[. . . ] All of these signal paths have adjustable level, pan, solo, and mute controls as set up in the Monitor Mixer page of the control panel software. The third selection, "S/PDIF In", connects the S/PDIF input (the one currently selected as the active S/PDIF input) to the S/PDIF outputs. The final option, "S/PDIF In (L/R Rev. )", functions identically to the third selection, except that the left and right channels are swapped. 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 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 2in 4-out device. Hardware Settings Page The Hardware Settings page of the Delta Control Panel gives you control over miscellaneous hardware and software features of the Delta DiO. To display this page, click the "Hardware Settings" tab of the Delta Control Panel. MASTER CLOCK: This section allows you to select the board's master clock source: Internal Xtal (crystal) or S/PDIF In. Master clock operation is outlined in the Synchronization section of this manual. 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 improper sample rates will be experienced. Once a master clock source has been selected, its synchronization status is continually monitored and displayed below the master clock radio buttons. If internal crystal is selected, the status display will always say "Locked. " On the other hand, if S/PDIF In is selected as the master clock source, the control panel will display "Locked" only when a valid S/PDIF signal is detected. It will display "Unlocked" when there is no signal at the selected input, or when the signal is corrupt or has become degraded for any reason. 12 CODEC SAMPLE RATE: This section is enabled only when the board is set to use the internal crystal (Internal Xtal) as the source of its master clock. It is disabled (greyed-out) when the master clock is set to S/PDIF In. This section indicates the present board sample rate, as set by application software. The sample rate selected here will be used to drive the digital mixer and all outputs. The "Rate Locked" checkbox is used to force a sample rate upon the system. It is disabled by default to allow software access to all supported sample rates. When checked, it causes the driver to only operate at the selected sample rate. This means that any application that attempts to open the Delta DiO driver at a sample rate other than the one selected here will fail to do so. "Reset Rate When Idle" is selected when you want the sample rate to return to a particular setting when a software application is not actively using the board. [. . . ] Often this will result in a small segment of sound (0. 5 to 1 second) repeating itself over and over, sometimes completely locking up the computer. See the general troubleshooting suggestions at the beginning of this section. Problem: A third-party Windows digital audio program does not play or record to/from Delta DiO 2496. Possible Cause 1: The Delta DiO 2496 Audio driver is not properly installed. Install/reinstall all Delta DiO 2496 audio drivers (see Windows Software section). [. . . ]
