SHORT ABOUT MATRIX 1.4

MATRIX 1.4 is free & open audio power amplifier platform. This is open hardware technology which is developed and freely provided to aid the people in producing audio power amplifier KIT without counterfeiting, without piracy, or without breaking the copyright law.

THE NAME OF "MATRIX 1.4"

The former name of MATRIX 1.4 is "FORMULA 1.4", which is renamed into MATRIX 1.4 at the year of 2005 to avoid the similarity over a sport-car championship's name known as "FORMULA 1". The name of "MATRIX" in MATRIX 1.4 is not similar to Matrix Power Amplifier from England, not even a part of any other platforms. MATRIX 1.4 is MATRIX 1.4, the name was written in UPER CASE of letters and combined with space and closed by the decimal-floating number of 1.4.

THE HISTORY LOG OF MATRIX 1.4 DEVELOPMENT

THE ORIGIN OF MATRIX 1.4

The origin of MATRIX 1.4 schematics are known as "i-variant" and "R" (rework release), that originally developed based the pure MATRIX 1.4 formula by Heru Himawan Tejo Laksono, Mujiono Irkhas, Sangidhin, & Dargo. The pure MATRIX 1.4 formula applies ultra-gain amplification model, short bandwidth, and capable only for considered-low-voltage operation (lower than 100V), under the consideration for the simplistic of circuit-system modeling and to guaranty the function stability. However, it is not a best choice for everyone, in case that the pure MATRIX 1.4 references the noisy character due the ultra-gain amplification model (noise is very small, but still audible on idle state if you close your ear over the tweeter-loudspeaker that operated with MATRIX 1.4). The ultra-gain amplification model also causes the problematic of fault PCB-grounding such hums and parasitic-oscillation, so that it must be applied with specific grounding method between input, output, and the circuit of power supply unit. With the short bandwidth amplification model, the origin models of MATRIX 1.4 can be operating more stable, especially to prevent the NFB-lag parasitic-oscillations and capacitive-loads of long-parallel of loudspeaker-cable. Still, I (Heru, the author of original MATRIX 1.4) notes for you, that MATRIX 1.4 may be not a best choice, but it will be a good fella for your hobby.

R-2 RELEASE

R-2 or R2 is one of origin MATRIX 1.4 variants, developed by Heru Himawan T, Mr. Mujiono Irkhas, Mr. Wawan "Dongqyu" Noviayanto, Mr. Agung, Mr. Kuswanto "Regest", and more at the City of Purwokerto - Central Java - Indonesia. This variant is one of the most and widely used since the year of 2010. Some customized versions of R2 also released by the MATRIX 1.4 community under direction of Mr. Robert Tombilangi (Kawanuwa & WS Variant Developer).

PROGRESSIVE MODEL VARIANTS OF MATRIX 1.4

MATRIX 1.4 also developed into the progressive enhanced models, such RLVA, FH (Free Hand, a modified of RLVA), and DOS-V/DOS-VAS (Dynamic output sinking VAS). These models are purposed to improve the output-damping factor and output precision.

BACKWARD COMPATIBILITY MODEL VARIANTS

The backward compatibility model is popularly known as "BC-i". This is a backward model to i-variant in fusion with R-2. Some other variants of backward-compatibility are so called as Kawanuwa and "WS" (Wiro Sableng) that developed by Mr. Robert Tombilangi. Kawanuwa is based the R-2, and WS is based BC-i.

PERSONAL CUSTOMIZED MODEL VARIANTS

There were some personal customized variants such as M + ANDALAS by Mr. Andi Rithonga (Andi Lala), SILUMAN + MAGNUM & SENUSA By Mr. Eric Tindaon & Mr. Damanhuri Dalimunte, EVOLUTION by Mr. V. Sianipar and many others.

FORK PLATFORMS BASED MATRIX 1.4

FG PLATFORM

FG PLATFORM is an earlier fork of MATRIX 1.4. The development was totally discontinued.

FPA GPL

FPA GPL is a fork of MATRIX 1.4. It contains some formula of MATRIX 1.4. The developer of FPA GPL never decide to use the name of MATRIX 1.4 in the principal to avoid the dualism. The development seemed not active anymore though its publication site still online.

THE NEXT GENERATION OF MATRIX 1.4: "MATRIX 1.4 II T13"

MATRIX 1.4 II T13 or known as "T13" is a fusion of the origin of MATRIX 1.4 and F23 AUDIO POWER AMPLIFIER TECHNOLOGY PLATFORM, a reformulation for improvements to gain better application performances and to simplify the core circuit model. While F23 designated to apply complex circuit model (to guaranty precision), MATRIX 1.4 II T13 designated for simplicity and for who wants to do more handy customization. T13 implements TEF (Tripple Emitter Follower) output-stage, but without the need of symmetrical sub-circuit model. T13 implements modern formulation, normal-gain amplification model and large bandwidth amplification. More information of T13 are available at the official site of MATRIX 1.4 II T13 at http://matrix-1-4-two-t13.sourceforge.io/.

NOTES FROM ORIGINAL AUTHOR TO CLEAR THE MATRIX 1.4 LICENSING MODEL

As of the year of 2017, I am herein, the original author of MATRIX 1.4 (Heru Himawan T) no longer supporting the corporation with any commercial variant developers. I put MATRIX 1.4 back into an open hardware technology as just in beginning. All schematics of MATRIX 1.4 must be openly published on the public site under the terms of general public license such as GNU GPL (preferably GPL V.3 or any later versions) or perhaps BSDL (preferably Clause-3 of BSD License). It is clear, I totally put MATRIX 1.4 back as it ought be: "an open hardware technology".

If someone wants to develop a NON-FREE or private schematic that she/he claimed as a MATRIX 1.4 schematic, I NOTE herein to him/her to not use any label or logo of MATRIX 1.4. Developing a NON-FREE schematic under the name/label/logo MATRIX 1.4 is a violation against the MATRIX 1.4 licensing model today and for the future. I also note herein, MATRIX 1.4 logo or label shall not be used to name a non-MATRIX 1.4 variant schematic.

If someone wants to develop MATRIX 1.4 and wants to claim his/her self as "a developer of MATRIX 1.4 variant", he/she must be ready to follow the MATRIX 1.4 guidelines and understands about "freedom in civilization", and if not, so just don't ever try to involve in MATRIX 1.4 development and don't claim self as a MATRIX 1.4 developer.

DEVELOPMENT GUIDELINES

The following guidelines must be applied for the personal or work-team/group-of-developer of MATRIX 1.4 variant.

If yourself as a single person cannot fulfill all the conditions or not able to conduct all works in developing a MATRIX 1.4 variant, so you must organize a work-team for working together. You shall not always be a single fighter.
