Product Description
Blustream CMX42CS 4x2 4K HDMI 2.0 Matrix
The Blustream CMX42CS 4x2 4K HDMI 2.0 Matrix is engineered for high-performance AV signal routing in demanding custom installation environments. Designed to distribute up to four HDMI source devices to two independent HDMI outputs, it combines premium 4K video support with advanced integration capabilities.
Flexible 4x2 HDMI Routing for Custom AV Systems
The CMX42CS features 4 HDMI inputs that can be independently routed to 2 HDMI outputs, making it an ideal solution for residential AV systems, boardrooms, classrooms, and multi-zone commercial environments requiring reliable 4K video distribution and system control.
- 4 x HDMI inputs
- 2 x HDMI outputs
- Independent routing to each display
- HDCP 2.2 support
Full 4K UHD 60Hz 4:4:4 and HDR Compatibility
Supporting full HDMI 2.0 with 18Gbps bandwidth, the CMX42CS handles all video resolutions up to 4K UHD at 60Hz 4:4:4 and supports HDR. This ensures full compatibility with the latest UHD and HDR content for premium video performance.
- Supports HDMI 2.0 18Gbps specification including HDR
- Supports up to 4K UHD 60Hz 4:4:4
- Supports all industry standard video resolutions including VGA-WUXGA and 480i-4K
Output Down-Conversion for Mixed Resolution Displays
Video down-conversion on the outputs allows a display that only supports lower video resolutions, including 4K 60Hz 4:2:0 or 1080p, to receive 4K 60Hz 4:4:4 video content while the remaining video output still shows maximum original 4K UHD resolution. This makes the matrix especially useful in installations using displays with different resolution capabilities.
- Supports mixed display resolutions on the two outputs
- Allows lower-resolution displays to receive compatible video output
- Maintains maximum original 4K UHD resolution on the remaining output
Advanced Audio Breakout and Control Integration
For system integration, the CMX42CS supports bitstream passthrough of multichannel surround sound including object-based audio formats in line with HDMI specifications. It also provides HDMI audio breakout to associated output analogue L/R audio and coaxial digital outputs concurrently, with control available via front panel, TCP/IP, IR, and RS-232.
