Aten VP1421 4 x 2 True 4K Presentation Matrix Switch

Overview

The VP1421 is a multi-in-one presentation switch that integrates a video matrix, True 4K scaler, HDBaseT extender, audio DSP, and analog-to-digital converter functions into a single compact enclosure, ideal for meeting rooms and educational spaces.

True 4K, HDR Visual Clarity

Supports resolutions up to 4096 x 2160 @ 60Hz (4:4:4) and HDR to deliver vivid content in every presentation.

Smooth AV Switching Scaled to Perfection

Connect up to 4 sources (1 HDBaseT, 2 HDMI, 1 VGA), smoothly switch between them and display contents scaled perfectly to True 4K and 1080p simultaneously.

HDBaseT Extended Transmission over One Cable

Simplifies cabling and transmits AV, power, and bi-directional RS-232 and IR control signals up to 140m via Cat 6/6a or ATEN 2L-2910 Cat 6 cables (applying both HDBaseT input and output ports).

Built-in Advanced Audio DSP

Supports microphone input with selectable 48V Phantom Power and allows microphone input to be mixed with program audio and embedded into display output while automatically reducing program audio to enhance speech audibility.

Flexible Audio Embedding/De-Embedding

Supports stereo audio embedding into HDMI output or separation to Audio Line Out and Optical Audio Out. Extract HDMI and HDBaseT audio to different audio outputs as well to ease adaptation to you preferred audio setup.

Versatile Control, Streamlined Operations

Control via front-panel pushbuttons, IR remote, web-based GUI and any control interface via RS-232, Ethernet, and Contact Closure to streamline your operations.
