Scalable inputs and outputs

The number of inputs and outputs is scalable by combining two, three, four or six modules and a rear panel option that integrates all inputs to all outputs. Unlike cascading, the method of expansion used in the KMX-3921 does not add delay or latency to sources coming from different modules. 4K UHD output capability is available on the KMX-3921 in combinations of two or more cards.

Choice of multiviewer output connectivity options

Rear panels are available with one or two SFP slots. Each SFP slot can be equipped with one of the following SFP output options: SDI coaxial for broadcast monitors, HDMI for displays installed close to the multiviewer and fiber for extending the distance to the display. The HDMI output SFP option is designed with a latching mechanism to ensure the connection is solid in high vibration mobile environments such as outside broadcast trucks.

All the features you need for live production

Providing fast, easy and simplified workflows, the KMX-3921 is ready to go with all the features required for production control rooms and outside broadcast trucks. This includes timecode displays, built-in timers, safe area markers, audio meters and tallies from the production switcher. The KMX-3921 also offers multiple levels of UMDs showing both static or dynamic information obtained from the control system, the production switcher or the tally management system. The fast processing time of one field makes it perfect for live production monitoring.

High Dynamic Range (HDR) processing for accurate monitoring experience

Introducing high dynamic range (HDR) and wide color gamut (WGC) into a live production workflow adds a challenge for accurately viewing these sources on a multiviewer. Without an HDR capable multiviewer, the image will appear saturated, details are washed out, and colors are incorrectly reproduced. Adding HDR/WCG processing on the multiviewer provides the ability to correct this and provide a more accurate image, more HDR-like, on regular SDR displays. The KMX-3921 provides HDR and WCG processing for HLG, PQ and S-Log3 HDR format, and BT.2020 WCG. Each input is individually configurable which allows to mix and match SDR and HDR sources, as well as different format of HDR, on the same display.

Ready for playout master control and transmission

The KMX-3921 provides all of the advanced probing and metadata extraction for ensuring the quality of your on-air transmission, including specialized features like Dolby-E monitoring, zone-based black and freeze detection.

Optimized for Production Monitoring

With its unmatched space and energy efficiency, KMX-3921 is especially well suited to production monitoring in trucks. It also offers the picture quality and display flexibility demanded by the most critical operators. Its lightning fast processing removes the need for complex audio delay compensation, while satisfying the most discerning of directors.
The multiviewer system integrates tightly with the NVISION 8500 Hybrid routers with integrated audio processing, as well as Densité signal processing cards, and third-party production switchers. Control of a highly integrated system is simplified with the RCP-200 panel, which can operate the router and multiviewer, as well as signal processing and distribution cards.

Router Integration for Large Systems

The KMX-3921 offers seamless integration with the NVISION router family, and third-party routers, to allow expansion up to 1,152 video inputs and 256 multiviewer outputs. By using the “Kaleido Cluster Feature,” multiple multiviewers can behave like a single virtual system from an operator’s perspective, with full layout flexibility.

For example, two NVISION 8576 routers are integrated with 128 KMX-3921 multiviewer cards, housed in 6 Densité 3+ frames (24 RU total), to provide up to 256 multiviewer outputs. This system spans three independent control rooms, controlled by three operators.
