Balanced Pure Class A Amplifier ACSS 2x180W 4 Ohm
The Audio-GD Master 3A takes the excellent base of the Master-3, this time in a pure Class A model capable of delivering 2x180W of power at 4 Ohm. This version also offers a slightly smoother and warmer sound signature.
Audio-GD presents us once again the quintessence of technology in audio with this amplifier with a more than neat and clean architecture.
The famous brand of high fidelity audio offers us here an amplifier in the most accomplished form possible with outstanding performances: it delivers 2x90W under 8 Ohm, and 2x 180W under 4 Ohm.
Each product of the brand is scrupulously tested with one of the most powerful systems in the world: the Audio Analysers 2700 Series from Audio Precision.
The brand integrates Linear Fidelity technology to the output circuits and Non Negative Feedback to the amplifier in general. This particular design makes it possible to obtain a linear response curve as well as a very low level of distortion, for a sound restitution of a very great transparency and this whatever the output level and the reproduced frequency.
The Master 3A has 4 analog inputs: 2x XLR and 2x ACSS. The output is of course on 2 speaker terminals, where you just have to plug your speakers to enjoy.
The result is simple: great musicality, thanks to exceptional dynamics and a rich sound that is extremely detailed at all points.
This Master 3A is equipped with no less than 4 transformers including 2 R-Cores for a total of 1600W, 140.000uF of high end Nover capacitors, and 24 high performance ON Semiconductors for the output stage.
This amplifier is also designed around a pure Class A ACSS discrete balanced circuit, with a separate power supply to avoid any interference or electromagnetic disturbances on the signal.
A class A amplifier has the particularity of having all its active components always in conduction. They fully amplify the input signal, thus limiting the harmonic distortion on the output signal. The output signal of the Master 3A is therefore of excellent quality, due to the absence of this famous sinusoidal crossing distortion.
Audio-GD has its own signature technology, called ACSS for "Audio-GD Current System Signal". Thanks to the expertise and the know-how of the firm, this technology offers a less colored, more detailed sound, and of an unequalled neutrality. Each technical engineer of the firm is, in addition to being very experienced, a HiFi and audio enthusiast like you and us. To know, when the ACSS output is used, the XLR and RCA outputs are switched to MUTE.
