Important Safety Instructions
Please read and keep the information in the attached safety instructions supplied with the
product before starting to use the device.
Introduction
Thank you for choosing Lightware's DA-HDMI20-C series distribution amplifier.
DA4-HDMI20-C 1x4 distribution amplifier distributes and amplifies one HDMI input signal
to four HDMI outputs. This device supports HDMI video resolution up to 4K@60Hz 4:4:4,
including multichannel audio formats. Besides passing EDID information from the display,
there are multiple built-in EDID settings that can be selected with the 4-pin DIP switch on the
front panel. The device also supports firmware update through a micro-USB port.
DA8-HDMI20-C is a compact distribution amplifier with built-in EDID Management and Pixel
Accurate Reclocking, supporting DVI, HDMI 1.4, and HDMI 2.0 signals with or without HDCP
encryption. The output signal is reclocked and stabilized to remove jitter caused by long
cables or poor quality sources. Moreover, to ensure compatibility, the 4K signal on the output
is automatically down-converted to HD when HD displays are connected.
DA8-HDMI20-C features EDID Management and can emulate EDID to the video source even
if no active HDMI display is attached to the outputs. HDCP enable/disable function turns off
the HDCP capability on the input, which helps integrate certain laptops into a non-HDCP AV
environment. There are 5 factory EDID presets and one programmable memory for storing a
user EDID. This latter one can be uploaded through the USB connector. Moreover, the device
can use any EDID read from the HDMI display device connected to its video output ports.
