Useful Tips
The turntable should be positioned on a low-resonance surface such as wood
or multiple layer ply board to avoid structural vibrations disturbing playback.
Cartridge Replacement
1. Before replacement, put the stylus protector back on the stylus to
prevent damage to the stylus during the replacement process.
2. Carefully remove the wire leads from the original cartridge.
3. Loosen the two screws on the headshell that are securing the cartridge
and then remove the original cartridge.
4. Mount the new cartridge to the headshell and tighten it lightly. Do not
completely tighten the screws at this moment.
5. Connect the wire leads to the new cartridge's terminals. The wire lead
color codes are as below:
White Left channel positive (L+)
Black Left channel negative (L–)
Red Right channel positive (R+)
Black Right channel negative (R-)
6. Adjust the cartridge's position to make sure it is precisely aligned on the
headshell so that the stylus will be tracking the grooves in parallel
perfectly.
To achieve this, place the included paper cartridge alignment protractor
over the turntable spindle, carefully lift the tone arm and place the tip of
the stylus on the points marked 130mm and 250mm respectively. Fine
tune the cartridge's position on the headshell until the cartridge is
perfectly in parallel with the reference lines at both points.
7. Tighten the screws completely once the perfect alignment is achieved.
