Compact stereo amplifier for bookshelf systems

The lelisten AS-22BU pro sound amplifier delivers a maximum of 300Wx2 and an RMS rating of 50W per channel, making it suitable for indoor or outdoor listening. Its small footprint allows it to fit on a bookshelf or inside an A/V cabinet without crowding other components. Upgraded audio processing chips keep distortion and noise low for clear playback.

Bluetooth 5.0 and wired inputs with practical limits

Wireless streaming uses Bluetooth 5.0 and works with phones, tablets and computers. Wired sources connect through two pairs of RCA inputs, a 3.5 mm AUX jack and a USB 2.0 port, while an integrated FM tuner adds broadcast radio. The USB interface is limited to the 2.0 standard, so transfer speeds reflect that specification.

RMS 50W per channel decides speaker matching

The continuous power rating of 50W per channel is the figure that determines whether your speakers will be driven cleanly at the volumes you need. Buyers who require higher sustained output for larger rooms or more demanding loads should look for an amplifier with a greater RMS rating.
