THANK YOU for purchasing the Kronos Sparta turntable. The Sparta has been designed to produce the best sound reproduction possible from a vinyl record. It is built without compromise for this single purpose. It is a state-of-the-art hand built instrument. Each Sparta is individually constructed, assembled and tested to ensure years of musical enjoyment. It is important that you take the time to read this manual before assembling, installing and operating your Sparta. Assembly is simple, provided you follow all the necessary steps. Leveling of the turntable is particularly important. Once this is done, you will find the Sparta will not require frequent adjustments as it is a very stable platform. Of course, mandatory care must be given to setting up the tone arm and cartridge, as in any other turntable. Make sure you use a quality protractor to properly align the cartridge. Please keep in mind that your Sparta will need to settle for its first few days of operation. The self-learning speed guidance system will calibrate itself with use. After a few hours it will attain speed more quickly with a minimum of fluctuation. The micro-processor controlled speed adjustments are deliberately done in a slow and deliberate manner. This use of minimal power reduces motor induced vibration and hence optimum musical enjoyment. Enjoy.
