Kramer MC3−2Ri Key Features
- High Performance Standard Extender: Professional HDBaseT extender enabling long-reach signals over twisted-pair infrastructure with visually lossless performance for 4K@60 (4:4:4) and HDR signals, nearly doubling the extension reach compared to uncompressed signals.
- Future-proof, Standard Extender: Backwards compatible with other standard HDBaseT extenders, automatically adapting to connection capabilities and supporting both compressed and uncompressed HDBaseT signals.
- Intelligent Compression Handling: Automatically detects extenders without compression, disabling compression to ensure compliance with connected devices.
- HDMI™ Signal Distribution: Compliant with HDCP 2.2 and supporting a range of video formats and audio channels as specified by HDMI 2.0 standard, ensuring high-quality content delivery.
- Multi-channel Audio Transmission: Supports up to 32 channels of digital stereo uncompressed audio for delivering studio-grade surround sound.
- Ethernet Extension: Facilitates up to 100Mbps Ethernet connectivity for LAN communication and device control over the same cable as video and audio.
- Intelligent Forward Audio Routing: Allows per-port user selection for analog audio port signal conversion to digital, enabling flexibility in audio source management and external speaker use.
- Intelligent ARC Routing: Routes output-returned ARC signals to analog audio ports for enhanced audio playback and volume control using IR remote systems.
- Bidirectional RS–232 Extension: Enables serial interface data transmission for comprehensive device control in both directions.
- Bidirectional Infrared Extension: Supports remote control of devices located remotely through IR interface data flow.
- Easy Installation: Supports PoE, allowing power and signals to be transmitted through a single cable to remote devices, simplifying setup.
