10.0 CONNECTION
Always turn off your amplifier/subwoofer before connecting any cables or altering any connections.
We recommend using special speaker and signal cables. Consult your authorized DALI dealer for
guidance on selection of speaker and signal cables. Use same type cable for all speakers in the
setup (except for the subwoofer). Make sure to connect the correct amplifier output to the correct
speaker – see Figure 5A - C for stereo/surround sound setups. Make sure to connect the positive
amplifier output terminal (red) to the positive speaker input terminal (red) and the negative
amplifier output terminal (black) to the negative speaker input terminal (black), see Figure 6. If just
one speaker is incorrectly connected, the bass might be weak and the overall sound might be diffuse.
Make sure that there are no loose cable strands/ends which potentially can short circuit and damage
the amplifier, see Figure 7. The binding posts accept bare cable ends or 4mm banana plugs.
11.0 LEKTOR SUB
LEKTOR SUB is an active subwoofer with built-in amplifier. On the bottom of the subwoofer there is
a bass reflex port opening. Make sure that the rubber feet will make clearance between the floor
and the bottom of the subwoofer, so that air can flow freely from the bass reflex port. On the rear
side of the subwoofer you will find the amplifier (see Figure 8), which have the following features:
1) Line In L + R, connect your stereo or surround sound amplifier to these inputs using
a RCA cable (sold separately).Adjustment of “Phase”,“Crossover” and “Volume” must
be done on the subwoofer. You might also want to use connection through the
LFE input (see point 2).
2) LFE In, connect your surround sound amplifier to this input using a RCA cable
(sold separately). Adjustment of “Crossover” must be done in the surround
sound amplifier.
3) Auto selector: On: the subwoofer is always on when the power switch (9) is on.
Auto: the subwoofer will power up upon detection of an input signal on the
“Line In” inputs (1 + 2). The subwoofer will power down after approximately 20
minutes with no input signal present on the input connectors. Off: the subwoofer
will be powered down.
4) “Volume” adjustment: Start adjusting the volume of your subwoofer so the bass level
matches the level from the main speakers (with the Crossover (5) knob in the middle
position and Phase switch (6) in the 180° setting). Adjust the level so the contribution
from the subwoofer is firm and precise - but without the bass being too dominant.
If you adjust the volume level too high, your total sound experience may be disturbed
by distortion. Remember that the location of the subwoofer/listening position has a
major effect on the sound pressure you experience.
5) “Crossover” adjustment: adjust the overlap between the subwoofer and the main
speakers by adjusting "Crossover" up and down until you hear the bass is smooth
and without "holes". You may need to readjust the Volume setting (4) slightly
after this adjustment.
6) “Phase” switch, 0˚ or 180˚: adjust subwoofer phase to match the main speakers in
the speaker setup – try both settings to determine which setting sounds best. It might
be necessary to readjust both Volume level (4) and Crossover (5) again.
7) Mains cable connector: check that the voltage written below the mains connector
matches your mains voltage.
8) Fuse compartment: If the subwoofer does not power up, check that the fuse in the
fuse compartment is not blown. If blown, replace the fuse with the same type as
the original. If the fuse blows multiple times, have your subwoofer serviced at
an authorized service facility.
9) “Power” switch: powers the subwoofer on or off. Power off the subwoofer if it
is not used for extended periods. Always power off the subwoofer when
changing connection(s).
10) Heat sink: do not cover! Caution - can be hot!
To connect the subwoofer to your stereo or surround sound system, please consult the
owner’s manual for your stereo/surround sound amplifier to locate a subwoofer output terminal
or a pre-out output terminal. The subwoofer must be connected to the amplifier using a RCA
cable (sold separately).
There are two primary connection options:
A) Connect the subwoofer to a stereo amplifier
Connect the output terminal(s) of the stereo amplifier to the
“Line Input L + R” connectors on the subwoofer amplifier.
B) Connect the subwoofer to a surround sound amplifier
Connect the subwoofer/LFE output terminal on the surround sound
amplifier to “LFE Input” terminal on the subwoofer amplifier.
12.0 TECHNICAL SPECIFICATIONS
In Table 2 (see page 24) you will find most common specifications for our speakers. Please do
remember, that the sound quality from a speaker cannot be judged by technical specifications. To
compare the different speakers, we recommend you to listen to the different speakers in question.
