WordClock
At this point the connection mode has been set, and you should have returned the Alpha-Link to normal operation by
e
xiting diagnostics mode. You can move on to the clock and routing settings.
External Clock Source
I
f you have connected your Alpha-Links according to our connection diagram using an external clock
master device, both Alpha-Links are synchronized to an external source:
• The external clock source must be set to provide a 44.1 or 48kHz clock signal (as required for the
c
onfiguration in this example)
• Alpha-Link 1 receives the reference clock signal from the clock master device
• Alpha-Link 2 receives the clock signal from Alpha-Link 1
Both Alpha-Links therefore need to be set to ‘External’. To do this, simply press the CLOCK button
repeatedly until the EXT LED is lit.
This must be done on both Alpha-Links
Internal Clock Source
If you have chosen to use Alpha-Link 1 as a clock source for Alpha-Link 2 (typically, if you do not have a dedicated master
clock device):
• Alpha-Link 1 must be set to ‘Internal’ to lock to its on-board clock generator
• Alpha-Link 1 must also be set to 44.1 or 48kHz by pressing the SAMPLE RATE button (as required for the
configuration in this example)
• Alpha-Link 2 will receive the clock signal from Alpha-Link 1
Press the Alpha-Link 1 CLOCK button repeatedly until the INT LED is lit, then press the Alpha-Link 2 CLOCK button
repeatedly until the EXT LED is lit.
