14 Plug and connection assignment
This chapter will help you select the right cables and plugs to connect your valuable
equipment in such a way that a perfect sound experience is ensured.
Please note these advices, because especially in ‘Sound & Light’ caution is indicated:
Even if a plug ts into the socket, an incorrect connection may result in a destroyed
power amp, a short circuit or ‘just’ in poor transmission quality!
Unbalanced transmission is mainly used in semi-professional environment and in hi
use. Instrument cables with two conductors (one core plus shielding) are typical rep‐
resentatives of the unbalanced transmission. One conductor is ground and shielding
while the signal is transmitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference, especially at
low levels, such as microphone signals and when using long cables.
