Great

Main highlights

•【Dual Independent Channel Signal Conversion for Pro Audio】 Featuring dual isolated channels, the DI-2 supports simultaneous connection of guitar/bass and keyboard/synth setups. Each channel offers 50KΩ high input impedance and balanced XLR output, eliminating high-Z signal distortion and cable noise—ideal for band performances, multi-track recording, and live streaming, boosting workflow efficiency by 50%.
•【Fully Balanced Signal Chain with Ground Noise Elimination】 Equipped with balanced XLR/TRS interfaces per channel for interference-free transmission. Independent ground switches tackle ground loop hum noise precisely, while -30dB pad function (marked "ATT") adapts to high-output devices, preventing clipping in real-time.
•【Intuitive Operation for Plug-and-Play Efficiency】 Top-panel signal flow indicators clarify channel status at a glance. Driver-free design connects directly to mixers, audio interfaces, or PA systems. The 6.2x3.9x2.5-inch compact chassis (1.32lbs) fits pedalboards or gig bags, enabling quick setup for live events.
•【Pro-Grade Sound Specifications | Isolated Dual-Channel Performance】 20Hz–20kHz full-range response (±1dB) captures detailed tones from deep lows to crisp highs; Ultra-low distortion (THD+N <0.03%) with 115dB high SNR preserves original signal dynamics; >85dB channel isolation eliminates crosstalk in dual-instrument recording, paired with 600Ω standard output impedance for seamless compatibility with mixers, audio interfaces, and PA systems.
•【StudioMan Industry Leader | Preferred Dual-Channel DI Solution】 We offer a one-year worry-free warranty and 24/7 technical support. Ninety percent of the problems are solved by email or chat within 12 hours. Free replacement of defective products.
