ARCHITECT'S AND ENGINEER'S SPECIFICATION
AR-133 ACTIVE DI BOX/LINE BALANCER

The Active Direct Inject box provides a transformer balanced and isolated feed from a source input via a 1/4' TRS jack or 3-pin XLR-type connector. Output is via an XLR connector. It also has a 1/4' TRS jack in parallel with the input for line bridging, which can be a direct feed or from an actively buffered input signal.

Power options include phantom power or a standard PP3 type 9 volt battery. An LED indicates power source - continuous for phantom, flashing every 2 seconds for battery.

Switches for EARTH LIFT, INPUT ATTENUATION, and Power On/Off are provided.

Housed in an aluminium extrusion with isolating side-cheeks, well-screened against external magnetic fields.

The Active DI box is the AR-133.
