UNPACKING
Be careful not to damage the contents when you unpack the parts. Depending on which DALI OBERON model you have bought, different accessories come with the loudspeaker. Check that all parts are contained in the cardboard box (see Table 1). Keep the packaging materials should your speaker need to be relocated or serviced.
GRILLES
The speakers are delivered with the grille fronts already mounted when you
unpack them.
Remove transport protection from OBERON 1, 3, 5, and 7 (See Figure 3) before
use. If you wish to remove the grille front, loosen it by gradually tugging at
the plungers that hold it in place. It is important that all plunges are
equally loosened before removing the front. Otherwise, the grille may be
damaged.
POSITIONING
To achieve the best results, the loudspeaker setup should be symmetrical
around your favorite listening position (see Figure 1A – C). We recommend that
you experiment with the position of your loudspeakers – the sound quality will
change depending on the loudspeaker position. Objects positioned between the
speaker and the listening position might negatively affect sound quality.
The speakers are designed to meet our wide dispersion principle, so they
should NOT be angled towards the listening position, but be positioned
parallel with the rear wall, see Figure 2. By parallel positioning, the
distortion in the main listening area will be lowered and the room integration
will be improved. The wide dispersion principle will ensure that sound is
spread evenly within a large area in the listening room
DALI OBERON 5 & 7
Both speakers are designed as floor-standing speakers and they should ideally
be positioned a minimum of 20 cm (8”) from the rear wall.
They both can be used with spikes or rubber bumpers under the speakers (see
Figure 4D/E). Be careful not to over-tighten the spike locking nuts.
Spikes or rubber bumpers can improve the sound quality. You can try both to
hear what gives the best sound quality in your setup. Please be aware, that
spikes may damage the floor if it is not protected by e.g. coins under the
spikes.
DALI OBERON 1 & 3
The speaker can be positioned on a stand/shelf or for OBERON 1 hung on a wall
using the integrated wall bracket. If positioned on a stand or shelf, the
enclosed rubber bumpers can be mounted under the speaker for stable and
vibration-free positioning (see Figure 4A).
If hanging OBERON 1 on a wall, mount the bumpers on the rear edges of the
speakers (see Figure 4B). The speaker is hung on a wall using one screw
mounted on the wall. The screw must fit the wall bracket on the rear side of
the speaker (see Figure 4C).
Both speakers should ideally be positioned so that the height of the tweeter
is approximately at ear height when seated in your favorite listening
position.
DALI OBERON ON-WALL
DALI OBERON ON-WALL is optimized for wall-mounting (see Figure 7), and should
ideally be positioned so that the height of the tweeter is approximately at
ear height when seated in your favorite listening position. There should be at
least 10 cm (4”) to any surface underneath the speaker.
DALI OBERON VOKAL
OBERON VOKAL is the dedicated center channel and has been specially designed
to be positioned close to the large surface of the TV screen. You can place it
above or below the screen, on a stand, or on a shelf. We recommend fitting the
enclosed bumpers to ensure a stable, vibration-free setup (see Figure 4F).
CONNECTION
Correct, tight connections to your amplifier are extremely important for your
listening experience.
Always use cables of the same type and length for left and right channels. We
recommend using special speaker cables from DALI, available from your dealer.
Connection in the correct phase is a detail that is often ignored. The red (+)
terminal of the amplifier must be connected to the red (+) terminal of the
loudspeaker. The black (-) terminal of the amplifier must be connected to the
black (-) terminal of the loudspeaker (see figure 5). Even a single
loudspeaker connected out-of-phase in a stereo or surround installation will
make the bass weaker and the stereo image unfocused.
For the optimal listening experience, the right loudspeaker (as seen from the
listening position) must be connected to the amplifier output terminals marked
“R” or “Right”. The left loudspeaker must be connected to the amplifier output
terminals marked “L” or “Left”.
NOTE: Before connecting cables or changing any connections, ALWAYS turn
off your amplifier.
NOTE: Make sure that the bare conductors are tightly gripped by the
terminals with no loose wires which could cause a short circuit and damage the
amplifier (see Figure 6).
NOTE: If you are using DALI OBERON in a surround system, follow the
instructions included with your surround amplifier.
RUNNING-IN
Like any mechanical system, a loudspeaker requires a “running-in” period to
perform at its best.
You will experience a gradual increase in sound quality during the first
period of use. The break-in period will vary depending on use and playback
volume. You should expect up to 100 hours of playback until maximum
performance is reached. Unlike other mechanical systems, the lifespan of a
loudspeaker is increased by normal, regular playback of music.
CLEANING & MAINTENANCE
Clean the cabinets with a soft, dry cloth. If the cabinets are dirty, wipe with a soft cloth dipped in an all-purpose cleaner and then well wrung out. Be very careful when wiping the speaker cones, as they are very fragile. Front grilles can be cleaned with a clothes brush and wiped with a well-wrung, lint- free cloth and mild all-purpose cleaner.
AVOID DIRECT SUNLIGHT:
The surfaces of the speakers may fade or become discolored over time when
exposed to direct sunlight. Therefore avoid positioning the speakers in direct
sunlight.
DISPOSAL
If you want to dispose of this product, do not mix it with general household waste. There is a separate collection system for used electronic products in accordance with legislation that requires proper treatment, recovery, and recycling. Private households in the EU member states, Switzerland, Liechtenstein, and Norway may return their used electronic products free of charge to designated collection facilities or to a retailer (if you purchase a similar new one). If you reside in the countries not mentioned above, please contact your local authorities for the correct method of disposal. By following this process, you will ensure that your disposed product undergoes the necessary treatment, recovery, and recycling and thus prevent potential negative effects on the environment and human health
POWER AND ACOUSTIC PRESSURE
How loud a speaker is able to play and still sound good is completely
dependent on the signal it has to reproduce. So, in practice, it is not
possible to define an unequivocal level for use in comparing different
speakers.
Lots of pure, undistorted output from a large amplifier is better than a
distorted signal from a small amplifier stretched beyond its capacity. The
signal from a distorting (clipping) amplifier contains much more high-
frequency information than an undistorted signal and therefore puts a heavy
strain on the tweeter. Consequently, speakers are often damaged by small
amplifiers, having to work too hard – and very rarely by large amplifiers,
which are practically running idle.
It is worth noting that turning tone controls above the neutral setting
significantly burdens both speakers and amplifiers. On a good sound system,
tone controls should only be used to compensate for poor recordings and not to
permanently compensate for weaknesses elsewhere in the system. DALI recommends
the tone controls generally be set to the neutral position, and to achieve
your desired sound image through the correct positioning of the speakers.
Ensuring that you keep the volume low enough for the sound to remain clear and
undistorted will minimize the strain on both speakers and amplifiers.
All DALI loudspeakers are designed with linear impedance for an optimal amplifier load. The result is a significantly more open and detailed sonic image.
THE LISTENING ROOM
Every room has its own distinctive acoustics, which influences the way we
experience sound from a speaker. The sound you hear consists of direct sound
from the speakers and reflected sound from the floor, ceiling, and walls. The
latter will affect how you experience the sound.
As a basic rule, try to avoid large, hard and reflective areas in the
immediate vicinity of your loudspeakers as it will typically cause strong
reflections, which might disturb the precision and spatial effect of the sound
reproduction. Reflection might be suppressed by positioning e.g. a plant
between the speaker and the reflecting surface. Soft items such as carpets,
curtains, etc. |
might help if the sound is too bright. Both the amount and quality of the deep
bass depend on the size and shape of the room, and the position of the
speakers. Positioning the speakers near a side or back wall will accentuate
the bass.
A corner location will accentuate it even more, but will also increase the
reflections.
TECHNICAL SPECIFICATIONS
In Table 2 you will find the most common specifications for our speakers. Please have in mind that there are countless methods for measuring speakers. However, none of them tell you anything useful about how a speaker really sounds. Only your ears can decide whether one speaker sounds better than another. Like all our speakers, the DALI OBERON series is designed to reproduce music as honestly as possible.
Enjoy your new DALI OBERON!
