How do you know audio encoder is broken?

Encoder control volume and timbre of the sound, the sound but we sometimes can appear some fault, then the fault is caused by a malfunctioning encoder damaged? Take a look at the following fault, bothering you? A lot of people a voice on both sides of the power amplifier is not the same size, about the volume of the main speakers should be balanced, do not agree if it shows that the volume encoder. Bad there are a lot of cause of encoder, possible deformation inside the brush of the rotary encoder, it is possible that the dirt on the surface of the rotating and deformation, the general is the use of dual stereo encoder is the volume of the two linkage tuner control the volume of the two channels at the same time, one of the vocal tract after wear and another channel of contact resistance is different, so the volume have changed, if you make noise when adjusting the volume, that is caused by carbon granule grinding down, if there is one channel volume is small and big noise may be encoder and move on the ground without contact with the sliding vane, is no input signal, what you hear is from another channel crosstalk signals come in. So this kind of situation can only clean or replace encoder. Shanghai electronic 26 years specializing in the production of encoder, focus, professional! Specializing in the production of a variety of audio encoder and rotary encoder, straight sliding encoder, switch, encoders, take the motor encoder, encoder models complete, safe and reliable quality, find the encoder manufacturers are looking for electronics.
