What is the plaque amplifier?
The board amplifier is a power amplifier that is built on a flat plate for installation inside the speaker. Like any power amplifier, the amplifier takes the signals at the line level and increases the level of their performance to control the speaker. Unlike the standard music amplifier, many plate amplifiers have a limited frequency response and comply with its typical use as a subwoofer amplifier. They are usually designed to be mounted inside the subwoofer cover, which is a specialized reproductor designed to reproduce bass and subsonic frequencies. While subwoofers purchased in the store include their own amplifiers, fans who build their own subwoofers have cut a hole on the back panel of their unit and screwed into it amplifier. This hides exposed plate components and leaves available controls and inputs. Usually a single connecna inner side of the plate amplifier is a few speaker terminals used to connect HLaon output amplifier with subwoofer controller.
Power rating for plate amplifiers varies greatly. While most of them are relatively powerful due to the large amount of energy necessary to control the subwoofer, their output power can range from approximately 80 to 500 watts in output power. One of the unifying functions is that while music amplifiers are trying to reproduce a frequency range from 20 to 20,000 Hertz to cover the entire range of human auditory and music tones, the plates amplifiers usually undress their response to frequencies of over 200 hertz. This limits them to use with subwoofers because they usually do not produce frequencies above 100 to 150 hertz.
Most boards amplifiers also contain a number of inputs and controls that are more sophisticated than the typical power of amplifier. Have crossovers that are used to remove higher frequencies from signals that amplifyAnd they usually allow the end user to change the active point of the crossover. Amplifiers can usually receive signals at the level of the loudspeakers at the level of the speaker, and then they can send these signals back to the component or speaker with the bass removed. Many boards amplifiers also contain phase or delay checks, allowing a bass signal to change better with the speaker system. Finally, they contain volume controls that make it possible to modify their output level to better connect with the reaction of the audio system.
