After the speaker position is determined, install the speaker in place, and then connect the speaker wires. The left, center, right speakers and surround speakers are generally stuck wires, and some are terminal blocks. Make sure you distinguish between positive and negative, red, positive, black and negative. The cable is clamped tightly; the active subwoofer is directly connected to the power amplifier using the signal cable of the lotus head.

After connecting, you need to connect the signal. Connect high-definition TV boxes, DVDs, hard disk players and other playback devices to the HDMI input of the power amplifier, and connect the HDMI output of the power amplifier to the TV.

Use the speaker cable to directly connect the input terminal of the speaker to the output terminal of the power amplifier. It is important to make sure not to connect the reverse polarity, that is, connect the red terminal to red and the black terminal to black.

Introduction to audio equipment

In audio equipment, the wire is specially used to connect the power amplifier and the speaker. Since the speaker wire transmits power signals, there should not be too much wire on it. Signal loss, which objectively requires the speaker cable to have extremely excellent conductive properties.

Excellent electrical conductivity requires wires to have extreme transmission capabilities. The main technical indicators currently used to measure these two points are the N value and the number of wire strands. The N value is a parameter that reflects the purity of the metal used in the production of speaker cables.

OFC oxygen-free copper and tinned copper +/- are generally used and are easy to distinguish. Mainly used in various types of speakers, PA projects, home theater connections, and public space broadcast systems.
