Tools Menu
SRC Mode
Shows the current mode of SRC on the port and is used to enable and disable SRC.
The mode is selected from a drop down list.
The modes available depends on the card type:
820A154
820-154
820-091
To set SRC Mode double click in the Mode column for the required AES port. A small drop down list will appear
with an X next to it.
Double click on the required Mode.
The new Mode will be displayed in the column.
If the resources on a particular card have been used up then the system will prevent attempts to enable SRC on
more ports.
SRC State
Shows the current state of SRC on ports with SRC Mode selected.
Used to select the output rate from a drop down list.
The options available depend on the card type:
820-154 Cards
Input ports will have SRC On or Off according to the SRC Mode selected (i.e. the State is set automatically by
Mode).
Input ports with SRC On will convert the incoming signal to match the console sample rate.
Output may be at sample rates of 44.1k, 48k, 44.056k, 47.952k, 32k or Lock In -> Out.
When Lock In -> Out is selected, the output rate is matched to the input rate on the matching input port (e.g.
output port 1 AES 2 AB would lock to 1 aes 2 AB).
820-091 Cards
Options for both Input and Output ports are:
Synchronous - the port is locked to the system sample rate.
Always 44100 - port locked to 44.1kHz regardless of system sample rate.
Always 48000 - port locked to 48kHz regardless of system sample rate.
Additional Input port options are:
Asynchronous - the incoming signal is buffered and truncated or interpolated with crossfade to compensate for
sample rate discrepancies.
NTSC Pullup - port locked to 44.056kHz if the system sample rate is 44.1kHz, or locked to 47.957kHz if the
system sample rate is 48kHz.
