Illustration of how to connect the audio to the amplifier

Question 1: Illustration of how to connect the audio to the power amplifier. The power amplifier has an output port, usually one black and one red in a group, connected to a speaker. There will be two sets of 2.0 amplifiers connected to the left and right speakers. A 5.1 amplifier will have 6 sets of outlets, which are connected to the front, rear, left, right, center, and subwoofers. There are signs. Connect the corresponding speakers. It is best to use the same red port for connecting speakers. If a speaker is connected incorrectly or placed in the wrong position, the stereo effect will be completely destroyed.

If you send me a picture of the amplifier, I can explain it to you in detail.

Question 2: How to connect the power amplifier to the speaker. To be honest, this power amplifier is not suitable for pushing your speakers. Yours is a mono three-zone constant voltage broadcast integrated power amplifier.

It can Connect two for listening, the positive connection is 8 ohms of the power amplifier, and the negative connection is 70V or 100V, which is connected to a fixed-voltage broadcast speaker (there is a transformer on the constant-voltage speaker)

Question Three: How to connect this power amplifier to the speaker. In the second picture, the 2nd to 6th sets of coaxial ports in the upper row are for music input signals. The first set of REC can be connected to recording equipment, not signal input ports.

The top 4 sets of binding posts in the third picture are the main channel outputs, L is the left and R is the right. The power is the two groups with the largest output channels in the power amplifier. Just connect two speakers. . The red one is connected to the positive pole of the speaker, and the black one is connected to the negative pole. The output in the lower left corner is the center output, and the lower right corner is the surround output. The speaker connection method is the same as the main channel.

The fourth picture is just the power interface.

The maximum power of this amplifier is 100W, and the impedance is 8 ohms.

Question 4: Regarding the connection method between the audio, power amplifier and LCD TV, prepare a pair of audio cables, one red and one white, with one end plugged into the audio output socket of the TV and the other end plugged into the power amplifier Any set of audio input sockets (as shown below) is OK, provided that your two speakers and amplifier have been effectively connected with speaker cables.

Question 5: How to connect the power amplifier to the computer? How to connect the computer to the power amplifier? Use a 3.5MM cable with two lotus heads on the other end. The 3.5MM head is connected to the computer output (usually green, the one in the middle of the three holes That), connect the Lotus head to any group on the amplifier (note the corresponding white and red), such as the DVD input, and then just turn on the DVD input in the function.

Connection method:

1. Plug the 3.5MM head of the audio cable (as shown in the picture) into the computer output interface.

2. Plug the lotus heads into any set of inputs of the function. Pay attention to the corresponding red and white colors with the interfaces.

3. Open the set of inputs connected to the lotus head on the amplifier, such as DVD.

4. The computer plays audio.

5. The audio passes through the power amplifier and is transmitted to the audio equipment to produce sound.

Power amplifier, referred to as power amplifier, commonly known as "amplifier", is the most basic equipment in the audio system. Its task is to convert the weak electrical signal from the signal source (in professional audio system, from the mixer) Amplification is performed to drive speakers to produce sound.

Question 6: How to connect the power amplifier and speakers to the computer. How to connect the various interfaces of the AV power amplifier. How to connect the power amplifier and speakers to the computer.

Speakers with power amplifiers are called active speakers, and those without power amplifiers are called active speakers. speakers. The way to connect the active speaker to the computer is to use a cable with a 3.5 plug on one end and a double lotus plug on the other end. The 3.5 end is plugged into the headphone output of the computer, and the other end is plugged into the audio input end of the active speaker with a double lotus plug. When the speaker is powered on, adjust the volume knob of the speaker to control the volume. If a speaker without a power amplifier cannot be directly connected to the output of the headphones, the volume will be very low, and a power amplifier will be required.

How to connect various interfaces of AV amplifiers

"The three armies have not moved, food and grass go first." Before describing the connections, we will also talk about the various interfaces and wires connected to the amplifier. Now is the era of digital transmission, so we will only talk about digital transmission here, and we will not mention the analog aspect for the time being. The most popular one now is HDMI. In many new products, HDMI interface has become a standard configuration.

HDMI is a new generation of multimedia interface standard. Currently, there are HDMI 1.0, HDMI 1.1, HDMI 1.2, HDMI 1.2a, HDMI 1.3 and other specifications. The HDMI interface has become a must-have in the new generation of AV amplifiers. From the beginning of the HDMI 1.0 specification, the HDMI organization defined support for DolbyDigita 5.1 (including Dolby DigitalEX) and DTS (including DTS-ES). HDMI 1.1 adds the function of supporting DVD-Audio, and HDMI1.2 adds the SACD function. HDMI 1.3 adds support for the new lossless digital surround audio formats Dolby True HD and DTS-HD Master Audio, so if you want to enjoy true next-generation audio, you must choose an amplifier and player with HDMI 1.3 specifications.

In addition, HDMI (except version 1.0) can transmit 8-channel 192kHz, 24-bit uncompressed audio, which is better than all other consumer audio formats. Therefore, if the player can decode the audio format into multi-channel PCM, then it can transmit any of the above audio formats in the form of a decoded PCM stream. In this way, many older A/V receivers that support multi-channel PCM audio through the HDMI input can still be used to play the newer Dolby True HD and DTS-HD Master Audio formats.

Coaxial cable

In addition to HDMI, the transmission of digital audio signals mainly relies on two ways: digital coaxial cable using standard RCA interface and SPDIF optical fiber transmission. Both can achieve the goal of transmitting digital audio signals better. Coaxial cables have a relatively complete shielding layer, and the copper core in the middle is the channel for signal transmission. Using 75 ohm coaxial cables to transmit digital audio signals is a very mature and high-quality way. This interface standard has lower hardware requirements on the device side, but when transmitting high-frequency signals, relatively large attenuation is likely to occur, affecting the final sound quality. Compared with coaxial transmission, optical fiber has very strict requirements on the synchronization of the receiving and transmitting ends of the equipment, which is technically more difficult to achieve than coaxial transmission. However, the advantages of optical fiber technology in long-distance transmission are very obvious, and there will be no coaxial cable. The problem of excessive attenuation over long distances has made it favored by many users with distance restrictions and newly renovated users.

Connections between various high-definition players and next-generation power amplifiers

If you want to build a true theater of this generation, the power amplifier must support the HDMI 1.3a standard and support Dolby BTrueHD and DTS-HD MA and other decoding. There are currently many true next-generation power amplifiers, such as Denon AVR-4308, AVC-3808, AVC-2808, AVC-2308, etc.; Onkyo TX-NA905, TX-SA875, TX-SA805, TX-SR803, TX-SA705, TX -SA606X, etc.; Marantz SR7002 and SR8002; Pioneer VSA-AX1AH, Sony TA-DA5300ES, YAMAHA's RX-V1800, RX-V3800, etc.

Real next-generation power amplifiers generally have multiple HDMI 1.3 interfaces. For example, TA-DA5300ES provides six HDMI 1.3 inputs and one HDMI 1.3 output, so it is ideal for connecting to the entire home theater. Very convenient, for example, if you own a Blu-ray disc player, PS3, XBOX360... >>

Question 7: How to connect the red and white amplifiers to DVDs, set-top boxes, projectors, etc., above Connect the fiber optic coaxial cable, and then connect the middle speaker to the center surround, Pentium audio home theater.

Question 8: How should the amplifier + subwoofer + speakers be connected? Subwoofer connection: The power amplifier has a pre out. The English name below is SUBWOOFER. Use an ordinary audio cable, which can also be called an AV cable. (Audiophiles will use coaxial cables, but coaxial cables are more expensive and are generally used in high-end products. Audio equipment) There are two round holes below input 2 connected to Yamaha SW215 (L on the top, R on the bottom); just plug it into the L on the top. The subwoofer connection is complete. Speaker connections: SpeakerS behind the amplifier, below from left to right, main speaker right, main speaker left, center, surround right, surround left. Correspond to your 5 speakers, connect them one by one. Pay attention to the color of the speaker cable, red to red, black to black.

Question 9: How to connect speakers, amplifiers and computers. Thank you! I don't see what connector is on the other end of your black and white wire. I don’t know where the lotus plug you are looking at is connected. Usually the speakers of home music audio systems are passive (that is, they only have speakers), and the power amplifier is placed inside the audio host. The computer sound card outputs audio signals, which need to be amplified by a power amplifier and then output to the speaker (speaker). The speakers commonly used in computers are active, that is, the power amplifier is integrated into the speaker, so it only needs to receive audio signals from the computer to work. Because there is an internal power amplifier, it naturally needs to be plugged in. Generally, when a computer is connected to a home audio system, the audio is output to the audio input port of the audio host, and the audio host's power amplifier drives the passive speaker (speaker).

It seems that yours is a passive speaker and needs to be connected to a power amplifier to use it. The black and yellow wire is connected to the power amplifier. The black and white wire does not look like a power supply. It may be connected to the passive crossover output of the surround or center.
