CMN-41
Multiformat Onscreen Monitor
Meet the new Videotek® Compact Monitor Series — including the CMN-41 family of multiformat onscreen monitors. The smallest solution on the market for efficient video and audio signal monitoring, the CMN-41 tests signal quality across all DTV formats up to 3 Gb/s. It's available in three versions: the CMN-41 with DVI-D output, the CMN-41L with a blank front panel and DVI-D output, and the CMN-MV with 720p/59.94 SDI output. Each model possesses two SDI inputs and provides selectable waveform, vector, gamut, timing and picture full-screen display.
With Videotek compact monitors you can meter all 16 channels of embedded audio or one AES input. You can also view the waveform of the composite or tri-level external reference to verify signal integrity and customize the MLT display with independent size and position of waveform, vector and picture.
Features

- Waveform display of external reference or LTC input
- Overlay display with independent size and position of waveform, vector and picture
- DVI-D external display output (CMN-41 and CMN-41L)
- 720p/59.94 SDI display output (CMN-MV)
- 99 presets
- Standard four-pin XLR DC power input (AC adapter supplied)
- Convection cooled, silent operation (no fan)
- Front-panel headphone jack (except CMN-41L)
- Front-panel USB port for save/recall of presets, screen captures and SDI captures (except CMN-41L)
- Dual rackmount option available
- Desktop case with tilt bail option available
Product Details
All three CMN-41 units are available with SD, HD/SD or 3G/HD/SD inputs. The SD and HD/SD models are fully upgradeable to 3G/HD/SD.
A standard 11-17 VDC power input provides flexible powering for both fixed installations and field operation. Low power consumption allows the use of convection cooling for energy-saving, silent operation.
The CMN-41 can be mounted in either a dual rackmount tray or a standalone desktop case. Each package has a compact half-rack footprint less than seven inches deep — a short mounting depth that integrates easily with today’s LCD monitors.
