Technical Requirements
Video Sync Source
The Centuri Processor requires a feed of video sync. Other sources – MIDI or wordclock etc. – cannot be used as the sync reference.
The sync required is 75Ω
Many other studio peripherals (digital recorders, editors and all video picture recorders) will also require a feed of video sync. Depending on the studio configuration, a suitable video distribution amplifier may also be required.
Note : The Centuri processor does not provide internal sync generation.
Power Connections – Mains Input Voltage & Current
Both the console control surface and the Centuri processor rack are fitted with
The console is supplied with one or more detachable mains leads. These leads are 2m in length and the cable diameter is 11mm. The free ends of these leads are unterminated for connection to a suitable outlet.
The inrush current present when powering the console can be significant – typically ten times the steady current
– so the use of ‘slow’ or ‘motor’ rated
NetBridge (which is a separate 2U unit – see page 23) is fitted with a voltage select switch for 230V or 115V operation. Confirm that the voltage is correctly set before applying power – see page 23.
See Appendix A for equipment specifications.
Grounding
A standard system should not require any additional grounding over and above that supplied by a correctly installed mains supply. All rack unit chassis are permanently bonded to mains earth. A permanent mains earth connection via the mains inlet must be provided.
If, due to the quality of the mains wiring within an installation, it is deemed necessary to improve upon the mains earthing, chassis ground connection points are provided as follows:
Centuri rack chassis ground can be accessed via a stud located on the rear panel.
Console chassis ground can be accessed via a stud located on the mains power connector panel.
All audio connectors, both analogue and digital, have their screen pins connected directly to the chassis at the point of entry to comply with AES/EBU grounding and EMC standards.
