Troubleshooting - Emotiva X-Ref 12 User Manual

Troubleshooting

Emotiva's X-Ref 12 DSP Powered Subwoofers are carefully designed and manufactured
from high-quality precision components to ensure years of trouble free operation.
The troubleshooting section describes some common problems and how to eliminate
them. If this doesn't solve your problem, please contact Emotiva Technical Support,
where a real person will be glad to help you get up and running.
Please remember to power down your X-Ref 12 and all connected equipment before
changing or disconnecting cables.
The following two procedures will address the vast majority of problems that you may
encounter:
Check the power connections:
Verify that your X-Ref 12 is turned on (the Power switch is on the back) and plugged
into an active AC outlet. If the X-Ref 12 is turned on, the Power LED on the back of
the unit should be lit (red indicates Standby; green indicates Active) and the blue
fluorescent display (on top of the X-Ref 12) should light if you briefly press the button
in the center of the rotary encoder (the black circle next to the display).
If not, verify that the Power switch is set to On, that the power cord is firmly inserted
into the back of the X-Ref 12 and an AC outlet, and that the AC outlet is alive. If so,
then verify that the fuse in the X-Ref 12 is not blown.
Check the signal source:
Verify that your signal source is sending output to the X-Ref 12. Some devices don't
send output to one or more subwoofer outputs unless configured to do so. In addition,
some home theater pre/processors only send output to the subwoofer when certain
types of program material are playing and certain decoder options are chosen (for
example, some don't send output to the LFE output when playing stereo material).
If your X-Ref 12 appears to "work" with some content and not other, check the
documentation that came with your source component.
If the rear panel indicator LED is red, this indicates that the X-Ref 12 is in Standby
mode (and that no input is being received).
