Up to 16 Channels, Two-Screen Output

The MV-1620HS is a compact (1RU) multi-viewer that accepts up to 16 channels of mixed HD/SD-SDI or analog composite signals for monitoring on one or two (option) screens. Full-featured yet economical, the unit offers a customizable window layout and displays audio levels, titles, and timers, etc.

Versatile Mixed-Source Environment

Supports mixed signals as required, from HD-SDI, SD-SDI, or analog composite sources. Asynchronous input is also supported. The viewer accepts an array of formats and frame rates including NTSC, PAL, 1080/59.94i, 1080/23.98PsF and 1080/50i.

HD Output of Source Signals

Sources can be displayed on one or two (option) screens, with HDMI and SDI interfaces available for both screens to support HD monitoring.

Layout Manager

Includes a Windows application for managing the layout. Customize the layout on a computer by registering or changing layout patterns, adjusting title display, and configuring other settings as needed. Store up to 16 layout patterns on the viewer. Saved layouts can be applied directly from the front panel control.

Video Streaming

In addition to computer-based layout management, you can also stream video from the viewer over Ethernet. The streaming video can be used for additional local computer display or for remote monitoring.

Front Control Panel

Standard front control panel enables layout and channel switching, local control settings, as well as remote operation.

Audio Level Display

Monitor audio levels of up to 16 channels of HD/SD-SDI embedded audio. For each source signal, use Layout Manager to customize displays for positions, the number of channels shown, and the display groups.

Tally Display/Title Display/Timecode Display

  • Tally: Choose from frame tally or marker tally display.
  • Titles: Identify each source channel with a title. Supports display of alphanumeric characters and symbols (up to 16 letters), which can be displayed within or outside the picture.
  • Timecode: Ancillary Timecode can be displayed on HD/SD-SDI.

Logo Display/Background Display

Register up to eight logos and four background images. Add two logos and one background per output, as required.

Time Display

Correct clock time is ensured by SNTP server sync. Two clocks can be displayed, in analog or digital format. Date display is also available. If not used as a clock display, this feature can be used as a count up/down timer, or remaining time counter.

Audio Monitoring Output

Audio from any channel can be monitored via HD-SDI, HDMI, or analog audio output.

Error Display

  • Video: video signal loss, frozen frames, or incorrect luminance/black levels
  • Audio: audio signal loss, silence, or excessive audio levels
