line level booster with a sealed potentiometer
Mini all-metal construction adds durability and shields electronics from electromagnetic interference, suiting home stereo, mixer, karaoke, recording, and stage use in a compact line level booster with volume control
