Introduction
Overview
The ATEN VP1420/VP1421 is a multi-in-one presentation switch that integrates
a video matrix switch, True 4K scaler, analog-to-digital converter, audio
processor (VP1420), HDBaseT Extender (VP1421), and audio DSP (VP1421)
into one compact device. With the four analog/digital inputs to 2 HDMI True 4K
outputs (VP1420) / 1 HDMI & 1 HDBaseT outputs (VP1421), the VP1420/
VP1421 is designed to boost the efficiency and impact of professional
presentations.
With its versatile control via the front panel, IR remote controller, control
protocols (RS-232 and Telnet), and web GUI, the VP1420/VP1421 reduces not
only system device count, but also lowers operation complexity. The VP1420/
VP1421 is suitable for all meeting space and education environments, such as
huddle rooms, classrooms, training rooms, or any other presentation setting,
such as exhibition galleries or hotels.
