Item no. 1274940
Intended use
This product is used to convert an HDMI-compatible AV signal into an SDI signal. The external wall plug
transformer enclosed is used to supply the power.
Always observe the safety instructions and all other information included in these operating instructions.

Safety instructions
Damages due to failure to follow these operating instructions will void the warranty! We
do not assume any liability for any resulting damage!
We shall not accept liability for damage to property or personal injury caused by incor-
rect handling or non-compliance with the safety instructions! The warranty will be void in
such cases.
a) General
• Unauthorised conversion and/or modification of the product is not allowed for safety and approval reasons
(CE). Do not disassemble the product.
• Any maintenance or repair work may only be performed by an expert.
• Do not leave packaging material carelessly lying around, since it could become a dangerous plaything for
children.
b) Wall plug transformer
• The design of the wall plug transformer complies with Protection Class II. Use only a standard mains
socket as the power source for the wall plug transformer.
• The mains socket into which the wall plug transformer is plugged must be easily accessible.
• Use only the wall plug transformer supplied to power the converter.
• Do not pull the wall plug transformer from the mains socket by pulling on the cable. Hold it on the sides of
the casing and pull it out of the mains socket.
• Never touch a wall plug transformer that shows signs of damage, as this could cause a fatal electric shock!
First, switch off the mains voltage to the socket to which the wall plug transformer is connected (switch
off at the corresponding circuit breaker or remove the safety fuse or switch off at the corresponding RCD
protective switch, so that all poles of the mains socket are disconnected).
You can then unplug the wall plug transformer from the mains socket. Dispose of the faulty wall plug trans-
former in an environmentally friendly way, do not use it any more. Replace it with a wall plug transformer
of the same design.
c) Operation
• The product is not a toy. Devices operated using mains voltage should not be used by children. Particular
care must therefore be exercised if children are around.
Use the product where it is out of the reach of children.
• The product is intended for use only in dry, indoor locations. No part of the product should become damp
or wet; never handle it if your hands are wet!
Wall plug transformers pose the potential risk of a fatal electric shock!
• Avoid the following adverse conditions at the location of installation and during transport:
- Dampness or excessive humidity
- Extreme cold or heat, direct sunlight
- Dust or flammable gases, fumes or solvents
- Strong vibrations, impacts or blows
- Strong magnetic fields such as those found in the vicinity of machinery or loudspeakers
• Do not place objects on the converter; never cover the converter.
• Choose a stable, even, flat and sufficiently large surface for the installation.
• Never use the product immediately after moving it from a cold room into a warm one. The condensation
that forms might damage the product. The wall plug transformer also poses a risk for a potentially fatal
electric shock!
Allow the product to reach room temperature before connecting it to the power supply and putting it into
use. This may take several hours.
• When setting up the product, make sure that the cables are neither kinked nor pinched.
• Handle the product with care; it can be damaged by impacts, blows or falls even from a low height.
Version 10/14
Connection and start-up
• Connect the converter’s HDMI input to the corresponding output, e.g. of a Blu-ray player.
• Connect the converter’s BNC connector to an SDI input, e.g. on a corresponding monitor, using a suitable
SDI cable. The converter sends the SDI signal to both outputs; enabling two devices to be connected at
the same time.
• Connect the circular low-voltage plug of the wall plug transformer into the corresponding socket on the
converter.
• Plug the wall plug transformer into a mains socket.
• Switch on all devices connected to the converter.
Make sure that the audio signal on the converter has a sampling rate of 48 kHz (PCM) (other
audio signals, such as AC-3, DTS, 22 kHz, 32 kHz, 44.1 kHz or 96 kHz, are not supported).
If no audio signal is transferred, adjust the playback device accordingly (48 kHz, PCM).
Cleaning
Unplug the wall plug transformer from the mains socket before cleaning the product,.
Use a clean, dry, soft cloth for cleaning. Do not use aggressive cleaning agents, as these can cause discol-
ouration. To prevent scratch marks, do not press too strongly on the surface when cleaning.
Dust can easily be removed using a clean, long-haired brush and a vacuum cleaner.
Disposal
Electrical and electronic products do not belong in your regular household waste.
Please dispose of the product, when it is no longer of use, according to the current statutory
requirements.
