BP machine type BA1404 FM stereo transmitter
(Product code: B04J)
Product function: convert the input stereo audio signal or microphone signal into FM radio wave and send it out for FM radio reception, realize the function of wireless transmission of stereo audio signal and microphone signal, pilot frequency modulation stereo transmission.
The transmitter is only the size of a BP machine, with a waist buckle,Dimensions without antenna are 8X5.5X1.5cm, Adopt advanced pilot frequency modulation stereo transmission technology, internal circuit adopts BA1404 integrated circuit, can be connected with external stereo sound source, and can be connected with matching lavalier microphone. The stereo sound source jack can double as an external lavalier microphone jack. Audio transmission line or lavalier microphone line also serves as a transmitting antenna,The working frequency is continuously adjustable within 87-110MHz, the transmitting distance is within 50 meters, and it is powered by 2 AAA batteries. Supporting lavalier microphone and audio transmission line. If you don’t need an audio transmission line, you can reduce it by 2 yuan, and if you don’t need a lavalier microphone, you can reduce it by 6 yuan.
The working current of the transmitter is about 35mA, and the capacity of each AAA battery is 500mAh (milliampere hour) for ordinary high-quality alkaline batteries. The continuous working time of two batteries is about:(500X2/35)X0.6=17 hours. The above is an estimate, for reference only. Actually, there may be a large discrepancy due to the different types of batteries used.
The above transmission distance is for reference only, notBasic indicators of the transmitter. The transmission distance is affected by many factors, such as what antenna is used for transmission, the height of the transmitting antenna, the surrounding obstacles, the sensitivity of the receiver, the weather, etc., which will cause great discrepancies, and the actual use and working environment of each customer Different, it is recommended to measure. If you are not satisfied after receiving the goods, please do not confirm the receipt of the goods, please negotiate and solve them in a friendly manner. Thank you for your cooperation!
