Dali Oberon On-Wall C + Sound Hub Compact-Light Oak

Easy To Position

The driver materials, crossover design and geometry applied in the OBERON C series has been selected to achieve a wide dispersion pattern. This ensures a well-integrated sound, even when listening at a significant off-axis angle. An added benefit is seriously reduced harmonic distortion and diffractions causing frequency distortion. This is why all DALI speakers are not designed to be toed-in.

Low Latency

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 typically less than 15 mS, and inter-speaker timing is accurate to the single sample period of the broadcast audio data.

Patented SMC

The iron pole piece of the OBERON C woofer magnet is crowned by the DALI patented SMC disk - minimizing the negative effects of the iron. The use of the SMC disk greatly reduces mechanical distortion, which lowers third order distortion. This allows for a longer listening pleasure, a relaxed midrange and a surprising amount of detail for its price class.

Active Speaker

The OBERON C power amplification comprises two 50 Watt peak, closed-loop Class-D power amplifiers chosen specifically for their sound quality and dynamic ability. One amplifier powers the high frequency driver, one powers the bass/mid driver (or twin drivers in the case of the OBERON 7 C).

Oberon 1 C

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. The slim and discreet OBERON ON-WALL C comprises a compact, low profile, rear reflex loaded cabinet fitted with a 5.25” DALI wood fibre cone driver featuring SMC, and a DALI ultra lightweight 29mm soft dome tweeter. The compactness of the OBERON ON-WALL C makes it easy to integrate into any room. To achieve a wide dispersion pattern in the listening area, the driver materials and geometry applied in the OBERON ON-WALL C have been carefully selected. The same principles have been applied in the design of the crossover. As result, you will experience a well-integrated sound, even when listening at a significant off-axis angle. This is important as you are rarely seated directly in front of your loudspeakers when listening to music. An added benefit is seriously reduced harmonic distortion and diffractions causing frequency distortion, as these will always be stronger in an on-axis response. This is also the reason why all DALI speakers are not designed to be toed-in.

Woofer/SMC

The OBERON ON-WALL C builds on a 5.25" bass/midrange driver that features DALI's proprietary fine paper pulp and reinforced wood fibre composite diaphragm materials, which creates a stiff, light-weight and well-behaving structure. In combination with a low-loss surround and spider suspension, this cone reproduces the micro details in the signal - unfiltered and with high accuracy. This is supported by the advanced copper-coated aluminium voice-coil wire and, in particular, our unique SMC (Soft Magnet Compound) magnet technology. By introducing electrically non-conductive elements to the magnet structure, SMC significantly reduces the effect of a variety of distortion-producing mechanisms inherent to moving-coil driver architecture. For example, SMC minimises eddy current effects, increases flux linearity, 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. The membrane terminates in a rubber surround that is chosen for its soft and very flexible properties. This gives the membrane free movement with a very low dampening effect, and leaves the magnet motor to control the membrane movement.

Amplifier

The OBERON ON-WALL C power amplification comprises two 50 Watt-peak, closed-loop Class-D power amplifiers chosen specifically for their sound quality and dynamic ability. One amplifier powers the high frequency driver and one powers the bass/mid driver. The 100dB signal-to-noise ratio of the power amplifiers ensures that even the smallest detail in a quiet musical passage is reproduced with clarity and accuracy. The electronic module mounted on the rear panel of the OBERON ON-WALL C incorporates a wireless receiver element and user setup interface, a DSP equalisation and crossover filter element, and a high efficiency two channel power amplifier with a closely integrated power supply. 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 ON-WALL 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.

Tweeter

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

Cabinet

OBERON ON-WALL C cabinets are constructed from CNC-machined high strength MDF panels and finished with a variety of wood-effect or matt white laminates. The cabinets are engineered for optimum rigidity to minimise panel resonance, with corner fillets. Corner fillets have become increasingly unusual in contemporary speaker cabinet construction but at DALI we believe they play an important role in ensuring rigidity. Internal cabinet damping materials are selected and positioned strategically in order to maximise midrange energy attenuation without degrading bass transient response and bandwidth, as so often the case with reflex loaded speakers. The OBERON ON-WALL C incorporates dual, rear panel reflex ports that are configured to exit in parallel alignment with the wall - incorporating the wall and speaker panel in their operation. The ON-WALL C reflex port is a uniquely innovative solution that plays a significant role in enabling the speaker’s unusually shallow depth dimension. The OBERON ON-WALL C is mounted directly on the wall via rear panel keyhole slots.

Offering HDMI ARC, the SOUND HUB COMPACT is designed for TV audio - switching on and off in sync with the TV. Additionally it enables the use of the TV remote control to adjust volume and mute functions.

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.

Reliable Wireless

The SOUND HUB COMPACT and OBERON C wireless connection is highly stable and introduces next to no packet loss. The robust nature of the wireless connection means that the Sound Hub Compact can be located as much as 10 m apart from the speakers without risk of connection failure or signal interruptions.

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

Inputs

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, but also an ample possibilities to connect music streaming or conventional audio devices. Optical The SOUND HUB COMPACT Optical S/PDIF Input 1 is intended for the connection of CD players or other conventional digital audio sources fitted with a digital optical output. The Optical S/PDIF Input 2 is intended for the connection of TVs fitted with a digital optical output. The auto switch on function of Optical Input 2 is activated by the carrier light in the optical connection, rather than the audio signal, which ensures that the SOUND HUB COMPACT is ready to play TV audio as soon as the TV is switched on. 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. Analogue The SOUND HUB COMPACT analogue line input is intended for the connection of conventional audio sources such as CD players or preamplifiers. Turntables can be connected directly if fitted with a line output, or alternatively, connected via an RIAA phono preamplifier. The analogue input is where audiophile tradition meets the future of wireless active Hi-Fi. The analogue to digital conversion stage following the input generates a high resolution, better than CD, 24 bit/ 96kHz data stream.

Outputs

Sub-out 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 transmitted 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. USB Power 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. IR Signal Receiver 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.

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 variety 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 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 either OBERON C, CALLISTO C or RUBICON C speakers using a proprietary 30 bit wireless protocol derived from the acclaimed DALI SOUND HUB.
