Connection and start-up
a) Setup and connection
• Using a suitable HDMI-compatible cable, connect the HDMI input (9) to the HDMI output on
a player, e.g. a Blu-ray player, a game console, etc. Using a suitable adapter (not included in
the delivery), you can also connect to the DVI port on a PC or notebook.
• Connect your TV or monitor to the HDMI output (1).
• A 3.5 mm stereo jack plug (10) is available for feeding an analogue audio signal. Connect, for
instance, the analogue audio output (line level) on your player (e.g. a PC) to this port.
Should a digital audio signal be used (2-channel or also 5.1), then this can be fed to the
TOSLINK jack (8).
• Connect the circular low-voltage plug of the power adapter provided to the corresponding
socket (7) of the audio inserter.
• Place the audio inserter on a solid, horizontal surface. Protect the surfaces of valuable furni-
ture by using an appropriate underlay to avoid scratches and pressure marks.
The delivery includes 4 rubber feet. Glue them to the underside of the housing of the audio
inserter (one rubber foot on each corner), if necessary.
• Plug the power adapter into a mains socket.
b) Switch on/off
Press the On/Off switch (6) of the audio inserter to turn the device on or off. In the switched-on
status, the “Power” LED is lit up.
The “Link” (3) LED lights up when a HDMI signal is detected at the input.
A HDMI or audio signal cannot be transmitted if the audio inserter is turned off.
c) Selecting the audio mode
The audio mode is selected with the sliding switch (5).
“HDMI” switch position:
The HDMI signal is looped through without being changed. The “Bypass” LED (2) lights up.
“L/R” switch position:
The audio signal at the analogue input (10) is inserted into the HDMI signal.
“Optical” switch position:
The audio signal at the digital input (8) is inserted into the HDMI signal.
