ATEN VP1421 4 x 2 True 4K Presentation Matrix Switch

Perfect clarity of presentation - 4 x 2 True 4K Presentation Matrix Switch with scaling, DSP, and HDBaseT-Lite - The VP1421 is a multi-in-one presentation switch that integrates video matrix, true 4K scaler, HDBaseT extender, audio DSP, and analog-to-digital converter functions into a single compact housing, ideal for meeting rooms and educational spaces.

• True 4K, HDR Visual Clarity – Supports resolutions up to 4096 x 2160 at 60 Hz (4:4:4) and HDR, delivering vibrant content in every presentation.
• Smooth AV switching perfectly scaled – Connect up to 4 sources (1 HDBaseT, 2 HDMI, 1 VGA), switch smoothly between them, and display content perfectly scaled to True 4K and 1080p simultaneously.
• HDBaseT extended transmission over a single cable – Simplifies cabling and transmits AV, power, and bidirectional RS-232 and IR control signals up to 140m over Cat 6/6a or ATEN 2L-2910 Cat 6 cables (both via HDBaseT input and output ports).

• Integrated Advanced Audio DSP – Supports microphone input with selectable 48V phantom power and allows mixing the microphone input with the program audio and integrating it into the display output while automatically reducing the program audio input to enhance speech intelligibility.
• Flexible audio embedding/de-embedding – Supports embedding stereo audio into the HDMI output or separating audio line out and optical audio out. Extract HDMI and HDBaseT audio to different audio outputs to facilitate adaptation to your preferred audio configuration.
• Versatile control, optimized operation – Control via buttons on the front panel, IR remote, web-based GUI, and any control interface via RS-232, Ethernet, and contact closure to optimize your operation.

Analog/Digital AV Matrix Switch

• Supports multi-format 4 inputs – 2 HDMI, 1 HDBaseT, and 1 VGA input
• 1 HDMI and 1 HDBaseT outputs
• Audio embedding – Stereo audio can be embedded into display output or separated to stereo line out and optical audio outputs
• Audio de-embedding – HDMI/HDBaseT audio can be extracted to stereo line out
• Integrated audio DSP – supports microphone input with selectable 48V phantom power and allows mixing the microphone input with the program audio and integrating it into the display output
• Automatically reduces program audio when a microphone signal is detected
• Automatic switching – detects and automatically switches to a new source as soon as it is connected

High-resolution video with optimal performance

• Excellent video quality – True 4K resolutions up to 4096 x 2160 at 60 Hz (4:4:4) (HDMI) / 4096 x 2160 at 60 Hz (4:2:0) (HDBaseT)
• Supports 4K HDR
• Scaler – supports video upscaling to 4K for Display A and downscaling to 1080p for Display B
• EDID Expert™ – automatically selects the optimal EDID settings for smooth power-up, high-quality display, and the best video resolution across all connected devices
• HDMI 2.0 (3D, Deep Color, 4K); HDCP 2.2 compliant

Versatile, optimized operation

• Multiple control options – flexible control via buttons on the front panel, IR remote, RS-232, and web-based GUI over Ethernet
• View and control via the ATEN Video Presentation Control App in a fast and agile manner
• Bidirectional RS-232 and IR channel – allows control of AV devices over the HDBaseT connection without additional cabling
• Supports standby mode for energy saving and quick wake-up
• Consumer Electronics Control (CEC) support
• Integrated contact input and LED output for controlling the keyboard via VPK104 contact closure remote pad

Extended transmission over a single cable

• Remote transmission – transmit digital AV signals, bidirectional RS-232, and IR control signals up to 140m* over Cat 6/6a or ATEN 2L-2910 Cat 6 cables
• Power over HDBaseT (POH) – remote powering over existing communication cable with selectable power supply
• Note: This is achieved via both the HDBaseT input and HDBaseT output ports on the VP1421, which extend the transmission up to 70m each.
