The ATEN VP3520 is a multi-in-one presentation matrix switch that integrates a video matrix switch, 4K scaler, HDBaseT extender, and audio DSP functions into one compact device that easily mounts under a table or in a rack. The VP3520 seamless presentation matrix switch with control features the True 4K video resolutions of 4096 x 2160 / 3840 x 2160 @ 60 Hz (4:4:4) and HDR technology, guaranteeing crystal-clear images across two displays. The VP3520 supporting 4K @ 60 Hz, HDMI, and HDCP 2.2 features Seamless Switch™ that employs an FPGA matrix architecture that ensures continuous video streams, real-time control, and stable signal transmissions. With a built-in high-performance 4K scaler, the VP3520 easily converts various input resolutions into various output display resolutions, giving viewers the best video and picture quality across the two displays.\nWith flexible audio de-embedding, the VP3520 is designed with the audio routing flexibility to meet different application requirements. In a simple setup, HDMI audio can be connected and switched directly to display audio. For a more complex setup, the HDMI audio can be de-embedded to Audio Line Out in order to connect to your preferred in-room audio equipment. Equipped with 5 digital inputs to one HDBaseT and one HDMI True 4K separate outputs, the VP3520 enables users to control 2 displays at the same time and is designed to boost the efficiency and impact of professional presentations. The VP3520 provides users with the flexibility of using both active and passive speakers with its stereo line out port, coaxial port, and 2 x 10 W power amplifiers.\nAs for the control functions, the VP3520 offers users multiple control options such as the front-panel pushbuttons, IR remote control, RS-232 commands, and web-based GUI. Moreover, the VP3520 enables the control over AV devices such as TV displays, projectors, and monitors. It is ideal for all meeting spaces and education environments, including huddle rooms, classrooms, training rooms, or any other presentation setting such as exhibition galleries or hotels.
