Input/Output Protection
Under some conditions, such as a shorted speaker wire, DC voltage on an input
connection or thermal overload, the Citation 5.1 will place itself in a “protect”
mode to prevent damage to your speakers. When this happens the power indicator
will turn red and no signal will be heard. You may hear a relay “click” on as the
unit goes into its protection mode.
When this occurs, turn the unit off using the rear panel switch, and correct the
problem. Turn the unit back on. If the unit continues to go into a protect mode,
contact your dealer or installer for assistance.
Troubleshooting Guide
The Citation 5.1 is designed for trouble free operation. In normal use, most users
will not encounter any problems with the unit. However, as with any sophisticated
electronic device, there may be occasional problems on initial installation, or
during the life of the unit. The items on this list are a brief guide to the minor
problems that you may be able to correct yourself. If these solutions do not rectify
a problem, or if the problem persists, contact your dealer, installer or an authorized
Citation service center for assistance.
