Introduction
Overview
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.
With 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 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 to control 2 displays at the same time and is designed to boost
the efficiency and impact of professional presentations. The VP3520 provides
users the flexibility of using both active and passive speakers with its stereo
line out port, coaxial port, and 2 x 10 W power amplifiers.
As for the control functions, the VP3520 offers users the multiple control
options such as the front-panel pushbuttons, IR remote control, RS-232
commands, and web-based GUI. Moreover, the VP3520 enables to control of
AV devices such as TV displays, projectors, and monitors. It is ideal for all
meeting space and education environments, including huddle rooms,
classrooms, training rooms, or any other presentation setting such as in
exhibition galleries or hotels.
