Dual Link Monitors with Waveform and Vectorscope for Broadcast Video and Audio Analitics

3G Video and Audio Analitics Display

Triple Rate SDI logoMarshall Electronics' DLW Series monitors are the latest addition to the expanding line of IMD (In-Monitor Display) Monitors. The 18.5" V-R185-DLW and the 26" V-R261-DLW IMD monitors include Dual Link with Waveform & Vectorscope. These new models incorporate a 10-bit "no compromise" video path along with one of the industry's first monitors equipped with 3G capability. In Quad-View mode, the monitors break the screen into four quadrants and display Audio Bars, a Waveform Monitor, Vectorscope, and live video simultaneously. Both models have two inputs supporting 3G / HD / SDI and Dual Link. A DVI input supports all HDMI modes and DVI to 170MHz. Additional features include IMD protocol support for TSL, NVISION, Image Video, and MEI (Marshall Electronics) tally control systems, remote firmware update via RS-485, tri-color hard and soft tally, and Safety Marker configurations. Other display features include full CEA-608-B and CEA-708-B Closed Captioning.
