Emotiva X-Ref 12 Manual Do Utilizador

Page 10

Typically the balanced (XLR) input is used to connect the X-Ref 12 to the balanced 

output labelled “subwoofer” or “LFE” (low-frequency effects) on a home-theater pre/

processor, and the stereo unbalanced (RCA) inputs are used to connect the X-Ref 12 to 

the output of a stereo preamp. The X-Ref 12 automatically switches on when it senses 

signal on either input. 
In addition, the X-Ref 12 offers a feature which automatically adds a little extra punch 

when you’re watching a movie (it increases low bass by about +6 dB at 45 Hz). This 

feature is enabled by connecting the Movie EQ Trigger input on the X-Ref 12 to the 

trigger output on your home-theater pre/processor. (Assuming you have a stereo music 

source connected to the unbalanced inputs on the X-Ref, and a home-theater pre/

processor connected to the balanced input, the Movie EQ Trigger input can activate the 

bass boost when the home-theater pre/processor is turned on). 
If you have a pre/processor (like Emotiva’s UMC-1) which has programmable trigger 

outputs, this allows the Movie EQ boost to be turned on by the pre/processor for 

certain types of program material.  
The Movie EQ can also be manually configured via the DSP Management System menu. 

Refer to the diagram on Page 19 for details.  

The balanced (XLR) output on the X-Ref 12 provides a duplicate of the input signal and 

is intended for connecting one or more additional X-Ref 12 (or other) subwoofers.
