Points to Remember
In all cases, use good quality twin screened audio cable. Check for instability at the output.
Always connect both conductors at both ends, and ensure that the screen is only connected at one end.
Do not disconnect the mains earth from each piece of equipment. This is needed to provide both safety and screen returns to the
system star point.
Equipment which has balanced inputs and outputs may need to be electrically isolated from the equipment rack and/or other
equipment, to avoid earth loops.
It is important to remember that all equipment which is connected to the mains is a potential source of hum and interference and
may radiate both electrostatic or electromagnetic radiation. In addition, the mains will also act as a carrier for many forms of RF
interference generated by electric motors, air-conditioning units, thyristor light dimmers etc. Unless the earth system is clean, all
attempts to improve hum noise levels will be futile. In extreme cases there will be no alternative but to provide a completely
separate and independent `technical earth' to replace the incoming 'noisy earth'. However, always consult your local electricity
supply authority to ensure that safety regulations are not being infringed.
