Emotiva X-Ref 12 Manual Do Utilizador

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:

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.

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).
