V6 User Manual 1.00.book - Studio General

Detailed notes and information :1. The table Bussing capabilities indicates the maximum channel count available in a Pyramix system in V4.xthrough V6.x modes:• HDTDM mode is the V4.x compatibility mode and offers the same PCM channels count as previously,except that DSD/DXD modes are no longer supported in this mode since V5.x.• XDTDM mode - V5.x and V6.x only - offers twice as many PCM and DSD/DXD channels comparedwith Pyramix V4.x.2. The greyed-out cells indicate that the corresponding mode does not exist for the corresponding daughtercards.3. DXD / DSD are only available in XDTDM and MassCore modes.4. In DXD mode, the I/O count depends on the I/O format speed.5. In DSD mode, I/O count depends on the AES I/O format (Sony or P3D respectively).6. Although the theoretical maximum DSD channel count with a MADI daughter card is 24, the bus capabilityhas a maximum of 16 DSD channels.7. The ADAT daughter card supports the XDTDM and MassCore modes ONLY with a hardware rework (shield).In XDTDM mode, the ADAT daughter card offers 8 output channels through optical output A) replicated onoptical output B) but No Inputs.The hardware rework consists of adding a shield to the ADAT similar to the one used for the DUAL daughtercard. If you have not already done so, please contact your Merging Sales Partner to order this retrofit kit.8. In a mono-board SDIF system, only 2 DSD channels are available.9. Dual offers 8 AES and 4 Analog channels of I/O per board.10. In standalone, non-Masscore mode only 8 channels DSD are available.Non-MassCore (Mykerinos mode) Multi-board hardware restrictions:The MADI 1 daughter card does not work in Multi-board mode (This includes all MADI daughter cards with serialnumbers lower than 30051).ADAT daughter cards with serial numbers lower than 20299 do not function in multi-board mode.The DUAL daughter cards do not function in multi-board mode.Appendix V Optional FeaturesPyramix DSD / SACDHardware and SettingsInterfacingDSD transmission works well with either AES-EBU or SDIF interfaces. Most converter manufacturers use SDIF. OnlydCS does SDIF and AES-EBU.A further issue is the existence of two different AES-EBU supported DSD formats. The so called "Sony" and onenamed "P3D." Merging Technologies support both of these. If you need to interface to both AES/EBU and SDIF twocards will be required.Wordclock settings.In DSD mode it is imperative Pyramix wordclock settings correspond with the requirements of the convertersemployed. To date all the DSD compatible converters we have tested generate and expect wordclock at the standardnominal rate. I.e. 44.1kHz.Failure to set Pyramix to expect only 44.1kHz in DSD operation will prevent proper locking to the external sourceand therefore prevent correct decoding of the DSD bitstreams, resulting in very loud noise on its outputs.
