A sync reference needs to be provided for the system to function correctly when connected to external digital equipment.
If the generator does not provided multiple buffered outputs then a separate distribution amplifier will also be needed.
• Recommended source of sync is: 3'14-:+;/*+4(1Vp-p, SD
NOTE 1
, PAL, NTSC, Composite, B&B). Alternative sources
are $47*)14)0 or /*. See Appendix page 4-16 for a list of supported sync rates.
• Sync is required by each Blackrock processor. Systems that feature processor redundancy will require two separate
sync feeds, one to each processor – sync should not be daisy-chained between units.
• Sync is required by each Alpha-Link LIVE-R I/O unit
NOTE 2
.
• Sync will be required by a MORSE router.
NOTE 1
– The Blackrock processor is also able to accept
HD
and
Tri-level
sync reference signals. However, the Alpha-Link LIVE
and MORSE units cannot accept HD sync signals so a source of SD sync will still be a requirement.
NOTE 2
– Remotely located Alpha-Link LIVE units may optionally be configured to use their incoming MADI signal as the sync
reference. Note however, that when operating in this mode, the inherent nature of the MADI signal means there will be a
degradation of jitter performance and redundant-processor systems may experience a slight delay and/or drop of audio if it
becomes necessary to re-reference to the backup MADI stream.

All units will require a supply of mains power. Supply requirements are 100–230V±10%, 50–60Hz, AC only.
All inlets use detachable IEC-type mains leads. The leads supplied are 2m in length. The free end of each lead is
unterminated and will need to be connected to a suitable nearby outlet – the ground wire must always be connected.
C100 HDS systems feature dual-redundant power supplies as standard and are therefore fitted with two separate IEC
mains input connectors. (See note on UPS provision below).
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 fuses or circuit-breakers is recommended.
Power ratings are listed in the Specifications appendix page 4-2 and on a rating label adjacent to each input connector.

Where either supply of mains power is provided from an uninterruptable source (UPS) the output waveform of the UPS
equipment must be of the sinusoidal variety. Switched or stepped output waveforms may cause damage to the console
power supplies so must not be used.
"%
A standard system should not require any additional grounding over and above that supplied by a correctly installed mains
supply. The chassis of the console and the audio I/O boxes is permanently bonded to the mains earth pin*. A mains earth
connection via the mains inlet must be provided.
* The optional remote GPIO unit is an exception as it does have an isolated chassis. If specified, its case must be separately
grounded using the earth stud provided on its rear panel. Refer to pages 2-29 and 3-21.
All audio connectors, analogue and digital, have their screen pins connected directly to the chassis at the point of entry
to comply with AES/EBU EMC grounding standards.
