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 aluminum 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.
