Product details:
MV02 is a high quality and affordable entry level remote control volume control and input signal selection kit.
This kit uses the CPU to control the selection of input signals and control the motor to rotate the potentiometer to complete the volume control.
Using the original ALPS metal shell sealed potentiometer, high reliability, and sound quality performance.
MV02 adopts dual potentiometer, support 4 groups of dual channel input.
With special remote control, remote control or manual operation, the function is very complete.
This kit is used to replace the traditional mechanical signal selection and the VR effect is very good, and the construction is simple. The most important only 180 yuan can upgrade complete remote control system, the price is even lower than the price of a few potentiometers, the high cost performance really belongs to invincible.
MV02 has automatic reset function, reset to low volume state every time the machine is opened, in case of damage to the speaker by mistake operation. You can also cancel the reset function. Install two 10R resistors, R17 and R18, which were not installed on the board before, to cancel the power-on reset action.

MV02 port instructions
CN8 terminal: input AC 9-12V (500mA) working voltage
CN4 terminal: A \ B \ C connected to 360 degree pulse switch, manually select the input signal
CN5 terminal: L+, L1-L5, a total of six pins, can be connected to 5 LED lights, indicating the input signal channel, L+ is connected to 5 LED anodes, LED cathode is connected to L1-L5 pins respectively
CN3 terminal: 1, G, +5V connected to the remote control receiver. 1 is connected to the first pin of the receiving head, G (ground) is connected to the middle pin of the receiving head, and 5V is connected to the third pin of the receiving head. (Receiving head and feet down, 1, 2, 3 feet from left to right)
CN1 terminal: six-pin, connected with the matching signal switching board BN1
BN2 terminal: connected with matching signal switching board CN2 to realize audio transmission. If signal switching is not required, audio signal can be directly input into BN2
BN7 terminal: signal output terminal
BN9 end: equal loudness switch, generally recommended not.
