dbx AR-133 Active DI Box Details

dbx AR-133 Active DI Box provides a transformer balanced and isolated feed from a source input via a 1/4" TRS jack or 3-pin XLR-type connector. The output of dbx AR-133 Active DI Box is taken via an XLR connector. dbx AR-133 Active DI Box also provides a 1/4" TRS jack in parallel with the input to act as a link for line bridging. The link is a direct feed from the input, or it is optionally fed from an actively buffered input signal. dbx AR-133 Active DI Box is powered either via a phantom power source, or via a standard PP3 type 9 volt battery. An LED illuminates continuously to show power is provided by a phantom source, or flash approximately every 2 seconds if powered by the battery. Switches are: EARTH LIFT (output pin 1 disconnected from unit ground), INPUT ATTENUATION (of 0, 20 or 40dB), and Power On/Off. dbx AR-133 Active DI Box is housed in an aluminium extrusion fitted with isolating side-cheeks and sufficiently screened so it is not susceptible to external magnetic fields.

dbx AR-133 Active DI Box Features

  • The phantom power and 9V battery ensures the continuous function of dbx AR-133 Active DI Box. When phantom power goes off, the box automatically shifts on battery
  • Housed in a rugged aluminium extrusion case, with robust polyurethane end-cheeks which give the box 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 sound quality is legendary, particularly on acoustic and bass guitars
  • Using with the traditional guitar, AR-133 can be used with keyboards, DJ consoles, amplifier outputs, and other electronic sources
