Corrosion and sound system terminals
Atmospheric corrosion can build up on speaker cable and interconnect
terminals over time. Should this occur, removing and re-inserting wires
and cables will improve the contact and hence the quality of signal
transmission. Always remember to turn off all equipment before
connecting or disconnecting any wires or cables.
Placement of components in your sound system
Lots of fresh air is important to the health of your electronics. The
louder you play your music, the more important it is to ensure that
components receive adequate ventilation. Amplifiers, in particular, will
generate a lot of heat. Placing the amplifier at the top of the stack, and
ensuring adequate ventilation, will help to ensure that the heat can be
dissipated as it should.
