Fast forward fast rewind function need to implement via remote control. (Without Remote control , need to buy This Board without Bluetooth Function only support Bluetooth sticker , Bluetooth sticker not including . ) Strong power, 3 watts stereo output, loud and clear, (recommended to use 3 w - 10 w, diameter of 3 inches of the horn ). Panelfunction instruction: 1 IR Reciver ( remote control need to buy another ) 2 "SD":SD/MMC SLOT , can automatically play when plug in SD/MMC Card (Need SD Adpater if use TF Card ) 3 "USB" :U Disk Plug ,can automatically play when plug in 4 "PREV/VOL-" :Long press for volume -; On the USB/SD state short press for Prev 5 "PLAY/PAUSE" :On the USB/SD state short press for PLAY/PAUSE 6 "NEXT/VOL+":Long press for volume +; On the USB/SD state short press for Next 7 Working indicator : Light after connect power , Flashing when working Wiring instructions: (please use 2pcs 4 o 3-5 w Full frequency speaker) 1, Red seat "GND" for "-5v " "5v" for "+5v " 2, white seat "L- " for "- left speaker ", " L+" for " + left speaker " 3, white seat "R -" for "- right speaker " , "R+" for "+ Right speaker " Warm Tips: Decoding board power supply requirements: full-wave rectifier power supply, not less than 2200 uf capacitor filter. Output voltage is not higher than 5 v direct current, the current 800 ma - 1 a, if the current power supply shortage: can produce repeated switch machine, pause and similar phenomena. Please do not use the charger to power a decoding board. Especially easy to damage the decoder board. Speaker wiring : Amplifier output is BTL output , no common ground,The "+" and "-" of left and right channels couldn\`t be connected together which can cause damage to the power amplifier chip. Also can not put the speaker output from other amplifiers, can also damage to power amplifier chip -->
