1. The four red LEDs 4 0 1 0 1 4 indicate selected pull up pull down factors These sample rates are only used for special audio video and film transfers They should be off in normal operation at 48 000 or 44 100 kHz 4 Output Multiplier LEDs Each of the six word clock outputs is individually configurable The first three can be either the basic sampling rate 44 1 48kHz or x2 88 2 96kHz and the second three basic sampling rates or x256 Digidesign Super Clock The six yellow LEDs indicate the selected multipliers 5 Setup Keys Pressing the MENU key enters setup mode the blinking LED indicates the current selected reference source Subsequent depressions of the MENU key select the parameter to change Reference Source Base Sample Rate Pull up Pull down Wordclock frequency multiplier Depressing the SELECT key cycles through the options for each selected parameter Once the desired parameters are set pressing and holding the MENU key for approximately one second until the LEDs stops blinking stores the set up in non volatile memory For a temporary set up stay in setup mode Turning of the unit when in setup mode and then re powering the unit will re set the previously stored parameters See also chapter Unit Operation for more details 3 Back Panel oO OQU H VIDEO OUTPUTS REFERENCE INPUTS a 2 S z vo1 Vo2 VO3 Vog VIDEO WORD SPDIF HE CEL BLACK amp BUR2.
