SD Rack 1.2 SD Rack Power The SD rack has dual redundant hot swappable power supplies. The rack should be operated with both powersupplies on whenever possible. 1.3 SD Rack Clocking The SD Rack will receive clock sync from the connected console in normal operation. It can run run at 48KHz or 96khz when clocked by the console. It is capable of running at 192KHz but this has not yet been implemented in current console software.
SD Rack 1.4.1 Analogue Mic/Line Input card (ADC) .................................. The 8 Mic/Line input ADC card has 2 indicators on each socket. The orange indicator shows the status of +48V Phantom Power On/Off. The green indicator shows signal present and this turns red when the signal is close to clipping. 1.4.2 Analogue Line Output card (DAC) ...................................... The 8 Line output DAC card has 2 indicators at the bottom of the card.
SD Rack 1.6 Using the SD Rack Menu System The LCD Menu System on the rack MADIPod is normally in a locked state and cannot be accessed. The main display will be visible and if the rack is not connected to an SD console the background colour will be light blue. If an SD console is connected and the rack is correctly receiving control data from it, the display will flash green. Pressing and holding the 2 buttons marked with left and right arrows for 2 seconds unlocks the Menu System.

SD Rack 1.6.1 PSU Readings....................................................................... This page shows readings for all rack PSU voltages. No adjustment is possible from the menu. 1.6.2 I/O Card Code Versions ....................................................... This page shows the type of card detected in each rack slot and the firmware version installed on the card. SLx indicates slot number in the range SL1 to SL14 reading left to right in the rack. Date codes are DD/MM/YY.
SD Rack 1.6.7 Optocore ID & Fibre Speed ................................................. These pages show the Optocore ID of the rack in range of 11 to 24 and the fibre speed which is either 1GB or 2 GB. Each rack requires a unique ID so that it can be recognised by the rest of the Optocore system. To change the ID, scroll with the Left/ Right buttons until you reach the required number. The rack fibre speed needs to be set to the same value as all other devices in the Optocore system.
SD Rack 1.6.11 Rack Sample Rate .............................................................. This page allows selection of the rack sample rate. This is only possible if the Rack Sync Source is set to internal. Available options are 44.1KHz, 48KHz, 88.2KHz, 96KHz, 176KHz and 192KHz 1.6.12 Rack Routing Mode ........................................................... This page allows selection of the rack routing mode - which external source (MADI or Optocore) is being routed in and out of the rack.
SD Rack 1.6.14 Rack Main and Aux Splits ................................................. This page controls the Main (MadiSM) and Aux (MadiSX) MADI Split functions. 1) Each split can be < OFF >, < ON > or ON with automatic Gain Tracking enabled (< GT >). 2) The sample rate of the split signal can also be set to be either the same as the rack's current sample rate < SYS > eg 96Khz or < SYS/2 > which is half of the rack's current sample rate. eg Rack at 96KHz and split at 48KHz.
