Sync - Solid State Logic C10 HD Installation Manual

System Menu

Sync

The Sync pop-up indicates what reference source is being used to lock the audio sample rate and define the frame rate.
the following reference source options are available:
internal
•
• SD Video (PAL or NTSC 'black and burst'), and HD Video (Tri-Level Sync)
• Unbalanced AeS (AESiD)
• word clock (Fs).
If there is no suitable incoming reference signal for either the audio sample or frame rate, the console will automatically
generate its own PAL clock signal. The external sources will be greyed out in the pop-up's list, and both of the internal
sync lights will be lit.
If there is a suitable incoming reference signal, the console will automatically
lock to it. The external reference source will lighten in the pop-up's list, and
its Audio sync light will be green.
If this reference does not define the frame rate (i.e. if it is an AES or Word
Clock signal), the frame rate defaults to PAL, as indicated by the internal
(PAL) / Frame sync light being lit.
The full list of compatible sync sources is as follows:
PAL
PAL 24
NTSC
1080i 60Hz
1080i 59.94Hz
Note: To lock properly to an external clock, you must provide a valid reference signal, which must be equal to the
chosen sample rate (Fs) and be stable within ±50ppm.
Note that C10 is AES11 Compliant, with the exception of the following:
The console supports consistent phase locking of AES-3 outputs to a PAL video reference signal, thus ensuring
consistent latency through connected AES-3 devices. Connecting video sync to the Blackrock Sync input and
selecting Video as a reference will automatically enable this.
Phase lock to an NTSC video signal is not supported as the Blackrock processor does not support decoding of the
NTSC 5 field sequence. Clients who wish to take advantage of this feature in an NTSC environment will need to
carry out FSB884 on their Blackrock processor cards and connect an AES-3 DARS from a sync generator that
supports decoding of the 5 field sequence.

If the video input is the selected external reference source, it also defines
the console's frame rate, as indicated by Video lightening in the pop-up's
list and both of its sync lights being lit.
The Video and internal legends will also display the frame rate for HD and
SD Video sources.
