Anonymous users2024-02-15The meaning is whether it is grounded, lift is not grounded, norm is grounding, and it is generally used to solve the noise problem caused by grounding.
A class of amplifiers in which none of the power output components of the amplifier have a current cut-off (i.e., stop the output). Class A amplifiers operate with high heat and low efficiency, but have the inherent advantage that there is no crossover distortion. Single-ended amplifiers are all Class A working methods, and push-pull amplifiers can be Class A, Class B, or Class A and B.
Class A and B power amplifiers are bounded between Class A and Class B, and the on-time of each "arm" of push-pull amplification is greater than half a cycle of the signal and less than one cycle. Class A and B amplification effectively solves the problem of crossover distortion of Class B amplifiers, and the efficiency is higher than that of Class A amplifiers, so it has been widely used.

The second is stereo and bridging mode selection. In stereo mode, the two channels of the amplifier work independently. In bridged mode, the amplifier works in bridge mode, where the two channels push the forward and reverse signals respectively to increase the output power, and you need to connect the two red binding posts to the speakers.
To put it bluntly, it is to merge two channels into one. I don't know if you understand when I say that.

Anonymous users2024-02-10Summary. The small switch on the back of the amplifier is usually a power selector switch or a working mode selector switch. The exact usage may vary from model to model, please check the manual of the amplifier you are using to understand its specific purpose.
In the case of a power selector switch, there will usually be two options: power or manual. In power mode, the amplifier will automatically turn on when the power is turned on; If you choose manual mode, you need to manually press the button to turn the amplifier on.
This switch is often on the back or bottom of the amplifier. In the case of a working mode selector switch, there will usually be several options: stereo, mix, pass-through, and so on.
Before operating, make sure to disconnect the power supply and read the operating manual carefully to avoid any losses caused by incorrect use.

In the case of a working mode selector switch, there will usually be several options: stereo, mix, pass-through, and so on. These options help you choose based on your audio device and listening needs.
Choosing the right working mode can improve your sound quality and sound effects. Important: Before operating, make sure to disconnect the bridge Huai source and read the operating manual carefully to avoid any losses caused by incorrect use.
These two buttons listen to the song, what position to tune to, the left can be adjusted to parallel, and the right can be adjusted to such that the sound quality will be better.
I'm an amplifier, two speakers, and a mobile phone. Connect your phone to play songs. There is no other equipment as shown in the picture above, can you tune it as you said?
OK. If both speakers are connected through the A B speaker port of the power amplifier, then turn the selection switch to the A+B position, and the two speakers will sound at the same time. However, if the two speakers are connected to the amplifier through different ports, then the position of the selector switch needs to be adjusted according to the connection method.
It is recommended to check the manual of the power amplifier or consult the after-sales service personnel to ensure the correct operation.

Anonymous users2024-02-09Summary. Hello dear! The four switches behind the amplifier usually refer to the power switch, the input selection switch, the volume control switch, and the sound control switch.
Power Switch: Control the power on and off status of the power amplifier. Input Selector Switch:
Used to select different input sources, such as aux(auxiliary), cd, ***, Bluetooth, etc. Volume Control Switch: Usually consists of a knob or button that controls the output volume.
Sound Control Switch: Used to adjust the sound effects of the amplifier, such as equalizer, subwoofer gain, etc. These switches are usually labeled with different sound quality modes, such as "rock", "pop", "classical", etc.
Please note that different brands and models of amplifiers may vary slightly in detail, so specific switch functions and logos may vary. If you are not sure about the specific purpose of the switch on the back of the amplifier, please refer to the manual or contact after-sales customer service for help.

Anonymous users2024-02-08Hello dear, a power amplifier switch tube to control two speakers will not be able to be at the same time Royal Silver ****, the sound is not clear and other problems. The reason is that the power amplifier switch can only control the on/off of the current, but cannot adjust the size of the current. When two speakers are connected to the amplifier switch at the same time, the power will be divided equally, resulting in a decrease in the output power of each speaker, which will affect the sound quality.
In addition, if the impedance of the two speakers is different, it will also cause the amplifier switch to not work properly. For example, if the impedance of one speaker is 8 ohms and the other is 4 ohms, then the power amplifier switch will not be able to properly adapt to the impedance difference between the two speakers when controlling the current break, thus affecting the sound effect. Solutions to these problems include:
Use power amplifier switches with higher power supply power, use equipment such as specialized audio splitters to distribute power, choose impedance matched sound systems, and more. In short, when using power amplifier switches to control multiple speakers, pay attention to the power and impedance matching issues to ensure the best sound quality. I'm glad to answer for you, and I hope I can help you.
If my answer is helpful to you, please give a like, look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Best wishes again good health and a good mood!

Anonymous users2024-02-07Summary. Hello dear, the problem of one switch tube and two speakers of the power amplifier is very simple, generally speaking, the output of the power amplifier is connected to two speakers, and the output of the power amplifier is controlled with a switch tube, so as to select the output audio signal from the two speakers. Typically, the easiest way to connect two speakers is to place one speaker on the right and the other on the left, and then use a cable to output the signal from the amplifier output to the input of both speakers.
In addition, it is recommended to use a balanced wire connection to enhance the stability of signal transmission. In addition, it is best to use custom-made, high-performance acoustic cables for better sound.

Lines are a problem.
It is impossible to achieve without using electronic circuits, the circuit diagram upstairs is imaginative, in fact, when stepping on the foot switch, KA1, KA2, KM1, KM2 are constantly interconnected and interlocked, on, power-off oscillation state, and all stop resetting the circuit after releasing the foot switch.
