Product Introduction
The DIGITUS® HDMI® Matrix Switch distributes UHD video signals from up to four
HDMI® sources to two HDMI® displays such as TV sets, monitors or projectors. The
switch can process resolutions of up to 4K with a frequency of 60 Hz, including HDR
formats. The high bandwidth of 18 Gbps per HDMI® display ensures smooth
reproduction of high-resolution content with optimal quality. Supports HDMI® 2.0
and HDCP 2.2 as well as Full 3D. Conveniently switch between the different sources
using the remote control and assign them individually to the two HDMI® outputs. For
example, you can distribute video signals to 2 different rooms or record an output
signal on a recording device while watching another program at the same time. A
broad range of applications are possible: the device can be used for a variety of
commercial or private purposes. Using the existing analog and digital audio outputs,
you can also tap the audio signal of each HDMI® input and output these signals
through an amplifier or loudspeaker. You can easily switch between the various
audio features using the remote control. Output is provided through stereo RCA
connectors or the optical S/PDIF output. Numerous LEDs on the front side of the
switch show you the current configuration at a glance, and you can also manually
switch between all functions directly on the device. Spare yourself the trouble of
replugging HDMI® cables for devices such as gaming consoles, receivers or Blu-Ray
players: get the 4K HDMI® Matrix Switch from DIGITUS®.

ARC & AUDIO EXTRACTION
All the audio out is only from output A. When the ARC LED will light up
blue, the ARC is enabled and the OPTICAL can get the audio from TV.
When the ARC LED will go out, the ARC is disabled and the OPTICAL can
extract the audio from HDMI® source. Please kindly note SPDIF light is on.
SPDIF: Enable or disable Optical Digital
When the SPDIF LED will light up blue, the SPDIF is enabled and the optical
output can get the audio signal from TV or HDMI® source
(Please see the ARC details).
When the SPDIF LED will go out, the SPDIF is disabled and the OPTICAL
can’t output the audio.
2.0: When the 2.0CH LED will light up blue, the HDMI® source will read the
matrix’s built-in Audio EDID and set audio output mode into 2.0 channel
5.1: Sets audio output mode to 5.1 channel.When the 5.1CH LED will light up
blue, the HDMI® source will read matrix’s built-in Audio EDID and set audio
output mode into 5.1 channel.
PASS: Use the AUDIO EDID from Display device.When the PASS LED will light up
blue, the HDMI® source will read Audio EDID from TV. So the audio output
mode depends on TV’s EDID.

How to connect:
1) Use a HDMI® cable to connect a HD source to the HDMI® Input Port.
2) Use a HDMI® cable to connect a HD display to the HDMI® Output Port.
3) For audio connection, choose one from the following options.
a. To use HDMI® pass-through, use the HDMI® cable from step 2 to connect
audio receiver to the HDMI® Output Port. Your audio receiver will have to
output video signal to your HD display.
b. To use Toslink, use a Toslink cable to connect to audio equipment.
(Note: Toslink does not support Dolby Digital plus please change the input
source's audio output to a different setting, if needed.)
c. To use R/L, use a R/L cable to connect a stereo audio equipment.

RS-232 Control
The matrix can be controlled with either RS-232 commands. Certain switching or
format configurations can only be done using these commands. The connection
diagram is as follow:
For correct communication, set the RS232 parameters to the following setting:
Baudrate: 19200
Data Bits: 8
Parity: None
Stop Bits: 1
