7.4. Connection with different power speakers on the 100V speaker line
This connection example uses the output transformer
AD320/30
which allows to exceed the 30mt
limit of cable between the amplifier and the speakers suitable to be connected to the 100V line
such as horn loudspeakers
AD330/15T
and
AD330/40T
and the rectangular or round speakers
AD332/60T
and
AD333/30T
.
In this case, the amplifier behaves as if it were a small power plant that supplied the 100V speaker
line.
Individual speakers will then determine how much power to take from the line. By connecting a 5W
speaker to the 100V line will be reached a certain sound intensity, using a 10W speaker will be
more power intensity.
All our loudspeakers are equipped with a commutator/selector or several connection terminals in
order to pick up different power levels from the line and adapt the sound intensity to the area that
has to be sounded.
The important thing is not to exceed the maximum power supplied by the amplifier in order not to
overload it. For example if speakers using the 10W socket are connected, it is not possible to
connect more than 3, but if the 5W socket is used then it is possible to connect up to 6.
It is also possible to use combinations, for example two speakers connected to 10W and two
speakers connected to 5W. Obviously the speakers connected to 5W will produce a lower sound
intensity.
