H-Pro Acoustic System

The SteinMusic H-Pro Acoustic System is a very efficient system for optimizing room acoustics. It is specially designed for use in concert halls and consists of active and passive components. Their interaction optimizes the acoustic conditions, for the musician as well as for the listener. For the former it is easier to express their playing, the listener can follow the musical events better. Because the sound carries better, and is thereby also more understandably perceived. The SteinMusic Hpro Raum Acoustic System consists of active and passive elements, which have a positive influence on the acoustics.

Air as a medium of sound transmission The basic requirement for the transmission of sound waves is a medium that can transport them. When playing music, this medium is basically air. Air is known to have a multitude of properties: Pressure, compressibility, temperature, humidity, oxygen content, charge, odorous substances or other suspended matter. But above all, air has one thing: mass. More precisely, 1.293 kilograms per cubic metre.

A concert hall such as the Elbphilharmonie Concert Hall with 2100 seats and a volume of 23,000m3 thus comes to about 30 tons of room air. These air masses do not have to be moved completely to transmit sound, but their inertia is still involved.

On the other hand, the vibrating components of the instruments, some of which have masses of only a few grams, have to transport their vibrations through the large air volumes.

The Hpro system in comparison to classic acoustic solutions The Hpro system is designed to complement classic acoustic solutions. However, it is also an effective alternative where the use of damping elements and diffusers is not possible for structural or optical reasons.

Why does the SteinMusic Hpro system work in large halls as well as in small rooms, where the air mass is much smaller? Experience shows that two phenomena occur when using the SteinMusic Hpro system: First, the air “carries” the sound better, which also leads to the common statement from musicians that it is easier for them to play or sing their instrument.

The direct feedback of one’s own actions via the auditory system is more direct, as is the perception of this by the audience. On the other hand, the reflection behaviour at the interfaces changes.

Small rooms and even cars are acoustically perceived much more spacious when using the Hpro system. Which significantly increases the general well-being.

Palao Reina Sofia

Cyprus Symphony 

The rehearsals took place without the SteinMusic Hpro system, on the recording days the SteinMusic Hpro system was installed in the hall.

Comment by Jens Georg Bachman, Artistic Director & Chief Conductor of the
Cyprus Symphony Orchestras:

“On the CD recording of the Cyprus Symphony Orchestra the clarity and transparency was higher with the Hpros and BSpros.
The sharpness and narrowness of the instrumental sound was rounded off compared to the previous days without Hpros and BSpros.
Nuances of recording with Hpros and BSpros could be fine-tuned during cutting.
The atmosphere in the room (the musicians were not aware of the presence of the equipment) was calmer, more relaxed, but more concentrated, more focused than in the days before.
The room acoustics were much clearer, more differentiated.
All in all a very productive work, without distraction, with good focus and high productivity especially towards the end, where concentration and power tend to decrease.

 

Cinelab Studios Moscow

Cinelab Studios Moscow

Cinelab, located in Moscow, is a big studio complex for audio recordings and cinema sound. Here you find all you may imagine, like perfect audio recording studios, numerous dubbing studios, two
movie theaters where they may handle 680 channels of sound, one of them fully equipped with Dolby Atmos.

At 10 November 2017 we have been invited to demonstrate the H Pro room acoustic system here.
We started recording some tunes played by Arcady Ivannikov, one of the best Russian guitarists.
His guitar was recorded with 8 microphones, 6 in the nearfield and 2 farther apart and mounted about 2m high for the ambience.

Then we mounted 6 pieces of H Pro and two BS Pro Signatures in the recording studio, and Arcady played the same track again.
Already during the record in the monitor room it was obvious that the sound has been changing from the character of a recording studio more to a very good concert hall, and the sound became more
substantial and expressive.

Here you find both recordings with all 8 individual channels:

Helmut Hack in the magazine Fidelity № 41 | 01/2019:
“At the beginning of the hearing test, the first thing that convinces is the quality of workmanship…
…then Aretha Franklin’s “Chain of Fools” sounded so free and expansive, so little dull and cloudy, that I was able to experience deep inner satisfaction in two ways at once.
With the Ametrin-1, Holger Stein has achieved a great success that goes far beyond the usual requirements for stability and geometry.
It offers the cartridge a base that simultaneously hugs, supports and stimulates”.

H2 Room Accoustic System

H2 Room Accoustic System

H2 Room Acoustic System

Experience next generation audio tuning and optimize your room acoustics

With the H2 Room Acoustic System, you extend the boundaries of your auditory space and at the same time give more energy to the music as a whole. Give the stage more size and individual musicians significantly more plasticity, and experience a significant increase in power over the entire spectrum of frequencies.

The Basic Idea behind the H2

The basis for the transmission of sound waves is a medium that can transport them. When playing music, this medium is basically air. Air is known to have many properties: Pressure, compressibility, temperature, humidity, oxygen content, odorous or other suspended matter. Above all, however, air has one thing: mass, and at 1.3 kg per m³ not too little. The air mass in the passenger compartment of a passenger car is between 3 and 5 kg, depending on its size. A small room of 30 square meters and normal ceiling height comes thereby on approximately 100 kg air mass, a concert hall with 1800 places and 15 000m³ volume on 20 tons. On the other hand, diaphragm weights of less than 1 gram for tweeters to over 100 grams in the bass range are used to excite these air volumes with sound.

Oscillating parts of instruments have a wider range with respect to their mass. Just think of a harmonica or a concert grand piano. First experiences that crystals have an influence on the acoustics we found out rather by chance: After a new decoration of one of our studios where rose quartz was also used, we had the impression that something had changed in sound. These were little things, but it turned out that everything was exactly the same after we removed these crystals. These changes were also reproducible for other people and over a longer period of time.

Further development

Now the question arose as to how far this principle can be used to achieve a lasting positive influence on room acoustics. This was a rocky road, because many of the ideas that were then processed in a structured manner achieved changes, but unfortunately none that we found positive. In the end, however, we still found two ways of activating crystals, which proved to be extremely positive when used properly: One by electronic means, and a second by quantum physics.

Practical implementation

Over the years, we have developed an all-round harmonious systemfrom this. This system consists of two active H2s as well as the passive Blue Diamonds and Blue Suns. Herewith you can acoustically optimize every room individually. For mobile applications there is a smaller model, the H1. Its compact design makes it easy to use anywhere. There are also smaller passive elements, the Blue Stars.

Practical application

In rooms it is recommended to place one H2 in each corner of the room, always in pairs. In larger rooms, correspondingly more pairs can be used in symmetrical arrangement. These include the passive elements, Blue Diamonds, Blue Suns, Blue Stars.
In a car the harmonizers can be placed in the center console. A second one in the back of the interior improves the effect, but is not absolutely necessary. Fixation of the passive elements with plasticine from the automotive sector.

Easy handling

Harmonizers and Blue Suns must be positioned in the right place for optimal effect. For the H2 there are matching stands and wall brackets. H2 are available in black and white, and can even be placed behind curtains or integrated into furniture. This also applies to the passive elements that are allowed to hang behind a canvas, for example, and which can also be color matched. H2 are current-free through battery operation. Batteries last more than 2 (alkaline) or 8 (lithium) years in continuous operation. In the car the placement of the H1i n the side pockets of the doors is ideal. Here too, the battery life is extremely long with 3 years of continuous operation. When using the SteinMusic H2 system, experience shows thattwo phenomena occur: First, the air “carries” the sound better, which also leads to the common statement of musicians that it is easier for them to play or sing their instrument. The direct feedback of one’s own actions via the auditory system is more direct, as is the perception of this by the audience. On the other hand, the reflection behavior at the interfaces changes. Small rooms or automobiles are thus acoustically perceived to be much larger when using the H2 System. This is also very beneficial to general well-being.

Robert H. Levi, President of the LA/OC Audio Society

“Once engaged, prepare yourself for the performance to come to life in your room like never before. In my opinion, there is nothing on the market even close to the importance and usefulness of the Harmonizers.”

Dave Clark – Positive Feedback Issue 62

“Don’t consider them a tweak, but a necessary component for your system. One that will allow you to fully realize what your music can sound like. Holger is really onto to something here… something really wonderful.”

Review on Audiodrom by Martin J.

“The Steinmusic H2 system is … beyond any description.
…the Steinmusic devices have the power to transform the listening space to the point you’ve never dared to dream of.”

Image Hifi – November 2022

“The stage opens up and the listening room feels like it’s been atmospherically cleaned.”

Clement Perry – Stereotimes

“The H2, in my opinion, is nothing short of breathtaking.”

Ron Cook – Stereotimes

“I was immediately taken aback by the transformation of sound that began as soon as the music started up,… The sensation that something special was occuring never went away. First, there was an enormous increase in the size and layering of the sound coming from around, in front of, and behind my loudspeakers. The Harmonizers created an even better holographic effect on the soundstage compared to what I formally had.” Dan Secula
“In the world of the high-end, every once in a while, a product comes along that is so inherently good in what it does that it literally, “changes the game” in some meaningful way. The Steinmusic Harmonizer System is such a product. One thing is certain; this is not a tweak that you have to listen to for days in order to determine if you REALLY hear an improvement in your system. This type of change hits you like the proverbial “ton-of-bricks.” It’s simply magical.”

Bill Gaw – Enjoy the Music

“Then they turned on the four units, and the side and front walls disappeared, with the room suddenly becoming several feet wider and deeper, extending through the front wall to my back yard. In addition, one could almost hear the roof of the cathedral become a solid object, and the hall ambiance extending for about four feet behind me before disappearing.”

Wayne Donnelly –  Enjoy the Music

“The audible evidence that the Steinmusic Harmonizer system is a superior room conditioning product is inarguable, and the ability to achieve a glorious-sounding listening room without the need for those big ugly traps and diffusers cinches the deal!”

Daniel Plaßmann – Audiophil Online

“What Steinmusic offers here surpasses – at least in our listening room – all the differences we have heard between the units so far. The music is changed in a way that is so fundamental and at the same time natural that one wonders how one ever endured without a harmonizer.”

Jochen Reinecke – Fidelity Online

“Well, and what then happened after switching on at my home was – please don’t say anything now! – was surprising: Increasingly subtle, but over the next few hours actually audible and noticeable, the listening room seemed to transform into a kind of “protected zone” within the baselines formed by the harmonizers. The sound image seemed clearer, more direct, better spatially sorted, it seemed to grow, but without being artificially distorted.”

Kai Ekholm – Inner Magazines

“I’d recommend Steinmusic Harmoziners to all experienced audiophiles who are ready to enter into a new zone of audio pleasure without prejudices.”

Description

Like the Speaker Matches, the In Line accessory elements remove EMF field distortion over a wide frequency spectrum. However, it is more the inductive origin and elimination of such distortion that is considered here. Any conductor through which a current flows generates an electric field. This field, by re-induction into the conductor, can lead to disturbances in an upper frequency range, which we perceive acoustically as high-frequency distortions, thus affecting the spatial sound image.

To visualize the field lines and their vectors and strength, we make use of the so-called left-hand rule: we close our left hand around the conductor in question and indicate the direction of the current (the signal) with our thumb. The bending direction of the fingers now describe the direction vectors of the resulting field lines. Inside an in-line element, the conductor is now twisted in a chaotic way [There is a matrix of purest copper, silver or gold in which the direction of the field lines are completely disordered], and thus a chaotic variety of forming field lines is generated. The sum of these chaotic direction and force vectors at the end of the In Line element always goes to zero according to the rules of classical physics. In this way, it is possible to break up field-effect interferences that were previously still present, and to clean up the signal.

This principle can be applied to the loudspeaker line, as well as to the signal path with RCA and XLR connectors, and even to the mains line in the high current range. Since the In Lines are elements to be interconnected, the choice of material also changes the sound. The sonically optimal choice can be made with the In Lines in the signal path between the materials silver and gold, whereby no weighting of better or worse is to be made by the material. Both materials have different sonic properties, which must fit the entirety of the HiFi chain.

However, the In Line in the supply line is also available in a Signature version, which performs a special optimization of the resonance and natural vibration behavior down to the molecular structure of the conductors within the power cord.
