Use power amplifier audio encoder to replace the note

Power amplifier audio is suitable for what kind of encoder? The encoder with resistance and the relationship between the rotation Angle to points can be divided into index model, logarithm model and linear type 3 kinds. Index is characterized by an encoder with the first resistance rate is small, the late. Logarithmic type encoder, on the other hand. Linear encoder is resistance rate and rotation Angle is geometric. The human ear has a feature, in a small volume, a slight change of the size of the volume, the ear can awareness, but when the volume, even if the volume changes significantly, the ear is checked out. Is ear is sensitive to the size of the volume in small volume, when the volume is very slow. Based on this principle, the volume of the audio encoder, the most appropriate chooses index type. Like this, when tuning amount, no matter in which the volume position, regulators can feel the volume change rate and rotation Angle is geometric, if use other type, regulators would feel the volume change and adjust the Angle range than, nothing more, not to have any effect the electrical performance of the machine. Is the total value of the impact of electrical properties. However, there is a kind of special, the volume of the encoder with the four feet of intermediate tap encoder, because tap to control the loudness, if use the wrong type, such as ring circuit parameters will be affected, in this respect, the sound quality will have certain influence. Power amplifier audio encoder replacement notice if it is three feet encoder, three types are interchangeable, especially linear model can say 'universal' more, even with the wrong also won't produce adverse effect, just adjust the feeling 'was not used to. If it is four feet encoder, practice can still swap, because the resulting the bad influence of peer ring is not big. Won't produce 'largest volume decreases. Power amplifier audio coder using note 1. In operation on the regulation of power amplifier audio encoder don't too much, too much will cause the encoder on the volume of pores caused by closed tightly. 2. In the process of the use of the power amplifier audio, volume adjustment, be careful not to wet to lest cause electric shock accidents, on the one hand, can easily lead to both if the interior of the encoder with the invasion of the droplets, is caused the problem such as short circuit fault causes encoder. 3. Installation of power amplifier audio encoder, to make sure whether the encoder installation is firm, or in the use of encoder is causes some problem such as poor contact. 4. About the wiring of power amplifier audio encoder, there cannot be a wrong note, or power, once the line between the current is not compatible, thus easy to cause the damaged encoder. Shanghai electronic products is 27 years old, encoder manufacturers, specializing in the production of various types of encoder. The research and development production experience accumulated for many years, factory has multiple parts department, can provide customers with a axis type, long axial length and working parts, shaft sleeve type, long sleeves, the resistance and its linear error values, professional custom, looking for looking for electronic encoder manufacturers.
