Long press 1 second:
10 speed adjustment,the top left of the red LED will show the corresponding,1-10 light the more the slower the speed (default 4)
 
Long press 3 seconds:
7 level gain adjustment, the top right of the corresponding LED will show the default value of 4,5/6/7 for the gain magnification 1/2 times, 1/2/3 for the gain reduction 3/2 times)
 
Long press 6 seconds:
1,the left side of the middle of 10 green LED light---L left channel;2,the right side of the middle of 10 green LED light---R right channel,3,about 10 middle green LED light---stereo;Channel Description:Stereo mode,because the left and right channel signal is inconsistent,left and right light bar height will be inconsistent,when set to monaural,left and right light bar shows the height will be consistent,rhythm will be stronger.(Default stereo).Speed and gain Description:According to personal preferences to adjust the drop speed,the general DJ fast song with speed,slow song with slow speed;generally by adjusting the input volume size to control the display amplitude,gain adjustment in the case of inconvenient adjustment of the volume.
 
Instructions:
1.Please connect the cable USB into the computer USB interface,3.5mm headphone head through the audio one Split the two branches into the computer or other equipment headphone output port,another branch connected to the audio equipment;
2.By adjusting the input volume with the gain adjustment will display the amplitude control to the appropriate range,the gain of the special,  In the case of small volume,set it to level 4;
3.The product must use the front signal,the signal amplitude can not exceed 5V, can not directly connected to the amplifier output and the speaker (to be connected with the potentiometer must be attenuated),this will cause damage to the product.
4.Please do not use the cottage phone charger or other ripple is too large, unstable voltage power supply,will cause the end of noise or cause damage to the product.
