Either: do this: connect the Master Clock to the AES CLK Input and select AES as the Sync Source, or: do this: connect the Master Clock to the SDIF-2 CLK Input and select Word Clock as the Sync Source. Since the Output Frequency of the dCS 972 is different to the Master Clock frequency, the DAC would be unable to lock to the data from the dCS 972 if it were sync'ed to the Master Clock. So, slave the DAC to the dCS 972, NOT to the Master Clock. IMPORTANT!

For all units, set the Multi-channel Sync option to On. The top unit will set up as a master, the other ones will set up as slaves. Make sure that all the other settings are the same on each unit. See section Multiple Channel Sync'ing, page 68 for how aligned is bit aligned. These are set up, for PCM in to DSD out, in Store 11, and for PCM in to 96 kS/s out in Store 12, by dCS. You can overwrite them.

The sync link cabling starts from the master clock (cable "A") and then carries on down units as shown. Use of the master clock allows more units to be used together ­ 24 channels worth or more. For all dCS 972 units, set the Multichannel Sync option to On. Make sure that all the other settings are the same on each unit. 13 13 version 2. 0 or higher software Manual part no: DOC1241102C2 Contact dCS on + 44 1799 531 999 Page 53 Remote Document No: OS-MA-A0124-110. 2C2 (inside the UK replace + 44 with 0) email to: more@dcsltd. co. uk web site: www. dcsltd. co. uk dCS 972 User Manual dCS Ltd Manual for Software Version 2. 3x January 2001 Multi-channel Sample Rate Conversion ­ with more alignment tolerance WORDCLOCKS TO SOURCES AES 1 more@dcsltd. co. uk AES 2 AES 3 AES 4 1 2 3 4 5 6 In Mains Fuse (2AT) On Off W ordclock Outputs AES/EBU Outputs 7 8 9 10 11 12 External Sync Loop Out Remote A AES1 PUSH C AES2 PUSH dCS 992 Master Clock AES2 AES CLK In Rem ote 96kS/s Ch1 & 2 AES CLK PUSH AES1 SDIF-2 Inputs CH1 CH2 CLK AES / EBU Inputs AES / EBU Outputs Out MAINS FUSE 2A(T) ON OFF SDIF-2 Outputs SPDIF Outputs SPDIF Inputs FROM SOURCE SPDIF1 SPDIF2 SPDIF3 SYNC IN CH1 CH2 CLK 96kS/s Ch3 & 4 AES1 PUSH AES2 PUSH AES CLK PUSH AES1 SDIF-2 Inputs CH1 CH2 CLK AES2 AES CLK In Rem ote MAINS FUSE 2A(T) ON AES / EBU Inputs AES / EBU Outputs Out OFF SPDIF1 SPDIF Inputs SPDIF2 SPDIF3 SYNC IN CH1 CH2 CLK SPDIF Outputs SDIF-2 Outputs 96kS/s Ch5 & 6 AES1 PUSH AES2 PUSH AES CLK PUSH AES1 SDIF-2 Inputs CH1 CH2 CLK AES2 AES CLK In Rem ote MAINS FUSE 2A(T) ON AES / EBU Inputs AES / EBU Outputs Out OFF SDIF-2 Outputs SPDIF Outputs SPDIF Inputs FROM SOURCE SPDIF1 SPDIF2 SPDIF3 SYNC IN CH1 CH2 CLK 96kS/s Ch7 & 8 AES1 PUSH AES2 PUSH AES CLK PUSH AES1 SDIF-2 Inputs CH1 CH2 CLK AES2 AES CLK In Rem ote AES / EBU Inputs AES / EBU Outputs Out SPDIF3 CH2 CLK Figure 11 ­ Multi-channel Sample Rate Conversion with more alignment tolerance A dCS 992 Master Clock can also be used to sync up the source and the dCS 972 units as above. In addition to the sync link cabling (starting with "A"), additional clocking (cables "C") allow the dCS 972's to extract clocks from the "C" cables and extract the data from the signal input cables. The master clock outputs different frequencies on the different cabling types. This allows considerable bit alignment error, as might occur if some tracks are stored on one machine and some on another. For all dCS 972 units, set the Multi-channel Sync option to On.
