Core2 Page:

The Core2 page is used for configuring audio routing.
The example below shows the Analog Inputs, Outputs 1-4 & Outputs 5-8 and S/PDIF In & S/PDIF Out are
enabled.

The “Core2” page (above) is also used for changing the settings of the Analog Input Level faders.
There are four LED’s labeled

dbx 1-4

(located at the lower right of the LexPanel) that are used to monitor

the status of the jumpers W1-W8 on the Core2 Main board. All of the following tests are specified with the
dbx circuits enabled and the jumpers installed at W5-8.

OFF (Dark Green) = dbx Disabled
ON (Bright Green) = dbx Enabled
