Motherboard size: 12CM * 4.9CM
Motor motor drive voltage: 4VAudio selection signal number: 4 wayPower supply control Output voltage: 4.5V (direct drive relay)Remote control instructions:POWER power switchINPUT input selectionVOL volume fineBRIGHT volume coarse adjustmentVolume control method:*Y*ou can directly use the hand screw potentiometer to play manual volume control*Press VOL + / VOL- to adjust the volume. At this time, the potentiometer is rotated at 4 degrees each time it is pressed.*With the remote control by BRIGHT + / BRIGHT- is the volume rough at this time the potentiometer to each time by a key 15 degrees angle rotation is a rough adjustment of volume*Two-speed with the use of coarse adjustment roughly the volume value, and then fine-tuning precision positioning volume value. Both fast and fine.Package:1x Motor Volume board1x Audio switch board1x Remote control1x Cable
