A Short History of the Ultimate Audio Video Room

The mere existence of a masterpiece usually implies the preexistence of numerous simpler masterpieces,each having taken a long time and painful efforts to be achieved. The Goldmund Media Room springs from such a Darwinist evolution over decades of constant refinement, each of its parts, amplifiers, speakers, etc… meticulously optimized by passionate Goldmund Research Teams.

In the 80’s and the 90’s, Goldmund developed quite a few audio products among which speakers that were optimized as it was usually done in the last century: painful tuning of crossovers by soldering capacitors and inductors and measuring the result.

By early 21st century, computer modeling had made these practices obsolete and allowed speakers to be completely mathematically optimized before being even built. Goldmund adopted this new technology enthusiastically and our speakers became more accurate.

Proteus 2-channel

In 2005, the first elements of the Goldmund Proteus Computer Modeling software were released, allowing the modeling of a group of drivers. The first application of Proteus was complete 2-channel configurations. Each driver being powered separately, the crossover could be digitally built in a DSP-equipped preamplifier, and the correction of Phase and Time became possible. Proteus finally provided the complete correction of a system in Amplitude, Phase and Time, something never achieved before. This was called a Proteus 2-channel system.

Interestingly enough, the considerable progress achieved was easy to apply to speakers from other brands. Proteus could model them as easily, and several competition speakers were "optimized" by Proteus for end users, distributors, or even in agreement with the manufacturer. Today’s best Proteus 2-channel Goldmund systems, usually based on a pair of full Epilogue, are the state of the art of two-channel reproduction.

Proteus Evolution to Multi-channel Systems

But the next step of the evolution is even more interesting. Without losing anything from its 2-channel quality, such a system may progressively be evolved into a multi-channel system by adding amplifiers and speakers. Using the Universal Configurator of the Goldmund preamplifiers and processors, a complete multi channel system can be installed and adjusted with a minimum effort.The revolution is that the evolution will be achieved without any loss in the system’s 2-channel quality. Why is it a revolution? Because this is in absolute contradiction with the common practice of making multi-channel systems that are quite poor 2-channel performers. In fact the Proteus evolution to multi-channel will even provide some sonic improvement to the 2-channel performance thanks to the better acoustical control of the room it provides.

From a Multi-channel System to a Full Goldmund Media Room

However, even such a high-performance multi-channel system made of Goldmund equipment is not yet a Media Room as it can still be perfected. The room itself has to be completely modeled by the highest version of the Goldmund Proteus Software, incorporating its acoustic specificities. This is a much more ambitious work and it took years of development for Goldmund to achieve this level of perfection. All the parameters of the room are carefully detailed, collected and integrated by the model to produce an optimal configuration. These is include the dimension of the room, the number of seats and their position in the room, the construction materials used, the altitude and average humidity of the room, the decoration materials used (carpet, walls, draperies, seat cushions etc), the type of cloth used to cover the speakers and many other specificity for each project our teams work on. To create a Media Room, the Proteus model will first establish how many speakers are exactly needed and where they should be exactly located for the maximum audio level that has been chosen by the customer. This implies possible addition or displacement of speakers to optimize the room. It will also be the time to optimize the position of speakers for the Video constraints and the decoration of the room. After the room installation is completed, the same Proteus Model will issue the individual correction to apply to each driver located in the room and this in Amplitude, Phase and Time. These corrections may be loaded either in the central Universal Preamplifier or in the attached amplifiers, if equipped with a DSP card. To make this possible, it is important to notice that each single driver must have its own power amplifier.The considerable Modeling work necessary to elaborate a Media Room to perfection is a service provided exclusively for the end-user by the Goldmund Acoustics Laboratory located in Geneva, Switzerland. It is the only place where the model can be run. The price of such a special project is quoted by the Laboratory when the first room description is provided.

iPhone, iPod Touch and iPad Remote Control for the Goldmund Media Room

iPad

iPhone, iPod Touch and iPad remotes are coming to the Goldmund Media Room, providing the most logical tools to control the complete Media Room with widely available pre-existing devices. In addition, the local Goldmund Media Room control system may be integrated inside a pre-existing House Control system without any boundary.

A 3D Demo Now in the Metis Media Room in Los Angeles

Metis System

The first 3D demo in the Goldmund Los Angeles Metis Media Room has occurred this month. It associated one of the latest 3D plasma screens with the recently installed Metis Media Room in the Goldmund House bedroom.

This configuration is ideal for domestic installations in smaller rooms such as offices and bedrooms. With the Metis systems the incredible qualities of the Goldmund Media Room are now made available at affordable prices starting around 60k US$ .

Leonardo & Time Alignment: New Demonstration in Los Angeles

Goldmund House Los Angeles

An interesting demonstration is now available in the Goldmund House in Los Angeles. It shows the sonic improvement brought to 2-channel and multi-channel systems by the Leonardo technology built inside Proteus. A blind test setup has been installed to demonstrate the sound improvement brought by the time distortion correction, a sonic improvement that nobody has ever had the occasion to test before.

It will be used by fundamental research teams associated with the company, by the press and will convince the most demanding audiophiles.
