Simplefly SF4802 Passive Dual-Channel Magnetic Bridge DI Box is an advanced, high-performance device designed to convert high-impedance, unbalanced signals into low-impedance, balanced signals. This passive DI box is ideal for musicians, audio engineers, and performers who require clean, high-fidelity signal transmission without distortion or noise.
Features
Magnetic Bridge Technology: Ensures high-to-low impedance conversion and excellent signal balancing while rejecting stray DC voltage. This helps in eliminating hum and buzz caused by ground loops.
Designed for High Output Instruments: Especially suited for high-output bass guitars, it handles large signal levels effortlessly, ensuring distortion-free sound transmission on stage.
Dual-Channel Design: Offers rich functionality, making it versatile for various audio equipment, including instruments and keyboards. It significantly reduces signal loss and noise during transmission.
REV180° Switch: Reverses pins 2 and 3 of the XLR connector, making it perfect for connecting to older equipment or merging microphone and instrument sources into a single input to avoid phase cancellation.
This DI box is designed to provide reliable performance for both live performances and studio environments, ensuring pristine signal quality with minimal loading and noise interference.
