Technologies and Components

Cutting edge audio high-tech.
By dividing the integrated amplifier into separate pre- and control amplifiers, we have created the Aavik P-series and the Aavik C-series. This has made it possible to reduce the noise floor, to an even lower level, refine the signal, and increase the power resources. Furthermore, this division has created space for new technologies, which have further contributed to a even larger sound stage with an extremely quite background.

Scandinavian design with an international twist

The Aavik design is Scandinavian understatement and expresses simplicity and minimalism featuring only a few buttons for logical operation. The multifunctional main knob allows to navigate and control the various functions. We have boosted the self-confidence with a huge red display, which makes it easy to read all details of the selected operational settings.

A cabinet with excellent sonic qualities

The cabinet design represents a Aavik characteristic. The testing of new circuits and electronic components is often done without the enclosing cabinet. The disturbing sonic influence, which emanates from the material the cabinet is made of – mostly aluminium – results from its mechanical resonance. To eliminate this sonic distortion, the challenge was to minimize the use of aluminium in the cabinet to the absolute minimum that is unavoidable to ensure sufficient cooling. We began testing various materials and designed an innovative natural-based composite material, which reduces the mechanical influence, particularly the hysteresis. The sonic result is distinctly audible and reflects a further prominent cornerstone in Aavik’s quest for the ultimate music experience.

Shaping

Built like an instrument.
Our untiring endeavour to unlock further untapped sonic potentials to advance the quality of the listener’s musical experience, prompted us to look into the design and construction of musical instruments – both in terms of shape, as well as choice of material. A combination of the natural-based composite material, the contours and the ratio of the sizes can impact and define the tone. Too much damping kills the dynamics, whereas metallic resonances generate a bright and peaky sound – Aavik’s engineered enclosure offers the best of both worlds: an authentic sound that is warm, harmonious, and powerful, yet, at the same time, so crisp and refined that it highlights every single detail in the music.

Separates

No compromise.
The decision to build separate units reflects Aavik’s intent of space management without any sonic compromise. Allowing sufficient space for each segment, has also influenced the integration of a high-grade power supply with a huge capacity and paved the way for an effective cooling design.

By separating the individual units and redesigning them in a totally isolated fashion, the Aavik series has gained in dynamic momentum and a more expansive sound.

Separate power supply

The Aavik series is designed to ensure massive power resources with ultra-low noise. When more power is needed, the operating frequency increases, which, in turn, has the advantage that the power density also increases, thus allowing higher peak power when required by the music. The noise floor in the raw power supply is extremely low and is even further lowered by the ultra-low noise regulators supplying the different parts of the circuit. The noise of these regulators is measured in a few microvolts respectively nanovolts, which is significantly lower than the noise level of conventional regulators.

Analog crossover

The Aavik analog crossover secures a precise timing in the delivery of sound signals to the receiving components. This is essential to avoid a harsh and compressed sound. The Aavik crossover has been designed to either very precisely control a subwoofer or with the integrated low pass and high pass filter to control a 2.1 home theater system. Alternatively, Aavik’s analog crossover can function as analog room correction control.

Excellent and absolutely precise subwoofer control
Since the crossover is analog, there is no latency. The timing of the signal transfer to both the speakers and the subwoofer is absolutely precise. This results in an utmost pristine and authentic sound. Other conventional crossovers, such as DSP transport the signal through a digital circuit. This results in a latency of 15-20 msec. The effect of a failing precision in the timing of the signal transfer to the speakers, respectively the subwoofer, impairs an authentic audio reproduction, creates a compressed sound and adds a harsh tone to the music.

Control your home theater and your 2.1 audio setup
By using the low pass and high pass filter, the sound performance of your individual speakers can be optimized. When directing the low frequencies to the subwoofer, more energy to the main speakers will be released. To ensure an even volume of the speakers and the subwoofer, the gain on the high pass and the low pass filter can separately be controlled.

Analog Room Correction – prevent “Room Boom”, the annoying pressure resonance
Room correction is a matter of identifying and eliminating room resonance. The one specific resonance that creates an unpleasant and disturbing sound is a pressure resonance resulting from the given size of the room – subjectively, it feels like a “boom” emanating from the speakers. To eliminate this room specific resonance, the Aavik amplifiers can adapt their audio performance and make allowances for any given room size. Both the low pass and high pass filter allow the listener to set the exact frequency progress around those low frequencies which cause this disturbing ‘Boom’ effect.

Volume control

Affects the sonic experience.
The Aavik line stage boasts a unique, inverted, virtual GND** amplifier topology, which provides the highest stability. The feedback gets so powerful that it allows to damp the signal to a gain lower than 1. This preserves the full signal with the lowest S/N Ratio*** – no matter if you turn the volume up or down. This will provide your loudspeakers with a clear and distinct information flow to make even the finest details of timbral and textural nuances audible on an extremely quiet sound stage.

The Tesla coil principle

The principle is to have two coils that are wounded in each direction / a coil and a counter coil. In Ansuz words: “a double inverted coil” – the two coils are both carrying voltage – and when the Tesla coil encounters a voltage spike a counter spike is activated in order to eliminate the noise. As Noise spikes are pure voltage and carries virtually no charge, the cancelation is quite good, but not 100%. By adding more P-TC coils in parallel the performance increases. By implementing this the perceived blackness in the music improves significantly.

Ansuz Tesla coils are available in various types as they complement each other in terms of strengths /weaknesses.

Active Tesla coil

Effective noise killer.
The active Tesla coils are power supplied which secures a remarkable lower impedance and thus a better ability to eliminate noise. The active version is about three to four times more efficient than passive Tesla coils.

Active square Tesla coils

Impressive noise reduction.
The active square Tesla coils are embedded in our circuitry boards – one coil on the top and the counter coil on the rear side. The principle is exactly the same as the active Tesla coil and thus a great ability to eliminate noise than the passive Tesla coil.

Analog dither technology

Extended musicality.
This technology is another noise reduction technology. The technology origins from radars where it secured a stronger signal and thus a wider range. Ansuz active Tesla coils are sending pulsated signals in well-defined frequencies. These signals are sent in counter phase and thus eliminating the noise floor whereby the music signal is significantly increased.

Ansuz Active Tesla coil

Ansuz Active Square Tesla Coil technology

This is an active noise suppressing element that rely on spike noise cancellation. The way they work is to have a double inverted coil connected to the power conductors, when the AS-TC dual coil encounters a voltage spike a counter spike is developed in the counter wound section of the AS-TC coil. As Noise spikes are pure voltage and carries virtually no charge, the cancelation is quite good, but not 100%. By adding more AS-TC coils in parallel the performance increases. And with that the perceived Blackness in the music improves significantly So, AS-TC is similar to A-TC. But where the A-TC technology is mounted on the circuitry boards the AS-TC coils are imbedded in the circuitry board itself. They are not as efficient as the top mounted coils, but they are very compact and more cost efficient.

Ansuz Analog Dither Technology

The Ansuz AD technology is responsible for the analog dither we use in a wide range of our product, The technology origins in radars where results to most engineers astonishment was better in live situations (in planes, on boats) than in stationary land fixed systems, They concluded that the vibration of the planes and ships aided the aided the radar and sonar performance.. Thus, was the idea of analog dithering born. The dither is added a very low-level random noise, by modulating the noise floor it’s possible to see what’s below it, and thus get a clearer picture of the full content of the recording.
