Mirage lfx-3 active subwoofer crossover. Can be used as a 2 or 3 channel crossover. Rated 7 due to age. Great condition. Bought for my main system but changed my plan. Inboxed and hooked up, but barely used. Pickup preferred, shipping at cost.
Mirage LFX-3 Electronic Crossover: Three channel active crossover; crossover frequencies - 50, 60, 80, 100 Hz; low pass 24 dB/octave; high pass 12 dB/octave. Original list: $700. Can also be used for 2-channel stereo (left and right) or mono for use with a center channel. The crossover is fed by the L,C,R (Left, Center, Right) line level output signals from an A/V processor or stereo preamp. High pass filtered signals from the crossover are fed to the L,C,R power amplifiers. The crossover is capable of driving 1 subwoofer-summed L,C,R low pass; 2 subwoofers-L+1/2C and R+1/2C low pass; or 3 subwoofers-L,C,R low pass. The center channel has selectors for the crossover frequency, the low pass shape, high pass shape (fine tunes the slope), image (blends real and phantom information with the rest of the system speakers and subwoofers), and level (for adjusting center channel level compared to right/left). A second set of selectors controls the left/right subwoofer channels, and has the crossover frequency as well as low pass - high pass shape controls (independent of the center channel controls). A master level control allows setting the subwoofer output for all three channels at once. Besides the on/off/bypass toggle, there is a toggle for 1,2, or 3 subwoofers (sums all three when set to 1), and a 180 degree phase toggle. The LFX-3 has three line level RCA jack inputs (Left, Center, Right), three line level RCA jack outputs for high pass to the amplifiers for speakers which will be handling the mid-range and highs, and three line level RCA jack low pass outputs which can feed up to three separate powered subwoofers. The LFX-3 is powered by a 16 vAC transformer which plugs into the AC outlet, with a cable that plugs into the back of the LFX-3.
The LFX-3 is an external crossover with a twist. Not only will it allow you to blend three front channels (instead of the usual two) with one, two or even three subwoofers, but it will also allow you to mix the center-channel signal into the left and right channels. Patented phantom/real image system allows the option of having a real center-channel signal, phantom center-channel signal or anything in between. Simple, but effective, it generates a hybrid center channel acoustic image. In the phantom position the center channel is turned off. Conversely in the real position there is only the hard real center signal. You can generate an image that is a combination of x percent real center and y percent of phantom center. And by doing that you can eliminate the “in your face image” that the real center channel often gives you and the accompanying loss of the spatial characteristics of your left and right speakers when the center image comes from the actual center channel speaker. It allows you to simultaneously retain the desired spatial aspects conveyed by the left and right speakers and lock the image to the screen center with x percent of the real center signal.
The high-pass filter can be set at 50, 63, 80 or 100Hz for the mains and/or the center channel. The slope of both can also be altered to further allow for better integration with the subwoofers. Phase can be inverted by 180 degrees. A bypass mode is also provided to allow for full-range signals to pass through the LFX-3 to the speakers.
Obm, power adapter.
