M-AUDIO DELTA 66 - Manual (Page 21)

2. The second option, “Monitor Mixer,” connects the S/PDIF Out port to the
outputs of the Delta 66 monitor mixer. For more information on the capabilities
of the monitor mixer, please see the section “Monitor Mixer Page.”
3. The third option, “S/PDIF In,” connects the S/PDIF Out port directly to the
hardware S/PDIF input on the Delta 66 PCI host card. The left channel of the
S/PDIF In is routed to the left channel of S/PDIF Out and the right channel of
the S/PDIF In is routed to the right channel of S/PDIF Out.
4. The fourth option, “S/PDIF In (L/R Rev.),” functions identically to the third
option, except that the left and right channels are swapped. Therefore in this
mode, the left channel of the S/PDIF In is routed to the right channel of S/PDIF
Out and the right channel of the S/PDIF In is routed to the left channel of
S/PDIF Out.
5. Selections five and six connect the hardware analog inputs 1 & 2 or 3 & 4
(respectively) directly to the Delta 66’s S/PDIF Out port. For example, if “H/W
In 1/2” were selected, any signal present at the IN1 port will be sent to the left
channel of the S/PDIF Out, and any signal present at the IN2 port will be sent
to the right channel of the S/PDIF Out. This same behavior applies to “H/W In
3/4” when selected.
At this point, you may begin to realize the versatility of the Monitor Mixer and the
Patchbay/Router, and the relationship between the two. You may want to re-read this
section and make some practice adjustments within the Delta Control Panel software
to become proficient in routing and mixing. If somewhere in the process you
become confused, you may always restore the default settings to use the card as a
straight 6-in 6-out device — just choose the topmost option in each of the
Patchbay/Router columns.
Hardware Settings Page
The Hardware Settings page of the Delta Control Panel gives you control over
miscellaneous features of the Delta 66. To display this page, click the “Hardware
Settings” tab of the Delta Control Panel.
MASTER CLOCK: This section allows you to select the source of the board’s
master clock: Internal Xtal (crystal) or S/PDIF In. Master clock operation is outlined
in the Synchronization section of this manual. Internal Xtal is the default setting. Be
sure to select “S/PDIF In” if you will be recording or monitoring an S/PDIF stream.
NOTE: If “S/PDIF In” is selected as the master clock source, be
sure to supply a valid S/PDIF signal to the board’s active S/PDIF
input. Otherwise, erratic timing and/or improper sample rates
will be experienced.
