Product Description
The unit comprises of battery supplies and phantom power as standard. In case the phantom power from the console fails or is accidently switched off, the internal 9V battery is applied. It is housed in a tough aluminum extrusion case, with robust polyurethane end- cheeks, which give the AR-133 a distinctive appearance. Input connectors are both 1/4" jack sockets and an XLR socket, which signifies that the AR-133 can be used to convert unbalanced signals to a balanced output on XLRs throughout.The case allows cables to run back underneath the unit from the end for neat cable management. Numerous applications can be satisfied by the AR-133. An additional facility is its usability as an active balancing device.
