Advance Paris X-A1200 Mono Power Block

To meet the expectations of the most demanding music lovers who pay particular attention to the final result of their audio system and who devote a large part of their leisure time to listening to music, we have created the monophonic power amplifier X -A1200.

As much by its musical performance as by its sober 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.

Indeed, this principle prohibits any interaction of the supply circuits as well as of the amplifier stages between the left channel and the right channel. 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 000 capacitors of 12 μF each, i.e. 10 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 on 8 Ohms and more than 700 W RMS on 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 open steel 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 rational manner.
