Need help?Do you have a question about the KanexPro SP-HDPOC1X4 and is the answer not in the manual?
The KanexPro 1x4 Distribution Amplifier (SP-HDPOC1X4) is a versatile 18Gbps HDMI 1x4 Splitter designed to distribute a single HDMI source signal to up to four display devices. This system is engineered for optimal performance and safety, ensuring reliable signal transmission over extended distances. It supports a wide range of video resolutions, including 4K2K@50/60Hz 4:4:4, and incorporates advanced features for enhanced user experience and system management.
The core function of this device is to split and extend an HDMI signal. The transmitter unit takes one HDMI input and provides one HDMI loop output and four CAT outputs. These CAT outputs connect to individual CAT receivers, each capable of outputting an HDMI signal to a display device. This setup allows for the distribution of high-quality video and audio to multiple screens simultaneously.
The system supports HDMI 2.0, HDCP 2.2 / 1.x, and DVI 1.0 compliance, ensuring compatibility with a broad array of modern and legacy equipment. It handles an 18Gbps video bandwidth, making it suitable for demanding applications that require high data rates. Video resolutions up to 4K2K@50/60Hz 4:4:4 are supported, providing crisp and detailed imagery. Furthermore, it supports various advanced video technologies such as 3D, HDR, HDR10+, HLG, and Dolby Vision, delivering a rich visual experience.
Audio pass-through is robust, supporting up to 7.1CH 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. Additionally, the device offers digital and analog audio de-embedded outputs (Coaxial and L/R Stereo Mini-jack), allowing for flexible integration with external audio systems like amplifiers or speakers.
Signal transmission distance is a key feature, extending HDMI signals up to 35 meters for 4K2K@60Hz, 50 meters for 4K2K@30Hz, and 60 meters for 1080P@60Hz over a single CAT6/6a/7 cable. This capability makes it ideal for installations where displays are located far from the source.
The system also includes a Power over Cable (PoC) function, which simplifies installation by allowing the transmitter to power the receivers via the CAT cable, eliminating the need for separate power adapters at each receiver end. This one-way PoC function streamlines cabling and reduces clutter.
The KanexPro 1x4 Distribution Amplifier is designed for ease of use and flexible installation. The front panel of the transmitter features an ON/OFF power switch and LED indicators for power, HDMI input (IN LED), HDMI loop output (LOOP LED), and each of the four CAT outputs (OUT LED 1-4). These LEDs provide immediate visual feedback on the operational status and connection integrity of the system.
The rear panel of the transmitter includes the HDMI input port, HDMI loop output port, four CAT output ports, Coaxial audio output, L/R audio output, a SERVICE port (Micro USB for firmware updates), and an IR OUT port. The side panel of the transmitter houses an EDID DIAL switch for advanced EDID management and another SERVICE port for firmware updates or serial port command control.
Each CAT receiver unit is compact and features an HDMI output port, a CAT IN port, an IR IN port, and a DC 12V power input. LED indicators on the receiver include a Power Indicator Lamp (Green), a Link Signal Indicator Lamp (Green) to show connection status with the transmitter, and a Data Signal Indicator Lamp (Orange) to indicate HDMI signal presence and HDCP status.
IR control signal pass-through is a significant feature, enabling control of the source device from the display location. The system includes an IR Blaster Cable and IR Receiver Cables. The IR Blaster connects to the transmitter's IR OUT port and is placed near the source device's IR sensor. The IR Receiver Cables connect to the CAT receiver's IR IN port and are placed near the display, allowing a remote control to send commands back to the source. The IR pin definition clarifies the wiring for IR signal, power, and grounding, ensuring proper setup.
Advanced EDID management is available through the EDID DIAL switch on the transmitter's side panel. Users can select from a predefined list of EDID settings, including various resolutions, audio formats, and HDR capabilities, to ensure optimal compatibility between the source and display devices. This feature helps resolve common display issues by allowing the user to force a specific EDID to the source. The EDID settings range from basic 1080P Stereo Audio 2.0 to advanced 4K2K60Hz 4:4:4 HD Audio 7.1 HDR, and even options to copy EDID from the HDMI loop output or individual CAT outputs.
The device also supports ASCII command control via the SERVICE port, allowing for remote management and configuration from a PC. Commands can be sent to power on/off the device, reboot, get device status, check firmware version, and manage input/output link statuses, HDCP settings, and EDID modes. This provides a powerful tool for system integrators and advanced users to control and monitor the device.
The KanexPro 1x4 Distribution Amplifier is designed for long-term reliability and ease of maintenance. The product includes a SERVICE port (Micro USB) on both the transmitter and receiver units, primarily for firmware updates. This allows the device to stay current with the latest features, bug fixes, and compatibility improvements, extending its lifespan and ensuring optimal performance with evolving AV technologies.
The robust metal enclosure of both the transmitter and receiver units provides durability and protection for the internal components. The compact design of the units facilitates easy and flexible installation, reducing the likelihood of physical damage during setup or operation.
The LED indicators on both the transmitter and receiver units serve as valuable diagnostic tools. For instance, the IN LED on the transmitter indicates an active HDMI source connection, while the LOOP LED confirms an active display on the loop output. The OUT LEDs on the transmitter show active connections to the CAT receivers. On the receiver, the Link Signal Indicator Lamp (Green) confirms a successful connection with the transmitter, and the Data Signal Indicator Lamp (Orange) provides information about the HDMI signal and HDCP status. Flashing patterns on these LEDs can indicate specific issues, such as no HDMI signal or lack of HDCP, aiding in quick troubleshooting.
The inclusion of a user manual provides comprehensive instructions for installation, operation, and troubleshooting, empowering users to maintain the system effectively. The recommendation to use surge protection devices highlights a proactive maintenance approach, protecting the sensitive electrical components from damage due to electrical spikes, surges, electric shock, or lightning strikes, thereby extending the life of the equipment.
The ASCII command control feature also contributes to maintenance by allowing remote diagnostics and configuration. Users can query the device's status, check link connections, and reset settings to factory defaults, which can be crucial for remote troubleshooting without physical access to the device.
Overall, the KanexPro 1x4 Distribution Amplifier is a well-rounded solution for HDMI signal distribution, offering a rich set of features for performance, usability, and maintainability in various professional and home theater environments.
