The MX Active DI Box from BSS Audio uses an enhanced version of the same audio path, now regarded by many people as a reference standard. The sound quality is legendary, particularly on acoustic and bass guitars. Numerous applications can be satisfied by the DI Box. For example, as well as the traditional guitar use, the it can be used with keyboards, DJ consoles, amplifier outputs, and other electronic sources. An additional bonus is the ability to use the DI Box as an active balancing device. ??Input connectors are both 1/4" jack sockets and an XLR socket, the latter meaning that the DI Box can be used to convert unbalanced signals to a balanced output on XLRs throughout. The arched case allows cables to run back underneath the unit from the end for neat cable management. Input attenuation is 0, -20 or -40dB, making the box suitable for instrument, line or amplifier levels on inputs. On the output side, a ground-lift switch is provided for quick solutions to ground-loop problems. ??The DI box includes phantom power and battery supplies as standard. Should the phantom power from the console fail or be accidentally switched off, the DI Box automatically switches over to the internal 9V battery providing uninterrupted use. This unit is housed in a rugged aluminum extrusion case, with robust polyurethane end-cheeks which give the DI Box a very distinctive look.
