Clock Source
One of the most important settings on the X-48 is the sample clock source, which governs
playback speed and keeps audio pops from happening. There are five choices:
•
Internal is the default. This can be used if the X-48 is either used by itself, with an
analog console or as the master clock for the studio.
• Word Clock should be used when you have an external, dedicated master clock
available. The word clock generator needs to be set to the same sample rate as the X-
48. (Note: the Word Clock input can accept a tri-phase signal from HDTV devices.)
• S/PDIF clocks the X-48 from the digital audio signal coming into the S/PDIF Digital
Input.
• TDIF Port 1 clocks the X-48 from the digital audio signal coming into the TDIF
Digital Input channels 1-8.
• If you have digital audio option cards installed (IF-AD24(X) / IF-AE24(X) ), those
will show up as an available clock source as 'ADAT Card' / 'AES/EBU Card'.
When in doubt, use Word Clock as the reference source. To change the clock source:

BNC Clock In/BNC Clock Out
These parameters allow the word clock signal input or output to be multiplied or divided by
2, or used as-is. This allows, for example, a 48kHz word clock generator to be used when
recording at 96kHz, or allows 48k and 96k devices to be used at the same time. To change
these settings:
