With the changes of the times, people nowadays are under busy and stressful work, and the pace of life in many big cities is too fast, which can easily cause certain pressure.

Below, I will introduce to you what a Bluetooth amplifier is and how to connect the amplifier speakers to produce good sound.

What is a Bluetooth amplifier?

A Bluetooth amplifier is actually an amplifier with a built-in Bluetooth wireless receiver that can receive Bluetooth wireless signals from mobile phones. Generally speaking, this is the music signal. When using, turn on the Bluetooth switch of the mobile phone, then you can use the phone to scan nearby Bluetooth devices. After connecting to the Bluetooth amplifier, the music in the mobile phone can produce loud sound through the amplifier.

How to wire the power amplifier to get good sound

1. First, check the back of the amplifier and speakers to see if the audio cables are complete. If not, go to the hardware store to buy a section. It doesn’t have to be too long, otherwise it will be coiled up and placed at the back.

2. It is very easy to connect the audio cable. You can find a pair of pliers or scissors to peel off the rubber layer on the surface of the audio cable to expose the copper wire inside, which is generally two colors: brass and silver.

3. Peel off the skin, then twist the copper wire a few times by hand to make it harder. Then you will see red and black binding posts on the back of the amplifier. Connect the brass one to the red post and the silver one to the black post.

4. The other end of the audio cable is also connected to the back of the speaker. At this time, the speaker is a terminal type. Some are convenient and are snap-on type. Just press down the buckle with your finger, poke the wire in, and then let go. The wire will be clamped by the buckle, which is also very firm.

5. If you have two speakers, connect the wires on the Left and Right sides respectively, that is, connect one wire on each side.

6. After the power amplifier and speakers are connected, you need to input the sound source into the amplifier. Generally, a DVD player is sufficient as the sound source. If allowed, you can also use a laptop, which is more flexible. The connection cables need to use two audio cables with lotus connectors on both ends. Plug them into the L and R channels under OUTPUT on the back of the DVD to output the sound signal. Also plug them into the L and R channels on the amplifier, but make sure they are under INPUT. In this way, the sound will be output from the DVD to the amplifier, and then from the amplifier to the speakers.

7. Now you can turn on the DVD and amplifier, and you should be able to hear the sound. Below is the description of the buttons on the front panel of the amplifier. You can find a small flat-blade screwdriver, plug in the microphone, and slowly adjust the knob while speaking until the sound suits your voice and sounds comfortable to you.
