Speed Calibration - Avantgarde Magnum Bedienungsanleitung

5. Place the belt first round the platter, then round the smaller diameter of the pulley (33 1/3 rpm).
6. The tension of the belt can be changed by turning the
motor about its axis. The tension is correct if the correct
turntable speed is achieved within 10 seconds. If the
tension is too high, the motor could start to
vibrate a little bit. If the tension is too loose, the
turntable will not achieve a constant and correct speed.
7. If you have a hum noise in the platter bearing, please
ground the bearing with the
male plug in the hole of the bearing screw.
8. For mounting the tonearm and the cartridge, please use the special User manual for
your tonearm and cartridge!

4. Speed calibration

Install the drive belt, first around the platter, then around the motor pulley. There are two diameters on
the motor pulley:
• smaller for 33 1/3 rpm
• larger for 45 rpm
To correctly adjust the belt tension, turn the motor around its axis. Proper tension will be achieved
through eccentric placement of the motor pulley or if you have enough space on your platform, just
change the distance between the motor and the turntable chassis. The belt tension is correct if the belt
can be deflected by approximately ¾inch by a finger.
