PowerBox D-TC Supreme


World-class performer in signal transmission

The Ansuz Powerbox D-TC Supreme is the ultimate power box . Equipped with Ansuz most sophisticated and most advanced noise reduction and dither technologies, this is a world-class, top-of-the-line power box. Ultra-fine, authentic and natural resolution of the entire sound spectrum from the very high pitch to the deepest bass opens up a new dimension of musicality and creates a jaw-dropping holistic soundstage that defies any further description.


Technologies and Components

Delivering clean low voltage.

The Ansuz PowerBox is developed with the aim of delivering clean low voltage to the cables and speakers. This is overall solved by reducing the noise heavily and controlling the resonances. Various Ansuz technologies and principles are used in order to deliver a huge soundstage with openness musicality and details. The recurring technologies are securing that almost no noise is transferred from the PowerBox to the cables and speakers.

Natural-based composite cabinet material

The cabinet design is an important Ansuz characteristic and is design to eliminates sonic distortion. 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. Ansuz’s sister company Aavik 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 Ansuz’s quest for the ultimate music experience.


The Tesla coil principle

The key operating principle of the Ansuz Tesla coil is to have two coils wound in opposite directions – one coil and one counter coil. In Ansuz words, this is called “A double inverted coil”. The two coils both carry voltage, and when one of the Tesla coils encounters a voltage spike, a counter spike is activated to eliminate the noise. Since noise spikes are pure voltage carrying virtually no charge, the cancelation is quite good, but not perfect. Adding more Tesla coils in parallel, increases the noise cancellation and the perceived blackness in the music increases significantly along with the purity and clarity of the sound. Ansuz uses various types of Tesla coils, as their individual properties ideally complement and reinforce each other.


Active square Tesla coil

Embedded efficiency.

The active square Tesla coils are embedded in our printed circuit boards – a coil on the top and the counter coil on the back. The principle is exactly the same as the active Tesla coil and thus has a greater ability to eliminate noise than the passive Tesla coils.




Active cable Tesla coil

Active anti aerial protection.

The active cable Tesla coil is wound directly on the outer part of the cable and protects the signal from absorbing the airborne RF noise. This noise is absorbed in the Tesla coil. The active version is about three to four times more efficient than the Passive cable Tesla coil. 




Analog Dither technology

Musical information from the depth.

Analog dither technology originated in radar, where it ensured a stronger signal and thus greater range. Ansuz adopted this technology. Their active Tesla coils send pulsating signals at precisely defined frequencies. These signals are sent in anti-phase. This significantly amplifies the musical signal and eliminates the background noise floor.




Passive cable Tesla coils

Airborne noise elimination.

The passive cable Tesla coil is wound around the outer part of the cable and protects the cable from absorbing disturbing airborne RF noise. This noise is absorbed in the Tesla coil and eliminated in the counter coil. When voltage flows through the cable’s conductor, which is wound in the opposite direction, it operates as this counter coil, which eliminates the RF noise.



Ansuz active Tesla coil

Minimized Impedance.

The active Tesla coils are current fed, which ensures a much lower impedance and thus, a much better ability to eliminate noise. The active version is about three to four times more efficient than passive Tesla coils.
