笔者最近借用了一台NV-M8000EN摄录一体机,经使用,该机摄录的画面和伴音效果良好(AV输出方式),该机附带一台AC适配器(含电源、充电器和射频调制器),型号为VW-AM7,经与普通PAL-D制式彩电配接,放像试看,发现图像良好,无伴音,因该调制器为EN制式,伴音载频为5.5MHz,与我国的6.5MHz相差1MHz,需将该调制器伴音载频调制到6.5MHz上。首先,打开AC适配器,找到调制器小盒,找出调制集成电路 The author recently borrowed a NV-M8000EN camcorder, the use of the aircraft recorded good sound and sound (AV output mode), the aircraft comes with an AC adapter (including power supply, charger and RF modulator ), Model VW-AM7, with ordinary PAL-D standard TV connection, put the picture to see and found the image is good, no sound, because the modulator is EN standard, sound carrier frequency is 5.5MHz, and China’s 6.5MHz A difference of 1MHz, the modulator sound carrier frequency to be modulated to 6.5MHz. First, turn on the AC adapter, find the modulator box, and find out the modulation IC
