INTRODUCTION

The name DI box comes from direct injection box, that means exactly: To inject a signal directly or take an audio

signal from the source and send it directly to a mixer console or recorder. Direct boxes perform several important

functions: they are designed as impedance matching and signal balancing devices. This means that they take the

high impedance of a guitar or keyboard and ‘transform’ it to the low impedance used in balanced sound systems.

Balanced signals inherently cancel noise and, due to their lower impedance, are capable of very long cable runs.

Balanced signals are the norm in professional recording, broadcast and live sound. By properly matching the

impedance you will enjoy better sound, less noise and an extended frequency response.

DB1-A is an active direct box with an isolation transformer. This means that it includes a powered circuit to convert

the impedance and balance the signal and, with the isolation transformer, a full isolation from grounds avoiding

hum and buzz problems.

The moulded sides make stacking of multiple units easier, and help isolate the case of the DI-box from the stage

both electrically and mechanically. The DB1-A derives its power from the mixing console phantom power, from a

battery or from an external AC/DC adaptor.
