HCS41A-48G – 4x1 8K HDMI & USB-C Switcher

The HCS41A-48G is a 4-input HDMI and USB-C switcher designed to simplify source selection in modern AV environments. Combining two HDMI inputs and two USB-C inputs into a single high-bandwidth HDMI output, it provides a flexible solution for meeting rooms, collaboration spaces, education environments, home cinema installations, and professional AV integration projects.

Supporting full 48Gbps HDMI 2.1 bandwidth, the HCS41A-48G delivers resolutions up to 8K30 and 4K120 with support for HDR10, HDR10+, Dolby Vision, Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and Display Stream Compression (DSC), ensuring uncompromised video quality with the latest HDMI source and display devices.

The switcher supports both automatic and manual source selection, allowing systems to automatically switch to newly connected devices or be controlled directly via the front panel, IR remote, RS232, TCP/IP, or Web GUI.

8K60 HDMI 2.1 Performance

Supporting full HDMI 2.1 bandwidth of 48Gbps, the HCS41A-48G delivers uncompromised video performance at resolutions up to 8K60 and 4K120.

Supporting HDR10, HDR10+, Dolby Vision, Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), and Display Stream Compression (DSC), the switcher is designed for the latest generation of displays, gaming systems, media players, and professional AV equipment.

Whether installed in meeting rooms, presentation spaces, or home cinema environments, the HCS41A-48G provides the bandwidth and feature set required for next-generation HDMI distribution.

EDID & HDCP Management

Reliable HDMI distribution depends on proper EDID and HDCP communication between connected devices. Comprehensive EDID management allows the installer to optimise source output formats using display pass-through or predefined EDID profiles.

Advanced HDCP management further improves compatibility between source and display equipment, helping to eliminate common HDMI interoperability issues.

Built-In Test Pattern Generator

An integrated Test Pattern Generator provides a convenient way to verify displays, cabling, and system operation without requiring an external signal generator.

Multiple resolutions and pattern types are available, making commissioning and troubleshooting significantly easier during installation. The built-in patterns allow installers to quickly isolate display, cabling, or source-related issues, reducing installation time and improving system reliability.

 Video Keep Alive (VKA)

The built-in Video Keep Alive feature maintains a stable video output whenever the source signal is lost. When activated, the internal test pattern generator automatically takes over to prevent displays or projectors from losing sync.

This can be particularly beneficial in projector installations where signal loss could otherwise trigger lengthy resynchronisation or shutdown cycles.

Intelligent Auto-Switching

The HCS41A-48G provides two independent Auto-Switching modes, allowing installers to select the most appropriate switching behaviour for the application.

5V Detection Mode automatically switches to a source when HDMI or USB-C 5V power is detected, making it ideal for laptops and devices that remain powered while connected.

Video Signal Detection Mode switches only when an active video signal is present, preventing unwanted source changes from connected but inactive devices.

Both modes can be configured through the Web GUI, providing greater flexibility across meeting rooms, education environments, and collaborative workspaces.

eARC Support

The HCS41A-48G supports Enhanced Audio Return Channel (eARC), allowing high-quality audio formats to be returned from compatible displays and distributed through the system.

This makes the switcher ideal for home cinema, conference room, and presentation environments where advanced audio integration is required.

Analog & Digital Audio De-Embedding

Integrated audio de-embedding provides both digital SPDIF and analogue stereo outputs, allowing audio to be extracted from the selected HDMI source for connection to amplifiers, DSPs, audio matrices, and conferencing systems.

This provides additional flexibility when integrating displays that do not provide suitable audio outputs.

Flexible Control & Diagnostics

Comprehensive control and monitoring features are available via the Web GUI, TCP/IP, RS232, IR remote control, and front panel controls.

The built-in web interface provides both Admin and User login modes, allowing installers to protect system configuration while still providing day-to-day operational control for end users.

Additional diagnostic and control features include:

• EDID configuration
• HDCP management
• Network configuration
• Input selection
• Auto-switching configuration
• Test pattern selection
• Video Keep Alive configuration
• Display mute control
• Audio management
• Device status monitoring
• System configuration and maintenance

USB-C Integration & Power Delivery

Two USB-C inputs provide seamless connectivity for modern laptops, tablets, and mobile devices without requiring HDMI adapters.

Input 4 supports USB-C Power Delivery up to 100W when connected to an external PD power supply, allowing compatible devices to be charged while simultaneously transmitting video.

This reduces cable clutter and improves the user experience in meeting rooms and collaborative workspaces.
