Connections

Inputs
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.
Outputs
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.
