3) In your listening position, play music of the type previously described.
4) Toggle between 0° and 180° while focusing on the bass output.
The optimal setting of the PHASE switch is where you experience maximum bass output.
5.2 VOLUME ADJUSTMENT
On the rear of the subwoofer you can increase or reduce the volume by turning the VOLUME
control clockwise or counter clockwise.
The volume should be adjusted so that the bass matches the level of your main speakers.
You should be able to appreciate your subwoofer’s contribution to the overall sound, without it
ever being overpowering. Bass must be tight and accurate so that the subwoofer reproduces
the exact amount of bass present in the music/soundtrack; no more, no less. When installing
the DALI SUB E-12F in a surround sound system, we recommend selecting a fixed level on the
subwoofer and adjusting the subwoofer output using the surround (pre-) amplifier’s/receiver’s
setup function.
If bass levels are set too high, distortion will reduce the quality of your listening experience.
Remember that you can boost the bass level by selecting a physical position close to the wall
or even better – in a corner (see chapter “3.0 Positioning”).
5.3 CROSSOVER FREQUENCY ADJUSTMENT
Once you have set the phase and the volume level, you need to adjust the frequency overlap
between the main speakers and the DALI SUB E-12F.
5.3.1 USING LINE INPUT
The crossover frequency adjustment on the subwoofer is only possible when using the LINE INPUT(S).
On the rear of the subwoofer, adjust the CROSSOVER control upwards until you can hear the
bass is even with no drop-outs (Frequency range 40-120 Hz). Smaller speakers typically require
a higher crossover point, whereas larger speakers will accept a lower crossover point. For
example when using your DALI SUB E-12F together with DALI ZENSOR 1, we recommend a
crossover point of approximately 90 Hz.
After having adjusted the crossover frequency you may have to re-adjust the volume to
optimise performance.
5.3.2 USING LFE INPUT
When connecting your DALI SUB E-12F to smaller speakers, e.g. the DALI ZENSOR 1, we
recommend a crossover point of approximately 90 Hz. This must be entered in the menu system
of your (pre-) amplifier. You might need to enter the ‘small’ setting when selecting type of front
speakers in the AV receiver menu.
Connecting larger speakers (typically floor-standing front speakers) will allow you to choose a
lower crossover point, and to define your speakers as ‘large’ in the menu system.
If in doubt about the capacity of your speakers, we recommend setting the crossover point quite
high, defining your speakers as small, and finally reducing the crossover point to the lowest
possible position while maintaining an even bass with no drop-outs.
