Compare VU meter to peak meter PPM. Scroll down to related links and look at "VU meter - Wikipedia" and "Peak meter - Wikipedia".
db is decibel and in communication it is the amplifying factor where in audio it is the volume of the sound
To make low volume sound into HIGH volume sound.
It makes the sounds louder So it amplifies (increases in size/volume/sound) of the audio
A power amplifier increases the strength of audio signals, making them louder and clearer. This enhancement allows audio systems to produce higher quality sound with greater volume and fidelity.
ideally "line out" on the receiver to "audio in" on the amplifier, left and right... If there isn't a "line out" use the the "audio out" but keep the volume on the receiver relatively low to prevent overdriving the inputs on the amplifier.
You connect your audio leads to the 'aux' input on the amplifier, and the other end to your 'headphones' port. Don't turn up the volume too high on the computer, it will distort. Set the computer volume, so that distortion doesn't occur and then control the volume on the amplifier.
To connect a microphone to speakers, you will need an audio mixer or amplifier. Plug the microphone into the mixer or amplifier using an XLR cable. Then connect the mixer or amplifier to the speakers using audio cables. Adjust the volume levels on the mixer or amplifier to ensure proper sound output.
A Class T amplifier will typically cost around $20 to $40. The Class T amplifier is a small amplifier that produce a great amount of audio volume for it size.
A stock amplifier refers to the original audio amplifier that comes installed in a vehicle or audio system from the manufacturer. It typically provides adequate power and sound quality for standard listening needs but may lack the performance or features of aftermarket amplifiers. Upgrading to a more powerful or feature-rich amplifier can enhance sound clarity, volume, and overall audio experience.

dBm is defined as power ratio in decibel (dB) referenced to one milliwatt (mW). It is an abbreviation for dB with respect to 1 mW and the "m" in dBm stands for milliwatt. dBm is different from dB. dBm represents absolute power, whereas in audio engineering the decibel is usually a voltage ratio of two values and is used then to represent gain or attenuation of an audio amplifier, or an audio damping pad.
