Has anyone heard or used Neutral Audio´s DREi technology


Feb 19, 2013
Hello everyone, my name is James from NEUTRAL AUDIO TECHNOLOGIES. I would like to present you with a new audio technology we have designed that enhances the musical reproduction of any amplifiers, speakers and filters obtaining notably better final sound to any sound system.

It is called DREi Technology (Dynamic Reduction of Electronic Interactions) whose application is anywhere when a clearer brighter purer sound is required, in PA as well as studios, in line and always before amplification. DREi is totally analogue.

This technology is inserted into all of our models and we also have a module for OEM, that can be inserted into others audio designs.
It works by attenuating electronic intermodulation and in between frequencies (Deintermodulator), it processes the form of the sound waves, and so only amplifying the sinu waves that are sutiable for filters and speakers.
Our models also include a fine control over the answer of its soundstage in order for it to adapt to any sound systems and playing environments.

I invite you to have a look at our website www.neutralaudio.com for more information and from this forum would be more than delighted to answer any questions and to talk to you more about it..

What is DREi?

DREi reinterprets the waveforms:

A speaker is fully efficient when it comes to reproducing sinusoidal waveforms. DREi reinterprets the signals to be as similar to sinusoidal as possible, limiting the amplification of waveforms unsuitable for the speakers. Passive filters in the speakers also tend to respond worse with square or triangular signals, especially the capacitors and coils. At no instant any information is lost, only redefined, and so the total final energy is the same as the original.

DREi is a DeIntermodulator:

Harmonic Distortion Neutralizer. Daily engineers and technicians work to reduce the inevitable intermodulation that occurs in the electrical signal that flows through the electronic components and impairing the purity, the three-dimensionality and the finished musical quality. They also use various tools to minimize the intermodulation of the nearest frequencies. DREi attenuates both modes of intermodulation, becoming a powerful tool for optimum sound.

DREi adjust the soundstage:

Using a new topology of amplification, DREi dynamically controls multiple buffers or preamps for a stereophonic signal. This enables the user to adjust the end soundstage by controlling these buffers and obtaining the best response in conjunction of the amplification, speakers and listening position. It is not an equalizer, and does not produce audio artifacts. The frequency response is affected depending on the chosen position to align the associated system. The user can disable these sound stage modes, but the DREi process will always be run at 100%.

· Strong, powerful and detailed bass
· Very present and extremely clear treble and midrange
· Clearly defined soundscape and background
· Clear air and audible reverb tails
· Eases mixes in the professional sector
· Better sound diffusion in live concerts
· Eases tone in the in-ears for artists
· And more ...

· Enhances the overall sound quality of the system of which it is installed. More efficiency and better performance.

· Corrects errors produced by the electronics due to tolerances that can add up.

· Small musical details that may be hidden by the interactions of electric circuits appear with unusual force and cadence.

· The timbres and nuances of the voices and instruments are more present and harmonious.

· Clarifies orchestral and choral masses, affected by digital circuits used in recording and playback and which are masked by the other instruments.

· Controls the total energy of the signal to be amplified preventing energy being taken by other frequencies.

The music flows smoothly, neutrally and with crystalline transparency

· You get more natural clean and accurate sounds
· The dynamics are increased
· Real and defined voices with full integrity
· Greater channel separation
· High dimensionality and distinction of sound levels and layers
· Increased openness
· Minimizes acoustical problems in rooms
· Increases the sound pressure with the same system
Test a DeIntermodulator in a real situation. You can personally check that does what we say.

Mitigate the harmful INTERMODULATION that occurs between two or more signals with different frequencies (or instruments). They occur in all the elements that make up an audio playback system and impairs the purity of the original musical signal.
