Manual abstract: user guide MIRAGE SPEAKERS 90IS
Detailed instructions for use are in the User's Guide.
[. . . ] Extensive research along with great care at every design stage has enabled Mirage to produce loudspeakers with extraordinary performance characteristics: a performance level that is equal, or superior to other speakers costing many times their price. The finest components and materials, made with sophisticated manufacturing and quality control ensure that you will enjoy this exceptional performance for many years. IMPORTANT: Please retain the carton and packing material for this Mirage product to protect it in the event it ever has to be shipped to a service center for repair. [. . . ] It is therefore important that consideration be paid to the left and right reflecting walls. First, they should be symmetrical, equally spaced from the speakers and the listeners. Secondly, they should have the same, or very similar reflective properties. Example: A curtain on one wall and a painted surface on the opposite wall will result in unbalanced reflections, which in turn affect the stereo image. Experiment with toe-in/toe-out positioning of your speakers until best results are achieved. The loudspeakers should be placed 2 to 3 meters (6" to 10") apart and approximately 1/2 meter from the wall behind the speaker. The distance from loudspeakers to listener should be about 1 to 1. 5 times the distance separating the speakers (see figure 1).
Selection of Proper Wire
We recommend the use of high quality speaker cable. The speaker cable you select will ideally be fitted with high quality connectors with either 5/16" spade lugs or dual banana plugs. In most installations, ordinary lamp cord (16-18 gauge) has enough resistance to degrade the signal between amplifier and speakers, particularly in lengths over 3 meters (10'). If possible the speaker cables should be the same length for both channels and the shorter they are, the better the sonic performance will be. * When connecting your speakers to your sound system, turn off your amplifier to avoid damage which could result from shorting of the speaker leads.
Amplifier Requirements
Mirage loudspeakers have been designed to be driven to high listening levels with moderate power, while at the same time being capable of handling the power output of large amplifiers. NOTE: Mirage 90is Series speakers are 8 ohms nominal and will function well with quality amplifiers.

manual
1) Conventional Hook-up Connect speaker wire from the positive (Red +) terminal on your amplifier to positive (Red +) terminal on your Mirage speaker. Connect negative (Black ) terminal on your amplifier to negative (Black ) terminal on your Mirage speaker. Use two dual conductor cables; one cable for low frequencies and one cable for high frequencies. Separate connections are made between the power amplifier to the low frequencies binding posts on the speaker and from the power amplifier to the high frequency binding posts. This allows you to choose separate wires that are best suited for the low or high frequencies. (see figure 3) 3) Combination Bi-Amp/Bi-Wire Hook up This method uses separate amplifiers for the low frequency section and high frequency section of the speaker. This dramatically improves musicality. The amplifier's gains and the phase relationship of the amplifier's input to output must be identical. (see figure 4)

Care of Finish
Your Mirage speakers are attractively finished and should be gently wiped clean, from time to time, with a damp cloth to remove any dust or stains.
Distortion Causes Speaker Damage
When an amplifier is "overdriven" it produces distorted output power several times greater than its rated power. All amplifiers produce high levels of distortion when they are driven beyond their rated power output and this distortion can damage any speaker. If this is heard, lower the volume immediately to avoid damage to your system. If louder volumes are desired, the only practical solution is to obtain an amplifier capable of more clean (undistorted) output power.
