What is a dual amplifier?

also known as a two -channel or stereo amplifier, dual amplifier is an audio component that can take two mono inputs at the line level and increase their output levels to control two separate speaker systems. Dual amplifiers were historically popular as a means of amplifying two -channel stereo signals and remain useful in multi -channel audio systems. While the term “dual amplifier” is most common in professional sound circles, two -channel amplification tools remain predominant in domestic and automotive audio systems. This has the advantage of both economical space and cost reduction compared to Mono amplifiers, as some components can be shared. On the other hand, it has the potential to introduce compromises in sound quality, because two separate signals mixed together increase the potential for signal leakage together and cause distortion. Vset of a single power supply between two channels may lead to a lack of energy if both channels experience a peak withou time.

The term "dual amplifier" is very common in a professional sound world where it is used to describe public address amplifiers (PA) and speakers amplifiers. It is also popular in an audio car, where dual amplifiers often supply energy to two subwoofers in a system for maximizing bass response. In domestic audio applications, this term is more rare, although it is often used to indicate dual mono designs that try to generate a larger separation between the two channels than the standard stereo amplifier.

with continuing popularity of spatial, double amplifiers face competition from multi -channel amplifiers. Domestic cinema enthusiasts can buy amplifiers that contain five or seven channels of amplification in one, large, Company. Although these amplifiers have the advantage of being in a single box, they also have a disadvantage that they have more channels in the box with parallel RIzik of interference and crosses. Audiophiles often avoid dual or multi -channel amplifiers for monoblock amplifiers that contain only one channel of amplification and do not create any risk of interference between channels.

Dual amplifier components have the advantage over monoblock amplifiers in applications where sound quality is a primary problem. Very top audio systems use a technique called Bi-Amping, in which one sound channel is divided into high and low frequencies. Separate amplifier channels send a high -frequency signal to the speaker and a low -frequency signal to the speaker. Theoretically, this provides better sound quality by circumventing the speaker crossover and by maintaining two different signals separate. In these applications, dual amplifier serves the same role as the Mono amplifier in a system that is not two amlated.
