Alpine X-A90V – 4-channel + Mono Power Amplifier
Alpine introduces the all-new X-Series of high-grade speakers and amplifiers. These products have been engineered and tuned to create a perfect match for extraordinarily dynamic, realistic sound reproduction and a spatial sound impression.
The all-new X-Series amplifiers set a new standard for sound quality performance and power output in a very compact design. Available in mono, four channel and five channel configuration, these amps are a perfect match for the all-new X-Series speakers and subwoofers.
Product Info
HIGH PERFORMANCE WHILE RETAINING CLASS-LEADING POWER DENSITY
X-Series amplifiers are built on a new Alpine-proprietary circuit design that achieves class-leading power density and reliability while performing at the top of its class. By simplifying the circuit topology, Alpine is able to ensure the cleanest possible signal path. While the simplicity of the circuit contributes to a great sounding signal, we added an exclusive dual feedback loop that corrects signal distortion. This clever design results in a frequency response that not only meets the Hi-Res audio standard of 40kHz but even extends up to 60kHz. The amp maintains a very low phase shift throughout the music spectrum, which allows your music stay faithful to the original recording with realism that puts you in the centre of the performance.
All Digital Design
Compact and Powerful: the new digital amplification circuit allows very high power output while keeping a small footprint.
Sound Quality Performance
The new X-Series amps are designed for true Hi-Res Audio playback, featuring ultra-low distortion and a wide frequency range.
Thermal Management
At the core of the X-Series Amplifier’s chassis is a solid cast aluminium heat sink, which keeps the amplifier cool when performing at its peak power levels. Excess heat is removed from the amplifier through the newly designed heat sink profile, which both improves airflow and increases surface cooling area. The fan-less channels located on both sides of the amp allow for convection flow of air; hot air naturally rises out from the top of the amplifier, which causes a vacuum that sucks in cool air from below. This smart design allows for continuous thermal control for an uninterrupted listening experience.
Smart Installation
We fully redesigned the speaker and power supply terminal connectors: the very compact design allows clean and simple installation with lossless connectivity. Includes High Level Input with automatic power on.
Subwoofer Level Control
Get the RUX-KNOB2 to control the subwoofer level output right from the dashboard. This controller is compatible with the X-A90M, X-A70F (3Ch+4Ch bridge mode) and the X-A90V (5Ch).
Adjustment Panel
Remove the aluminium top cover plate to reveal the amplifiers control panel. It allows easy access of all adjustments while the amplifier is installed.
