【HIGH-PRECISION SIGNAL CONVERSION】Our passive guitar DI box effectively converts high-impedance, unbalanced, line-level signals into low-impedance, balanced, microphone-level signals – ensuring optimal audio transmission to mixers, audio interfaces, or PA systems. 【VERSATILE INPUTS/OUTPUTS & ADJUSTABLE ATTENUATION】Equipped with a 6.35 mm (1/4\") TRS input and output, this DI box features an ATT switch with three attenuation levels (-0 dB, -20 dB, -40 dB), ensuring perfect compatibility with electric guitars, basses, keyboards, and other instruments with line output. 【SUPERIOR GROUND ISOLATION】With two balanced male XLR connectors with independent Ground Lift switches, it completely isolates input and output grounds – effectively eliminating hum, ground loops, and interference for clean, noise-free audio. 【MAXIMUM AUDIO CLARITY】Constructed from robust black metal (9.6 × 12.1 × 5.1 cm), this DI box minimizes noise, parasitic noise, distortion, and signal loss, preserving the original tonal integrity – ideal for live performances, studio recordings, or demanding rehearsals. 【PROFESSIONAL MULTI-INSTRUMENT USE】Perfectly suited for guitarists, bassists, keyboardists, and sound engineers, the DI-2 is an essential tool for connecting electric instruments directly to the microphone inputs of mixers, audio interfaces, or amplification systems – combining reliability, simplicity, and professional performance. Package includes: 1 passive DI box, 1 user manual.
