Advance Acoustic
Advance acoustic was formed after the decision was made in Toulouse France, to create a new French brand with an idea which was both simple and audacious: to design audio equipment, reasonably priced but with faultless musical quality. Speakers were the first products off the production line, with 5 models becoming available.
These were an instant success and received high praise from many French magazines. In 2002, Advance Acoustic added electronics to their product catalogue, while keeping the same simple philosophy, reasonably priced without compromising on sound quality.

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

Due to its musical performance and its sober and luxurious appearance, the X-A1200 amplifier immediately demands respect. A monaural amplifier is the ideal solution to improve the overall performance of a HiFi system.

This principle prohibits any interaction between the power supply circuits and the amplifier stages between the left channel and the right channel. The high power supply associated with the "very high current" transistors (NJW0281G - NJW0302G) allows the X-A1200 amplifier to deliver a power of 450 Watts RMS over 8 Ohms and more than 700 W RMS over 4Ω .

Associated with its "Hi Bias" mode of operation, the X-A1200 amplifier will easily power all acoustic speakers on the market. The X-A1200 delivers 450W per channel in Class AB, a switch at the rear of the unit allows the X-A1200 to deliver the first Watts in Class A. Beyond this power, Class AB is done automatically and gradually.
