Bridging
is a connection method for professional audio amplifiers - Bridge Mode.
Briefly,
the bridge of the amplifier is to connect the two outputs to a set of loads
(speaker or speaker system) at the same time. Increase the output voltage of
the amplifier (won’t distorted audio) to increase power. Let's learn this Magical Operation together!
1. Early power amplifier products, due to the limitation of component
parameters, single channel can not achieve high power output, and the bridge
mode can meet the demand for high power output;
2, Power amplifier single channel power is not enough to promote
high-power size speakers (such as dual 18-inch ultra-low speakers), you need to
use the bridge mode to meet the high power requirements of the speaker;
3, In order to save costs, the greater the power of the single channel,
the more expensive the amplifier. Use bridge mode to meet high power output
while reducing costs;
4, Live performances too large, large number of speakers and high power
demand, when the environment is special, will promote the use of multi-bridge
mode high-power speakers.
1, We must understand that the bridge is used when the power of the
amplifier is not enough to load the sound. Usually, this connection is not
stable, so it is not recommended!
In theory, the power is doubled, but the user has neglected a very important problem: in theory, the power amplifier bridge refers to the fact that the technical parameters of the two channels are completely equal, but it is practically impossible, even The world's top power amplifiers are also difficult to achieve.
Therefore, when bridging, the power mismatch causes the speaker to burn (or the amplifier burns), and the first is still the crossover distortion and the imbalance of the parameters of the two channels.
