Assembly in bridge
The assembly in bridge is used in the world of the Amplificateur S audio.
It theoretically makes it possible to reach the quadrupling of the power of exit.
The objective of this type of very widespread assembly (also called bridge ) is to obtain a power raised starting from two small amplifiers, supplied with a Tension reduced and this to depends on consumption and the heat released.
Basic principle
Starting from a way (left or right), to apply the signal to 0° with the one of the amplifier like to 180° (opposition of Phase) to the second amplificateur.Thereafter it is enough to connect the High speaker to the high exits of each amplifier then to shunt the two masses between them.
Prérequis
-
to avoid any imbalance while using amplifiers in the same way standard.
-
the amplifiers must be able to face the doubling of their power of exit.
-
in certain cases it is necessary to intercalate a condenser at each exit of the amplifiers, all depends on the balancing of the unit.
