Illustration of how to connect an audio amplifier

Question 1: How to connect the audio to the power amplifier diagram? The power amplifier has an output port, usually one black and one red, followed by a speaker. 2.0 There will be two groups of power amplifiers connected to the left and right speakers. A 5. 1 amplifier will have six groups of outlets, which are connected to the front, rear, left and right, medium and subwoofer respectively. There are signs. Connect the corresponding speakers. The red port is best connected to the red port of the speaker, which should be consistent. If a speaker is connected wrong or put in the wrong position, it will completely destroy the stereo effect.

If you send a picture of the amplifier, I can tell you in detail.

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

You can connect two auditions, the positive electrode is 8 ohms and the negative electrode is 8 ohms.

70V or 100V is connected to a constant-voltage broadcast speaker (there is a transformer on the constant-voltage speaker).

Question 3: How is this amplifier connected to the second row of coaxial ports in the second picture of the speaker? The second to sixth groups are connected with music input signals, and 1 group REC can be connected with recording equipment instead of signal input ports.

In the third picture, the top four groups of terminals are the main channel output, L is left, R is right, and the power is the two groups with the largest output channels in the amplifier. Just connect two speakers. Red is connected to the positive pole of the speaker, and black is connected to the negative pole. The output in the lower left corner is center center output, and the output in the lower right corner is sur surround sound output. The connection method of the sound box is the same as the main channel.

The fourth picture is just the interface of the power supply.

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

Question 4: Regarding the connection method of audio, power amplifier and LCD TV, prepare a pair of red and white audio cables, one end of which is plugged into the audio output docking station of the TV, and the other end is plugged into any set of audio input jacks of the power amplifier (as shown below), so that's ok, provided that your two speakers and the power amplifier are effectively connected by speaker cables.

Question 5: How to connect the power amplifier to the computer? How to connect the computer and the power amplifier? Use a 3.5mm cable with two shower heads. The 3.5MM head is connected to the computer output (usually green, the one in the middle of the three holes), and the lotus head is connected to any group of power amplifiers (note that white and red correspond), such as DVD input, and then the DVD input is turned on functionally.

Connection method:

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

2. Insert the showerhead into any set of inputs of the function respectively, and pay attention to the corresponding relationship among red, white and interface.

3. turn on the set of inputs inserted by the shower head on the power amplifier, such as DVD.

4. The computer plays audio.

5. Audio is transmitted to audio equipment through power amplifier.

Power amplifier, commonly known as "amplifier", is the most basic equipment in audio system. Its task is to amplify the weak electrical signal from the signal source (from the mixer in the professional sound system) and drive the speaker to make sound.

Question 6: How to connect the audio of the power amplifier to the computer? How to connect the AV power amplifier to various interfaces? How to connect the audio of the power amplifier to the computer?

A speaker with power amplifier is called an active speaker, and a speaker without power amplifier is called a speaker. The way to connect the active speaker to the computer is to use a cable with a 3.5 plug at one end and a double lotus plug at the other end. 3.5 The plug is plugged into the headphone output of the computer, and the other double lotus plug is plugged into the audio input end of the active speaker. Turn on the speaker power and adjust the speaker volume knob to control the volume. If a speaker without a power amplifier can't directly connect the output of headphones, the volume will be very low, so it is necessary to add a power amplifier.

Connection methods of various interfaces of AV power amplifier

"the three armies have not moved, and the food and grass are first." Here, before talking about the connection, let's talk about the various interfaces and wires connected by the power amplifier. Now is the era of digital transmission. Here we only talk about digital transmission, not analog for the time being. Now the most popular is HDMI. In many new products, HDMI interface has become a standard configuration. HDMI is a new generation multimedia interface standard. At present, there are many specifications such as HDMI 1.0, HDMI 1. 1 .2, HDMI 1.2a, HDMI 1.3, etc. HDMI interface has become a necessary interface for a new generation of AV power amplifier. Since the HDMI 1.0 specification, the HDMI organization has defined the support for DolbyDigita 5. 1 (including Dolby DigitalEX) and DTS (including DTS-ES). While HDMI 1. 1 adds the function of supporting DVD-Audio, and HDMI 1.2 adds the SACD function. HDMI 1.3 adds support for new lossless digital surround audio formats Dolby True HD and DTS-HD Master Audio, so if you want to enjoy the real next-generation audio, you must choose the HDMI 1.3 power amplifier and player.

In addition, HDMI (except version1.0) can transmit 8-channel 192kHz, 24-bit uncompressed audio, which is better than all other consumer audio formats. Therefore, if the player can decode an audio format into a multi-channel PCM, it can transmit any of the above audio formats in the form of a decoded PCM stream. In this way, many old A/V receivers that can support multi-channel PCM audio transmission through HDMI input interface can still be used to play updated Dolby True HD and DTS-HD main audio formats.

coaxial-line

Besides HDMI, the transmission of digital audio signals mainly depends on two ways: digital coaxial cable with standard RCA interface and SPDIF optical fiber transmission, both of which can achieve the purpose of transmitting digital audio signals well. Coaxial cables have relatively perfect shielding layers, and the copper core in the middle is the signal transmission channel. Using 75 ohm coaxial cable to transmit digital audio signals is a very mature and high-quality way. This interface standard does not require much hardware, but it is easy to cause great attenuation when transmitting high-frequency signals, which will affect the final sound quality. Compared with coaxial transmission, optical fiber has strict requirements on the synchronization time of receiving end and transmitting end of equipment, which is technically more difficult to realize than coaxial transmission. The advantages of optical fiber technology in long-distance transmission are very obvious, and there will be no problem of excessive attenuation of coaxial cable in long distance, so it has also been favored by many users with distance restrictions and new decoration.

Connection between various HD players and the next generation power amplifier

If we want to build a real cinema of this generation, the power amplifier must support the HDMI 1.3a standard, Dolby BTrueHD, DTS-HD MA and other decoding. At present, there are many real next-generation power amplifiers, such as Tianlong AVR-4308, AVC-3808, AVC-2808 and AVC-2308. Joan TX-NA905, TX-SA875, TX-SA805, TX-SR803, TX-SA705, TX-SA606X, etc. Marantz SR7002 and SR8002；; Pioneer VSA-AX 1AH, Sony TA-DA5300ES, Yamaha RX-V 1800, 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 1 HDMI 1.3 outputs, which is very convenient to connect the whole home theater. For example, you all have Blu-ray disc players, PS3 and Xbox 360>>.

Question 7: How to wire the amplifier audio? Illustration: Connect DVD, set-top box, projector, etc. It has coaxial optical fiber, surround intermediate and indirect speakers, and Pentium audio home theater.

Question 8: How should the amplifier+subwoofer+stereo be connected? Subwoofer connection: the power amplifier has a pre out, which is called subwoofer in English. It uses an ordinary audio line, which can also be called an AV line. (Enthusiasts will use coaxial cable, but coaxial cable is more expensive and is generally used in high-end audio equipment. ) Yamaha SW2 15 has two circular holes (upper L and lower R) under the input 2; Just plug it into the L above. The subwoofer connection is complete. Speaker connection: the speaker behind the power amplifier is surrounded from left to right, the main speaker is right, and the main speaker is left, centered, right and left. Connect your five speakers one by one. Pay attention to the color of the speaker wire, red to red, black to black.

Question 9: How to wire the speaker amplifier computer? Thank you! I can't see what connector is at the other end of your black and white line. I wonder where the lotus plug in your hand is connected? Usually, the speakers of home music stereo are passive (that is, only speakers), and the power amplifier is in the audio host. The output of computer sound card is audio signal, which needs to be amplified by power amplifier and then output to speaker (sound box). The speaker commonly used in computers is active, that is, the power amplifier is integrated in the speaker, so it can work only by receiving the audio signal of the computer. Because there is a power amplifier inside, it is natural to plug in the power supply. Generally speaking, when the computer is connected to the home stereo system, it outputs audio to the audio input port of the audio host, and the passive speaker (speaker) is driven by the power amplifier of the audio host.

It seems that yours is a passive speaker, and you need to connect a power amplifier to use it. The black and yellow wires are connected to the power amplifier. Unlike power supplies, black and white wires can be connected to passive frequency division outputs that surround or center.
