1. Product Introduction
The ALF-21E-SOFTCODEC HDMI 2.0 2x1 Presentation Switcher is designed to switch
HDMI input or USB-C input to one HDMI output. It supports video resolution up to
4Kx2K@60Hz 4:4:4 8bit, 1080P, and 3D. In addition, there is smart built-in EDID setting
which can be selected by the 4-pin DIP switch on the front panel.
The switcher supports stereo and multichannel audio on the HDMI inputs. In addition to
the audio embedded in the HDMI output stream, the audio is simultaneously de-
embedded to a balanced analog audio output. It also supports device extension by
providing one type-B USB port for host connection, and two type-A USB ports for HID
devices such as a camera, microphone, keyboard etc.
The switcher features multiple methods of control. When in the AUTO mode, the
switcher will automatically switch to the first detected source device. When the active
source is removed, the switcher will switch to the lowest numbered input. The switcher
can be manually controlled by the front panel buttons and RS232 commands. CEC
allows the display device to be controlled by the front panel buttons and RS232 CEC
commands.
