1. X Rack Master Module El Note 2 E3 E3 1 The Master Module Introduction Used in conjunction with the XR623 X Rack Line Return module the XR622 X Rack Master module provides a complete small scale mix and monitor system for studios seeking a compact solution for mixing and monitoring in the analogue domain A single X Rack can provide up to 28 line level inputs Additional racks can be connected via the MIX BUS LINK connector on the rear of the X Rack unit allowing additional inputs to be added to the system if required X Rack units prior to serial number XRKO110 are not equipped with a MIX BUS LINK connector The X Rack Total Recall system allows session setups to be recalled instantly and can be archived as a MIDI SysEx dump to any MIDI sequencer The monitor section controls can also be controlled remotely using MIDI controller commands from any MIDI controller Up to three racks can be connected to an AWS 900 or AWS 900 and integrated with the AWS 900 Total Recall system via the serial port Connecting the MIX and REC outputs of the XR 622 to the MIX and REC Insert Returns of the AWS 900 and selecting INSERT SUM mode allows almost unlimited expansion of the number of line level inputs to the console Connection The rear panel of the module carries a pair of 25 way D connectors The left hand INSRTN INS SND EXT MIX connector provides the main and alternate Monitor outputs as well as a stereo Externa2. 8 Physical Specification Depth 200mm 7 9 inches including front panel knobs excluding connectors 275mm 10 9 inches including front panel knobs and connectors Height 171mm 6 75 inches Width 35mm 1 4 inches front rear panels 49mm 1 9 inches overall width front and rear panels are offset Weight 260g 9 5 ounces Boxed size 190mm x 290mm x 70mm 7 5 x 11 5 x 2 5 Boxed weight 460g 16 5 ounces All values are approximate Environmental Specification As per X Rack see page 19 Page F 7 X Rack Owner s Manual Page F 8
