Dual Channel Audio Preamp 6.35mm Balanced Input 0‑20dB Gain Control for Mic and Instrument DC5V‑12V

This dualchannel sound amplifier provides flexible input options, independent channel control, and straightforward power management for reliable audio routing in studio and live environments. It is designed to preserve signal integrity over long cable runs while remaining compatible with common audio gear. Key benefits Flexible input choices for long runs: Balanced input circuit accepts either single ended or balanced connections, with single ended using a large two core mono plug and balanced using a large three core stereo plug, reducing noise over long distances. Independent channel control: Two separate amplification channels with individual gain knobs allow one channel to be adjusted without affecting the other, providing precise level control and simpler mixing. Wide operating voltage and simple power control: Works from DC 5V to 12V and includes an independent power switch plus a simple LED indicator for clear power status. Broad compatibility: Non balanced single ended outputs use standard 6.35mm 1/4 inch ports for input and output, making the unit compatible with instruments, mixers, recording interfaces, and PA systems. Main features Balanced input design supporting both single ended and balanced wiring for long distance transmission and reduced interference. Dual channel amplification with separate gain adjustment range from 0 to 20 dB per channel. Each channel usable independently or simultaneously without mutual interference. Output ports are non balanced single ended using 6.35mm 1/4 inch connectors for wide device compatibility. Operates on DC 5V to 12V with an independent power switch and LED power indicator for easy monitoring. Typical applications Small live performances: Use the amplifier to drive stage monitors or route instrument signals to a mixer, maintaining clean signal over longer cable lengths. Rehearsal and practice rooms: Connect guitars, keyboards, or electronic drums to the unit and adjust each channel independently to set practice levels without changing the other channel. Recording and project studios: Integrate the amplifier between instruments and a recording interface or mixer to preserve signal quality and manage channel gains during tracking.
