BSS Audio AR133 Active DI box.

With added functionality and enhanced audio performance, the AR-133 has been designed to be more affordable for musicians, studios and PA companies. The unit includes phantom power and battery supplies as standard. Should the phantom power from the console fail or be accidentally switched off, the AR-133 automatically switches over to the internal 9V battery providing uninterrupted use. The unit is housed in a rugged aluminium extrusion case, with robust polyurethane end-cheeks which give the AR-133 a very distinctive look.nbsp Input connectors are both 1/4" jack sockets and an XLR socket, the latter meaning that the AR-133 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.nbsp Input attenuation is 0, -20 or -40dB, making the box suitable for instrument,nbsp line or amplifier levels on inputs. On the output side, a ground-lift switch is provided for quick solutions to ground-loop problems.nbsp The AR-133 uses an enhanced version of the same audio path as the AR-116, now regarded by many people as a reference standard. The sound quality is legendary, particularly on acoustic and bass guitars.nbsp Numerous applications can be satisfied by the AR-133. For example, as well as the traditional guitar use, the AR-133 can be used with keyboards, DJ consoles, amplifier outputs, and other electronic sources.
