Today, I will share you something about power amplifier. 1. From the printed fonts: the authentic fonts are well-proportioned and the writing isn't easy to be removed, along with the fake fonts are like the ones written on it. The gentle rubbing the fingernails will create the writing color lighter or even the paint. clear. In the branding of this package press: English letters and numbers are printed on either side of the good screw hole close to the top region of the tube. Along with also the words of different producers or nations are printed in the center of the lower section near the trap, such as SK (three Ken), PHILIPPINES (Philippines), MALAYSIA (Malaysia), etc.. The fakes are not printed, or so the prints over the above two things are nasty and nasty, and these points are not published due to the term position. Of course, a number of the joint ventures have no prints here, however there are no obvious differences between them as well as the original tubes. 3. From the perspective of the packaging and processing technologies of this power amplifier tube: the boundary between the heat sink as well as the package plastic of the real product is crystal clear and the corner is horizontal, and the boundary of this bond of the imitation merchandise is cloudy or even has a gap (the market is the The easy-to-see fakes would be the small Toshiba tubes A1491/C5198, D817/D1047), and the surface has a rough feel just like brushed (this really is the place where the fakes are likely to be filled ). Some models of imported tubes have been subjected to a matte finish on the surface of the fins (like MATALOLA's MJL1302A/MJL3281A), whilst counterfeit and individual joint venture tubes don't have this procedure. From the measurement results: when using the pointer multimeter R × 10k to block the positive and negative resistance between the telephone and electronic poles of this tube, the pointer of the real one is not moving or the angle of the swing is very little, and the imitation The c and electronic pole forward resistance (NPN forwards is Rce, PNP forward is Rec)the swing angle is much larger, that is, the resistance value is smaller (this indicates that the tube has a large penetration current); along with the digital multimeter is used. After measuring the magnification of this tube β, the consistency of the genuine (notably the inlet tube) is quite good, along with the consequences of the imitation is normally poor. 5. Performance when using fake machine: Considering that the pressure resistance of the pipe is usually low, it is easy to cause the pipe to burn when it is turned on; or so the warmth is much more serious than the one. At this moment, the c and electronic pole resistance of the pipe is significantly smaller compared to when it is not installed. More, and the deviation of β is even larger, and there is no such phenomenon in genuine products. If you are searching for the amp company global, I introduce ShuBole.

Because digital amplifiers work entirely differently from conventional analog amplifiers, they overcome some of their inherent shortcomings of analog amplifiers and have some exceptional capabilities. The next introduces the gap between electronic power amplifier and power amplifier that is analog.
The overload capacity of digital power amplifier circuits is much higher than that of analog power amplifiers. When the energy amplifier tube operates in the terminal region during normal operation, once the energy amplifier tube operates in the projection area, harmonic distortion happens and the level of stimulation increases exponentially. The sound quality is rapidly deteriorating. The electronic power is obviously in the saturation zone and the cut-off zone when the power is amplified. Provided that the power amplifier tube isn't damaged, the distortion won't grow rapidly. Since the electronic power amplifier uses a switching amplifier circuit, the performance is extremely high, as much as 75~90 (the analog power amplifier efficiency is only 30~50), and basically does not create heat during operation. Because of this, it does not mimic the static current consumption of this power amplifier. All the energy is almost reserved for the sound output. After adding the analog amplification without negative feedback, it's better"energy" characteristics, and the transient response is great. Feeling is extremely powerful. Difference 2, crossover distortion and mismatch distortion Analog Class B power amplifiers are placed in zero-crossing distortion because of the nonlinearity of the transistor at low currents. Distortion in the positive and negative intersections of the output waveform (the transistor will operate from the cut-off region for small signals, no current will pass, resulting in output Severe distortion). The electronic amplifier just works in the switching state and does not create crossover distortion. The analog power amplifier includes a mismatched distortion of the output waveform as a result of inconsistent push-pull characteristics. Therefore, when designing the push-pull amplifier circuit, the requirements for the power amplifier tube are very rigorous. The digital power amplifier does not have any particular prerequisites for its pairing of the switch tube, and essentially doesn't need to be strictly chosen to be utilized. Difference 3, power amplifier and speaker matching Since the internal resistance of the power amplifier tube in the analog power amplifier is large, once the speakers using different resistance values are matched, the functioning condition of the analog power amplifier circuit is affected by the magnitude of the load (speaker). The internal resistance of the digital power amplifier doesn't exceed 0.2 Ω (the internal resistance of the change tubing plus the inner resistance of this filter), and the resistance value (4~8 Ω) relative to the load (speaker) is completely negligible, so there is no matching problem with the speaker. Difference 4, transient intermodulation distortion Analog power amplifiers use nearly all negative feedback circuits to ensure that their electroacoustic parameters. From the negative feedback circuit, in order to suppress parasitic oscillations, phase compensation circuits are utilized, which will generate transient intermodulation distortion. The digital power amplifier does not use any analog amplification feedback circuit for electricity conversion, thus avoiding transient intermodulation distortion. Difference 5, solid image localization For analog power amplifiers, there is normally a phase difference between the output signal and the input signal, and also the phase distortion is different once the output is different. The digital power amplifier employs digital signal amplification to make the output and the input phase exactly the same, and the phase shift is zero, so the audio image is positioned right. Length 6, update The electronic amplifier can achieve high power by simply replacing the switch amplification module. The high-power switch amplification module has a low price and has wide prospects in the professional area. Difference 7, manufacturing debugging Analog power amplifiers have debugging problems at all levels of work, which isn't conducive to mass production. The digital power amplification component is an electronic circuit, and generally functions normally with no debugging, and is particularly suitable for mass production. During the above introduction, I think that everyone has already understood the difference between digital power amplifier and professional power amplifiers.

February 19th, 20192/19/2019 Which pos machine is easy to use, I can not say it. After all, there are too many pos machines on the market. I can't examine them one by one, but with years of expertise, I can tell you the standard of utilizing pos machine.
If you must make a simple classification of this pos machine, then split him into a fixed pos machine along with also a wireless pos machine. Fixed pos machine is normally a bank pos machine, the program takes a business license, tax number, and physical stores, generally will need to join, so the transaction place is relatively fixed, belonging to one machine, one household and one code pos machine; wireless pos machine largely belongs to the first The three-party pos machine, the application just requires an ID card, the payment location is comparatively free, and the POS machine circulates from the market is a third-party POS machine. Simple to use pos machine regular You can not use all of the pos machines available on the current market, but you can understand the quality of a fantastic pos machine. 1, a Fantastic pos machine Has to Be secure Security is a must-have for a fantastic POS machine. After all, it involves funds. If security is not ensured, then this a POS machine has to be undesirable. What type of pos machine is secure and reliable? A payment license issued by a central bank is the only standard that guarantees and verifies the security of a pos. The way to view and test, the method is as follows: 1 in the official website of the People's Bank of China to make queries; two brush pencil small order, check if the transaction details are UnionPay. 2, a good pos machine must Have the Ability to locate local retailers A POS machine which could find local merchants is the foundation for ensuring that charge cards aren't subject to lender risk management. For instance: POS machine is located at Shanghai, but you have brushed out the merchants in Shandong, the lender backstage, even if it needs to put you a horse is also powerless. As a result, the ability to find a local POS machine is the key to making sure that credit cards are not subject to risk control and derating. 3, a Fantastic pos machine has to swipe the card points Along with, points are a proof of bank spending. In order to seize the credit card market, major banks have introduced the points coverage. The lender's cost of these points accounted for 0.2percent in the 0.45% of their credit card rate. In other words, if you POS machine card with credit points, 0.2% of the 0.6% speed is going to probably be returned to you in the kind of points. At precisely the same time, because the lender provides you things, it means that it acknowledges your credit card spending. If you wanna find some good pos touch screen cash register system, I introduce Nobly.

Many amplifier fans have seen the electric schematics of specialist amplifiers and house amplifiers. If you only examine the electrical schematic, it seems that there is no significant difference between specialist amplifiers and home amplifiers. From the perspective of use, both are used to drive the sound of the speakers, which appears to be the same. How to distinguish between both in life? Let me take you to see whether there's a difference between both.
First: the usage environment differs. The house power amplifier is generally used for home playback, and its attributes are that the sound quality is delicate and soft, the look is more delicate and lovely, the sound pressure level of this noise is not overly high, and also the ability to be received is little. Professional amplifiers are generally used in professional entertainment venues such as dance halls, karaoke halls, Beijing theaters, auditoriums and sports venues. Compared with all the house power amplifier, its sound quality is hard and the look isn't very delicate. Secondly: the substance configuration is different. Professional power amplifiers normally need to work in a high-power state for quite a while, so professional power amplifiers require high power headroom, high reliability, small temperature increase in the output phase, and good circuit stability. To be able to meet such conditions, amplifiers have special factors in design, materials, etc. which are distinct from home amplifiers. Third: From the point of view of function setting, professional electricity machines frequently work with preamplifiers such as mixers, so that they are for the most part pure post-stage amplifiers. The setting of professional amplifier amplifiers is very straightforward, frequently only the power switch and output level adjustment potentiometer (or measure attenuator) on the panel. However, on account of the real needs of professional power amplifiers, it's frequently possible to operate in a two-channel condition, or to become a mono amplifier after"bridging", so the professional power amplifier is frequently provided with a"bridge" switch. These combined amplifiers have many purposes, frequently with audio source selection, monotonic controller, and multiple sound input ports. The above is today's sharing to discuss with you the distinction between specialist amplifiers and house amplifiers. If you wanna find some best dj power amplifier, you can search Shu bole. |
