The "Settings" window.
Here's where we come to the real nuts and bolts. To be more precise, to a number of sophisti-
cated technical details—which aren't very difficult to understand, however. Specifically, these
are:
The Settings page for the configuration of drivers, digital interfaces/filters and the color settings of the
ControlPanel.
The Master Clock.
Here we're dealing with the sample rate used by your SoundSystem Aureon 7.1 Universe. This
is—depending on the application—a very important point, as the card can be (and in some
cases, must be) controlled by an external signal (from a MiniDisc recorder, for example), or it
can specify a rate for itself internally and can share this signal via the digital interfaces with
other devices being used for recording.
If a valid S/PDIF signal is being applied to a digital input, its sample rate will be displayed in
the Aureon ControlPanel, and the SoundSystem can and should be set to this external sample
rate (External). If you forget this step, audible errors such as dropouts and clicks may occur
during recording—and already when monitoring the signal.
Naturally, you should also pay attention to the settings of your periphery in the reverse situa-
tion (synchronizing an external device with the Aureon 7.1 Universe). In that case, set the
Aureon ControlPanel to "Internal", as it also would be when you are not using external digital
devices. If the devices are to be permanently connected to one another in both directions, you
must decide which device will provide the clock signal.
The digital interfaces of the Aureon 7.1 Universe support all bit resolutions between 8 and 24
bits, as well as all sample rates between 8 and 96 kHz. Please note that not all devices can
process sample rates higher than 48 kHz. To transfer a signal recorded at 96 kHz to a minidisk
recorder, it's probably necessary to convert the file(s) to 44.1 kHz or 48 kHz first.
The "Sample rate locked" function locks the sampling rate at a defined value. This function is
used mainly in conjunction with games or programs which use voice over IP, to ensure that
the speech is reproduced correctly and without distortion.
