Relay Volume Board HIFI Volume Controller Remote Volume Panel with Display Balance Volume

Relay volume control finished plate, 0-255 level volume adjustment, control accuracy and left and right balance are very good, can replace the traditional potentiometer.

The on-board relay is the high light signal relay, and the signal loss is very small.The resistance used in the audio part is American DALE smurf resistance, with high balance between the left and right channels, small error and good sound restoration.Board function is concise and practical, abandon redundant function, convenient burn friend refit is used.

The audio part and the control part on the board are completely separated and isolated. The signal is input from the input end of the board and output directly to the output port through the resistance network.The connecting lines on the board are only functional control lines, which do not pass through the audio signal and do not affect the sound quality.

Function introduction:

         1. Use 360-degree coding switch, feel good, 0-255 level volume adjustment. Right-handed volume increases, left-handed volume decreases.

         2. With three or four output control functions, the 6P socket on the left side of the board can output control signals to control multiple input switching boards (which can perfectly match the three or four input switching boards sold by our store). The SET two points on the board socket control three or four-way adjustment. When the SET point is disconnected, the board can control the four-input switch board. When the SET point is connected, the board can control the three-input switch board.

         3, with digital tube display function, the display color is orange, beautiful. The number on the left of the display is the input switching state, and the number of three digits on the right is the volume display, which is very intuitive and the display brightness can be adjusted in 5 levels.

         4, with remote control function, you can remote control volume up, volume down, mute and input. Click the remote control volume button to change the volume step by step. Press and hold the remote control volume button to adjust the volume continuously and quickly.

         5. With remote control learning function, you can learn the remote control of NEC encoding method (Generally, the power amplifier audio remote control is NEC encoding method)

         6. With power-on memory function, the volume and input status of the last power-off will be memorized when the power is turned on.

         7, using accurate software algorithms, switching between levels is very smooth, no pop.

         8. Two volume control boards can be superimposed to form the volume adjustment of the balance circuit.

The operation is as follows:

         1. Rotate the coding switch left and right to adjust the volume. The three digital tubes on the right side of the display will display the volume value accordingly.

         2. Click the coding switch to switch the input status of the external input board, and the corresponding input status of a digital tube on the left of the display.

         3. Press and hold the coding switch. When the volume number flashes, let go, the output will be muted, and the volume display will always flash. Repeat the operation once or rotate the coding switch left or right or press the remote control volume button to cancel the mute and restore the volume.

         4. Press and hold the coding switch, let go when the volume number is displayed as L (brightness LIGHT code), and then turn the coding switch to adjust the display brightness. The brightness can be adjusted from 1-5 levels.

         5. Press and hold the code switch. When the display is 8 888, let go. At this time, it is the learning state of the remote control. At this time, rotate the code switch to display IN (input), VoL + (volume plus), and VoL- (volume minus). When you press the corresponding key of the remote control to be learned, you can learn the keys of the remote control. After the learning is completed, click the coding switch to save and exit. In the learning state, if you turn the coding switch to CLEA (CLEAR clear) on the display, click the coding switch to clear the learned data and exit.

         6. Press and hold the coding switch, and let go when the volume number is displayed as i r, you can switch between i r1 or i r2 to turn off the remote control function.

 
       The board is powered by AC 12V, and there are voltage regulator chips on the board to stabilize each working point.

 Default shipping list: volume control board * 1 + display board (with connection cable) * 1 + coding switch board (with connection cable) * 1 + remote control * 1

Can also be composed of two balance volume adjustment, the balance scheme is: volume control main board *2 display board *1 coding switch board *1 remote control *1, with good wiring, connected to the power supply, input and output can be used.
