Troubleshooting
If you have followed all of the instructions for obtaining audio, but are not hearing
anything through the speakers, there are a number of quick checks you can go through
to make sure you haven't missed out anything or that nothing is amiss. The following
provides a quick checklist:
• Make sure the appropriate ST buttons in the channel fast strips are on.
• Make sure the appropriate ST buttons in the source a/b panels (monitors section of
the output bay) are on.
• Make sure nothing is muted.
• Make sure no faders are set to minimum.
• Check that the VCA/group master faders are at unity gain.
• Use solo at selected points in the signal path to try and pinpoint where the signal is
being lost.
• Check for correct signal routing by making sure channel sources/destinations are
correctly assigned.
To make provision for the highly unlikely event that the active master controller (MC)
develops a malfunction, we recommend that you copy the show file to both MCs before
the performance. This will enable you to carry on with the show using the same show
file after carrying out an MC swap. To do this, copy the show file to a USB memory
stick (see "Saving your show files to USB memory stick" on page 197), switch active MC
(reset the MCs) and copy the show file to the other MC, which is now the active one.
To swap the MCs
active master controller via the GUI" on page 198) and press the appropriate MC
reset switch to shut down this MC. Then press the reset switch of the other MC
to activate it; the alert buttons at the top of the GUI screens will change to
green when the XL8 is ready for operation again.
The MC 1 and 2 switches, mc - 1 and mc - 2, respectively, are contained in a
bank of four (shown right) on the control surface, just to the right of the I zone.
(The other two switches are the router reset switches, which should not be
operated; a router swap is performed via the GUI.)
To check active master controller via the GUI
This is done by noting which of the two MCs is shown as green on the Diagnostics
screen on the GUI; the redundant one is red. In the following example, MC 1 is active.

on the control surface. In future XL8 versions this procedure will be under software control
and will be carried out via the GUI's Diagnostics screen.
