Adjusting AES phase
The phase of the digital audio output may be adjusted with respect to the AES reference,
providing an AES reference is applied and the appropriate jumper link is set on the
DOP2-75 or DOP2-110 sub-board.
The AES output phase may be varied over a range of just over 360 degrees. The slider
readout display shows a reading of 0 to 127 for indication purposes only.
The AES output frequency is set by the frequency of the video signal carried by the SDI
signal. The AES output clock is synthesised at a fixed rate derived internally from the
TRS sync signals.
The AES reference input signal must be the same as that of the incoming video to be
useable, otherwise it will not work correctly. This is normally the case as the AES
reference signal and the embedded SDI audio data will have been locked to the station
master video source, so that the 48kHz sample rate and AES word rate are both
considered synchronous with the video signal.
Using the Toolkit
The Toolkit, accessed from the Audio Delay menu, provides comprehensive error
reporting and status information.
