di1 DIRECT BOX Overview Introduction Congratulations on purchasing the dbx di1 Active Direct Box. Ideal for both studios and on the road, the di1 will ensure audio signals reach their intended destination free from unwanted noise and in a balanced format. The di1 provides a range of features such as level and impedance matching, phantom power indication, signal pass through, and ground lift functionality. The di1’s versatility makes it suitable for a wide range of applications.
di1 DIRECT BOX Using a Direct Box First, a direct box converts the audio signal originating from an unbalanced device (like a guitar) to a balanced audio signal for transmission over a longer distance than is recommended for an unbalanced signal to travel. As audio industry people know, the advantage of a balanced signal is realized at the receiving end (audio input) of the balanced cable, typically in the form of a mic pre-amp input on a mixing console.

di1 DIRECT BOX Application & Operation Battery Power & Installation The di1 operates using a standard 9V battery (not included) or phantom power. There is a secured battery compartment housed within the di1 with access provided through a removable metal compartment cover. Simply unscrew the battery compartment cover to gain access to the battery compartment for battery installation or replacement of expired batteries.
di1 DIRECT BOX Controls Attenuation Switch The attenuation switch allows an incoming source signal to be attenuated by 20 dB or 40 dB. This is useful for operation with very hot signals that would otherwise overload the di1. Ground Lift Switch The Ground lift switch enables or disables continuous connection of the input and output ground connection. This is useful for helping to eliminate ground loop hum problems that can arise between connected devices.
