[. . . ] MAGNEPLANAR® MG20. 1 Instruction Manual White Bear Lake, Minnesota www. magnepan. com 1. INTRODUCTION Congratulations on your purchase. The Magneplanar® MG20. 1 loudspeaker was conceived and designed for perfectionists. One of the most revealing loudspeakers made, the MG20. 1 will provide outstanding music reproduction when used With high quality components. [. . . ] CABLE HOOKUP The MG20. 1's feature high-current cable connectors which provide optimum contact area with speaker cables up to 10 gauge. To prepare cables, strip 1/2-inch of insulation from the end of the cable. Insert the bare wire into the connector and tighten the set-screw with the Allen wrench provided. Spade lug adapters are available from your Magneplanar dealer for speaker cables that are incompatible with the Magneplanar high-current connector. SINGLE AMPLIFIER OPERATION For single amplifier operation an XO20. 1 Passive Crossover has been supplied with your speakers. Angle brackets have been provided for attaching the XO20. 1 Crossover to the feet of the MG20. 1's. This will ease moving and positioning the MG20. 1's. Loosen top screws on back of feet, just enough to slip angle brackets on. Align the 4 gold connectors on the crossover to speaker inputs and place crossover on angle bracket. Connect the amplifier speaker cables to the input of the XO20. 1 Crossover box. Every connection point on the XO20. 1 Crossover is marked plus (+) or negative (-). Make a choice as to which lead is either positive or negative and make sure all connections are consistent with the marking. One mistake will put your system out of phase. D. 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. Remove both jumpers on the XO20. 1 Crossover. 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. If frequency specialized cables are used, connect them to their respective inputs. In either case the other ends are connected to the same amplifier channel. Repeat same procedure for the other channel. BI-AMPLIFICATION The MG20. 1 is conveniently arranged for hi-amplification. [. . . ] 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. A word of caution-when audiophiles discover the effectiveness of damping material, they sometimes overdo it (on the premise that if a little is good, more is better). [. . . ]
