BSS-AR133

BSS Audio AR-133 Active DI Box

The BSS Audio AR-133 is an active DI box. One of the toughest most versatile DI boxes on the market, the AR-133 is apt for guitars, keyboards, DJ rigs, instrument amplifier outputs and other electronic equipment - live or in the studio. The AR-133 offers 1/4" and XLR input connectors, and an XLR output. Ground switch, pad and link jack available too. 


    • BSS Audio AR-133 PRODUCT FEATURES:

      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.

      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 people as a reference standard. The sound quality is legendary, particularly on acoustic and bass guitars.

      An additional bonus is the ability to use the AR-133 as an active balancing device.
