This allows the R-A90S to effectively function as both a 3-way active amplifier and a 5-channel amplifier by delivering the power you need to the channels where you need it the most. Now you can use one amplifier to either power an active 3-way sound system or use it to power your speakers and subwoofer without the bulk of an additional amplifier.\u003c\/p\u003e\n\u003cp class=\"img_desp\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0444\/5932\/7653\/files\/R-A90S-1_480x480.jpg?v=1600685859\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch4\u003eNext-Level System Builds\u003c\/h4\u003e\n\u003cp\u003eFor the best possible sound experience, 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.\u003c\/p\u003e\n\u003ch4\u003eProper Sound Stage\u003c\/h4\u003e\n\u003cp\u003eThe R-A90S maintains an extremely low phase shift throughout the music spectrum which minimizing audible imperfections in your music and allows your music to stay faithful to the original recording.
