The Monitor Mixer Page is essentially a collection of volume level faders, audio level or ‘peak’ meters, and solo/mute controls. For each mixer output and input channel there is one of each: a volume fader, a peak meter, a solo control, and a mute control
overload and audio clipping may occur. Therefore be careful to adjust the incoming audio levels so that they do not peak in the red section too long you might use the monitoring capability of the Delta 66 to let your ears be the judge. On all output level meters, 0dB indicates full-scaleoutput. Unlike the inputs, hardware clipping is impossible on the outputs because of the 36-bitresolution built into the mixer hardware. However, please note that it is possible to mix multiple tracks within your software application and cause clipping to occur in the output stream before it reaches the Delta output hardware or monitor mixer
Patchbay/Router Page
3.The third option, “S/PDIF In,” connects ports OUT1 and OUT2 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 OUT1 and the right channel of the S/PDIF In is routed to OUT2
Hardware Settings Page
NOTE Because the digital monitor mixer runs at the sample rate of the rest of the board, and because sample rate directly affects frequency response, it may sometimes be desirable to keep the sample rate at or above 44.1 kHz while using the monitor mixer. This is accomplished by enabling “Reset Rate When Idle” and selecting a sample rate of 44.1 kHz or greater
begin playback and/or recording at the same time. Otherwise select “Independent” to allow the audio channels to play independently — this setting may be desirable if more than one application needs to access the Delta 66 simultaneously

message are two ‘grayed-out’buttons: “CoaxRCA” and “Optical.” These are functions of the Delta DiO 2496, another product in the M Audio Delta line, one with both optical and coaxial S/PDIF inputs. These controls do not apply to the Delta

Delta 66 Recording Tutorials
Typical Setup #1
1.Plug the guitar into the channel-1Line input of the pre-amp.Plug the microphone into the channel-2Mic input
software into which you will be recording. We’ll start with the Delta Control Panel’s “Hardware Settings” page, then the “Patchbay/Router” page, and finally the “Monitor Mixer” page. We’re not using S/PDIF in this example so we’ll ignore the S/PDIF page

9.In the Mixer Input column labeled “WavOut 1/2,” click on each fader handle and drag it up to the 0dB setting. Also, deactivate uncheck each WavOut 1/2 mute box to unmute the channels. This will allow us, once we’ve recorded into a music software program, to hear those software outputs upon playback

Typical Setup #2
NOTE: Because improper connections can potentially make very loud noises, it’s a good idea to have monitor levels down while hooking up audio equipment — you may choose to turn your computer off before making the connections
1.Plug the microphones into the mic inputs 1 & 2 of the pre-amps.Plug the guitars into the high impedance inputs 3 & 4 of the pre-amps

Troubleshooting
NOTE: When resolving conflicts between PnP and non-PnPdevices, it is recommended to re-adjustthe resource settings of the non-PnPdevice first. Typically, Windows is only aware of the resource settings of the installed PnP devices and has no information available to it for adjusting the PnP devices’ resources around those of the non-PnPdevices. The exceptions to this are when: 1 a non-PnPdevice has a true Windows 95/98 driver written for it, 2 the BIOS setup allows reserving an IRQ for a legacy device as opposed to a PnP device, or 3 resource requirements for the non-PnPdevice have been manually entered into the Windows Device Manager. In these cases Windows is aware of the non-PnPdevice’s resource requirements
Sometimes it is possible that a resource problem is not showing up in the conflicting resource list or as a yellow exclamation point in the Device Manager. If you have any doubt about the configuration of your device or just want to double-check,you can view all of the devices and their assigned resources by highlighting “Computer” at the top of the Device Manager list and clicking the Properties button. This will allow you to view a list of assigned IRQ numbers on the left, and the associated devices on the right. If a number does not show up in this list, it means that it is available for use. Look also for IRQs that are shared by more than one device. While the Delta 66 may share an IRQ with some devices, not all devices are capable of sharing IRQs. An entry that reads “IRQ Holder for PCI Steering” along with an installed PCI device such as the Delta 66 is normal. If you see another device showing up on the same IRQ as the Delta 66 such as a video card, SCSI adapter, or USB Host Controller, then it is possible that this is the source of the conflict. Typically, if you move one of the conflicting cards to another PCI slot, an IRQ conflict will disappear

Appendix B -IfYou Use An External Mixer
Some line mixers have a number of effect or auxiliary sends for each channel. These sends will have their own individual level control and will receive the signal either pre fader or post fader, i.e. either independent or dependent on that channel’s fader level. It is possible to use these “aux sends” to send a signal to the recording device. A pre fader send is certainly preferable, since this will allow for a recording level that is separate from the monitoring level
