1. Synchronisation The SDI MADI offers a choice of wordclock synchronisation sources The selection is made from the front panel and the array of LEDs confirms the currently selected source The selected source is used as reference for all four output SRCs thus ALL audio outputs both in AES3 and MADI formats will be locked to the selected reference The various clock sources are discussed on the following page Synchronisation Sync To Wordclock SRC sync to an external wordclock is indicated by illumination of the WK front panel LED The clock source should be connected to the SYNC IN connector a BNC socket on the rear panel Nominal frequency is 48 kHz 5oppm and clock pulses should be of 5 V amplitude positive going Sync To Video Black And Burst The SDI MADI can also synchronise to a standard SD 1 V black and burst video signal The video signal should be connected to the SYNC IN connector on the rear panel The sync input auto detects NTSC or PAL standard video Sync To AES3 An AES3 compliant digital audio source may be used as the clock reference source The internal 48 kHz wordclock source is phase locked to the incoming AES3 signal Any audio data contained in the AES3 word will be ignored The audio source should be compliant with AES3 4 2009 Annex D for 75 Q coaxial transmission and connected to the SYNC IN connector on the rear panel Sync To The SDI Inputs Any of the four SDI inputs may be used to reference the audio o2. www solid state logic com XLogic SDI MADI Installation and User Guide SR OCK e e se e e e e iDIGATION 66 eS AA REE 2 7 z NA Si e Solid State Logic This is SSL SOUND VISION Important Safety and Installation Instructions This section contains definitions warnings and practical information to ensure a safe working environment Please take time to read this section before installing or using this unit Please do not dispose of these instructions lt Read these instructions lt Keep these instructions lt Heed all warnings lt Follow all instructions lt Do not use this apparatus near water lt Do not expose this apparatus to rain or moisture lt Clean only with a dry cloth lt Do not block any ventilation openings Install with accordance with the manufacturer s instructions lt No naked flames such as lighted candles should be placed on the apparatus lt Do not install near any heat sources such as radiators heat registers stoves or other apparatus including amplifiers that produce heat lt There are no user adjustments or user serviceable items inside this apparatus Do not remove the covers of this apparatus doing so will invalidate your warranty lt Adjustments or alterations to this apparatus may affect the performance such that safety and or international compliance standards may no longer be met lt Refer all servicing to qualified service per
