What is a Custom Audio Amplifier
Custom Audio Amplifier is a specific brand of audio amplifier. It is made by the renowned audio amplifier maker Custom Audio Electronics. Currently, Custom Audio Amplifier has four types of audio amplifiers.
Each of these audio amplifiers has different features that make them unique, hence producing distinct performances. Depending on what you want in your audio system, installing custom audio amplifiers will produce the desired sound effect and quality.
A typical custom audio amplifier is an electronic amplifier designed to enhance, improve, or amplify low-power electronic audio signals to the sound level that is sufficient for loudspeakers, whether in a home theatre gadget or vehicle.
For example, a custom audio amplifier picks up the audio signal from a radio receiver or audio player, or head unit. It then increases the audio signal to the point at which the loudspeakers can convert and produce a quality sound.
Generally, the custom audio amplifier has been used in various sound systems devices such as soundbars, public address systems, home audio systems, car audio systems, and musical instrument amplifiers like piano amplifiers.
Typically, a custom audio amplifier serves as the last electronic phase in a standard audio playback device before transmitting the signal to the loudspeakers for sound or voice release. Different custom audio amplifiers have various power capacities, especially for varying applications such as car audio systems, coach audio systems, and home theatre audio systems. The power grades of custom audio amplifiers are rated in watts and depending on the types of applications. The rating can be in tens, hundreds, or more to produce quality audio effects.
The implementation of a custom audio amplifier operates with transistors in linear mode to establish an output voltage similar to the input voltage level. Thus, the forward voltage gain is high primarily at a minimum of 40 dB going rate.
If the forward voltage gain is a feedback loop component, the total loop gain increases at a higher rate. Hence, the feedback in custom audio amplifiers becomes higher due to the high loop voltage gain, which enhances the output sound.
At the same time, the custom audio amplifier also tried to eliminate any form of distortion resulting from the nonlinearities in the forward path and lessen the power supply noise by boosting the power supply rejection.
Application of a Custom Audio Amplifier
Different types of custom audio amplifiers can be used or applied to various audio system devices. Custom audio amplifiers can be installed for Important applications like the public address systems, theatrical and concert sound reinforcement systems, and domestic systems such as stereo or home-theatre systems, certain huge musical instruments such as piano or electric keyboard.
In most situations for bigger audio systems, the custom audio amplifier is embedded into a sole amplifier headbox that comprises different components such as a preamplifier, tone controls, and electronic effects.
The custom audio amplifiers are often carefully installed in loudspeakers of the audio system, such as a wooden speaker cabinet, to produce an improved and quality sound effect.
Custom audio amplifiers can also be used by Disk Jockeys that want specific performance or need a powerful amplification with a specialized layout by adding a separate rackmount preamplifier, equalizers, and a custom audio amplifier placed in a high road stand.
In some cases, the custom audio amplifiers are used in standalone units, often utilized by individuals like hi-fi audio enthusiasts and manufacturers of public address systems (PA systems) and soundbar systems.
Many hi-fi sound user of custom audio amplifiers uses a stereo custom audio amplifier to bring together both sides of speakers and then create a single-channel (mono) custom audio amplifier to run a subwoofer at optimum performance.
It is understood that the number of custom audio amplifiers to be used in bigger places, such as a sound reinforcement setting, depends on the size of the stage or location. For example, a small eatery space only requires a single custom audio amplifier working with public address speakers.
On the other hand, a nightclub requires multiple custom audio amplifiers for the central speakers, including various amplifiers for other monitor speakers usually used by live artists or musical bands.
There may be a need for extra custom audio amplifiers working for the subwoofer for spacious nightclub spots.
Numerous custom audio amplifiers can be used or installed in different racks and large loudspeakers in stadium concerts. Additional cars and coaches also use custom audio amplifiers in their dashboard stereos, which are fully integrated inside the chassis of the main product.
