OVERVIEW

Added functionality and enhanced audio performance for a price that won't break the bank.

The AR-133 Active DI Box from BSS Audio 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. 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. An additional bonus is the ability to use the AR-133 as an active balancing device.

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 BSS AR-133 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. This unit is housed in a rugged aluminum extrusion case, with robust polyurethane end-cheeks which give the AR-133 a very distinctive look.

Comments about BSS Audio AR-133 Active DI Box:

I did some research in this DI before i bought it and i am not dissappoint with my purchase at all.
It pretty covers what ever signal you need to a preamp input and it sounds great. Do your self a favor and do some research on this DI and i am pretty sure you would be disappointed also.
