3.Select either the Crossover Mode Active or Bypass (#1). The Crossover Mode Active switch position should be used when connecting your MIRAGE® subwoofer to a receiver without bass management or when you wish to manually control the crossover and volume settings (such as in a music system).
The Crossover Bypass switch position should be used when connecting to a receiver with bass management (such as in a digital surround sound movie system). This connection defeats the crossover feature on the MIRAGE® subwoofer, allowing this control to be handled by the receiver. Adjusting the front panel Volume Control (#3) will still be required.
4.Ensure that the high-level speaker inputs have been securely tightened, as this ensures that the inputs will not vibrate audibly.
5.See Final System Adjustments, below.
METHOD 2 – STEREO APPLICATIONS
1.On the rear of the receiver/pre-amp there should be stereo (left and Right) RCA type jacks marked “Left and Right Pre-Amp Outputs”. Connect a pair of RCA cables from those jacks to the LFE/Left Input and Right Input (#7) on the bottom of the subwoofer. A standard male to male RCA cable is needed.
2.After connecting the stereo low level Inputs (#7) connection, plug your MIRAGE® subwoofer into an AC outlet. Do not use the AC outlet on the rear of your receiver. After plugging in the unit, switch the Main Power to On.
3.Select the Crossover Mode Active. The Crossover Mode Active switch position should be used when connecting your MIRAGE® subwoofer to a receiver without bass management or when you wish to manually control the crossover and volume settings (such as in a music system). Adjusting the front panel Volume Control (#3) will still be required.
4.When connecting bookshelf/satellite speakers that have limited bass output you can use the Low Level Outputs on your subwoofer to eliminate low frequencies from being sent to your small speakers. Connect the Left and Right Outputs to the left and right inputs on your stereo amplifier. The Stereo Outputs (#8) are filtered at 80Hz, 6db/octave. This should provide you with greater system dynamic range.
5.Ensure that the high-level speaker inputs have been securely tightened, as this ensures that the inputs will not vibrate audibly.
6.See Final System Adjustments, below.
METHOD 3 – SPEAKER LEVEL – FOR MUSIC APPLICATIONS
1.The other way to connect your subwoofer to your receiver is using a High-Level (#9) (speaker wire) connection, by simply connecting the speaker wires from the Front Left and Right Speaker Outputs on your receiver to the Left and Right Inputs on the bottom of the subwoofer (#8). It is imperative that speaker polarities be maintained, one must connect the positive and negative wires to the appropriate positive and negative terminals. Failure to do so will result in an out of phase connection, severely limiting the amount of bass in your system.
2.After connecting the High-Level (#9) (speaker wire) between your receiver and subwoofer, ensure no fray wires are touching, as this could cause a short circuit and damage your electronics. Plug your MIRAGE® subwoofer into an AC outlet. Do not use the AC outlet on the rear of your receiver.
3.See Final System Adjustments, below.
Do NOT connect both RCA and High-Level connections simultaneously, as this will damage your MIRAGE® subwoofer.

FINAL SYSTEM ADJUSTMENTS
1.After having turned on the main power switch and having broken-in the speaker, select the correct position for the Power Mode switch (#5), either On or Auto depending on your system. The Auto selection will leave the unit in a self-sensing mode, such that should the unit sense an audio signal it will turn itself on and then shut down after several minutes without signal, while in the On position the subwoofer always remains on. Should the system not be used for an extensive period of time, it is recommended that the subwoofer be unplugged from the AC outlet or the Main Power Switch (#9) be turned to the OFF position.
2.Adjust the Volume Control (#3) on the front panel of your MIRAGE® subwoofer so that the volume of your subwoofer matches the overall system volume. This ensures a smooth transition between the low and high frequencies of your system.
3.Adjust the LP Filter Setting (#2) on your MIRAGE® Speakers subwoofer so that the frequency range of the subwoofer blends well with that of the front speakers (For use with all settings, except when in Crossover Mode Bypass). Setting the crossover too low will create a gap between the frequency response of the front speakers and that of the subwoofer, while setting the crossover frequency too high will create a doubling of certain frequencies, making the music sound boomy. When using small satellite speakers, the appropriate crossover frequency should be from 90Hz to 150Hz, for the bookshelf speakers 70Hz to 90Hz and for the large floorstanding speakers 30Hz to 70Hz.
4.Adjust the Phase control (#4) so that the subwoofer integrates fully with the rest of your audio system. This control is infinitely adjustable and ensuring that the subwoofer operates in phase with the rest of the system is critical, as an out of phase subwoofer will either sound like it is lacking in bass performance or that its timing is off. This setting will be determined by your listening position, the characteristics of your listening room and its interaction with your MIRAGE® subwoofer. An out of phase speaker means that the speaker cone is moving inwards when it should be moving outwards, like the other speakers in your system, causing cancellations of certain frequencies. By adjusting the phase control, one can ensure that all speakers move in the proper direction, at the same time.
5.Steps 2, 3 and 4 might require repeating in order to fine tune your system. Ensuring the proper blending between the speakers and the subwoofer is critical to the performance of your system, as a whole.
