Simulation Sound Unit Set for 1/18 1/24 1/28 Flat On-Road Rock Crawler Climbing Truck RC Cars Vehicles Models Spare Parts Accessories Description: Item No.:SC0001/SC0002 Item Name:Sound Group Material:Plastic Shell Product Weight:15g Suitable Models:1/28 1/24 1/18 Flat Car Climbing Car Universal Packaging Size:8*12*1cm Style:Diesel Version/Gasoline Version Output Power:1W8 ohm 5V / 0.6 W8 ohm 3V Signal Input:Positive Pulse 0.8 ms to 2.0 ms Sound Quality:22.05 kHz Sampling Frequency Memory:4M, 22.05 kHz Audio is About 20 Seconds Note: The power supply voltage of the sound group is up to 5V, and it must not exceed 5V. If it exceeds 5V, the built-in amplifier and microcontroller will be burned. If the BEC of the electric adjustment is 6V, it is recommended to connect 2 2A in series The rectifier diode removes power from the receiver, and the voltage drop is 1.2-1.4V, which supplies power to the sound group. Control method: After the control is turned on, when the throttle channel moves for the first time, the engine sound will automatically start. If the engine idles for more than 20 seconds, the engine sound will automatically turn off. After the throttle stick moves, the engine sound will start. Neutral point setting: Connect the speaker, ESC, and receiver (the receiver and control should be aligned with the frequency in advance), turn on the power of the remote control, power on the receiver, and then short-circuit (short-circuit) with tweezers or other conductive materials as shown in the figure. At this time, a beep will be emitted, indicating that the midpoint has been recorded, and then the throttle is pushed to the start/idle point. suspend for a while, and there will be another beep, indicating that the start/idle point has been recorded, and then push the throttle to the maximum, and there will be three beeps, and the whole setting is completed. Package included: 1x Diesel Version/Gasoline Version Sound Group
