Описание товара






Amplifier with the highest characteristics and the best in the class of power density.
Dual internal error correction technology is now integrated into the X-series amplifiers. Input signal is analyzed, compared and corrected twice. By facilitating the topology of the Alpine circuit, the output signal is as clear as possible. As a result, at the output from the amplifier you have a signal with the widest frequency response, which not only complies with the Hi-Res audio 40 kHz standard, but even expanded to 60 60 which gives a higher attenuation rate and the lowest noise level.
Small dimensions.
Digital technology X-series is highly effective, so the amplifiers are more compact, which means they are easier to install in the car.
Ultra-wide amplitude-frequency response.
Ultra-wide X-series amplifiers, without analogs on the market, allows listeners to get excellent sound quality and detail, superior to the best audio devices.
Unique cooling system.
The chassis of the X-series amplifiers is based on an aluminum radiator, which provides cooling of the amplifier when operating in peak modes. Excess heat is removed from the amplifier through a new radiator profile that improves air flow and increases surface cooling area. Channels without a fan located on both sides of the amplifier, provide convection air flow: Hot Air, rises from the top of the amplifier, which forms a vacuum that sucks. This intelligent design provides thermal thermoregulation for continuous listening.
Installation and connection.
We completely recycled the connectors of the speakers and power connectors: The new removable connectors have small losses and are able to pass the current of great power. You can use cables up to 25 mm²-your amplifier will be provided with the energy it needs, while installation and connection are very simple.
Remote bass level controller (rux-knob2).
If you complement your amplifier with a rux-knob2 regulator (sold separately), you will get the possibility of operational control directly from the dashboard. Compatible with models: x-a90m, x-a70f (3 Kan + 4 Kan bridge connection) and x-a90v (5 Kan).
Controls and settings are located on top.
Simply remove the top decorative cover and you will get access to all controls necessary to adjust the amplifier.
