Description
The POPE Professional® AM-401 active DI Box unit includes phantom power and battery supplies as standard. The unit is housed in a rugged steel extrusion case, with robust polyurethane end-cheeks which give the AM-401 a very distinctive look. Input connectors are both 1/4" jack sockets and an XLR socket, the latter meaning that the AM-401 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 AM-401 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 AM-401. For example, as well as the traditional guitar use, the AM-401 can be used with keyboards, DJ consoles, amplifier outputs, and other electronic sources. An additional bonus is the ability to use the AM-401 as an active balancing device.
