As much by its musical performance as by its sleek and luxurious presentation, the X-A1200 amplifier immediately commands respect. A monophonic amplifier is the ideal solution for improving the overall performance of a High-Fidelity system.
The finest performance prohibits any interaction of the supply circuits as well as of the amplifier stages between the left channel and the right channel. The ultimate achievement of this philosophy is to totally separate the two amplifiers completely. The high power supply can be described as “oversized”. This term is not usurped, because of the size of the mono block, its compartmentalized design and its power supply electronics based on a 1 VA toroidal transformer, two power diode bridges mounted on a large heatsink and 12 capacitors of 10,000 μF each - an impressive total of 120,000 μF!
Associated with 10 very high current power transistors (NJW0281G – NJW0302G), this power supply allows the X-A1200 amplifier to deliver a power of 450 Watts RMS at 8 Ohms and more than 700 W RMS at 4Ω.
A switch located at the back of the device allows the X-A1200 to deliver the first Watts in class A (High Bias mode). Beyond this power, the transition to class AB takes place automatically and gradually.
The robust design of the frame makes it rigid, even when the cover is removed. The interior is compartmentalized, which, in addition to increasing rigidity, achieves galvanic isolation between the various sub-assemblies, installed in a very strategic manner.
