Support folder selection playback – convenient for different music categories to choose to play SD card / U disk to put music into different folders, DJ music / background music / children's songs; in the playback mode, the remote control long press the up or down button, The panel long presses the pause play button, you can select the folder to play (at the same time there will be F001, F002, ..)
4. Loop mode: Press the “arrow or “RPT” symbol key in the playback state: random (RAN) / single loop (ONE) / folder loop (FOL) / full loop (ALL); if it is in the current file Pressing (FOL) under the folder will only play the whole song in this folder.
5. Support USB/card/Bluetooth/FM/AUX switching. Conversion prompt and caller number (voice English)
6. Support MP3/WMA/WAV format music. MP3 song 32-320kbps, lossless APE/FLAC/WMA/WAV is the normal second sound channel below 1411kbps
7. Support USB / card switching, previous song, next song, volume adjustment, EQ, play / pause, stop, single repeat, mute, shutdown, direct selection of songs.
8. Support Bluetoot last song, next song, volume adjustment, play / pause, mute.
9. Support power-off memory function: The song and volume played before the memory is powered off can be memorized to the current point. Breakpoint memory (when the USB flash drive or SD/TF card is pulled out in the playback state, it will be broken after about 3 seconds. When it is powered on again, it will play the breakpoint. If the power is removed, the USB flash drive or the card can only remember the current Qu, can't remember when it is)

1: Working voltage 12V: DC 7V-12V, 5V: 3.7V-5V (mini USB MICR0 line head plug) current 800MA-1A. If the current is not enough, there will be a jump or remote control failure or you can't read the Bluetooth abnormality (if you have this problem, please check your power supply); the voltage can't be higher than the highest voltage range required by the product, otherwise the main chip and related components will be damaged.
2: The module power ground and signal ground are separated, and there is a separate resistor to facilitate the selection of different power amplifiers (see the Rohm 0-ohm resistor on the board). The current shipment has been connected with 0 ohms. Individual amplifiers have noise. It is recommended to use a power supply to power the decoder board separately. If the power supply is the same as the power supply, please connect the audio output ground of the decoder board to the power ground (“AGND” and “GND” R32. 0 ohm resistor) must be opened here to be wired (operating in the case of power off);

Two: car modification notice
1) Power supply: Do not directly connect the battery to the power supply, cigarette lighter, and car lock. There are precedents for unstable voltage in these three places, and there are some cars that have interference. Pay attention! ! Please connect the CD or the power supply after the card is rectified and regulated (usually 8-10V). The pillars on the car with the 12V electric cable behind the CD iron shell are still not regulated and rectified; remember!!; if you can't or will not find the corresponding power supply, you can contact us.
2) If you are looking for the audio signal line in the CD player when you are remodeling on the car, if you are not sure which line is the audio input, it is recommended that the left and right audio output lines of the decoder board be connected in series with an electrolytic capacitor within 10UF. Protect the decoded audio output module.
Three: home modification notice
A: From the original power amplifier, you should pay attention to the DC power supply after the power amplifier is rectified; do not connect directly to the power supply at the transformer or before rectification, the power at the transformer and before rectification is AC power, and the router is also AC power. Can not directly supply power to the decoder board, which will burn out the product)
B: The power supply needs full-wave rectification, and the filter has a capacitance of more than 1000 UF to supply power to the decoder board. If the poorly filtered power supply has a direct impact on the sound quality and decoding quality
Regarding the problem of car audio interference (a common type of scene), depending on the condition of the car, it can be handled as follows
C: If it is not the power taken on the CD circuit, a DC-DC isolated power supply can be added.
D: The audio output is connected to a 1:1 isolated audio transformer (note the audio dedicated transformer).
E: Connect a BA3121 circuit (noise reduction circuit)
Four: car and home modified audio wiring:
A. Audio cable is connected to the circuit board: the audio output of the decoder board “R-OUT/GND/L-OUT” is connected to the audio input “R-IN/GND/L-IN” of your amplifier; then you The sound source on the original power amplifier should be disconnected. The audio output of the undecodeable board and the original power amplifier are connected to the power amplifier in parallel at the same time, so that the power supply will burn out the chip or other components; if it needs to connect other audio sources, it must be The audio signal is connected to the audio input of the decoder board, remember! !
B. Connect with 3.5 audio cable: The audio output “R-OUT/GND/L-OUT” on the decoder board is directly connected with “3.5 audio cable” and then plugged into your amplifier or the “AUX” hole of the car. It is the simplest and most convenient wiring method. It is recommended to use this connection method.
