POD9 is a six by one analog video switcher. POD9 may be used in conjunction with an analog audio switcher (POD2), or a digital audio switcher (POD10) for audio follow video applications. When slave mode is engaged, any channel selection on the video switcher will result in the same selection on the audio switcher and vice versa. The video switching on POD9 occurs in the vertical interval. If the currently selected input does not have valid sync, POD9 will switch randomly. POD9 may also be controlled remotely using its RS422 serial interface.
