Introduction
The CMN-91 compact video and audio monitoring unit is the most advanced, versatile, and intuitive
monitoring instrument available today. The CMN-91 is available for HD-SDI/SD-SDI (which can be
upgraded to 3 Gb/s capability in two SDI inputs). With 100% digital signal processing technology;
integral, high-resolution, XGA TFT color LCD display; the CMN-91 provides an accurate and stable user
customizable display of waveform, vector, gamut, audio, picture, relative timing, and alarm status
functions in full-screen views. In addition, the CMN-91 provides overlay display capabilities for vector,
waveform, and picture-in-picture (PIP) functions. Quick setup and parameter changes are possible with
direct access to display functions and screen location, 99 presets, context-sensitive shortcut menus, and
an intuitive navigation system.
The CMN-91 features extensive audio and video alarm capabilities, including peak level reporting. All
real-time signal alarms have user adjustable limits, time stamps from LTC or DVITC and an internal clock.
Remote interfaces include 10/100Base-T Ethernet and plug and-play USB port (supporting storage and
recall of presets and frame-capture transfer). The CMN-91 instruments are digital instruments with all-
digital architecture; therefore, no periodic calibration is required. When a CMN-91 unit is equipped with
the optional battery mount, a user-supplied lithium ion battery can be used to maintain power in the
field.
The CMN-91 seamlessly integrates into any broadcast, post-production, camera maintenance, satellite
or cable facility, and is the ultimate choice for quality control, troubleshooting, or compliance checking
applications.
