question 1: what is the S/PDIF coaxial output? What do you mean? What's the use? How to use it? Digital coaxial audio output is used to connect high-grade power amplifier with digital decoding function, and middle and low-grade equipment does not have this function at all. Set the S/PDIF output, the amplifier to S/PDIF reception and the SPEAKER output to stereo

Question 2: How to connect the coaxial output to the audio equipment? As far as I know, the rambler 5.1 speaker has no coaxial input port, so it only has analog input, so it can't directly connect the coaxial output. If it has to be connected coaxially, it can only be connected to the dts decoder, specifically, the coaxial output is connected to the coaxial input of the decoder. It is a profound knowledge to connect dts decoder and speaker with three lotus wires. It needs to be understood slowly. It will be more efficient to concentrate everyone's wisdom and make yourself a master. I would like to recommend my favorite audio, hivi, Tanner, BT-audio AB HIFI suit, hivi and Tanner, which are obviously expensive and not suitable for computer audio. Although the sound quality is good, it is not proportional to the price of buying it. The BT-audio AB HIFI suit is much better, and its cost performance is very high. AB bookcase is a HIFI box with excellent comprehensive performance, which reproduces the classic and pure British sound. Using super instantaneous response unit, the treble is persistent, the bass is not sticky, the strong sound is not dry, and the weak sound is not empty. The warm and mellow sound shows the infinite charm of music, and you can feel the legendary and charming melody of the British sound, and enjoy the pedigree, sound quality and workmanship. The style contained in AB bookcase comes from the unique design of BT-audio audio engineer, and a bedroom and study desktop HIFI speaker is created with exquisite and elegant appearance. First-class workmanship and sound quality have created the myth of high-end and low price in the audio industry, and completely brought the concept of parity to the extreme! I believe it is a good choice for you

Question 3: What is the use of the coaxial output interface behind the TV? For most music lovers, the SPDIF output standard should be familiar. It is the abbreviation of (Sony/PHILIPS digital interface) Sony and Philips home digital audio interface, which can transmit LPCM stream and Dolby Digital and DTS surround sound compressed audio signals. SPDIF can be divided into coaxial and optical fiber from the transmission medium. In fact, the signals they can transmit are the same, but the carriers are different, and the interface and connection appearance are also different. However, optical signal transmission is a popular trend in the future, and its main advantages are that the interface is flexible and has stronger anti-interference ability without considering the interface level and impedance. COAXIAL SPDIF is generally called coaxial input, and it is marked by Coaxial on the back plate of the equipment. Digital coaxial interface adopts coaxial cable with impedance of 75Ω as transmission medium, which has the advantages of constant impedance, wide transmission frequency band and high-quality coaxial cable bandwidth up to several hundred megahertz. The time base error of digital coaxial transmission is very small, so this transmission mode has a good performance on sound quality. But when using, please pay attention to the impedance matching of transmission wire, and cooperate with 75Ω coaxial cable to ensure constant impedance and correct signal transmission. That is to say, in the matching of transmission wires, 75 ohm coaxial wires suitable for transmitting high-frequency digital signals should be used as the matching standard, which is commonly referred to as "digital wires". Generally speaking, the audio quality of coaxial terminal output and optical fiber output is similar. Therefore, some DVD players only set up digital coaxial output and omit the optical fiber output function.

Question 4: How does Haier TV use coaxial output? Hello, thanks for asking the enterprise.

Coaxial (digital audio and video output)

Step 1: You need to have a coaxial cable to connect the coaxial cable to the corresponding interface of the TV and the power amplifier.

Step 2: Set the power amplifier equipment and adjust it to the corresponding mode. The name and operation method of each power amplifier equipment are different. Please refer to the power amplifier manual for debugging.

You are welcome to ask questions to the enterprise again.

I wish you a happy working life ~

Question 5: What is the S/PDIF coaxial output interface used for coaxial transmission of audio signals? The coaxial transmission of audio signals is digital audio signals, and the sound separation is better, cleaner and more pleasant. The premise is that your playback equipment (DVD player, set-top box, computer) and audio equipment must have coaxial function.

question 6: how to connect the coaxial audio output of the TV set to the audio (1) the coaxial digital output is a digital signal. (2) Connect the coaxial input terminal of the audio decoder.

(3) Coaxial and optical fiber terminals can be converted by converters.

question 7: how to use the coaxial OUTput port of the upper motherboard, JSPDIF pin, pin 1, pin 3 and pin 5. definition: +5V, out, GND. The measured voltage of OUT in the middle is about 1V AC, which is directly output to the coaxial line through .1uF capacitor and 22-ohm series 1-ohm parallel decompression (TTL), and the sound quality is good.

the maximum working voltage of coaxial interface of s/PDIF is .5+/-.1V, that is, the maximum working voltage does not exceed .6V.. The voltage of the S/PDIF pin on the 78G motherboard is an ordinary TTL signal, and the maximum voltage is 1.5V, which is three times that of the former! Each motherboard is not exactly the same, so you can know how much V it is by measuring it with a multimeter AC file. The pin of my motherboard outputs 1.V, and a .1UF nonpolar capacitor is connected in series with the resistor to divide the voltage, which can solve < P > Question 8: How to connect the coaxial output of the smart TV to the coaxial interface of the power amplifier < P > After being connected coaxially, it is likely that the speaker of the TV will still make noise. At this time, you can turn the volume of the TV to or turn it to "mute".

Coaxial connection has no automatic shutdown function

Question 9: How to use coaxial connection power amplifier for LeTV TV? There are coaxial and optical fiber digital output interfaces under the back of LeTV TV, and use coaxial or optical fiber dedicated lines to connect to the power amplifier interface with coaxial or optical fiber input. A digital sound signal can be output. The sound setting item has an output selection digital output.

Question 1: Is there any way to use a TV with a coaxial output speaker without coaxial input? It depends on whether your speaker is an active speaker. Active speakers with amplifier boards all have signal input ports, and the ports are coaxial ports. The TV set and the active speaker are connected by coaxial line. Passive speakers don't have a power amplifier, and they need to be connected to a power amplifier to use, so there is no coaxial signal input. First determine whether the speaker is active or passive before use.
