Connection Diagram (Example 1)
When the ARC/eARC function is turned off, the connection diagram is as follows. In this
situation, the optical audio or L/R audio is from the selected input channel.

BZBGEAR BG-8K-HS41A PRODUCT MANUAL
Connection Diagram (Example 2)
When the ARC/eARC function is enabled, select input port 1 by pressing the "SWITCH"
button on the front panel or the "1" button on the IR remote. Then, connect the "IN 1
(eARC)" port to a soundbar to output the audio signal returned from the "OUT (eARC)" port,
as shown in the figure below. For example, when the user watches a TV app, the switcher
will pass through the TV eARC/ARC audio to the soundbar. At this point, the optical audio
or L/R audio comes from the returned audio of the 8K TV connected to the OUT (eARC)
port.
Note:
If the 8K TV supports the ARC/eARC function, the Soundbar will receive the audio signal
from the TV and emit the sound. If the TV does not support ARC/eARC, the Soundbar will
not emit sound.
When the IN 1 channel is selected as the input source, it will be locked. This means that
other input channels will not be automatically identified, even if Auto Switching is enabled.
For example, if a source device is connected to the IN 3 channel, it will not be automatically
used as the signal source because the IN 1 channel is locked.

Connection Diagram (Example 3)
When the ARC/eARC function is enabled, select input port 2, 3, or 4 by pressing the
“SWITCH” button on the front panel or using the buttons on the IR remote. If you connect
the “IN 1(eARC)” port to a soundbar, it will output the audio signal from the selected input
channel. At this time, the optical audio or L/R audio will also come from the selected input
channel.
Note: In this situation, the soundbar will not output audio from the 8K TV connected to
the OUT port, regardless of whether the 8K TV supports ARC/eARC.
