care.
Burn In Time:
Loudspeakers are equipped with moving parts. Therefore, you need a so-called Einspielzeit until
the moving parts can move within their tolerances.
Play back broad-spectrum signals for at least 2 days. It is best to use special burn-in CDs (with
"pink noise") or your FM radio after placing it on an unoccupied frequency.
Please note that after a prolonged period of inactivity, the moving parts can return to their
original "Rigid". Then give your subwoofer a few hours' warm up time by playing music, and
you'll surely notice the increase in fidelity!

the subwoofer switches to standby after 15 minutes (this value can be changed in
the settings menu). If music signal is detected, the subwoofer automatically switches on again.
If you disconnect the subwoofer from the mains you have nothing to consider. Restarting /
plugging brings your subwoofer back to its last state. All parameters (except the subwoofer lock -
see above) are stored in a long-term memory that does not lose its contents.

Profile
The AUDIUM Sub 12 has predefined profiles which simplify a combination with
other AUDIUM loudspeakers. To do this, select the menu item "Profiles". In the
following submenu you will find an entry for Comp3, 5, 7, 8 and 9. If you select
the entry (by pressing the rotary knob) you will be given the option to select the item "Load" or
"Back".
" Load" then loads the selected profile. This means that the current values of frequency, slope,
high-pass, phase and polarity are overwritten with the values of the profile. The menu entry then
changes to "Active" (until you change one of the parameters).
" Back" lets you return to the profile selection.
If you want to save your current settings before loading a predefined profile, save them in one of
the 3 user memories
User Memories
The AUDIUM Sub 12 has 3 user memories in which all set parameters can be
stored. This means that in addition to frequency, slope, high-pass, phase and
polarity, the selected input, volume and all other parameters such as display brightness, mute
duration, ...
Select the menu item "Memory". In the following submenu you will find an entry for User1, User2
and User3. If you select the entry (by pressing the rotary knob) you will be given the option to
select the item "Load", "Save" or "Back".
"Load" then loads all settings from the user memory.
"Memory" stores all settings in the user memory.
"Back" lets you return to the profile selection.
If a user memory has been loaded or saved, the menu item changes to "Active" (until you
change one of the parameters).

Placement Tips
Keep in mind that a wall-mounted setup enhances bass response, a lineup in one corner
maximizes you! Try not to place the sub near the corner, if possible.
The same applies to your listening position: sit close you will notice an amplification of the bass
response.
Connection Tips:
Je nach vorhandener Audio-Ausstattung stehen unterschiedliche Anschlussmöglichkeiten zur
Verfügung. Versuchen Sie nach Möglichkeit Kabelwege kurz zu halten und Masseschleifen zu
vermeiden.
Option 1: AV / Surround / Preamp with Sub / LFE Out as RCA:
This is a standard scenario for home theater applications.

-12 -
Option 2: AV / Surround / Preamp with Sub / LFE Out as XLR:
This scenario is recommended in the presence of a balanced sub-output and greater distance
between preamp and subwoofer
Option 3:
Integrated amplifier without pre-out:
Connect the speaker outputs of the integrated amplifier to the speaker inputs of the subwoofer.
These are no additional burden on the amplifier.

-13 -
Option 4: Pre / final stage combination with only one pre-out:
In this setup, use 2 Y splitters between preamplifier and power amp to divert the signal for the
sub Or connect the sub to the power amp as in option 3.

Appendix 2: Questions and Answers
Q: The subwoofer has 2 RCA inputs (LFE and R), but my surround pre-amp only has a
subwoofer output. Is it OK to leave an entrance open?
A: Yes, that is not a problem. You can, however, double the pre-amp signal with a Y-splitter and
feed it into both RCA inputs of the subwoofer. The bass reproduction then doubles as a result
Q: My surround pre-amp has both a cinch and XLR output. Which one should I use?
A: If the cable length between the preamplifier and subwoofer is more than 5m, or if you hear
interference from the subwoofer with cinch cable connection, you should use a balanced XLR
cable.
