ProTools HD.
1.
The ADDA 2408 can be connected to ProTools HD system via ProTools 192 Digital I/O (without
ProTools converters) , or ProTools 192 I/O (with ProTools converters).
2.
Generally we recommend the ADDA 2408 as the master clock generator, because of its much more
accurate oscillators (5ppm) compared to most units. However the ADDA 2408 can be synchronized via
Word Clock and Super Clock as well.
3.
We recommend Word Clock instead of Super Clock where possible, because Super Clock is 256 times
faster than Word Clock and therefore more sensitive to Jitter.
4.
At 96 kHz it is necessary for the ADDA 2408 to be mounted with an 8 channel AES interface. Connect
this interface to the AES interface mounted in the ProTools system. You need a D-Sub break-out cable
from the ADDA 2408 and a D-Sub break -out cable from the ProTools HD. Some of the 8 channel AES
interfaces can be configured with the ProTools pinning at the D-Sub. In this case you can connect the
ADDA 2408 directly to the ProTools system with a normal 25 Pin D-Sub cable.
5.
It is also possibly to connect the ADDA 2408 to ProTools HD with a TDIF interface or a ProTools Mix 24
compatible interface, solely at 44.1 or 48 kHz. The ProTools Mix 24 compatible interface can be
connected to the legacy port on the ProTools HD system. Within the ProTools system the ADDA 2408
has to be set up as an 888/24.
