Explanation of terms

Sampling frequency
Sampling involves taking a reading of a sound wave (analog signal) at
regular intervals and expressing the height of the wave at each reading in
digitized format (producing a digital signal).
The number of readings taken in one second is called the "sampling
frequency". The larger the value, the closer the reproduced sound is to the
original.

Speaker impedance

This is an AC resistance value, indicated in Ω (ohms).
Greater power can be obtained when this value is smaller.
Source direct
Playback with higher fidelity to the source becomes possible, as input
audio signals are output by bypassing the audio quality-control circuits
(BASS/TREBLE/BALANCE).
Protection circuit
This is a function to prevent damage to devices within the power supply
when an abnormality such as an overload, excess voltage occurs or over
temperature for any reason.
