EXTREME TECHNOLOGY
SWISS MADE
Goldmund's unwavering pursuit is to deliver unparalleled concert-like sound experiences by constantly pushing boundaries and employing innovative solutions. For over 40 years, our world-class engineers have developed cutting-edge technologies and incorporated superior external advancements, enhancing both convenience and performance. Every element, from links in the chain to individual components, embodies their wealth of knowledge and expertise.
PROTEUS LS©
loudspeaker modeling Alogrithm
Before conceiving any Goldmund speakers, a research stage for modelling its ideal parameters is necessary.
To ensure sound transparency of our loudspeaker systems, the modelling process enables every individual component as well as the system overall to be under control.
Proteus LS is a mathematical software based on several specifications such as loudspeaker system solution, enclosure shape and volume, T&S parameters, driver localisation, and diffraction at box edges, to name a few. The modelling calculates the loudspeaker system in impedance, volume velocity, membrane displacement, and sound pressure anywhere in space, amplitude, phase and group delay.
Our proprietary digital filtering calculations and Leonardo® time correction are included in the Proteus LS software.
PROTEUS HT©
Home Theatre modeling Software
We know each room is unique, thus we opt for bespoke multichannel solutions rather than ready-made ones.
Goldmund proprietary software – Proteus HT – is responsible for modelling each individual home theatre and enables the best performance each room type can achieve.
Proteus HT factors in the geometry of the room and the constraints of construction and decor. To ensure a complete and coherent immersion, it outputs screen size, listening position, optimized number of drivers and their models, driver placement in the room, and settings in terms of gain, delay, and signal mixing.
Proteus HT can be applied to an infinity of home theatre solutions comprising in/on-wall and/or external elements from Goldmund collection. High-end speakers from different brands can as well be integrated into Goldmund systems. All Goldmund speakers derive from Proteus LS modelling and include the Leonardo® time alignment.
Proteus HT is patented as “Method for creating an audio environment having N speakers“.Before conceiving any of Goldmund speakers, a research phase for modelling its ideal parameters is undertaken.
LEONARDO TIME CORRECTION®
Phase Distortion Correction Algorithm
In the past, audio distortions were supposed to rely only on amplitude non-linearities. But recent studies tend to consider the phase non-linearities equally.
Phase distortion alters the sound realism by affecting the size and depth of the sound stage, the ability to perfectly identify the location of the different sound objects, the tightness of the bass, and other parameters. Working on the transients, this distortion also modifies the timbre of the sound source. The Leonardo® time correction suppresses most of those sound alterations by digitally realigning the signal frequencies in time. The enhancements in terms of DSP’s power and performance allowed Leonardo to apply corrections on an even wider bandwidth, giving hence birth to Leonardo 2. The latest Leonardo 2 version is currently deployed in every speaker of Goldmund current collection. Thanks to this deployment, the listener’s brain can fully focus on enjoying the sound instead of spending energy in the correction process.
DIGITAL SIGNAL PROCESSING
Goldmund stands as a trailblazer in the HiFi industry, particularly in the realm of Digital Signal Processing.
Goldmund is a pioneer in powered speakers with digital filtering in the high-end HiFi industry, having launched its first model in 2003.
Our powered speakers feature amplifiers directly connected to the speaker membranes, displaying one DAC per membrane. Physical crossovers have been replaced with software-based filtering controlled by advanced DSP (Digital Signal Processing) technology.
By directly linking one amplifier to each membrane, we achieve superior driver control. The reduction of analog cables minimizes signal loss, ensuring greater audio fidelity.
Our DSP configurations are meticulously calculated using the Proteus mathematical model and integrate Goldmund’s proprietary Leonardo time-correction software to address phase distortion. The DSP settings also encompass critical parameters such as gain and delay.
This cutting-edge approach allows us to push the boundaries of speaker design and refine speaker behavior with unparalleled precision—delivering the purest, most immersive sound experience possible
TELOS®
Amplification System
As a general rule, the more powerful your amplifier, the better it will control the speakers.
Speaker control is exerted in two ways: by giving them enough power to produce high-quality and undistorted sound; and by controlling the drivers better preventing them from producing parasite sound. This is especially true in low frequencies where drivers’ range of to and fro movement is higher, increasing the likelihood of unwanted sounds that affect the purity of the signal.
Telos® amplification technology significantly reduces the harmonic and intermodulation distortions by improving the linearity of all stages. Telos® uses a higher bandwidth circuit with minimal group delay distortion inside the audio bandwidth.
Telos® amplifier input circuitry includes the latest version of Alize Digital/Analog converter circuits for enhanced coupling with Goldmund Universal Preamplifiers. Separate input and output stages prevent feedback between high and low current circuits and improve the Mechanical Grounding™.
One of the most important sonic improvements provided by the latest Telos circuit is its «driver control». Obtained by lowering the output impedance of the amplifier to an extreme degree, it provides a much higher quality of micro-dynamics and helps large woofers overshooting and delivering a boomy bass.
Telos® amplifies the audio signal with incomparable purity and transparency whatever the volume, without distortion.
THEMIS
Audio Board
Goldmund’s innovative Themis technology will be featured in Goldmund future products and marks a significant advancement in audio fidelity. Themis consists of a dedicated audio card for each channel – left and right -, ensuring independent processing. This meticulous separation minimizes noise and crosstalk phenomema, preserving the audio signal’s integrity.
Themis boasts a next-generation DAC, with optimized analogue circuitry for enhanced sound quality. Themis significantly minimizes Total Harmonic Distortion (THD), i.e., the unwanted residues in the electrical signal, resulting in an exceptionally linear signal with near-zero distortion.
Each channel has its own DAC and volume control, ensuring the purest audio signal and maximizing dynamic range. The absence of noise during operation allows handling a broad spectrum of volumes without compromising clarity.
The Themis card features innovative locked mechanical shielding to block electromagnetic emissions and includes a newly designed, highly precise volume controller, further elevating the audio experience.
Designed as a modular system, Themis offers unparalleled ease of maintenance due to its independent functionality from other components, enhancing overall performance and reliability.
Goldmund’s Themis technology delivers unmatched clarity, dynamic range, and signal purity through advanced, carefully crafted components and brings a fresh approach to preamplification blending Goldmund’s expertise and commitment to innovation.
MECHANICAL GROUNDING™
Product Building System
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 colouration. As a result, there is no overemphasis on certain tones and the sound preserves its naturalness.
ALIZE
D/A Technology
Goldmund Digital to Analog technology uses a specially designed, unique kind of ultra-linear, time-coherent analogue filtering, achieving a time error smaller than 100 picoseconds in the bandwidth.
Alize D/A circuit is constituted of three major parts:
- A new digital interface with quartz locked frequency that cancels all jitter from the signal;
- Ultra-fast D/A circuitry from continuous improvements in the Alize topology;
- A new kind of complex analogue multi-stage filtering with extreme time alignment providing a unique aliveness and exceptional «Recognition Factor».
