(aka DMON-10S)


12 channel multiviewer with SDI and HDMI outputs for 3G/HD/SD

The DMON-12S from Decimator Design is a low cost, miniature 12 to 1 Multiviewer. The 12 SDI inputs are independent of each other, meaning you can monitor a mix of 3G/HD/SD feeds.  Select from preset layouts or customise your own, depending on the number of feeds you wish to monitor.  The Decimator DMON-12S multiviewer allows you to:

  • Monitor between 1 and 12 independent 3G/HD/SD-SDI feeds
  • Select your output format over SDI and/or HDMI
  • Fully customisable layouts with ability to save & load
  • 16 character customisable UMD overlay per window
  • 16 channel customisable Audio Metering overlay per window
  • Safe Action, Safe Title and Centre Cross overlays
  • Monitor variable aspect ratios per quadrant
  • Auto Detect & display any format of any frame rate simultaneously
  • Select any of the 12 inputs for pass-through
  • Dynamic UMDs via TSL protocol on RS422/485
  • Control from a distance via USB on a Mac/PC app or via 32-Pin GPI
  • Control on-unit using the buttons and LCD screen
  • Toggle one feed to fullscreen

This product replaces the DMON-10S - all customers who pre-ordered the 10s will receive a DMON-12S (same price!).

DMON-12S comes with a Locking DC Power Supply, USB Cable, HDMI Cable & Mounting Bracket.  Warranty for all Decimator Design products is 3 years.
