Description

The all-new R-A90S is extreme and class-leading in every way. Beneath its sophisticated and bold design, brings a powerhouse of Alpine ingenuity and technical innovation to create an industry first ‘full-system’ 6-Channel Hi-Res compliant power amplifier.

Delivering serious amounts of power, the R-A90S has the capability to power an entire system with a subwoofer, or can be configured to power an array of 3-way high-end speaker systems with precision using the LP/HP/HP-H/BP crossovers. What’s more, power output is staggered with the capability to deliver different levels of power to each channel regardless of the system configuration.

With performance at the highest standard, the R-A90S has a dynamic range of up to 45kHz and a >500 dampening factor to deliver high power output with precision, as well as a superlative high-definition sound experience.
