RapcoHorizon DB-2 Passive Dual-Channel Direct Box

The RapcoHorizon DB-2 is a passive dual direct box built for working engineers and touring musicians who need a compact, no-fuss solution for converting instrument-level signals to balanced mic-level outputs. With two fully independent channels sharing a single housing, it handles stereo sources, keyboard rigs, or two separate instruments simultaneously without requiring batteries or phantom power — a reliable choice when rack space, weight, and power availability are all concerns.

Each channel routes signal through a DBT transformer and delivers a balanced XLR male output for direct connection to any mixing console mic input. A quarter-inch loop-through jack on each channel keeps the original signal path intact for monitoring or feeding a stage amplifier, making the DB-2 well-suited for live stage applications where the performer still needs an amp on deck. The panel-mount ground lift switches on both channels address hum and buzz introduced by ground loops — a common issue in venues with aging electrical infrastructure or when sharing power with lighting rigs.

For audio engineers running front-of-house at small-to-mid-size venues, sound companies managing backline, or AV integrators handling presentation audio, the DB-2 offers a straightforward transformer-isolated interface that performs consistently across a wide range of source signals without the maintenance overhead of active designs.
