Dali Oberon 1 C

Description

Dali Oberon 1 C  :  Active Bookshelf Speaker

Dali Oberon 1 C Active Speaker is the compact model of the series sporting a 29mm ultra-lightweight soft dome tweeter, 5.2″ wood fibre cone, SMC bass/midrange driver and rear reflex loaded cabinet for an optimal balance between internal bass performance and compact dimensions for small rooms.

Oberon 1C can be used with the Dali Connect E-600 Stand, installed within furniture units, on shelves or wall mounted directly via rear panel keyhole slots.

Oberon C Active Series

Following on from the success of the pioneering Rubicon C and Callisto C wireless series, the new Oberon C series brings you wireless active Hi-Fi that comfortably outperforms equivalent passive systems.

The cost-effective and seamlessly integrated wireless Hi-Fi speaker is perfectly configured for contemporary home media installations where Bluetooth devices and smart TVs are the primary audio sources. Music lovers and audiophiles no longer have to choose between incredible sound quality and convenient integration with their contemporary Bluetooth and smart TV centred lifestyles.

Oberon C1 Overview

Dali Oberon 1C is a two-way wireless active speaker derived from the renowned Oberon passive series and utilising the wireless technology developed for Callisto C series. The compact, standmount Oberon 1C is ideally suited for use with the new Sound Hub Compact wireless audio preamplifier and is also compatible with the existing Sound Hub.

All three Oberon C speakers incorporate wireless interface, digital signal processing (DSP) and Class D power amplification electronics in a module located on the rear panels. The two-channel amplification in each Oberon model provides 50W 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.

Sound Hub Compact or Sound Hub

This speaker comes with the option of Sound Hub Compact (which is HDMI, Bluetooth, Optical, Analogue, Sub out) or Sound Hub (which has multiple digital inputs, analogue inputs and a BLUOS streaming module). SHC is aimed for those wanting to use it with their TVs whereas the SH is more suitable for audio enthusiasts.

For Smaller Rooms

Dali Oberon 1C is intended for smaller rooms where space is a precious commodity and volume levels are relatively modest. Music lovers and audiophiles who prefer the style and sound of stand-mounted speakers will be drawn towards the Oberon 1C.

Listening to music, perhaps from CD, internet radio or a turntable and precious record collection is likely to be the priority over TV audio – although if the Oberon 1C speakers are located appropriately, one on either side of the screen, TV audio may become increasingly of interest.

Active Amplification

With the Oberon C series, rather than seeing active amplification and DSP ‘horsepower’ as an opportunity to simplify or down-spec the drivers, Dali committed 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 a level of performance significantly higher than their passive speaker counterparts.

Based upon the well renowned and award-winning Oberon series of passive loudspeakers, Oberon C uses both known and new technologies from Dali’s own Callisto C and Rubicon C systems. The rear panel mounted Oberon C electronic module 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

SMC Bass/Mid Driver

Dali Oberon C bass/mid drivers feature proprietary paper pulp and wood fibre composite diaphragm materials, advanced copper-coated aluminium voicecoil wire and 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.

High Frequency Driver

Oberon C high frequency driver is a damped textile dome tweeter featuring an unusually light diaphragm and a larger than typical 29mm diaphragm and voicecoil. The light diaphragm means that the upper frequency response of the driver is unusually extended before its mass limited roll-off while the large diameter diaphragm and voice coil increases sensitivity 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 variety of wood-effect or matt white laminates. The cabinets are engineered for optimum rigidity to minimise panel resonance with corner fillets which have become increasingly unusual in contemporary speaker cabinet construction. Oberon C internal cabinet damping materials are selected and positioned strategically to maximise midrange energy attenuation without degrading bass transient response and bandwidth as is so often the case with reflex loaded speakers.

Oberon 1 C is fitted 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 proximity 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 emitted from inside the cabinet away from the listening position.

Wireless Functions

Dali Oberon C wireless receiver module acquires the digital wireless stream transmitted 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 left 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.

EQ Function

Dali Oberon C EQ and crossover filter elements gently modify frequency response to help ensure the speaker produces the appropriate, neutrally balanced overall response in the listening room. It also analyses the incoming signal and, depending on its low frequency content and 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 distortion limits making performance consistent at all volume levels.

Crossover Filters

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 opportunity 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.

Power Amplification

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.

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. Powering the amplifier is a custom designed, 65W(rms), very low noise switched mode supply that dynamically shares resources between the two amplifier channels in response to demand.

Finish Options

Oberon C speakers come in four high quality laminate cabinet finishes (matt white, light oak, dark walnut and black ash) and are supplied with a contrasting grey fabric grille attached with conventional grille pegs. The use of grilles is entirely optional. The finishes were chosen specifically to provide options that cover the full range of colour tones and themes found most commonly in homes throughout the world.
