User manual ART DUALXDIRECT

[. . . ] DUALXDirect Dual Channel Active Direct Box ARTcessories The DUALXDirect provides two independent high quality active interfaces that let you connect instrument, line, or speaker level signals to a mixer or other balanced inputs. Each of the high impedance 1/4" and XLR inputs (provided via "combo" jacks) are buffered and converted by very low noise active electronics into an isolated, balanced, low impedance signal output. [. . . ] When powered by a battery, it draws less than 7. 5 mA which should provide more than 100 hours of operation with a new battery (alkaline recommended). If phantom power is available, then the DUALXDirect will automatically draw its power from the external source. The POWER ON/OFF switch lights more dimly when the unit is running off of the battery, lights more brightly when it is running off of phantom power, and is off when the unit is inactive. The compact black-anodized all aluminum case and it's active design allow the DUALXDirect to provide years of trouble free service in Live Sound, Permanent/Fixed Install, D. J. , and virtually any PA application. It's full feature set, rugged construction, and high-end specifications make the DUALXDirect the obvious choice.

Connect one end of a phone jack cable to the corresponding THRU 1/4' TRS phone jack and the other end to where your signal was going to, if connecting the DUALXDirect inline in the signal path. Repeat for the other INPUT and THRU jacks if desired. Connect a balanced line cable between the corresponding OUTPUT 1 or 2 male XLR connector on the rear panel and the balanced inputs of your audio gear. If phantom power is not available, make sure a 9V battery is installed and push the POWER switch in to enable battery power. When using a battery for power, be sure to turn the POWER switch off when not using the unit in order to maximize battery life. [. . . ] Set the input ATTENUATOR switches for best signal strength and clarity. Select the GROUND LIFT feature to lower hum and other ground loop noise, if present. 2) 3) 4) [. . . ]
