Plug and connection assignment

This chapter will help you select the right cables and plugs to connect your valuable equip‐

ment 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 fits 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 hifi use.

Instrument cables with two conductors (one core plus shielding) are typical representatives of

the unbalanced transmission. One conductor is ground and shielding while the signal is trans‐

mitted through the core.
Unbalanced transmission is susceptible to electromagnetic interference, especially at low

levels, such as microphone signals and when using long cables.
In a professional environment, therefore, the balanced transmission is preferred, because this

enables an undisturbed transmission of signals over long distances. In addition to the conduc‐

tors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers

the signal, but phase-shifted by 180°.
