HAPI MKII User Manual
Warning: The Auto sampling Rate option must be disabled if locking the
Horus/Hapi devices to reference (e.g. 44.1kHz WordClock) which would be
different than the working Sampling Rate Format (E.g. 88.2kHz,,192kHz, DXD.)
For MADI, the Auto sampling rate option depends on the MADI framing (48 or
96k frame). Therefore it is recommended to disable the option at sampling
rates higher than 48 kHz.
A/D Mode in DXD/DSD: This format setup only applies to the AD module which can be set to either
DXD - DSD64 - DSD128 - DSD256
Note: The Hapi can be configured in DXD/DSD and in this mode the Hapi can
receive any audio data format stream and can generate DXD or DSD(64, 128
or 256) stream depending on the A/D audio data format chosen.
WordClock Output:
44k1 / 48k: When enabled the Wordclock Output will be at either 44.1kHz or
48kHz
Example:
Sampling Rate: 44k1/88k2/176k4 the WordClock Output will be 44.1kHz
Sampling Rate: 44k/96k/192k the WordClock Output will be 48kHz.
Follow SR: When enabled the WordClock Ouput will follow the Sampling Rate
selected.
Example:
If the selected Sampling Rate is 48k the WordClock output will be at 48kHz
If the selected Sampling Rate is 176k4 the WordClock output will be 176.4kHz
Pull Up/Down: Slow down or accelerate audio clock by 0.1 % depending of the frame rate of
the video reference.
This option will only be active if the sync source is configured to Video Ref.
The Status of this option can be viewed in the IO&Sync page under Status
- Off: Normal operating mode
- Up: Accelerate the clock by 0.1%. Supported only with a Video reference at
24fps and 30fps
- Down: Slowdown the clock by 0.1%. Supported only with a Video reference at
23.98fps and 29.97fps
