Rolls DB24 — passive stereo DI box with dual RCA and 1/4-inch jack inputs for converting unbalanced consumer or instrument signals to balanced XLR outputs. The DB24 accepts stereo input via two RCA connectors or two 1/4-inch jacks and converts each channel via transformer isolation to a balanced XLR output for professional mixing or PA equipment. The dual-input format accommodates both consumer line sources (CD players, laptops, phones) and instrument-level sources (keyboards, synths) without adapters. Passive construction requires no power. A ground lift switch helps eliminate hum from ground loops common when connecting consumer electronics to professional audio systems.
