The Rockville BLUAMP 90 is a compact stereo amplifier that doubles as a home audio hub. It pairs Bluetooth streaming with a phono/aux RCA input, optical and HDMI ARC inputs, USB and SD playback, and two mic inputs with echo for karaoke. Rockville rates it at 100 watts RMS continuous and 400 watts peak, enough for bookshelf, ceiling or tower speakers. It suits budget buyers who want many inputs in one box; dedicated AV receivers offer room correction and more channels, but cost more and are bulkier.

The Rockville BLUAMP 90 is a Bluetooth stereo amplifier for a home stereo or karaoke system. It uses a Class D circuit and a built-in pre-amplifier with low distortion. It is rated at 400 watts peak and 100 watts continuous RMS, enough to drive bookshelf, ceiling, wall-mount or tower speakers.
It accepts several sources: Bluetooth with a 33 foot range, USB and SD card playback, an optical input for digital sources such as a TV, and an HDMI ARC input for a TV's HDMI ARC connection. The RCA input switches between aux and phono, so it can connect a turntable or another analog audio device. One set of RCA outputs connects a subwoofer or another amplifier.
Two 1/4" mic inputs have echo and mic volume controls for karaoke. Bass, treble and master volume controls let you adjust the sound, and an LCD display shows status. The included remote controls all functions.
