Operating instructions：

1.AC/DC12-16V power supply, must distinguish between AC and DC inputs.L, G, R: This is to drive the dual-channel input terminals of the board, can be connected to a cell phone, computer sound card, preamplifier and other audio source equipment audio (signal for the signal that can be heard by the headphones), amplifier outputs to get the letter, wiring L, G, R corresponds to the sound source equipment connected to the left, ground, right channel, if the input is a cell phone, computer sound card, If the input is a cell phone, computer sound card, preamplifier and other audio sources, please put the dipswitch 1 and 3 to the “ON” end, 1.AC/DC12-16V power supply, to distinguish between AC and DC inputs.


2.L, G, R: This is to drive the dual-channel input terminals of the board, can be connected to a cell phone, computer sound card, preamplifier and other audio source equipment audio (signal for the headset can be heard), the amplifier output to get the letter, wiring L, G, R, respectively, corresponding to the audio source equipment connected to the left, ground, right channel, if the input is a cell phone, computer sound card, preamplifier and other audio sources, the dip switches 1 and 3 to the “ON” end. If the input is a cell phone, computer sound card, preamplifier and other audio sources, please play the dip switch 1 and 3 to the “ON” side, if the input is the amplifier output to get the signal, please play the dip switch 2 and 4 to the “ON” side, the signal will be compressed 11 times. Note: You can not pull the code switch at the same time to the 1 to 4 dip switches are played to the “ON” end.


3. Adjustable potentiometer “100R-V” for adjusting the backlight of vu meter.


4. Adjustable potentiometer “50k-1” and “50k-2” to control the amplitude of the pointer jump of VU table 1 and VU table 2 respectively.
