Description
The GC-AV04 is a sophisticated PAL NTSC System AV Signal to RF Modulator, designed to provide high-quality video output for various applications. With its MCU-controlled PLL technology, this device ensures exceptional accuracy and stability of both visual carrier and audio subcarrier signals. Ideal for converting AV signals to RF format, the GC-AV04 features selectable audio subcarrier frequencies of 5.5MHz, 6.0MHz, and 6.5MHz to meet diverse user needs.
Equipped with an RF loop input and an automatic storage feature that activates during power outages, the modulator offers convenience and reliability in operation. An LED channel number display makes it easy to monitor settings, while double sideband modulation allows for non-adjacent channel usage, enhancing flexibility in signal transmission.
