How to plug in the power amplifier cable

1. Connect the black wire of the speaker to the red interface of the power amplifier, and the black and white wires to the black socket of the power amplifier. If it is convenient to open the back cover of the speaker, it is best to open the back cover and actually check the wires on the speaker interface inside. The wire connected to the "+" level should be connected to the red interface of the power amplifier.

2. The knobs on the front panel of the amplifier (from left to right) include input signal selection control, subwoofer volume control, reverberation depth adjustment, microphone treble adjustment, microphone bass adjustment, microphone volume control, whole machine power switch, microphone input socket 1, microphone input socket 2, surround sound volume control, center channel volume control, main channel bass control, main channel treble control, main channel left and right balance control, main channel volume control, equal loudness selection or bridge selection switch.

What are SR and FR of power amplifier?

The FL, FR, SL, and SR on the rear jack of the amplifier are:

SL stands for left surround, SR stands for right surround, FL stands for main left channel, and FR stands for main right channel.

There is also CEN for center and SW for subwoofer.

The power amplifier is commonly known as the "amplifier". Its function is to amplify the weak signal from the sound source or the preamplifier to drive the speaker to make sound. A good sound system plays an indispensable role in the power amplifier. The power amplifier can be generally divided into three categories: "professional power amplifier", "civilian power amplifier" and "special power amplifier".

What is the aux jack on the amplifier?

The AUX interface behind the power amplifier or speaker refers to the audio input interface, which can output the audio of electronic audio devices including MP3 (general headphone jack), and can output the music in these devices through the car's audio system.

AUX interface usage:

Aux, which is the abbreviation of "Auxiliary", is an additional signal line design. In general audio equipment, in addition to the formal output and input terminals, there are often several input and output terminals marked with "Aux".

The input/output terminals marked with "Aux" are used as spare terminals. In special applications, such as when additional sound output or input is required, this terminal can be used. This spare terminal or line, regardless of input or output, is collectively referred to as Aux.
