The ART Dual RDB is a passive 2-channel re-amping device and direct box. It provides the ideal solution for converting stereo or dual line-level signals (from audio interfaces, mixers, or consumer gear) to low-level XLR microphone or 1/4-inch instrument inputs. It utilizes high-quality isolation transformers to effectively break ground loops and ensure clean, transparent audio with a full 20Hz–20kHz frequency response.
