Packaging Save all packaging. Should you discard it, packaging is available from Magnepan. 4. Placement and Installation Before a permanent installation is begun, we suggest that the Magneplanar Temporary Mounting Kit be used to determine if the selected location gives the desired audio performance for the MMC 2s. A set of mounting brackets are included with the MMC 2 for this purpose. [. . . ] The manufacturer of a full-range speaker gives considerable attention to achieving correct phasing between the midrange and bass drivers. To get the full benefit of your high performance MMC 2s, we suggest that you get the help of your dealer or a technician to ensure that the phasing between the MMC 2s and your woofer is correct. A Magnepan "Shaped" Pink Noise CD Test Disk is included with your MMC 2s to assist in the proper phasing between the MMC 2s and your woofer. The pink noise CD is "shaped" with a 9 db peak at 80-100 Hz. This peak in the midbass focuses the attention of the listener on this area of the frequency response. When the MMC 2s are out of phase with the woofer, this peak will be reduced in level. Place the Magneplanar Woofer (or subwoofer) next to the MMC 2s (It is much easier to detect an out-ofphase condition when the "small" speaker is physically next to the Woofer. ) A technique which can aid in determining if the phase is correct is by leaning over and positioning your head equidistance between the Magneplanar Woofer and the "small" Magneplanar as shown in Fig. High frequencies will appear to be up and low frequencies will appear to be down. The 90-100 Hz peak, if in phase, will appear to be in the middle (and louder). Since the Magneplanar Woofer is a dipole, the rear wave is out of phase with the front wave. To reverse the phase for a phase test, simple turn the Maggie woofer around. However, depending on where the woofer is placed, it is possible for the MMC 2s and the woofer to be 90 degrees out of phase with the woofer. This will result in little or no difference in loudness of the peak as the phase is changed. Usually, this means that the woofer is not placed at the correct distance relative to the MMC 2s. Many powered woofers have continuous phase shift adjustments to correct this problem without moving the woofer, although changing the location of the woofer is the preferred solution. 6. Speaker Angle Adjustment For the best sound, the MMC 2 should be angled so that the panel is on-axis with the listener with a minimum distance from the wall of 30 degrees. (Use of the MMC 2 as a dual center channel speaker requires slightly different adjustments. Insert the long 5/64 inch allen wrench into the Cam/Stop at the bottom of the speaker as shown in Fig. The angle of the MMC 2 should never be set for less than 30 degrees for optimum sound. Fig. [. . . ] Depressing the switch to the left will reduce the high frequencies with a 1 ohm resistor. 9. Service and Shipping In the unlikely event you should need service for your MMC 2s, we recommend you return it through your dealer. He is experienced in providing service and can assist you if the speaker must be returned to the factory. If you determine you need to return it directly to Magnepan, call for a return authorization and ship the speaker freight prepaid to: Magnepan, Incorporated 1645 Ninth St. [. . . ]
