I. Product Overview: Multi-Source HD Switching, Stable & Efficient Transmission

The HDMI HD Matrix by Qtenboard is a professional signal distribution and switching device developed for "multi-signal sources + multi-display terminals" scenarios. It fully supports the HDMI 1.3a protocol, enabling flexible switching and synchronous transmission of multiple HD audio and video signals.

Equipped with a broadcast-grade 6.5GHz switching chip, the device is compatible with multiple resolutions including 1080p@24/30/50/60/120Hz and supports lossless audio formats such as Dolby True HD and DTS-HD Master Audio.

It also features core functions like EDID adaptive function, HDCP decryption, and ESD electrostatic protection, and is available in 1U/2U rack-mounted chassis options, meeting the HD signal management needs of conference rooms, monitoring centers, multimedia classrooms, and exhibition halls.

II. Core Features: Professional-Grade Performance, Fully Adaptable to Needs

1. Synchronous Transmission of HD Audio & Video, Excellent Picture & Color Quality

• Full-Channel HD Support: Each input/output channel is compatible with the HDMI 1.3a protocol, supporting all standard resolutions including 480i/576i/480p/576p/720p/1080i/1080p@24/30/50/60/120Hz, meeting both HDTV and HDPC scenario requirements.
• Enhanced Color Depth: Supports Deep Color 24/30/36/48-bit, paired with RGB444, YUV444, YUV422 color spaces and the X.v.Cruor extended color gamut standard, restoring more delicate color gradients and avoiding picture discoloration or distortion.
• Lossless Audio Transmission: Supports embedded audio and is compatible with HD audio formats such as LPCM 7.1-channel, Dolby True HD, Dolby Digital +, and DTS-HD Master Audio, enabling synchronous switching of audio and video without delay or stuttering.

2. Broadcast-Grade Chip, Stable & Reliable Operation

Adopts an American broadcast-grade 6.5GHz switching chip with higher integration and stronger anti-interference capabilities. It effectively avoids black screens or screen flickering during signal switching, ensuring stable 24/7 continuous operation to meet the high reliability requirements of professional scenarios.

3. Real-Time Status Visualization, Intuitive & Convenient Operation

The front panel of the device is equipped with an LCD screen that can display signal switching status (e.g., current input/output channel matching) and system configuration information (e.g., control mode, EDID status) in real time. There is no need to connect external devices to monitor the device's operating status, simplifying operation and maintenance.

4. Multiple Chassis Specifications, Adaptable to Different Scenarios

Adopts a standard rack-mounted design, supporting 1U and 2U chassis specifications. The selection is based on the number of input/output channels:

• 1U Chassis: Supports 4-in-4-out (QM-HD4V4HD) and 8-in-8-out (QM-HD8V8HD), suitable for small to medium-sized scenarios (e.g., small conference rooms, classrooms).
• 2U Chassis: Supports 8-in-16-out (QM-HD8V16HD), 16-in-16-out (QM-HD16V16HD), 8-in-32-out (QM-HD8V32HD), and 16-in-32-out (QM-HD16V32HD), meeting the needs of large-scale monitoring centers, exhibition halls, and other multi-terminal scenarios.

5. Four Control Modes, Flexibly Adapting to Different Needs

Supports four control methods: key control, RS-232, IR remote control, and TCP/IP (optional), covering local, remote, and central control scenarios:

• Key control: Physical buttons on the front panel for direct channel switching;
• RS-232: Supports connection to central control systems for automated control;
• IR remote control: Long-distance wireless operation for temporary adjustments;
• TCP/IP: Supports LAN control and can be linked with smart systems (optional function).

6. Multi-User Synchronous Control, Real-Time Status Consistency

Up to 16 PC clients in the same LAN can control one matrix device simultaneously, and the signal switching status between clients and the matrix can be synchronized in real time. This avoids operation conflicts among multiple users and improves team collaboration efficiency (e.g., multi-station collaborative management in monitoring centers).

7. EDID Adaptive Function, Solving Compatibility Issues

Built-in EDID reading/writing and adaptive functions, which can automatically identify parameters such as the resolution and color gamut of display terminals, dynamically matching the signal output specifications. This completely eliminates problems such as "incomplete screen display, black borders, and resolution incompatibility" and is compatible with various display devices such as monitors, projectors, and TVs.

8. HDCP Decryption, Supporting Encrypted Signal Sources

Each input channel supports HDCP 1.3 protocol decryption, allowing normal connection to encrypted signal source devices such as Blu-ray DVDs, encrypted set-top boxes, and HD players. This ensures the normal transmission and display of genuine HD content without signal blocking or black screens.

9. Open Secondary Development, Adapting to Custom Needs

Adopts open control codes and supports multiple industry-standard protocols, allowing users to conduct secondary development based on their own needs (e.g., connecting to their own central control systems, customizing operation interfaces), flexibly adapting to function expansion in special scenarios.

10. ESD Electrostatic Protection, Extending Device Lifespan

Features professional ESD electrostatic protection design, which can withstand human body discharge mode: ±8kV (air gap discharge), ±4kV (contact discharge). It effectively resists electrostatic interference, prevents damage to internal chips caused by static electricity, and extends the device's service life in dry environments.
