About the 400X
The DBX 400X is a versatile audio routing device that allows users to connect and manage multiple audio sources, including up to three decks, three sound processors, and a noise reduction unit. It provides a flexible way to route audio signals through various processors before recording or playback, making it ideal for complex HiFi systems. The 400X does not require external power, as it operates passively, connecting directly to the tape monitor loop of a preamp, receiver, or integrated amplifier. This feature helps maintain signal integrity without adding noise or distortion.
