The Lectrosonics DBu is a fourth-generation digital UHF beltpack transmitter built for professional wireless audio applications where security, audio quality, and RF flexibility are non-negotiable. It is designed for touring engineers, broadcast crews, corporate AV integrators, and government or high-security production environments that require encrypted RF links without compromising audio performance.
Pure digital architecture at 24-bit/48 kHz delivers studio-quality audio across any lavaliere, dynamic, or line-level source. The 44 dB input gain range adjustable in 1 dB steps lets engineers dial in an exact match to the source signal, maximizing dynamic range and signal-to-noise ratio. DSP-controlled limiting with a 30 dB range handles transients cleanly, and bicolor LED modulation indicators plus a backlit LCD give real-time level feedback without guesswork on set or on stage.
Selectable RF output at 10, 25, or 50 mW and coarse-to-fine tuning across the full UHF television band give RF coordinators the flexibility to manage complex multichannel deployments in congested spectrum environments. The solid machined aluminum body with electroless nickel finish withstands the physical demands of daily production use. A USB port supports firmware updates in the field, and an IR port enables fast receiver-to-transmitter setup without navigating menus manually.
