The Simplefly SF4802 Passive Dual-Channel Magnetic Bridge DI Box is a high-performance, advanced device designed to convert high-impedance, unbalanced signals into low-impedance, balanced signals. Ideal for musicians, audio engineers, and performers, this passive DI box ensures clean, high-fidelity signal transmission with no distortion or noise.

Features

• Magnetic Bridge Technology: Provides seamless high-to-low impedance conversion and superior signal balancing, while rejecting stray DC voltage. This technology helps eliminate hum and buzz caused by ground loops.

• Designed for High Output Instruments: Perfectly suited for high-output bass guitars, it handles large signal levels effortlessly, delivering distortion-free sound transmission even on stage.

• Dual-Channel Design: Offers versatile functionality, making it compatible with various audio equipment, including instruments and keyboards. It minimizes signal loss and noise during transmission.

• REV180° Switch: Reverses pins 2 and 3 of the XLR connector, making it ideal for connecting to older equipment or merging microphone and instrument signals into a single input to prevent phase cancellation.

This DI box is built to deliver reliable performance for both live performances and studio environments, maintaining pristine signal quality with minimal noise interference and loading.
