Installing And Adjusting - Dali SUB C-8 D Manuel

WARNING: If the wrong voltage is supplied, there is a serious risk that the electronics of
the subwoofer will suffer permanent damage.
After checking the VOLTAGE, connect the mains cable and move the POWER switch to 'ON'. The
subwoofer is adjusted using the controls on the rear side of the subwoofer (see chapter "10.0
Amplifier Back Plate") in accordance with the following tuning method which will help you
achieve the best results: Play a piece of music you know well, preferably one including rhythmic
bass such as kettle drums, bass guitar etc.
Since the performance is highly dependent on the main speakers, the listening room, the
subwoofer position in the room and your personal preferences, we recommend experimenting
with different settings to achieve the best listening results rather than giving any specific advice
on settings.
NOTE: The position of the subwoofer will significantly affect its contribution to the overall sound
(see chapter "3.0 Positioning"). When you have decided which method of connection you want
to use and you have positioned the subwoofer, you can begin the process of tuning the system.
You are now ready to adjust your DALI SUB C-8 D.
5.1 PHASE SETTING
The PHASE switch of the subwoofer has two settings: 0° or 180°. The phase setting will adjust
the timing between the subwoofer and the main speakers. To set the phase, do the following:
1) Turn up the volume of your subwoofer a little higher than you would normally do.
2) Set the crossover point to maximum (120 Hz).
NOTE: If you have connected the subwoofer via LFE instead of LINE IN you need to set the
crossover point for your subwoofer to maximum in the menu of your surround sound (pre-)
amplifier/receiver.
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 C-8 D 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.
