EXTREME TECHNOLOGY ONLY
Before conceiving any of Goldmund speakers, a research phase for modelling its ideal parameters is undertaken. 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.
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 type of room 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.
LEONARDO® TIME CORRECTION
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 identify which direction the sound comes from, 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. Thanks to this deployment, the listener’s brain can fully focus on enjoying the sound instead of spending energy in the correction process.
As a general rule, the more powerful your amplifier, the better it will control the speakers. This 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 intermodulation by improving the linearity of all stages and considerably decreasing the time distortion. Based on Leonardo® research program, the 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.
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:
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».
