When Legend meets future. The 1073OPX Optional Digital card provides a USB and Dante AD/DA interface with eight channels of analogue to digital conversion for each 1073OPX preamp output and two channels of Digital to Analogue conversion for the digital monitor return signal path. The USB connection allows the 1073OPX to be connected to a DAW enabled PC/MAC computer to be used as a Primary/Core audio interface. In addition to the USB connection, Primary and Secondary Dante connections allow for the 1073OPX to be connected to any Dante Audio-Over-Ip network as a Dante enabled preamp. The Digital card can be retrofitted easily to any existing 1073OPX unit.
