How to connect the projector to the amplifier in wired?

How to connect the amplifier to the projector? I believe that this problem is indeed a big problem for those who are new to the projector. Here are two ways to connect the projector to the amplifier, wired connection and wireless connection.

Method of Wired connection

Wired connection
is to directly connect the amplifier with an audio cable, connect one end to the audio port of the projector, and the other end to the amplifier device. We need to buy the corresponding cable connection amplifier according to the interface owned by our projector. The more common ones are the s / pdif fiber interface, HDMI interface and 3.5mm audio interface, respectively corresponding to the use of optical fiber audio cable, HDMI cable and 3.5 audio line. Among them, the optical fiber interface and the HDMI interface are very obvious and will not be illustrated. Let's take a look at the 3.5 audio cable.

s / pdif optical fiber interface amplifier connection method:

1. Use s / pdif optical fiber audio cable to connect the projector to the power amplifier​
2. Switch the sound output mode of the projector.​

HDMI high-definition cable connection method:

1. Use HDMI to connect to the projector interface that supports arc return;​
2. Connect the other end to the HDMI interface of the power amplifier;​
3. Switch the sound output mode to hdmi (arc return) on the projector That's it.​

3.5 Audio cable connection method:

1. Connect the 3.5mm audio head of the 3.5 audio cable to the 3.5mm audio interface on the projector;​
2. Connect the red and white color lotus plugs to the color lotus interface​
If you are using an old-style projector with only a lotus interface, you only need to purchase a two-to-two lotus-head RCA audio cable and connect the corresponding color interface.

The advantages of wired connection: the sound quality is higher, and it can even be basically lossless by improving the quality of the audio cable.
Disadvantages of wired connection: a longer line is required. If the line is not laid in advance in the home, it can only be exposed outside or on the ground, affecting the aesthetics of the indoor environment.
