  • Page 4: Speaker Hook-Up & Usage

    4 LCR-750THX & Center-750THX FIGURE 1 SPEAKER WIRING LEFT RIGHT AMPLIFIER Both the LCR-750 and Center-750 are magnetically shielded. This means that they can be placed close to a television monitor without distorting the picture. If you place the speaker directly on top of a large screen direct- view monitor, there is some slight possibility of picture distortion.

    5 LCR-750THX & Center-750THX 5. THE M&K HIGH-FREQUENCY PRISM SYSTEM Your LCR-750 and Center-750 speakers utilize M&K's exclusive High-Frequency Prism System to optimize imaging and coverage of sound throughout the listening area. This system is designed to take into account the effect of the curved mesh metal grilles on your speakers.

    7 LCR-750THX & Center-750THX TIMBRE-MATCHING One of the most important factors in achieving excellent Home Theatre performance is timbre-matching. On film soundtracks, specific sounds are often moved from left to right or from front to back in the room. When the speakers reproducing these sounds have dissimilar characteristics, there will be an audible discontinuity when the sound shifts from one speaker to another.

  • Page 8: Satellite/Subwoofer Phasing Test

    8 LCR-750THX & Center-750THX If you mount the surrounds on the side wall behind the listening position, they can be aimed towards each other or angled towards the back wall or the side wall surface directly behind them. By reflecting sound behind the listening position, you may increase the sense of envelopment in the sound.

  • Page 9: Speaker Damage & How To Avoid It

    9 LCR-750THX & Center-750THX is correct. You need to perform this test because when Main speakers are located separate from a Subwoofer, each speaker is at a different distance from your ear. In some cases, the difference will be just enough so that the output from the Subwoofer arrives out of phase with the output of the Satellites.

    13. USE WITH M&K STANDS & BRACKETS The LCR-750THX and Center-750THX speakers contain threaded inserts on their back baffles. One set has two 1/4-20 inserts and the other a single 3/8" insert. You can use either of these to securely attach the speakers to an M&K LDM-75 stand, and M&K ST-series speaker stand, or M&K ST wall-mount brackets.
