•
In order to prevent signal loss or total failure of the digital signal, the length of the HDMI cables should not
exceed the values given below for the corresponding resolution.
- 1080P/60 Hz 8 Bit
15 m
- 4K/24 Hz 8 Bit
10 m
- 4K/60 Hz 8 Bit YCBCR444
3 m
•
Connect the round plug on the power adapter to the
DC 5V
power in socket (11).
•
Connect the signal sources and the display devices to a power source and turn them on.
•
If you wish to play the audio signal on an external speaker or headset with a 3.5 mm jack connection,
connect the
L/R OUT
audio output (13) to a suitable active speaker or headset.
•
If you wish to send the audio signal to an amplifier, connect the
OPTICAL OUT
audio output (14) to a
suitable amplifier.
•
When you have finished connecting the cables, insert the mains plug on the power adapter into a suitable
mains socket.
The
SERVICE
USB port (3) is designed for diagnosing faults and conducting repair work. It
is only intended for use by authorized personnel. Do not connect any chargers or other USB
devices to this port!
Setup
•
After connecting the power adapter to the mains, the
POWER
LED (9) will turn on when the mains socket
delivers a voltage.
•
The
IN
LED (8) will turn on when an HDMI signal source is connected and delivers a signal.
•
The
HDMI OUT 1
,
2
,
3
or
4
LEDs (7, 6, 5, 4) will turn on when an active HDMI display device (e.g. monitor
or TV) is connected to the corresponding output. One or more of the LEDs may turn on depending on how
many devices are connected.
Operation
a) EDID settings
The display devices and the HDMI video source use a process known as 'HDMI handshake' to exchange
information about the technical specifications of the display devices, including the manufacturer, date of
manufacture, supported resolutions (e.g. FullHD, UltraHD) and audio formats (e.g. Dolby Digital, DTS),
the number of audio channels, support for 3D signals, pixel mapping data, colour characteristics and time
information. You can configure how the HDMI splitter responds to this EDID information.
Auto mode is designed to avoid display conflicts when using several different display devices. Copy mode
should be used if there may be signal loss or if the HDMI handshake cannot be completed. Each change to
the HDMI system normally requires a new HDMI handshake between the participating devices.
•
To select the desired EDID mode, move the
EDID
switch (2) to
AUTO
or
COPY
.
AUTO
mode
•
The HDMI splitter automatically recognizes the characteristics/resolutions of the connected display
devices via EDID. It selects the video signal with the smallest resolution. This is then transferred to all 4
HDMI outputs. If the display with the smallest resolution is switched off, the HDMI splitter automatically
switches to the display with the next highest resolution.
COPY
mode
•
The HDMI splitter detects and saves the resolution of the display device connected to the
HDMI OUT 1
output (15). It then selects the matching video signal and sends it to the display devices connected to the
HDMI OUT
ports.
•
If there is no display device connected to the
HDMI OUT 1
output or the device is not EDID compatible, the
HDMI splitter will search for the next compatible signal on the
HDMI OUT 2
output, followed by the
HDMI
OUT 3
and
HDMI OUT 4
outputs until a compatible signal is found. The search is always completed in this
order and ends automatically when a compatible signal is found. The compatible signal is then transmitted
to all four output ports.
Downscaling (4K → 1080P)
•
To select the desired signal, move the DIP switch (1) for the corresponding channel to the
ON
or
OFF
position.
OFF
position
- The signal is looped through the HDMI splitter without any conversion.
ON
position
- In this setting, the 4K video signal is converted by the HDMI splitter and sent to the HDMI outputs as a
1080p video signal.
•
If Copy mode is enabled and a 4K display device is connected to the
HDMI OUT 1
output (15) (i.e. the
splitter would send a 4K video signal to all four HDMI output ports), you must convert the 4K video signal
for 1080p display devices. This also applies if a 4K display device is connected to another input in the
search hierarchy (see above).
Care and cleaning
•
This product does not contain any components that require maintenance. Never attempt to open or
disassemble it.
•
The product does not require servicing except for occasional cleaning.
•
Disconnect the HDMI splitter from the power supply and the connected devices before cleaning it.
•
Do not immerse the product in water.
•
Never use aggressive detergents, rubbing alcohol or other chemical solutions, as these may damage the
housing or cause the product to malfunction.
•
Use a dry, soft, and lint-free cloth to clean the product. Do not press too strongly on the surface, as this
may lead to scratch marks.
Disposal
Electronic devices are recyclable waste and must not be placed in household waste. At the end
of its service life, dispose of the product according to the relevant statutory regulations.
You thus fulfil your statutory obligations and contribute to environmental protection.
