DI Box activ, 2 canal DB2A
Active 2-channel DI BOX that represents the solution for a long-distance transmission of stereo signals.

DB2A is an active 2-channel DI BOX that represents the most convenient solution for a long-distance, hum-free transmission of stereo signals.

For obtaining the best electronic performance, DB2A uses SMD components, low-noise IC for balancing the signals and differential inputs to eliminate typical ground-loop problems.

The complete set of connections and the PAD up to 30 dB allows any kind of source to be fed in. DB2A is particularly suited for the use with stereo keyboards, DJ equipment and PC-based audio systems.
