tional amplifier. Two subwoofers can be used for stereo bass (which is desirable for music reproduction) or for additional
mono bass reinforcement (for movie soundtracks).
Note: Do not use both the unbalanced (RCA) and balanced (XLR) inputs at the same time. The unbalanced (RCA) and
balanced (XLR) outputs are buffered separately and may be used simultaneously.
X1 Placement
The X1 Crossover may be used on a shelf, or in a standard 19" equipment rack using the optional rack ears and hardware.
See section
Rack Mounting the A1 and or X1
on page 16.
Ideally, the X1 should be placed in close proximity to the receiver or surround processor. Minimizing cable lengths reduces
the chance of noise contamination. If your other audio equipment has balanced inputs or outputs we strongly recommend
connecting the X1 and A1 to your system with them.
If you are using the X1 in combination with the Evolution A1 amplifier, we recommend that you place the X1 underneath
the A1 amplifier. Or, in a stereo configuration, place the X1 between two A1 amplifiers. The A1's are equipped with lamps
under the front edge, which illuminate the X1 controls. See
A1 Courtesy Lights
on page 17 section for more details.
X1 Features and Controls
This section describes the various controls and functions of the X1. Make sure that your X1 controls initially are set as
described in the previous section before continuing.
Power/Standby Mode (Rear Panel)
Your X1 crossover does not have a power switch but has been designed with the ability to turn itself
on and off under various conditions. There are three methods for triggering the X1.
On the rear panel of the X1 is a 3-position switch that determines the trigger mode:
1)
On; the X1 is always on.
2)
Audio; the X1 automatically turns on when it detects an audio signal and turn off after 20 minutes with no signal.
3)
12V Ext; the X1 is remotely turned on when it detects a DC control signal from another component in your system.
The external trigger will accept 5 - 24 volt (DC) signals. For more information regarding external triggers, consult your
authorized dealer.
Master Gain (Front Panel)
The Master Gain control allows you to adjust the volume of the subwoofer relative to the other
speakers in the system. Use the Master Gain judiciously. A properly calibrated subwoofer blends
seamlessly with the Monitors or satellites without calling attention to itself. Here are some general
guidelines for setting the Master Gain control:
