Discover HELIXIR™ Technologies
« Advanced Natural Digital Filter »is an important step forward in terms of digital processing dedicated to the human auditory system, with excellent image rejection spectrum of images without compromising signal readability. It uses two powerful DSP running at over 98MHz. Their synchronization it is guaranteed by registered lines directly on the PCB.
The High Resolution DITHER Technologies allows, in addition to a greatly facilitated reproducibility, the reproduction of micro details of the signal despite the addition of a digital noise. This may seem paradoxical, but through this process, we finally mastered the spectral distribution output analog modulators. This is a significant breakthrough in the field of digital to analog conversion commonly used in the mastering studio.
A Digital Phase Locked Loop with 32Bits depth allows a perfect synchronization of the SPDIF flow and cleans it of any jitter, while ensuring optimum reading of the data frame. The generated reference clock has a remarkable spectral purity with a high jitter performance of less than 20ps.
The HRDDAC supports DSD x64 in SDIF2 or SDIF3 format. The selection is automatic, using “RAW” format
SDIF2, or phase modulated, SDIF3. These formats are used in the studio, because it is the only professional standard. The DSD shows the format that will probably be the most used in the near future.
Laser calibration technology is the only way we can offer the accuracy required for the system, in terms of intrinsic accuracy of course, but also in terms of noise, allowing us to have a compact area where the R / 2R cells are switched, ensuring a very low noise level. An insulating substrate allows to have a stereo chip, operating in dual mono, as if these two channels were mounted in separate housings.
The balanced inputs have a common mode rejection ratio of 100dB , ensuring the transportation of analog information over long distances without increasing the ground noise of the system. This measurement is performed at 50Hz, it gives you an idea of its incredible immunity to low frequency noise of installations of electrical distribution networks
Through the owner “Extrem Bass Control System“, with an intelligent loop device, the HPLSD500 reaches full control on the movement of the loudspeaker diaphragm, this ensures an accurate, energetic and full of details sound. Through it’s.real-time working in analogue environment, it is able to have full control over the widest possible range of speakers
Reserve power and dimensioning of the power stage allows the HPLSD to drive close Ohm loads of such electrostatic speakers that reach these limits beyond 10KHz. Similarly, when to change the position of the membrane of the speaker in the opposite direction this reserve in current draw is helpful and provides an extremely rapid action.
The open loop gain of the amplifier stage is 147dB, ensuring an almost immeasurable distortion. The distortion spectrum has a spectral distribution of the form K / f guaranteeing a warm sound, very quick and defined both. Heat typical “tube” and the speed of the transistor combined togheter to provide a unique listening pleasure.
The thermal control system is assumed by a processor ensuring operation of the transistors of the output stage at 100 ° C at the substrates. This thermo-regulation ensures no thermal distortion and ensuring effective cooling during extended energy demand.
A power supply type “shunt” in pure Class A, a reference ultra low noise voltage, a gain of 120dB control loop, a large quantity of capacitors, an optimized design with small islands masses, give our equivalent analogue systems a lead battery with an energy margin of a factor of 10.
Printed maps are subject to all care of Helixir ™. In addition to using a copper with a purity of 99.99%, we use a new method to deposit electroliquement Gold, without it being deposited in pyramids. The spread of the signal on the card can be in optimal conditions.
Cryogenic processing makes a perfect crystallization of materials allowing to extract the essence, either in conductance or in terms of wave propagation purity. Many components as well our circuit undergo this treatment.
