Wow, that company sure made themselves a target for sarcasm:
In any turntable installation, don't extend the audio wires and be sure to connect the ground wire to the chassis of the (pre)amp you plug into. Turntable wiring is of a particular length so that the wire's impedance and length deliver the proper frequency response to a Phono Preamp's input. And, of course, you'll need a Phono Input, which is not a line level input. The cartridge's signal is about 20 dB down and must be dramatically equalized for proper playback of records.
What do you mean by square on both sides? Squares are equal on all sides, but turntable plinths are rarely equal on all sides. If by square you mean 90 degree corners, that base looks like it has them.
