Chapter 2: Overview
2. Overview
2.1 Introduction
The Presentation Switcher - HDBaseT, 4 x 1 is an advanced four-input, multi-format
converter, switcher, scaler, and extender with built-in 4K scaling, in a compact 1U
half-rack enclosure. It offers two HDMI inputs, one DP input, one VGA input with ste-
reo audio, an HDMI with HDBaseT mirrored output to allow signal extension over CATx
cable to reach a remote display, or an additional HDBaseT signal management system.
One balanced stereo audio breaks out from HDMI output.
NOTE: Scaling is only supported on HDMI output. For scaling on HDBaseT output,
please use with VX-1003-TX scaling receiver.
The Switcher supports auto switching and has a built-in 4K @ 30 Hz scaler in HDMI
output, with rotary switch scaler adjustment, and allows seamless switching to enhance
presentations. Its built-in CEC controller automatically turns the display on/standby by
auto-detecting the input signal status. You can also control the Switcher via pushbut-
tons on the front panel, contact closures, and RS-232 API.
The Switcher simplifies classroom and small office system integration, for installation
beneath conference tables and in lecterns, to provide localized presentation switching
support.
