The DMON-12S is a 12-channel multiviewer that also works as a 12-to-1 multiplexer, taking 12 independent 3G/HD/SD-SDI inputs and either displaying them combined on one screen or switching a single selected input through to the output. It supports up to 1080p@60/59.94/50Hz on both input and output, with two SDI outputs and one HDMI output. Front-panel LCD menu access means every setting is reachable without a computer or DIP switches, suiting both on-location and studio use. Each multiview window carries its own 16-channel audio metering overlay, individually enabled with custom positioning and sizing, and the unit can display multiple simultaneous formats and frame rates across its inputs, with a choice of preset or custom layouts. RS-422 and RS-485 support lets you select tally display and control UMD position and size, with up to 32 GPI available.
