M-Audio Delta TDIF Инструкция по эксплуатации онлайн [25/58] 19006

CODEC SAMPLE RATE: 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 TDIF

driver at a sample rate other than the one selected here will fail to do so

and will post an error message. "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. This is particularly handy for

keeping the digital mixer running at a specific sample rate.

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 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.

S/PDIF SAMPLE RATE: When using S/PDIF In as your master clock,

this section tells the driver what the expected S/PDIF input sample rate

is. The section is only displayed when the board is set to use S/PDIF In

as the master clock source. From the list, select the sample rate closest to

that of the S/PDIF input data. The sample rate selected here will be the

only sample rate available to the software applications. Therefore, you

must set your audio software application to this same sample rate or else

the application will display an error message.

NOTE: When S/PDIF In is the master clock source, the digital

monitor mixer will run at the sample rate received at the S/PDIF In.

Since frequency response and sample rate are directly related, the

mixer frequency response will be directly related to the sample rate

of the S/PDIF input data.

TDIF Clk SAMPLE RATE: When using TDIF Clk as your master clock,

this section tells the driver what the expected TDIF Clk sample rate is.

The section is only displayed when the board is set to use TDIF In as the

master clock source. From the list, select the sample rate closest to that of

the incoming word clock. The sample rate selected here will be the only

sample rate available to the software applications. Therefore, you must

set your audio software application to this same sample rate or else the

application will display an error message.

NOTE: When TDIF In is the master clock source, the digital monitor

mixer will run at the sample rate received at the TDIF in. Since

frequency response and sample rate are directly related, the mixer
