Description
Description
Experience your music in Hi-Res with the versatile R-A90S 6-Channel Amplifier for hair-raising details that puts you in the center of the performance.
With double the power on the last two channels, the R-A90S’s 5th and 6th channels can be bridged to provide up to 500-watts at 4Ω to a subwoofer system such as a pair of S-SB12Vs.
When you’re ready to upgrade your Alpine system, use the R-A90S to amplify a 3-way active system with enough mid-bass power to create the up-front bass impact you crave.
With incredibly low phase shift and hi-resolution frequency response, the R-A90S can reproduce sound with incredible accuracy that stays true to the artist’s intention.
The R-A90S has dual "Sierra" post-filter feedback loop that correct signal distortion by making the output as close as possible to the original input for accurate sound reproduction.
Use the built-in bandpass, high pass, or low pass filter to individually power each component in your sound system and assign frequency bands for accurate and reliable sound reproduction.
The KTA-200M has input capability to add the optional RUX-H01 Remote Bass Control Knob for quick bass adjustments when needed.
