Chapter 4 Performance Verification

This section describes a quick verification of the operation of the Lexicon Core2 system and the integrity of its analog and digital audio signal paths. These tests should be performed without any programs running on the PC. Preferably, the tests should be run after a fresh start-up.

Test Overview:

These tests verify the analog and digital audio paths through the Core2 Connector Box and the Core2 Main board installed in the computer. The audio testing is preformed using the LexPanel.EXE program. The LexPanel provides multiple paths of audio routing so that in the event of a failure, the defective circuit can be located and repaired.

User Interface:

The LexPanel consists of three pages that are used for selecting the Audio Inputs, Audio Outputs, Sample Rate, Clock Source, etc. Double clicking on the LexPanel Icon in the lower right hand section of the task bar can access these pages. Each tab of the LexPanel can be accessed by using the mouse or via the function keys F5, F6 & F7.

F5 is for the Punch page F6 is for the Clock Source page F7 is for the Core2 page

Punch page:

The Punch page is used for selecting the Audio Inputs and Audio Outputs to be tested. The example below shows the Analog Input 1 (A/D 1) being routed to the Left S/PDIF Digital Output (S/PDIF Out L).
