Q : What is bridging? What is the use of bridging?
A : In professional amplifiers, Bridge mode refers to bridging between channels and channels. For example, if the left channel and the right channel are bridged, then the power of the power amplifier is theoretically increased by 4 times. Actually, there is loss in the bridge and energy conversion. The power is about 2.5-3 times that of the stereo. The size of the power supply current provided by the amplifier.
After the bridge, you can push the speaker with more power. In other words, the bridge can increase the power. At this time, you must pay attention to the impedance, power and polarity of the speaker. Otherwise it will burn out the speakers or amplifiers.
A power amplifier with a bridge mode is more flexible and can be used for emergency if necessary, but it is recommended to use it under the guidance of a professional.
