（One）Introduction of traditional carbon film potentiometer: Carbon film potentiometer is the most widely used electronic component in electronic products. Its resistor body is made of ground carbon black, quartz, graphite and other raw materials, which is formed by coating on the surface of the potentiometer substrate. of. Its production process is relatively simple, and the raw materials are relatively civilian, so carbon film potentiometers on the market have been favored by the market for decades. There are several types of carbon film potentiometers: large, small, and micro. Some of them form a switch potentiometer with a switch. It is made by coating a layer of carbon film on a horseshoe-shaped paper rubber sheet. The relationship between the resistance change and the position of the intermediate contact is linear, logarithmic and exponential.

（two）The shortcomings of traditional carbon film potentiometers are introduced: Traditional carbon film potentiometers are non-linear, with relatively weak moisture resistance, relatively large current noise, relatively poor resistance stability, and the internal carbon film coating is easy to wear, resulting in easy oxidation of the contact surface. Therefore, annoying noise will be generated during rotation.

（three）Features of Yuanyun new potentiometer: The new potentiometer avoids the shortcomings of traditional potentiometers and has advantages that traditional potentiometers do not have. When the potentiometer adjusts the volume, there is no problem such as popping, skipping, crosstalk and noise generated during rotation. The weak signal is completed by the resistance network and relay, and is completely isolated from the digital control part and the power supply, so no noise is generated.

Our senior engineers have designed very perfect resistance network parameters, so that our potentiometer has a superior attenuation curve, the sound performance is crystal clear, the sound field is natural, the resolution is high, and the balance is superior. This is the best architecture in the current HI-END world.

Through the signal given by the single-chip microcomputer, the relay is controlled to switch the resistance network, so that the electricThe resistance value of the resistance network is changed to complete the signal gain, 0-99 level volume adjustment, no popping, pure resistance loop, high fidelity, wide and loose sound field, bringing you an unimaginable auditory feast!

product description:

1: The potentiometer shell adopts an integral CNC-processed shell, and adopts a moderate hand feeling and a good rotary damping encoder as the integral operating part of the potentiometer. It has a long service life and does not affect the sound quality.

2: Adopt the form of encoder and MCU, pure resistance circuit, exponential curve, adjust the sense of hearing smoothly.

3: With Dutch VISHAY（BC）  Round crystal one-thousandth high-precision chip resistors have high reliability and strong vibration resistance. The defect rate of solder joints is very low. Excellent high frequency characteristics. Reduced electromagnetic and radio frequency interference has a good guarantee for sound quality.

4: The potentiometer has a variety of volume impedances for selection, 5K-10K-20K-50K-100K, suitable for various machines.

5: Adopt Omron or Japan NEC audio gold contact relay, which has a long life. The gold-plated contacts mainly improve the contact resistance of the contacts, reduce the loss and have a long service life, and ensure good contact.

6: The original rhyme potentiometer can be replaced very simply without the need to make a lot of effort to modify the machine by using the source rhyme potentiometer.（Note that this potentiometer system needs a set of DC5V voltage）!

7: With remote control switch, remote control volume control function, remote control signal switching function, mute function, display function, the above functions can be freely matched.

Remarks: Due to the built-in voltage regulator of this potentiometer, the case may have a little temperature within the normal range. The internal control power system reserves a grounding point. The ground wire does not participate in any sound source loop by default when it leaves the factory. The user can connect this ground wire reasonably according to the actual conditions of use.

Warm sound prompt:

Note that not all devices will have this kind of situation. If a similar situation occurs, it is not a problem with the potentiometer itself, but a problem with the matching of the two. Traditional potentiometers control the voltage level of the input signal, and the loss of weak signals is very large. The shunt type is to control the current of the input signal. Very low loss.

There are two solutions: 1. Change the gain to a smaller value. The general pre-stage gain is 10 times amplification. You only need to change the gain to a smaller value.（Can be changed about 5 times）. 2The potentiometer input string is only 5K-100K. For detailed values, please contact our technicians or contact our customers.

To ensure the stable power supply of the MCU, the external voltage should not exceed DC12V.
