Disable SRC |
When clicked, the sample rate converter for this channel is disabled. This allows you to use an external device for sample rate conversion. Once you have configured your sample rate converter, you will need to lock the audio output from the device to the sample clock in the NioNode. Note: MediaMatrix uses high quality sample rate converters, so there is generally no need to use separate devices. |
|
Error |
Lit (red) when an error is detected on the incoming audio data stream. There is a single LED for each digital channel (2 audio channels). |
|
Professional |
Lit (green) when the audio data stream is labeled as professional (AES data, for example), or unlit when the data stream is labeled as consumer (S/PDIF data, for example). The signal levels required to work with the different standards are controlled by DIP switches on the AES card. For more information, refer to AES card DIP switches in the NION Hardware Manual. |
|
Lock |
Lit (green) when the device has locked to the incoming audio data stream. |
|
Copy |
Lit (green) when the copy bit on the AES audio stream is set. This means the data is not copyright protected. |
|
Audio |
Lit (green) when valid audio data has been detected on an input. |
|
Ext clock source |
Lit (green) when a clock signal is being received from an external source into a connector on the AES card. |
|
Sample Rate |
The sample rate of the incoming AES data stream. This is the sample rate of the input signal before conversion. |
|
Emphasis |
Encoded audio signal emphasis, as described in the AES3-2003: AES standard for digital audio engineering - serial transmission format for two-channel linearly represented digital audio data. For more information, refer to the standards section of the Audio Engineering Society website. |
|
???? |
Emphasis not specified. Receiver defaults defaults to no emphasis, but may be manually overridden. |
|
None |
No emphasis. Receiver may not be manually overridden. |
|
50/15 us |
Signal has been emphasized using a 50/15 uS filter. Receiver may not be manually overridden. |
|
CCIT .J17 |
CCITT J.17 pre-emphasis filter with 6.5 dB insertion loss at 800Hz. Receiver may not be manually overridden. |
|
Origin |
Alphanumeric identifier for the origin of the AES data stream. This value can be edited for output channels. Maximum length is 4 characters. |
|
Destination |
Alphanumeric identifier for the destination of the AES data stream. This value can be edited for output channels. Maximum length is 4 characters. |
