Sirius 800 Series User Manual 4929 Sirius 800 Audio AES/MADI Output with Audio Delay Output Modules and Rear Panels 11.1

SRC straight through mode

• If an AES pair doesn't have sample rate conversion enabled (Use SRC unchecked)

and doesn’t have a reference selected (Reference Disabled) then that pair will be

output at the same sample rate as the left channel of the pair. In the case of a MADI

stream all of the pairs will be output at the same sample rate as the first active

channel of the MADI stream.

Example SRC straight through mode (AES)

SRC settings required for SRC straight through mode for one or more of a group of eight AES

pairs (See Figure 115 on page 178 for setting locations):

SRC Rate: Any

SRC Reference: Disabled

SRC Enable: Checked

Use SRC: Unchecked for the pair(s) required to work in SRC straight through mode

Example SRC straight through mode (MADI)

SRC settings required for straight through mode for a MADI stream

(See Figure 116 on page 178 for setting locations):

SRC Rate: Any

SRC Reference: Disabled

SRC Enable: Checked

Use SRC: Unchecked

Note:

• The maximum sample rate that can be input to the SRC in straight through mode is

50 kHz.

• AES - If channels within a pair are asynchronous to each other then sample drop or

repeat is used on the right channel to match the left channel.

• MADI - If channels from the audio crosspoint are asynchronous to each other then

sample drop or repeat is used on all channels to match the first active channel in

the MADI stream.
