Aavik P-580 Power Amplifier

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.

Aavik UMAC™ amplifier

Unmatched audio control.
At Aavik we utilize the patented UMAC™ amplifier technology. This technology was developed to avoid the design flaws of traditional switching amplifiers. UMAC technology primarily targets two areas of modulated amplifier design. Firstly, the PWM* generation is produced with sine wave modulation rather than the more common triangle modulation. The benefit is that sine waves create far less high frequency noise than triangles, no sharp corners, and thus require far less inductive filtering at the output. The lower inductance in the output gives the amplifiers a much better damping factor and thus a distinctly better speaker control. Secondly, the advanced dual mixed mode feedback allows damping factors that are characteristic of only the very best linear amplifiers.

*PWM: Pulse-Width Modulation

Resonant mode power supply

Quiet but extremely powerful.
This Aavik series is designed to ensure massive power resources with ultra-low noise. Unlike the square waves used by conventional switch mode power supplies, this Aavik series boast a resonant mode design which is principally driven by sine waves.

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 but could be 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.

Copper chassis

The flagship 580 series are equipped with an inner chassis in solid copper. The effect of this is a further reduction in the hysteresis, which secures more energy and power to the music.

Switchless optical gain selection

LDR based.
The LDR (Light dependent resistor) is ultra quiet thanks to the switchless principle. The traditional MOS-FET switch arrays and relays create much more noise. They suppress subtle sound details and unnaturally color the tone.

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.

Anti aerial resonance coil technology

Prevents airborne noise.
All cables and cable screens are acting like antennas for airborne RF noise which of course is a huge problem. The passive cable Tesla coil is wounded on the external part of the cable and protects the signal from absorbing the airborne RF noise. This noise is absorbed in the Tesla coil.

As there is a voltage running in the conductor itself, and it is wounded in the counter direction – this is used as the counter coil and the RF noise is then eliminated.
