Connect your computer, mobile device, DJ mixer, or keyboard directly to your preferred mic preamps with the On-Stage DB2050 active stereo multimedia DI box. It adapts high-impedance, line-level signals from the 1/4" TS, 3.5mm TRS, or RCA coaxial input jacks to two low-impedance, mic-level, isolated XLR outputs. By converting your signal from unbalanced to balanced, it allows longer cable runs, less noise, and proper compatibility with mic inputs.Parallel inputs and dedicated RCA thru jacks provide an unbalanced pass-through for easy connection to a personal mixer or secondary recorder. Flip the -15 dB pad switch to prevent distortion when accepting high-output sources, and utilize the ground-lift switch to rid your signal of hum from ground loops. Since the DB2050 is a phantom-powered direct box, no batteries, power cables, or AC adapters are required. It features a durable metal housing with protective nylon bumpers, making it equally well suited for constant use in the studio, on stage, or at home.
