selected sample rate. This means that any application attempting to open the
VX442 driver at a sample rate other than the one selected here will fail to do
so and will send an error message. “
Reset Rate When Idle ” is to be selected to
reset the sample rate to a particular setting when a software application is not
actively using the board. This is particularly helpful for keeping the digital
mixer running at a specific sample rate.
Note: Since the digital monitor mixer runs at the sample rate of the rest of the
board, and as sample rate directly affects frequency response, it may
sometimes be advantageous 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.
AES/EBU SAMPLE RATE
When using AES/EBU In as your master clock, this section tells the driver
what the expected AES/EBU input sample rate is. The section is only
displayed when the board is configured to use AES/EBU In as the master clock
source. From the list, select the sample rate closest to that of the AES/EBU
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 AES/EBU In is the master clock source, the digital monitor mixer will
run at the sample rate received at the AES/EBU input. Since frequency
response and sample rate are directly related, the mixer frequency response
will be directly related to the sample rate of the AES/EBU input data.
MULTITRACK DRIVER DEVICES
The VX442 drivers may intelligently synchronize the beginning of recording
and playback across all audio devices on the board. When using application
software that is capable of using multiple channels simultaneously, select
“
Single and In-Sync ” to ensure that all audio channels will begin playback
and/or recording at the same time. Otherwise select “ Independent ” to allow the
audio channels to play independently - this setting may be looked-for if more
than one application need to access the VX442 simultaneously.
