MAGNEPLANAR® MG3.6/R Instruction Manual MAGNEPLANAR® PRODUCTS WHITE BEAR LAKE, MINNESOTA 55110 www.magnepan.
1. INTRODUCTION Congratulations on your purchase. The Magneplanar MG3.6/R loudspeaker was conceived and designed for perfectionists. One of the most revealing loudspeakers made, it will provide outstanding music reproduction when used with high quality components. Due to the elegant simplicity and ruggedness of the design, the Magneplanar MG3.6/R loudspeaker will give many years of trouble-free service. 2. GENERAL DESCRIPTION The MG3.
5. PACKAGING Save all packaging, including the protective cover for the ribbon tweeters. If you need to transport the speakers, they can be shipped safely only in the original packaging. You may never have to return your speakers, but should the occasion arise, they should not be shipped in any packaging but the original. Should you discard it, factory packaging is available, including special packaging for ribbon tweeters. 6.
7. HOOKUP This section covers amplification with a single stereo amplifier. For instruction on biamplification or bi-wiring, refer to Sections 11 and 12. DIRECT-CONNECT CROSSOVER INSTALLATION A. Insert the small connectors in the four output ports of the crossover box, using a 5/64" hex wrench. See Figure 2, Page 4. B. Screw the support bracket to the bottom of the crossover box with the 3/8" long screw provided. DO NOT OVER TIGHTEN! C.
FUSING – The mid and treble sections of the MG3.6/R are protected with Type SAG normal blow fuses (4 amp for midrange; 2-1/2 amp for tweeter). The bass section does not require fusing protection. The fuse values should never be increased or bypassed. Do not use slow-blow fuses. Fuses remain in effect when bi-amplifying. This is done for your protection since it prevents overdriving from an amplifier, or the distortion that results from an overdriven amplifier (clipping). In case the MG3.
Figure 5 STEREO WIDTH AND IMAGING Once you have located the best position for the speakers and your chair for good bass performance, separate the tweeters by 50% of the distance from your chair to the speakers. (For example, if your chair is 10 feet from the speakers, move the tweeters 5 feet apart.) Now move the speaker apart in increments of 3 or 4 inches at a time, listening carefully at each position.
. ROOM ACOUSTICS Magneplanars, like other bipolar speakers, usually sound best with a moderately reflective surface behind the speakers. In situations where the speakers must be placed closer than 2 feet from the back wall, a heavy damping material directly behind the speakers is advised; however, it should not cover the entire wall. Damping material in other parts of the room is a matter of trial and error.
11. BI-AMPLIFICATION WITH CONVENTIONAL ELECTRONIC CROSSOVER The MG3.6/R is arranged conveniently for bi-amplification. By adding an additional stereo amplifier and a crossover, you can enjoy the benefits of increased dynamic range and lower distortion. 1. Set your electronic crossover at the following points and slopes: Low Pass: 18dB per octave at 250Hz High Pass: 6dB per octave at 200Hz 2. Connect the bass and mid/treble amplifiers directly to the speakers as shown in Figure 6. Do not use the MG3.
12. BI-WIRING OPTION Bi-wiring requires two sets of speaker cables. They may be identical or one set may be specialized for high frequencies and the other specialized for low frequencies. 13. A. Remove both jumpers on the crossover box. B. Connect one set of cables to the low cable input and the other set to the high cable input. Connect the other end of the cables together (observe +/- polarity), and connect to one channel of the amplifier outputs.
15. THE RIBBON TWEETER Because the foil element in your MG3.6/R line source tweeter is only .00015 inches thick, it is very fragile. It's the price we pay for ultra-high performance. Most users will never require a replacement tweeter. Failure will generally occur from mishandling, or from very high impulse signals from a few unusual compact discs used with very high powered amplifiers. Users that frequently push the 2.5 amp tweeter fuse capacity will be the most likely to experience early failure.
16. 60" VERSION 2 RIBBON TWEETER REPLACEMENT Tools Needed: #2 Phillips Screwdriver Needle Nose Pliers 1. Place protective cover over backside of ribbon tweeter, as shown (to prevent damage to ribbon while moving the speaker panel). 2. Carefully lay speaker on a flat table or working surface. 3. Remove the protective cover and pry away the two end covers. 4. Pull off the connector at each end of the ribbon tweeter with a pair of needle nose pliers. 5. Reinstall protective cover over ribbon. 6.
