How to connect the projector with the stereo?

Question 1: How do I connect the projector and the stereo? You should use HDMI cable to connect to the projector, right? If your projection has a sound loop-out interface, you can use four cables (audio cables) to directly connect the sound input interface of the power amplifier, if the projection does not have an audio loop-out interface. A power amplifier with HDMI input and output is also available. If the power amplifier has no HDMI input and input interface, there is no choice but to change the power amplifier or buy a converter (HDMI input, DVI and audio output).

Question 2: How to connect the projector to an external speaker? If an external active speaker is connected, connect the audio output of the projector to the audio input of the speaker with a signal line. (Analog signal is the line of double shower head)

Question 3: How to connect the projector to the speaker 10 minute audio output, which is the earphone interface of the computer. Connect your speaker with 3.5 turns of lotus wire (the specific situation depends on your speaker interface).

Question 4: How to connect the projector to the audio projector can connect the audio.

The projector was originally just a video display terminal. For the convenience of customers, a low-power speaker was built in.

If you don't need to use the built-in speaker of the projector, you must first have an audio system outside the projector;

Your video equipment (computer/mobile phone /dvd, etc.). ) just connect the video port (hdmi/VGA/S-VIDEO, etc.). ) When connecting the projector, then connect the audio output of the video device to the input of your audio device.

When connecting audio, you need to pay attention to choosing the appropriate port and cable. The audio output of computers and mobile phones is 3.5mm stereo plug, the audio output of DVD is RCA Lotus plug, and the audio input of projector is generally RCA Lotus plug. Therefore, the audio connection of computers, mobile phones and projectors should use cables with 3-core 3.5mm plugs on one side and red and white lotus plugs on the other, and the audio connection of DVD and projector should use cables with red and white lotus plugs on both sides.

Question 5: How to connect the projector to the amplifier audio 1? The projector is connected to the jukebox, and the connecting line between the projector and the jukebox is hd line or SD line. If the projector does not have a high-definition interface, please purchase an adapter from high-definition to VGA separately.

The connecting line between jukebox and amplifier is a red and white AV audio line.

3. The connecting line between the power amplifier and the audio is the speaker cable, and the signal output interface of the power amplifier is output. Please match the color of the wire with the power amplifier interface.

Question 6: How does the projector connect external sound? What do you need? I guess your projector has no speakers. Maybe you think it's not enough to make a sound.

Some projectors have RCA signal output port, which can be connected to the input end of power amplifier. But I don't understand what's the use of connecting the stereo to your projection.

The following links may be more suitable for you, please refer to them!

The normal connection is:

An audio source (such as a Blu-ray player) is connected to the power amplifier HDMI IN, and the power amplifier HDMI OUT is connected to the projector.

On most power amplifiers, several devices connected with HDMI can also be linked by setting. If the power amplifier is turned off, the projection is turned off, and the power amplifier and other devices are turned off. This connection is very convenient.

Question 7: How to connect the projector sound? The projector is connected to the computer, not the projector.

The projector is equivalent to a display with different structures. It only needs to connect the video signal to the computer, and the notebook or computer outputs sound. In most cases, it is directly replaced by computer multimedia speakers.

If you need to amplify the sound of a large conference room, you can install multiple speaker systems in series and parallel and connect them to the multimedia speaker output interface.

Question 8: The connection mode of projector and stereo is 10. You'd better ask someone to arrange such a thing. Audio equipment can be used independently. Connect the data cable to the sound card of the computer, and then connect the speaker to the audio signal output port (power amplifier or frequency shifter with power amplifier). Projection requires a display signal distributor, and a data cable is used to connect the computer graphics card with a port of the distributor. Then, the other output port of the distributor is connected with the input port of the projector using a data cable. Pay attention to the plug type of data cable, including the pin (male) and hole (female) inside, and pay attention to the length of data cable. The projector, stereo and computer need independent power supply, and they are plugged into the socket respectively or the power cord is extended with plugs and plugged into the socket. If it is a classroom, conference room and other places that need projection, you can put the computer host and audio together, and then you need to connect various wires.

Question 9: Can the projector be directly connected to the stereo? Which interface is connected? The projector is not allowed to receive audio signals.

The solution is too simple.

Your laptop is connected to the projector through a VGA cable to output video.

The notebook computer connects the earphone jack of the computer with a 3.5-turn double lotus cable, and then outputs the audio signal to the power amplifier.

Question 10: How to connect the projector and external audio? If an external active speaker is connected, connect the audio output of the projector to the audio input of the speaker with a signal line. (Analog signal is the line of double shower head)
