In this article, we will delve into the world of bridge mode, exploring its benefits, limitations, and applications.
What is Bridge Mode in an Amplifier?
Bridge mode, also known as bridged mode or bridging, is a configuration in which two or more amplifier channels are combined to produce a single, more powerful output. This is achieved by connecting the positive terminal of one channel to the negative terminal of another channel, creating a bridge-like configuration. The resulting output is a single channel with a higher power rating than the individual channels.
How Does Bridge Mode Work?
To understand how bridge mode works, let’s consider a simple example. Suppose we have a two-channel amplifier, each channel rated at 100 watts. When connected in bridge mode, the two channels are combined to produce a single channel with a power rating of 400 watts. This is because the two channels are working together to produce a single output, rather than two separate outputs.
The process of bridging two channels involves the following steps:
- The positive terminal of one channel is connected to the negative terminal of the other channel.
- The negative terminal of the first channel is connected to the positive terminal of the second channel.
- The resulting output is a single channel with a higher power rating than the individual channels.
