M-Audio Delta RBUS Инструкция по эксплуатации онлайн [48/60] 19013

5. Open the Delta Control Panel by double clicking the icon in your

Windows Control Panel (or, on the Mac, wherever you’ve placed your

control panel), and then click on the ‘Hardware Settings’ tab.

6. Select ‘Internal Xtal’ as the master clock source. This allows the Delta

R-BUS to derive its sample rates from its internal clock oscillator.

‘Internal Xtal’ is the default setting for the Delta Control Panel, so

selecting it may not be necessary (it may already be selected).

7. Under "CODEC Sample Rate," verify that the "Rate Locked" checkbox

is not activated. This will allow your application software to set the

Delta R-BUS sample rate as it pleases.

8. Since this example will include the use of the monitor mixer, we will

activate the "Reset Rate When Idle" feature. This will make sure the

monitor mixer is running at a decent sample rate while the system is

idle – this prevents the mixer sample rate from being set too low and

therefore lowering its frequency response. Select a sample rate in the

"CODEC Sample Rate" group to use as this idle sample rate. Choose

a 44.1kHz or higher setting for best results, and select the same sample

rate you will be using in your application if possible. We’ve chosen

44,100kHz for this example, which is a standard operating sample rate

for digital multitracks should you decide to transfer this audio to a

Roland device. A general rule of thumb is to multiply the highest

frequency you would like to capture by two and add maybe a little on

top of that – that gives you a suitable sample rate. Also keep in mind

that if the final results of your work will end up on a CD-ROM burned

from your WAV file or AIFF, you probably want to use 44.1kHz, the

native sample rate of "redbook" CD audio.
