Description

The AR-133 Active DI Box from BSS Audio uses an enhanced version of the same audio path as the AR-116, regarded by many as a reference standard.

The sound quality is legendary, particularly on acoustic and bass guitars. Numerous applications can be satisfied by the AR-133. As well as the traditional guitar use, the AR-133 can be used with keyboards, DJ consoles, amplifier outputs, and other electronic sources. An additional bonus is the ability to use the AR-133 as an active balancing device. 

The 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.

  • Switchable input attenuation
