The RM Series is a full-featured, low-cost range of in-rack 3G/HD/SD-SDI and CVBS video monitors ideal for the many feeds in mobile trucks, news and transmission control rooms, duplication, and post production applications. These tilting monitors come standard with in-monitor level metering, selectable video waveform and vectorscope, safe and title markers, labeling, tally, timecode, video format, and built-in color bars, as well as familiar CRT-style picture controls and an intuitive on-screen configuration menu. Input signals are automatically detected and embedded audio in a 3G/HD/SD-SDI bitstream may be selected for visual monitoring on-screen via bar graph style level meters. A headphone jack provides audible stereo monitoring of selected left and right channels. Each of the four high-resolution LCD screens display high-definition or standard-definition video at either 16:9 or 4:3 aspect ratio. Parameters are selected and adjusted using an on-screen display menu.
