Page 4: Installation
INSTALLATION Because the MC8 dissipates very little heat (less than 10 watts) ventilation is not an important consideration, allowing great flexibility for custom or built-in installations. Of course, reasonable judgment must be exercised to see that the MC8 does not obstruct ventilation required by amplifiers or other equipment in the system. - Page 5 CONNECTION Low-gain phono input: This input provides the amplification and equalization required by moving-magnet and high-output moving-coil cartridges. The input impedance is the industry standard 47,000 ohms shunted by approximately 100 picofarads capacitance. This is well suited to nearly all moving-magnet and many high output moving-coil cartridges.

Page 6: Absolute Phase
GETTING THE MOST FROM YOUR MC8 The Motif MC8 offers an unparalleled level of sophistication and refinement in music reproduction, but it cannot transform an inferior stereo system. Only the very best amplifiers and loudspeaker systems will be capable of fully revealing the capabilities of this precision instrument. - Page 7 negative connections on either your cartridge or your speakers (be sure to reverse both channels). If you are not sure about the phase of every piece in your system, you can establish correct absolute phase by careful listening. When the system is in correct phase, transients will be noticably cleaner and more sharply defined.

Page 8: A Few Tips
A FEW TIPS Warm up the MC8 before listening: The sonic performance of the MC8 improves noticeably as the unit warms up. The midrange becomes more lucid, the highs smoother, and the soundstage expands. The warm up period can be expected to last several hours. -
