Set the TURNTABLE BASE (1) on a flat, level surface free of vibration.Try to place the unit as far away from the speakers as possible. Keepthe unit away from direct exposure to the sun, heat, moisture or dirt.Keep the unit well ventilated. Use the turntable feet to horizontallystabilize the unit.2. Make sure that the VOLTAGE SELECTOR (3) switch (located on theTURNTABLE BASE) is set to the correct voltage. WARNING: If you tryto operate the turntable with the incorrect voltage setting, it can damageyour turntable.3. After checking to ensure that all packing materials have been removed,gently place the PLATTER (2) on the center spindle of the TURNTABLEBASE (1).4. Put the NEOPRENE MAT (4) on the PLATTER (2).CARTRIDGE INSTALLATION: (SEE FIG. 2)Because all cartridges have their own designs, please refer to yourparticular cartridge’s instructions to insure proper installation.1. Connect the lead wires to the cartridge terminals. For your convenience,the terminals of most cartridges are color coded. Connect each leadwire to the terminal of the same color.White (L+).............................................Left Channel +Blue (L-)...............................................Left Channel -Red (R+)................................................Right Channel +Green (R-).............................................Right Channel -2. Mount the cartridge in the HEADSHELL (5) and tighten it with thescrews included with the cartridge.ATTENTION STANTON 680 CARTRIDGE USERSWhen using a Stanton 680 or similar cartridge, where the body isgrounded to a cartridge terminal, remove the grounding strap fromthe cartridge body to the cartridge ground terminal. Failure to do thismay result in excessive hum.HEADSHELL INSTALLATION:Insert the HEADSHELL (5) into the front of the tubular TONE ARM (6).While holding the HEADSHELL firmly in a horizontal position, turn theLOCKING NUT (7) counter clockwise until the HEADSHELL is locked inplace.COUNTERWEIGHT INSTALLATION: (SEE FIG. 3)1. Slide the COUNTERWEIGHT (8) onto the rear of the TONE ARM (6)with the numbered stylus gauge facing forward.2. Twist the COUNTERWEIGHT (8) lightly counter clockwise, to screw itonto the rear of the TONE ARM (6).ADJUSTING HORIZONTAL ZERO (0) BALANCE ANDSTYLUS PRESSURE:1. Without touching the stylus tip, remove the stylus protector (if yourcartridge has a detachable one).2. Release the ARM CLAMP (9) and lift the TONE ARM (6) off the ARMREST (10).3. Counter clockwise advancement of the COUNTERWEIGHT (8) willcause the cartridge side of the TONE ARM (6) to be lowered. Clockwisewill cause the opposite. Turn the COUNTERWEIGHT clockwise orcounter clockwise as needed until the TONE ARM is balanced horizon-tally. You can easily tell this by watching for the point where the TONEARM “floats” freely.4. Place TONE ARM (6) on ARM REST (10) and lock it in place with theARM CLAMP (9).5. With the TONE ARM (6) locked on the ARM REST (10), hold theCOUNTERWEIGHT (8) steady with one hand while rotating theSTYLUS PRESSURE RING (11) until the numeral “0” on the ring alignswith the center line on the TONE ARM rear shaft. The horizontal zero(0) balance should be completed.6. Refloat the TONE ARM to ensure horizontal zero (0) balance. If zerobalance has not been maintained, repeat counterweight steps 3 - 5.7. After adjusting the horizontal zero (0) balance, turn the balancedCOUNTERWEIGHT (8) counter clockwise until the cartridgemanufacturer’s recommend stylus pressure appears on the STYLUSPRESSURE RING (11) where it meets the center line of the TONE ARM(6) rear shaft.ADJUSTING THE ANTI-SKATING CONTROL:Set the ANTI-SKATING CONTROL (12) to the same value as the styluspressure.
