Biamplification vs. Bridging Power Amplifiers: When seeking more output from a sound system, it is common to bridge the power amplifier to increase the power available and generate more output from the system.

Power Amplifiers in Bridge Mode: The maximum positive- and negative-voltage capability of a power amp is limited by the power supply's limits, i.e., its voltage rails. The amplifier can produce so many volts positive and negative at its output. The audio signal essentially swings between the positive and negative supplies within the power amplifier.

Using Single Supply Operational Amplifiers in Embedded Systems (PDF): Beyond the primitive transistor, the operational amplifier is the most basic building block for analog applications. Fundamental functions such as gain, load
isolation, signal inversion, level shifting, adding and/or
subtracting signals are easily implemented with this
building block.
