Sound Quality

As we all know, the capacitor (C) and the inductor (L) form an LC circuit on the audio circuit for frequency division. When the audio signal of the power amplifier passes through the LC circuit, it will be separated according to the frequency division point and sound channel of the initial design. High and low frequency signals are sent to different speakers.

From the simplest two-way frequency: high/bass, three-way frequency: high/medium/bass, advanced four-way frequency: high/medium/low/super bass or super high/high/medium/bass, to many advanced Five-way frequency: super high/high/medium/low/super bass.

In the selection of components, from the most basic 1 capacitor and 1 inductor, 2 capacitors and 2 inductors, to multiple capacitors and multiple inductors. When the signal passes through the capacitor, its phase is reversed by 90 degrees (ignoring the loss of the capacitor itself), and when the signal passes through the inductor, its phase advances by 90 degrees. Generally, for complete frequency dividers, each sound channel uses the same number of capacitors and inductors. For those who have special requirements for sound quality, the sound from the power amplifier to the speaker must pass through the LC frequency divider circuit, so the importance of capacitance and inductance to sound is self-evident.

If you want the frequency divider of the frequency divider to be accurate, the capacitance value of the capacitor must be relatively accurate. Therefore, the capacitance tolerance of used on the frequency division circuit must be accurate.After decades of development, our domestic electronic parts manufacturing can fully meet the needs of users in terms of manufacturing product accuracy. For conventional products, the capacitance tolerance is controlled within ±10% ±5%, especially some with high accuracy requirements of ±2 % ±1% can also be done.
