3. The Control Hub
1. Status indicator
Indicates the current status using different colors and
flash modes. For details see section “The status
indicator”.
2. Power inlet
Connects to included 24V DC power supply. Make
sure connector is firmly attached.
3. Speaker output, Actiline® Digital Link
Do only connect Actiline® enabled speakers to this
output. (E.g. Opalum FLOW or STREAM series).
4. Analog subwoofer output
Optionally connect this line level output to the analog
input of an active subwoofer. At normal listening
levels adding a subwoofer is not needed thanks to the
Actisonic technology. This output will sense if a
subwoofer is attached and automatically match the
sub-woofer and Opalum speakers using a high
precision digital crossover at 80 Hz and 24 dB/octave.
If the subwoofer has it's own adjustable low-pass
filter it should be set to the highest possible
frequency in order not to interfere with the digital
crossover of the Opalum Control Hub.

Connects to analog line level equipment (e.g. mp3-
player, notebook, phones etc.) using RCA connectors.
Red connector = right, white connector = left.
