SWISS MADE

Goldmund’s goal is to always offer the best, to reach that limit unknown to others, no matter what the means necessary to achieve it may be, and which in the end must translate into an unmatched sound experience. For that reason Goldmund studies and analyzes the weak points of every link in the chain, researches the causes, studies the problem, and proposes a solution. Each link in the chain, each device, is the result of this compendium of knowledge and know-how that includes the AC plug itself, the chassis and its vibrations, the signal input and output, the processing, etc. As a result of this research program, a series of technology solutions arises.

Proteus HOME THEATRE modeling

The Proteus modeling for home theatre is a Goldmund proprietary software enabling ideal performances in all types of room. It takes into account the geometry of the room and the constraints of construction and decor.

In order to ensure a complete and coherent immersion, the software calculates screen size, listening position and optimized number of drivers, their models, individual locations in the room, and settings in terms of gain, delay and signal mixing. It must be emphasized that the Proteus modeling for loudspeaker systems is included in the Proteus software for home theatre.

This Proteus technology may be applied to an infinity of home theatre solutions comprising in-wall elements only, a mix of in-wall and external elements, external elements only, or even high-end speakers of different brands integrated to a Goldmund system.

Loudspeaker technologies

Goldmund employs numerous advanced engineering and manufacturing techniques in the development and production of its loudspeaker systems, such as:

=> heavy aluminium cases to minimize the box resonances

=> mechanical grounding to evacuate vibrations to the ground

=> Proteus modeling to ensure the audio transparency and the precise compliance with the specifications

=> powered system to improve the capability of “holding” the driver tightly

=> digital transport of the signal to minimize quality loss in the audio chain and digital processing to enable perfect filtering, gain and delay setting, phase distortion correction and room equalization

=> wireless technology to make the integration in interior design easier and improve the WAF

PROTEUS LOUDSPEAKER SYSTEM MODELING

With the aim of ensuring the sound transparency of our loudspeaker systems, we have implemented a modeling procedure enabling any component, as well as the whole systems themselves, to be under control.

Proteus is a mathematical software based on a huge number of specifications such as loudspeaker system solution, enclosure shape and volume, T&S parameters, driver localisation, diffraction at box edges and more. The modeling enables the loudspeaker system to be calculated in impedance, volume velocity, membrane displacement and sound pressure anywhere in space, in amplitude, phase and group delay.

The calculations of our proprietary digital filtering and Leonardo time correction are included in the Proteus software.

Time correction to prevent audio distortion

LEONARDO TIME CORRECTION©

In the past, the audio distortions were supposed to rely only on amplitude non-linearities, but recent studies tend to consider the phase non-linearities equally. The phase distortion alters the sound realism, the size and depth of the sound stage, the localisation, the tightness of bass, and other parameters. Working on the transients, this distortion alters also the timbre of the sound source.

The Leonardo correction suppresses most of those sound alterations by realigning digitally the signal frequencies in time. Thanks to this deployment, the listener brain can focus on the sound itself instead of spending energy in the correction process.

MECHANICAL GROUNDING

Introduced by Goldmund in 1982, the “Mechanical Grounding™” building technology uses physics laws to evacuate vibrations from any structure, allowing lower resonance from speakers but also from electronics, where mechanical vibrations are one of the major sources of coloration. As a result, there is no overemphasis on certain tones and the sound preserves its naturalness.

DIGITAL/ANALOG TECHNOLOGY

The Goldmund D/A technology uses a specially designed, unique kind of ultra-linear, time-coherent analogue filtering, achieving a time error of less than 100 picoseconds in the bandwidth. The three major parts of a D/A circuit are :

=> A new type of digital interface with quartz locked frequency that cancels all jitter from the signal.

=> Ultra-fast D/A circuitry : Alize topology is undergoing continuous improvements.

=> A new kind of extremely complex analogue filtering (multi-stage) with extreme time alignement providing unique aliveness and exceptional « Recognition Factor ».

MAGNETIC GROUNDING

The Magnetic Grounding technology is used to improve the reading of the latest ultra-fast disc readers in DVD and Blu-Ray player mechanisms. The Magnetic grounding utilizes a very strong magnetic field to damp the overshoot of the lens assembly, the most typical source of reading errors. The magnetic grounding prevents these errors while providing more precision in the signal reading.
