Appendix 1
Recording AES Outputs 1-8 to Pro Tools ™ HD at 192kHz
To record all eight channels digitally to Pro Tools™ HD at 192kHz, all eight AES channels need to be enabled on the ISA
828 (default jumper positions shown on Appendix 2) and 2 Digital cards must be fitted in the HD192 interface. A 25-pin to
two 25-pin cable must then be used, with the following pinout:
