User manual M-AUDIO DELTA AUDIOPHILE 2496

[. . . ] . 34 Introduction Congratulations on your purchase of the Audiophile 2496. The Audiophile 2496 is a part of the "Delta" series of digital recording systems and interfaces, designed and manufactured by M Audio, and therefore benefits from the same solid hardware and software driver technology as the other members of the Delta series. Even if you are experienced in digital recording, please take the time to read this manual. It will give you valuable information on installing your new card and the supporting software, plus help you to fully understand the function and usability of the Audiophile 2496. [. . . ] The peak meters indicate the incoming "pre-fader" levels of the incoming audio and are therefore not affected by the fader settings. However, the input faders do affect the levels of the signals exiting the mixer and you will see the effect of the input faders on the output "Master Volume" peak meters. From left to right, the inputs to the mixer are labeled "WavOut 1/2", "WavOut S/PDIF", "H/W In S/PDIF" and "H/W In 1/2". The first two inputs accept the digital audio streams being sent from your software application (or Windows) to the driver devices with those same names. Each name begins with "WavOut" to remind you that these are software streams and may not necessarily be routed to any physical outputs (see Patchbay/Router Page). The rightmost two channels are audio streams 18 from the physical Audiophile 2496 hardware inputs, hence the "H/W" at the front of each name. On the Mac, these inputs are labeled "SM/ASIO", as these software streams will be receiving their digital audio either from the Sound Manager or the ASIO driver, depending on your selection. PAN: Each mixer input may be individually panned anywhere in the stereo output mix. A pan control is positioned directly under each input channel peak meter and has the appearance of a small vertical pointer. To make a coarse adjustment, click on the pan control with your mouse and drag it to the desired position. For finer adjustment (in 1% increments), you may click on the pan control to make it active, and then use the left/right or up/down cursor keys on your computer keyboard. Either way, while the pan setting is being adjusted, its value will appear numerically in the Master Volume's status box (below the Master Volume Stereo Gang control) as a percentage from left pan to right pan: -100% represents far left, +100% represents far right, and 0% represents the center. SOLO: Each mixer input channel has a "Solo" checkbox associated with it. Clicking on and activating a Solo box will solo the selected channel by essentially muting all other signals. When more than one channel has Solo selected, all solo channels will be summed to the solo `buss' (path), which is what one might consider an `in place' solo as opposed to a PFL, or pre-fader listen (levels and pans still apply). Deactivating all solo boxes will return all input channels to their previous mute/unmute states. MUTE: Every mixer input channel has a "Mute" checkbox associated with it. Clicking on and activating the Mute box will remove that signal from the stereo buss. Deactivating the Mute box will add the signal back into the stereo buss. STEREO GANG: All input channel pairs have a "Stereo Gang" capability. Clicking on and activating the Stereo Gang checkbox will link (or "gang") the left/right faders so that both channels may be adjusted together as a stereo pair. Patchbay/Router Page The Patchbay/Router page allows you to connect each of the Audiophile's hardware outputs (a pair of analog outputs and a pair of digital output channels) to specific audio sources within the Audiophile 2496 board. [. . . ] Then if a sound starts again at a different sample rate, the Audiophile clock is changed again to meet that new sample rate. To eliminate this, uncheck the "Reset Rate When Idle" checkbox. Problem: I am playing AC-3 or surround sound data from a software application on my computer, sending the data from Audiophile S/PDIF Out to my home theatre's AC-3 decoder. However, the decoder does not recognize the signal and therefore refuses to put out any audio. [. . . ]
