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 C-8 D.
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 C-8 D together with DALI SPEKTOR 2, 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 C-8 D to smaller speakers, e.g. the DALI SPEKTOR 2, 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.
5.4 POWER
The POWER switch is the main ON/OFF switch. We recommend switching ‘OFF’ the subwoofer
when it is not to be used for extended periods. When changing connections, always disconnect
the mains voltage from the subwoofer. We recommend that you ALWAYS turn ‘OFF’ the POWER
switch on the rear side of the subwoofer BEFORE turning off the mains switch.
5.5 ON / STAND BY MODE
The subwoofer has a built-in circuit that will power up the amplifier of the subwoofer when an
input signal is detected (given that the POWER is set to ‘ON’ and the POWER MODE switch is
set to ‘AUTO’). When the subwoofer is ‘ON’, the ON/STANDBY LED will light up green. If an input
signal is not detected for approximately 20 minutes, the subwoofer will go into standby mode
and the ON/STANDBY LED will light up red.
