Master Clock
New Adelphi has a master clocking system. Devices can be clocked locally or synchronised to a high definition master clock which ensures every device receives the same timing pulse. This can be used to ensure a transmission 'lock' can be maintained between digital devices and is especially critical when working with audio for video content.
Hardware
New Adelphi uses an Antelope Isochrone Trinity master clock. This unit provides three audio clock outputs, three HD video clock outputs and four SD clock outputs.
The standard timings offered to the panel network are 44.1, 48 and 96kHz.
Using the Master Clock
In most cases the studio hardware is pre-wired to the master clock. Choosing 'Word Clock' from the clock source selector on compatible devices will synchronise that device with the timing pulse from the Trinity. The device should display the clock source rate it is receiving.
You will need to ensure that your session is configured to the same clock rate as that being received by the interface. Mismatched timings will result in clicks and pops on your recording, or your session may simply fail to play back.
The local interface has no control over the master clock timing rate; it is a slave device and your session must be configured to match.
