Operation
Once you have decided upon a location for your X-Ref 12 DSP Powered Subwoofer, and
connected and configured it and all associated equipment, operation is very simple.
• Plug your X-Ref 12 into a grounded electrical outlet of appropriate voltage.
(The X-Ref 12 will automatically switch between 110-120 VAC and 220-240 VAC.)
• Connect a signal source to either the unbalanced (RCA) or balanced (XLR) input on
the rear panel of the X-Ref 12.
• Place the Power switch on the rear panel of the X-Ref 12 in the On position.
• Immerse yourself in the music!
In general, once your X-Ref 12 is properly connected and configured, no explicit control
by the user is required.
Rotary encoder and back lit LCD display
The push-to-engage rotary encoder (located on the top panel of the X-Ref 10) is used
to enter or change configuration information; the encoder is active when the display
is lit. The encoder is made of a soft rubber material, and rotates when gentle pressure
is applied. In general, the encoder is rotated to change a displayed value, and pressed
like a button to accept a value or enter a command. You will probably find it easiest to
rotate the encoder using your thumb and one finger positioned on the top surface near
two opposite sides; you can press the center or the entire top surface. The display and
encoder will disengage and “sleep” if idle for a short time, but will remain active if you
pause while in the middle of a configuration sequence. A single press of the encoder
will activate the display and engage the encoder when it is off.
Status display
The X-Ref 12 includes a small status LED towards the top of the rear panel. When the
X-Ref 12 is powered on, but no signal is present, this LED will glow red to indicate that
the X-Ref 12 is in low-power Standby mode. When signal is present and the subwoofer
is operating, or when the LCD display is in use, this LED will glow green.
Automatic switching
When the Power switch is in the On position, the X-Ref 12 will wait in Standby mode
until a signal is present at either input, at which point it will turn on. After several
minutes with no signal, the X-Ref 12 will return to Standby mode.
Movie EQ Trigger
If the X-Ref 12’s Movie EQ trigger is connected to a pre/processor, a boost in low bass
of about +6 dB at 45 Hz will be activated whenever +12 V is present on the trigger
input.
