LCD TVs and projectors, connected to 5 1 channel speakers, how many ways are there? What kind of cab

2,Of course**** video sign with HDMI,It's the best (1)If you realize the synchronization of the projector and TV,Three signals switch back and forth,You need to add (** two out)HDMI matrix,Function:Multi-channel signal in,Multi-channel signal out,You need three in and two out cross switching here,No need to manually unplug and unplug。 There is no three-in, two-out moment.

2) Another method is to manually unplug and unplug. 3. If the projector does not have HDMI, the DVI signal is preferred. 4, audio, buy an audio switcher, ** out of the way, but also more than one way useless.

HDMI、DVI、Chromatic aberration line,Arrangement,The former is preferred6,Speaker line selection:Go to the speaker store,Buy a professional speaker coaxial cable。 The pinky finger is as thick.

HDMI is high-speed, I personally like it, and it's very small, and it's very mini-audio, just use a coaxial cable.

1.Using an audio signal cable, the TV is connected to the speaker.

2.Only the left and right channels are output, only the main channel of the speaker is inserted, and the sound source is only two-channel.

The sound channel is Dolby surrounding,It is impossible for the TV to output this kind of sound source,It can only output stereo sound,It can be said,It can only be connected to the audio,The effect of not being able to connect。

The HDMI of the set-top box is connected to the HDMI of the projection with an HDMI cable, the optical fiber of the set-top box is connected to the decoder (you need to purchase this separately), and the decoder is connected to the speaker. If you're thinking about changing the speaker, just switch to one with an optical connector.

First of all, neither your projector nor the set-top box can directly output audio, so you need to convert.

Then,The diagram of the speaker is incomplete,Can't see whether it is active or passive,The difference between active and passive is whether the speaker should be plugged in,If you want to plug it in, it comes with a power amplifier circuit,It's called an active speaker。 Landlord, you seem to have a source.

If it's active, then you need this.

This optical fiber port is connected to the set-top box audio optical fiber interface, and the other side is connected to the sound with a lotus head one by one

If it's passive, the landlord needs a power amplifier with fiber optic input and output.

Mobile phones、TV is generally stereo output,The audio is generally decoded on the power amplifier,That is to say, stereo input,After power amplifier decoding,You can restore the effect of the sound channel,In the output of the mobile phone (generally the headphone jack,The kind) connect a connection line to the power amplifier input (the audio output of the computer is also such an interface)

The TV is generally a lotus socket to output audio, and this cable is required to connect to the power amplifier.

After connecting, you can use the power amplifier to decode the audio of your mobile phone or TV and restore the audio channel.

Thank you for answering your question, the person who became a brick family. It doesn't matter if you are a brick home, I always want to help you, the channel can be connected to the TV and mobile phone, because, there are R, L channels in the channel channels, R, L channels, which are the channels used by ordinary TVs or mobile phones. As long as the R and L channels can be found, they can be connected to a TV or mobile phone, and the other three channels can be left empty, regardless of it.

Generally, it depends on what interface signal your channel inputs. Nowadays, many of them directly use the left and right channels to simulate the outgoing channels, and some are Dolby decoding and the like.

Ordinary multi** audio is not so advanced, as mentioned above, analog.

Connecting speakers to a projector is a simple but important technology that allows you to improve your acoustics and hear clearer audio from your projector. If you need to connect your speakers, there are some simple and effective ways to do it. Here are some examples:

The first method: use an audio cable.

This is the most common method to connect the speaker to the projector using an audio cable. An audio cable is a standard audio cable that can be connected to most speakers. You only need to plug one port into the audio output port of the projector, and the other port into the audio input port of the speaker Li Xiaoshi.

The first two ways to argue: use HDMI-ARC

HDMI-ARC is a new HDMI standard that allows audio and signal to be transmitted over the same HDMI cable. If both your speaker and projector support HDMI-ARC, simply connect the projector and speaker together and enable HDMI-ARC in the settings options. This will allow the audio signal to be transmitted from the projector to the speaker, resulting in clearer sound.

The third method: use Bluetooth connection.

If your projector and speaker both support Bluetooth connectivity, it's easy to connect them. Just enable the Bluetooth connection function of the projector and speaker, and then select the speaker as the audio output device in the projector. This will allow the audio signal to be transmitted into the speaker via Bluetooth, resulting in better sound.

To sum up, these methods are the most common ways for speakers to connect to a projector. Not only are they simple and easy to use, but they can also enhance the sound effects of your videos and videos, allowing you to enjoy better results when you are in a movie or presentation.

Pick it up like this. 1.First, you make sure that the power supply to these devices is already plugged in.

2.Generally, there are two audio outputs of the set-top box, one is connected to the projector, and the other is connected to the TV.

3.The audio output of the set-top box is connected to your power amplifier input, and the power amplifier output is then connected to your audio, if the power amplifier does not support the output, there is no way, but it can be stereo.

That's it. Hope!

The TV is ordinary stereo and cannot be used. If you really want to connect, it is best to use a dedicated audio cable.

It refers to other sounds other than human language, including the sound of the natural environment, the sound of animals, the sound of machine tools, and various sounds made by human movements. The sound probably includes a set of power amplifiers, peripheral equipment (including limiters, effects, equalizers, VCDs, ***, etc.), speakers (speakers, speakers), mixers, microphones, display equipment, etc. Among them, speakers are sound output devices, speakers, subwoofers, and so on.

A speaker includes three kinds of speakers: high, low, and medium, but not necessarily three.

The development history of technology can be divided into four stages: electron tubes, transistors, integrated circuits, and field effect transistors.

The TV is ordinary stereo and cannot be used.

Connection: 1 (active.) Audio) If there is only one set of inputs, buy a 1-to-2 head and connect it directly to the TV and ***, it is better to have a redundant;

2.(Passive audio, with amplifier equipment), connection:

Connect the power amplifier input, the TV is connected to the power amplifier input, and you can connect any radio *** or something;

The audio is connected to the output of the amplifier. It is best to use a dedicated audio cable for the cable, but you can also use a regular cable without it.

Basically, TVs can only be connected to 2 channel outputs, if you want to give full play to the function of the channel, you need to put the source (***, Blu-ray machine, code flow meter, computer) through HDMI, 3 groups of analog lines (AC-3), digital coaxial (S PDIF) or optical fiber output to the power amplifier (or the corresponding interface of the active speaker), in order to output to the 6 channels.

If your speaker has Dolby decoding, you can also achieve the sound field effect of the channel by only entering the left and right channels. If it's an ordinary amplifier, you can't help it!
