What is needed to engage a pre-eq send on the Venice console?

To engage a pre-eq send on the Venice console, the correct aux send setting is essential. This setting determines how the signal is processed and sent to the auxiliary outputs. When the aux send is configured properly, it allows the console to send an unaltered version of the audio signal before it passes through any equalization or effects. This is crucial for applications where a clean and unaffected signal is required for monitoring or for sending to external processing equipment.

The other options, while they may be relevant in different contexts or setups, do not specifically address the configuration needed to engage a pre-eq send. For instance, patch cables are necessary for connecting various components in the live sound setup, while an external mixer may not be required at all if the Venice console is functioning independently. Software adjustments could pertain to other aspects of the console's operation, but they are not specific to the pre-eq send configuration. Thus, the correct aux send setting is the key element needed for this operation.
