The KanexPro 1x8 Distribution Amplifier (SP-HDPOC1X8) is a versatile 18Gbps HDMI 1x8 Splitter designed to distribute a single HDMI source signal to up to eight display devices. This device is ideal for various professional and home theater applications where a single high-definition video source needs to be displayed on multiple screens simultaneously. It supports advanced video resolutions and audio formats, ensuring a high-quality viewing and listening experience across all connected displays.
Function Description:
The core function of this device is to take one HDMI input and replicate it across eight CAT outputs, along with one HDMI loop output. This allows for flexible distribution of video and audio signals over longer distances using CAT6/6a/7 cables. The integrated Power over Cable (PoC) function simplifies installation by powering the receiver units directly from the transmitter, eliminating the need for separate power adapters at each display location.
The transmitter unit features a comprehensive set of ports and controls. The HDMI input connects to your source device, such as a DVD player, set-top box, or gaming console. An HDMI loop output is provided for connecting a local display, allowing you to monitor the source content directly at the transmitter location. Eight CAT outputs are available for connecting to the corresponding CAT IN ports on the receiver units, distributing the HDMI signal over long distances.
For audio flexibility, the transmitter includes both coaxial and L/R analog audio outputs. These de-embedded audio outputs allow you to connect to an external amplifier or speaker system, providing an enhanced audio experience independent of the HDMI displays. This is particularly useful in setups where a dedicated audio system is preferred.
The device also supports one-way IR control signal pass-through. An IR OUT port on the transmitter connects to an IR Blaster cable, which can transmit IR signals from the CAT receiver back to the source device. This enables remote control of the source device from the display locations, adding convenience to the system.
On the receiver side, each unit features an HDMI output for connecting to a display device (TV or projector) and a CAT IN port for receiving the signal from the transmitter. An IR IN port on the receiver connects to an IR Receiver cable, which picks up IR signals from your remote control and sends them back to the transmitter.
Usage Features:
The KanexPro 1x8 Distribution Amplifier offers several features that enhance its usability and performance:
- Extended Signal Transmission: The device can extend HDMI signals over significant distances using a single CAT6/6a/7 cable. This is crucial for large installations where displays are far from the source. The transmission distances vary based on resolution: up to 35 meters for 4K2K@60Hz, 50 meters for 4K2K@30Hz, and 60 meters for 1080P@60Hz.
- High-Resolution Video Support: It supports video resolutions up to 4K2K@50/60Hz 4:4:4, ensuring compatibility with the latest high-definition content and displays. It also supports various color depths, including 8-bit, 10-bit, and 12-bit, and color spaces like RGB, YCbCr 4:4:4 / 4:2:2, and YUV 4:2:0.
- Advanced HDR Support: The device is compatible with HDR10, HDR10+, HLG, and Dolby Vision, delivering vibrant colors and enhanced contrast for a more immersive viewing experience.
- Comprehensive Audio Support: It supports a wide range of HD audio formats, including LPCM, Dolby Digital/Plus/EX, Dolby True HD, DTS, DTS-EX, DTS-96/24, DTS High Res, DTS-HD Master Audio, and DSD. The de-embedded digital and analog audio outputs provide additional flexibility for audio routing.
- EDID Management: The device features advanced EDID management capabilities, allowing users to select predefined EDID modes or copy EDID from connected displays. This ensures optimal compatibility between the source and display devices, preventing common display issues. An EDID DIAL switch on the side panel of the transmitter allows for easy selection of EDID modes.
- One-Way PoC Function: The Power over Cable (PoC) function simplifies installation by allowing the transmitter to power the receiver units through the CAT cable. This eliminates the need for separate power adapters at each receiver location, reducing cable clutter and simplifying power management.
- IR Control Pass-Through: The one-way IR control signal pass-through enables remote control of the source device from any of the display locations. This provides convenience, especially when the source device is located in a different room or cabinet.
- Compact Design: Both the transmitter and receiver units feature a compact design, making them easy to integrate into various setups without occupying excessive space.
- LED Indicators: The transmitter and receiver units are equipped with LED indicators that provide visual feedback on the device's status, including power, HDMI input connection, HDMI loop output connection, CAT output connection, and data signal status (with or without HDCP). These indicators help in troubleshooting and monitoring the system's operation.
Maintenance Features:
- Firmware Update: The device includes a SERVICE port (Micro USB) on the transmitter and receiver units, which is used for firmware updates. This allows for future enhancements, bug fixes, and compatibility improvements, ensuring the device remains up-to-date with evolving technology standards.
- Serial Port Command Control: The SERVICE port also supports serial port command control (ASCII commands). This feature allows for advanced configuration and control of the device via a PC, providing a powerful tool for system integrators and advanced users. Commands are available for power control, system status queries, EDID management, and output stream control.
- Surge Protection: While the device itself is robust, it is highly recommended to use a surge protection device. This protects the sensitive electrical components from damage caused by electrical spikes, surges, electric shock, or lightning strikes, thereby extending the life of the equipment.
- User Manual: A comprehensive user manual is included, providing detailed instructions on connection, operation, and troubleshooting. This resource is invaluable for setting up and maintaining the device effectively.
