Product Description
BSS BSSAR133 Active Direct Box / Line Balancer
Overview
A comprehensive DI box with line balancing functionality and legendary sound.
With added functionality and enhanced audio performance, the AR-133 Active DI Box/Line Balancer has been designed to be more affordable for musicians, studios, and live sound providers. 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 for 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. 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. 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 AR-133 uses an enhanced version of the same audio path as the AR-116, now regarded by many as a reference standard. The sound quality is legendary, particularly on acoustic and bass guitars. The AR-133 can be used with keyboards, DJ consoles, amplifier outputs, and other electronic sources.
