AES/EBU Hookup (PDI•8)
Cables & Hardware
(3) PDI•8 cards for HDR24/96
(3) PDI•8 cards for D8B
(1) Clock I/O card for D8B
(3) DB25 to DB25 AES/EBU snakes
(1) 75Ω BNC word clock cable
Hookup
1. Connect the three AES/EBU cables between the corresponding AES/EBU
connectors on the HDR24/96 and D8B.
2. When AES/EBU is used, the D8B must have a Clock I/O card installed. To
make the D8B the clock master, connect its Word Clock Out to the
HDR24/96 Word Clock In. To make the HDR24/96 the master, connect its
Word Clock Out to the D8B Word Clock In.
HDR24/96 Settings
1. If the HDR24/96 is the clock master, set the Sample Clock to Internal; if
it is a clock slave, set the Sample Clock to Word Clock and depress the
75Ω termination switch on the Sync card.
2. Set the Sample Rate to 44.1 kHz or 48 kHz according to your preference.
Console Settings
1. If the D8B is the clock master, set the Sample Clock to either 44.1 k
Internal or 48 k Internal; if it is a clock slave, set the Sample Clock to
either 44.1 kHz or 48 kHz. Set the sample rate to match the Sample Rate
selected on the HDR24/96.
OK, so we fibbed a little. You can use PDI•8 cards in the D8B without a Clock I/
O card installed, but doing so requires that you enable sample rate conversion
on both the D8B and the HDR24/96 in lieu of word clock synchronization.
Sample rate conversion results in a 4-bit loss in sample resolution that may de-
grade the quality of the sound slightly. So, the moral of the story is that unless
you just blew your wad on a new guitar and are eating peanut butter sand-
wiches until your next paycheck, go buy a Clock I/O card.
