1. OBERONC and SOUND HUB COMPACT

- The Active Choice

Our world is increasingly one in which wireless technology
is the norm. We’re familiar with the idea and appreciate
the convenience of consumer electronic hardware
that no longer requires a physical connection; printers,
headphones, desktop speakers, telephones, and even
room thermostats for example. Hi-Fi speakers are similarly
undergoing a wireless revolution and DALI has played
a pioneering role with the RUBICON C and CALLISTO
C series. And now, with the new OBERONC series and
SOUND HUB COMPACT wireless audio preamplifier,
DALI has brought wireless active Hi-Fi, that comfortably
outperforms equivalent passive systems, within the reach
of many more music lovers and audiophiles.

At the same time as providing a more cost-eective and
seamlessly integrated wireless Hi-Fi option, the OBERONC
series and SOUND HUB COMPACT are perfectly
configured for contemporary home media installations
where Bluetooth devices and smart TVs are the primary
audio sources.

The OBERONC and SOUND HUB COMPACT major
simultaneously on simplici in installation and operation, and
genuine audiophile sound quali in use. Music lovers and
audiophiles no longer have to choose between incredible
sound quali and convenient integration with their
contemporary Bluetooth and smart TV centred lifesles.
The OBERONC series and SOUND HUB COMPACT
deliver both.

1.1 INTRODUCING THE OBERONC SERIES

The OBERONC series comprises the three, two-way, wireless active speakers derived from the renowned OBERON
passive series and utilising the wireless technology developed for CALLISTO C series. The compact, stand or shelf­mount OBERON1C, the floor standing OBERON7C, and the compact, low profile wall-mount OBERON ON-WALL C:
the OBERONC series is ideally suited for use with the new SOUND HUB COMPACT wireless audio preamplifier
however, it is also compatible with the existing SOUND HUB.

OBERON1C

The OBERON1C is the compact speaker of the series.

Sporting a 29mm ultra-lightweight so dome tweeter

and a 5.25” wood fibre cone SMC bass/midrange driver,

its rear reflex loaded cabinet oers an optimal balance

between internal volume for bass performance and

compact dimensions for small rooms. The OBERON1C

can be used with the DALI CONNECT Stand E-600,

installed within furniture units or on shelves, or wall

mounted directly via rear panel keyhole slots.

OBERON7C

The slender proportioned, floor-standing and rear reflex
loaded OBERON7C sports twin, 7” DALI wood fibre cone
SMC bass/mid drivers, and the same DALI ultra-lightweight
29mm so dome tweeter as the OBERON1C. Despite its
size, the OBERON7C is a subtle performer and impresses
with its abili to render any sle of music naturally and
lifelike, even at low volume levels. The OBERON7C
incorporates an integral die-cast plinth fied with
aachment points for floor-spikes or compliant feet.

DALI A/S www.dali-speakers.comDALI OBERON C 3

All three OBERONC speakers incorporate

wireless interface, digital signal processing

(DSP) and Class D power amplification

electronics in a module located on their rear

panels. The two-channel amplification in each

OBERON model provides 50 Was each

for the bass/mid and high frequency drivers.

Crossover functions within the OBERONC

electronics are implemented through DSP

running at 24 bit/96 kHz resolution.

OBERON ON-WALL C

The slim and discreet OBERON ON-WALL C comprises
a compact, low profile, rear reflex loaded cabinet fied
with a 5.25” DALI wood fibre cone SMC bass/mid driver,
and a DALI ultra lightweight 29mm so dome tweeter. The
OBERON ON-WALL C was designed with TV audio very
much in mind and despite its compact dimensions, the
combination of DALI technologies employed endow it with
performance comparable to significantly larger speakers.
The OBERON ON-WALL C is designed specifically for
direct wall mounting via rear panel keyhole slots. Portrait
and landscape orientations are both accommodated.

NOTE

OBERONC series speakers are additionally compatible with
the DALI SOUND HUB wireless audio preamplifier originally
introduced with CALLISTO C series. In addition to providing
Bluetooth and a varie of wired audio inputs, the SOUND
HUB is equipped with facilities for future expansion and
upgrade. For example, with its optional NPM-1 BluOS module
installed, the SOUND HUB can provide MQA certified high
resolution music streaming and multiroom functionali, as
well as supporting Spoti Connect.

1.2 INTRODUCING THE SOUND HUB COMPACT

Designed specifically with seamless TV integration and
Bluetooth audio in mind, the SOUND HUB COMPACT
wireless audio preamplifier combines all the functions
and interface facilities needed to play the central role in
a complete wireless active Hi-Fi system. It can handle a
varie of wired digital and analogue sources, including
HDMI ARC, and also pair with Bluetooth audio devices such
as smartphones, tablets, laptop and desktop computers to
enable entirely wireless audio playback. The SOUND HUB
COMPACT can be installed on a table, shelf or furniture unit
or be direct wall-mounted using its keyhole slot features.

The SOUND HUB COMPACT is controlled via its supplied
infrared remote control in combination with its top panel
input selection and volume indicators. In use, the SOUND
HUB COMPACT is intuitive and immediate. Its user
interface is designed to place as few operational hurdles

as possible between the user and their favourite audio
source. For example, when connected to a TV via HDMI
the TV remote control is all that’s needed for volume and
standby control, and with Bluetooth audio, the source
playback app eectively takes control – including volume
synchronisation. The system will even automatically switch
on when a previously paired Bluetooth device is connected
and playback initiated. There’s no complex control app to
learn, just automatic input switching and intuitive source
based volume control.

The SOUND HUB COMPACT transmits to OBERONC
speakers using a proprietary 30 bit wireless protocol
derived from the acclaimed DALI SOUND HUB. Audio
transmission latency from input to speaker is pically less
than 15mS, and inter-speaker timing is accurate to the
single sample period of the broadcast audio data.

NOTE

The SOUND HUB COMPACT
is additionally compatible
with the RUBICON C and
CALLISTO C series of active
wireless speakers.

2. Choosing and Using OBERONC

The three OBERONC wireless active speaker models are each designed to suit and appeal to
dierent applications and users.

OBERON1C

The OBERON1C is intended for smaller rooms where space is a precious commodi and
volume levels are relatively modest. Music lovers and audiophiles who prefer the sle and sound
of stand-mounted speakers will be drawn towards the OBERON1C. Listening to music, perhaps
from CD, internet radio, or a turntable and precious record collection, is likely to be their
priori over TV audio – although if the OBERON1C speakers are located appropriately, one on
either side of the screen, TV audio may become increasingly of interest.

OBERON7C

The OBERON7C is intended for
more expansive homes where music
has space to breathe and can be
played at higher volume levels. It will
suit more ambitious music lovers and
audiophiles, keen to make a grander
statement with their audio system.
With more space and speaker
positioning options available in larger
rooms, it is perhaps more likely that
OBERON7C speakers will be located
on either side of a screen and used
for TV audio, but still, music playback
from CD or streaming services will
probably be their primary role.

DALI A/S www.dali-speakers.comDALI OBERON C 6

OBERON ON-WALL C

The OBERON ON-WALL C is intended to find a role in
any room, large or small, that includes a wall mounted TV
with space for a speaker on either side. In contrast to
the OBERON1C and OBERON7C, the OBERON ON­WALL C is designed specifically to suit wall-mounted TV
audio applications, where it will almost certainly produce
more satising results than a TV soundbar. Having said
that however, the OBERON ON-WALL C is equally adept
at reproducing all audio formats, and while it is most likely
to suit those for whom TV audio is a priori, its inherent
DALI quali will perhaps increasingly entice simple music
reproduction.

OBERONC FINISHES

OBERONC speakers are available in four high quali
laminate cabinet finishes and are supplied with a contrasting
grey fabric grille aached with conventional grille pegs. The
use of grilles is entirely optional.

The four OBERONC laminate finishes: ma white, light
oak, dark walnut and black ash, were chosen specifically to
provide options that cover the full range of colour tones
and themes found most commonly in homes throughout
the world. At the same time, the laminate tones work with
the grille fabric and aesthetic detail of the speakers to
reinforce the traditional DALI values of sensitive and slish
Danish design.



DALI is driven by the philosophy that beer music in the
home is a force for good, and the technologies that enable
the OBERONC series and SOUND HUB COMPACT to
perform to such an exceptional level are really no more
than means to that end.

3.1 OBERONC

The temptation for many Hi-Fi manufacturers when
developing active speakers is to believe that active
amplification and digital signal processing can compensate
for the use of less technologically sophisticated, and
perhaps less expensive, drivers and electro-acoustic
engineering. At DALI we know that this simply isn’t true, and
in fact, in some technical respects such as the distortion
eects that can arise from the driver magnet and voice-

NOTE

THE ACTIVE DIFFERENCE

The dierence between active and passive speakers is not
simply that active speakers require a mains power supply.
There is a fundamental advance in the ‘architecture’ of an
active speaker that should, in theory, result in significant
performance advantages over a similar passive design. In
a passive speaker, a single power amplifier output channel
is connected to a passive crossover network that divides
the signal between the two (or sometimes more) drivers.
Because the crossover network is positioned downstream
of the power amplifier, the inductive and capacitive
components that create its filters need to be of high values
and power ratings, and that means they tend to be both
relatively “lossy” and to have their own sonic signature.
Passive crossover networks are also aected by the
impedance of the downstream drivers, and if that changes,
as voice-coil temperature rises for example, the frequency
response of the crossover filters will also change.

coil system, active amplification makes greater demands
on performance than passive amplification. Furthermore,
with the drivers eectively connected directly, while there
is minimal loss from passive crossover components, the
amplifiers are required to drive more dynamic loads, so
care has to be taken to ensure the amplifiers and drivers
are matched appropriately.

So, with the OBERONC series, rather than seeing active
amplification and DSP ‘horsepower’ as an opportuni to
simpli or down-spec the drivers, we commied early in
the development process to use the same technologically
advanced units that perform so spectacularly in the passive
OBERON series. Matching these exceptional drivers with
active amplification and DSP filter technology made it
possible to create in the OBERONC speakers a level of
performance significantly higher than their passive speaker
counterparts.

unknown in active speakers. Such a steep slope would be all
but impossible to implement in a passive filter.

In the paragraph above we’ve described active crossovers
in the analogue domain but in the OBERONC series the
concept of an active crossover has been taken one step
further by positioning it even before the digital to analogue
conversion stage. The crossover is implemented entirely
within the digital signal processing DSP, so now there’s not
even any capacitors or transistors involved in creating the
filter slopes. Everything is done in the digital domain through
immensely fast binary processing.

In an active speaker, each driver is connected directly to its
own dedicated power amplifier, with the crossover dividing
the signal located before the power amplifier inputs. This
immediately means that, firstly, the amplifiers have much
improved control over the drivers, and secondly that driver
impedance changes don’t aect frequency response. A
further advantage is that if one amplifier reaches its power
limits and clips the signal, the other amplifier (or amplifiers)
will not be aected. With the crossover network now
working on a line-level, rather than a power-level, signal,
its filters can be generated through the use of low value
and very low loss capacitors combined with high precision
transistors. But active crossovers don’t only achieve a
level of precision and consistency that passive crossovers
can’t ever hope to match, they can also be designed to have
much steeper filter slopes. For example, a steep, fourth
order filter with 24dB/octave slopes is problematical in
a passive crossover – the likely component losses and
sensitivi to downstream driver impedance are just about
at the limit of feasibili. A fourth order active filter however
is in principle no less feasible to implement than a first order
one. Even eighth order (48dB/octave) filter slopes are not

BASS/MID DRIVER

OBERONC bass/mid drivers feature our proprietary paper
pulp and wood fibre composite diaphragm materials, advanced
copper-coated aluminium voice-coil wire and, in particular, our

unique SMC (So Magnet Compound) magnet technology. By

introducing electrically non-conductive elements to the magnet

structure, SMC significantly reduces the eect of a varie

of distortion-producing mechanisms inherent to moving-coil

driver architecture. For example, SMC minimises eddy current

eects, increases flux lineari, reduces magnetic hysteresis and

minimises the variation of voice-coil inductance with position.

Taken together, these benefits make SMC equipped drivers

particularly suited to active amplification.

HIGH FREQUENCY DRIVER

The OBERONC high frequency driver is a damped textile
dome tweeter featuring an unusually light diaphragm and a
larger than pical, 29mm diaphragm and voice-coil. The light
diaphragm means that the upper frequency response of the
driver is unusually extended before its mass limited roll-o,
while the large diameter diaphragm and voice-coil increases
sensitivi and power handling, reduces distortion, and
enables the driver to operate to lower frequencies than is the
case with smaller tweeters, which helps provide more latitude
in crossover design. Further increasing power handling,
and significantly reducing signal compression as the voice­coil temperature rises with increased volume, the driver is
equipped with ferro-fluid in its voice-coil gap.

CABINET CONSTRUCTION

OBERONC cabinets are constructed from CNC-

machined high strength MDF panels and finished with

a varie of wood-eect or ma white laminates. The

cabinets are engineered for optimum rigidi to minimise

panel resonance, with corner fillets and, in the case

of the larger OBERON7C, strategic internal cross-

bracing. Corner fillets have become increasingly unusual

in contemporary speaker cabinet construction but at

DALI we believe they play an important role in ensuring

rigidi. OBERONC internal cabinet damping materials

are selected and positioned strategically in order to

maximise midrange energy aenuation without degrading

bass transient response and bandwidth, as so oen the

case with reflex loaded speakers.

The OBERON1C and OBERON7C are fied with

unusually large diameter rear panel dual-flare reflex

ports that are engineered to minimise port turbulence,

distortion and compression, while also factoring-in the

potential proximi of the rear wall. Flaring on the port

entrance, as well as on the exit, delays the onset of

airflow turbulence as volume level rises, and helps ensure

that bass performance remains consistent at all volume

levels. Rear-mounting the reflex ports has the great

advantage of directing any midrange energy emied from

inside the cabinet away from the listening position.

WIRELESS FUNCTIONS

The OBERONC wireless receiver module acquires the
digital wireless stream transmied from the SOUND HUB
COMPACT or SOUND HUB and, depending on the channel
role assigned to the speaker when it is set up, either the
le or right channel data is discarded. The remaining
channel data is then passed in unchanged at 24 bit/96 kHz
resolution to the DSP based equalisation and crossover
filter electronics.

distortion limits. It’s partly thanks to dynamic profiling that
OBERONC speakers remain subjectively so consistent at
all volume levels.

Following equalisation, the crossover filter module divides
the signal appropriately for the bass/mid and high frequency
drivers through a pair of digital filters: a low-pass filter
feeding the bass/mid driver and a high-pass filter feeding the
high frequency driver. The filter slopes have a profile that
combines a relatively slow roll-o with benign phase change
through their pass-band regions.

EQUALISATION AND CROSSOVER
FILTER FUNCTIONS

The OBERONC equalisation and crossover filter elements
play two roles. Firstly, through gentle modification of
frequency response, equalisation helps ensure that the
speaker produces the appropriate, neutrally balanced
overall response in the listening room. Not too bright or too
bass heavy, and with the perfect midrange level. A specific
custom DSP equalisation profile was developed for each
OBERONC model in order to create a tonal balance that
suits its cabinet size and likely installation environment.
Only active DSP technology can enable the degrees of
freedom that makes such equalisation feasible. For example,
the boundary eect on the frequency response of a wall
mounted speaker such as the OBERON ON-WALL C is all
but impossible to correct with passive equalisation, but such
correction is easily within the scope of active equalisation.
As a result of active boundary correction, the OBERON
ON-WALL C displays none of the subjective tonali oen
associated with on-wall locations. It has more of the open,
unconstrained character of a free-standing speaker.

Secondly, the OBERONC equalisation stage analyses the
incoming signal and, depending on its low frequency content
and the speaker volume level, applies subtle dynamic
profiling to ensure that the speaker’s bass/mid drivers
are not required to work outside their comfortable, low

The opportuni to apply both equalisation and crossover
filtering entirely in the digital domain is one of the enormous
advantages that digital active speakers have over their
traditional analogue passive cousins. As we described
earlier however, such theoretical advantages can only result
in improved subjecting performance if, as is undoubtedly the
case with OBERONC, the fundamental speaker electro­acoustics are up to the task.

POWER AMPLIFICATION

The OBERONC power amplification comprises two 50
Wa peak, closed loop Class-D power amplifiers chosen
specifically for their sound quali and dynamic abili. One
amplifier powers the high frequency driver, one powers
the bass/mid driver (or twin drivers in the case of the
OBERON7C). The 100dB signal-to-noise ratio of the power
amplifiers ensures that even the smallest detail in a quiet
musical passage is reproduced with clari and accuracy.
Powering the amplifier is a custom designed, 65W(rms),
very low noise switched mode supply that is able dynamically
to share resources between the two amplifier channels
in response to demand. The OBERONC is, as a result,
unusually frugal in terms of power consumption, yet gives
nothing away in terms of dynamic punch when the music
demands it.

DALI A/S www.dali-speakers.comDALI OBERON C 11

3.2 SOUND HUB COMPACT

As its name suggests, the SOUND HUB COMPACT
plays the central role in an active wireless Hi-Fi system
comprising a stereo pair of OBERONC speakers. Designed
primarily with Bluetooth audio and HDMI connections in
mind, The SOUND HUB COMPACT receives wired or
Bluetooth audio sources and transmits them wirelessly to
the speakers. The SOUND HUB COMPACT was designed
specifically to achieve compact dimensions and is slim
enough that it can even be located out-of-sight behind a
wall-mounted TV.

NOTE

The SOUND HUB COMPACT is
additionally compatible with the
RUBICON C and CALLISTO C series
of active wireless speakers.

WIRELESS TECHNOLOGY

The SOUND HUB COMPACT wireless connection
protocol is a proprietary 30 bit digital stream broadcast
over the 5.2 GHz or the 5.8 GHz band. The optimal band
option is selected automatically depending on the local
radio signal environment. The 30 bit protocol transmits
uncompressed I2S audio at 24 bit/96 kHz resolution
and utilises the remaining six bits for feed-forward error
correction, volume control, speaker identification and for
other miscellaneous functional requirements.

ZERO LOSS

The need for volume control data to be transmied to the
speakers results from the implementation in the SOUND
HUB COMPACT and OBERONC of DALI Zero Loss
volume control technology. Zero Loss ensures that volume
adjustment does not result in data loss through truncation
of the digital word length. By placing speaker volume
control at the end of the digital signal chain, directly before
the digital to analogue conversion stage, full 24 bit digital
resolution is retained at all volume levels.

RELIABLE WIRELESS

Thanks partly to utilising a relatively un-congested radio
band, and partly to the use of a protocol specifically
designed for audio data, the SOUND HUB COMPACT
and OBERONC wireless connection is highly stable and
introduces next to no packet loss. Feed-forward error
correction is employed however to eliminate the results of
packet loss should it occur. The sub 15mS input to speaker
latency of the system means also that the SOUND HUB
COMPACT and OBERONC system can be used in audio­visual systems with no resulting loss of lip-sync.

The robust nature of the SOUND HUB COMPACT and
OBERONC wireless connection means they can be located
as much as 10m apart without risk of connection failure or
temporary signal interruptions.

ANALOGUE LEGACY

The SOUND HUB COMPACT is almost entirely digital in its
internal signal path and processing, however it incorporates
a high quali analogue input designed for legacy audiophile
sources such as CD players, preamplifiers and turntables.
The analogue to digital conversion stage following the input
generates a high resolution, beer than CD, 24 bit/ 96kHz
data stream.

INPUTS AND CONNECTIONS

With five discrete audio inputs available, the SOUND HUB
COMPACT can connect to almost any audio device. For
example, there are no less than four ways to connect a TV
and transmit its audio to OBERONC speakers, but there
are also ample possibilities to connect music streaming or
conventional audio devices.

BLUETOOTH

The SOUND HUB COMPACT Bluetooth input features
AAC and aptX HD high performance codecs and enables
smartphones, tablets, laptop or desktop computers, or
any other Bluetooth audio source easily and quickly to play
either locally stored or streamed music. Even Bluetooth
equipped TVs can be connected to create a completely
wireless TV audio solution.

DALI A/S www.dali-speakers.comDALI OBERON C 12

HDMI ARC

The SOUND HUB COMPACT HDMI ARC is designed to
play TV audio. It additionally supports CEC to enable the
use of the TV remote control to adjust volume and mute
functions, as well as to switch the SOUND HUB COMPACT
on and o in sync with the TV.

AUTO-SWITCHING

The SOUND HUB COMPACT has optional auto signal
detect on all inputs. With auto signal detect switched on,
instigating playback on the source will trigger the SOUND
HUB COMPACT automatically to switch on and select the
appropriate input. If there is no audio for 20 minutes, the
SOUND HUB COMPACT (and OBERONC speakers) will
automatically switch to standby mode and save energy.

FURTHER CONNECTIONS

The SOUND HUB COMPACT provides a volume controlled,
line-level analogue subwoofer output that switches on
automatically when a subwoofer connection is detected.
The subwoofer output is low-pass filtered at 100Hz to
match the frequency characteristics of the main speakers.
When a subwoofer is in use, the audio transmied to the
main speakers is high-pass filtered to reduce its energy
content below 80Hz and preserve power handling in the
main speaker frequency band.

The SOUND HUB COMPACT incorporates a USB-A
socket that’s primarily intended for service and diagnostic
use. The USB socket can however also be used to charge
a mobile device or to power a media streaming device such
as an Amazon Echo or Google ChromeCast Audio, the
output from which can then be routed to a SOUND HUB
COMPACT input and potentially introduce a voice control
element to the system.

The SOUND HUB COMPACT includes a wired IR Signal
Receiver accessory that enables it to be located out of
line-of-sight of its remote control handset. The IR Signal
Receiver is optionally connected to a SOUND HUB
COMPACT rear panel socket. Connecting the IR Signal
Receiver disables the SOUND HUB COMPACT integrated
IR receiver.

4. OBERONC and

SOUND HUB COMPACT

- The Active Choice

The OBERONC series demonstrates that the theoretical
advantages of active speakers can be truly realised, and
plainly heard, and proves that genuine Hi-Fi speakers can be
easily integrated in contemporary lifesles needs and media
systems. And the SOUND HUB COMPACT demonstrates
that versatili of use in the modern world of both streamed
and conventional audio need not mean any compromise of
functionali or sound quali.

The OBERONC and SOUND HUB COMPACT represents a
new era of revolution in the DALI story. The traditional DALI
values of easy accessibili, simple operation and class-
beating sound quali have found their way into a genuinely
high-performance digital, active wireless Hi-Fi system.
