Compact stereo amplifier for passive speakers

The lelisten AK45 is a 2-channel digital amplifier rated at 40W per channel into 4–16 inch passive speakers. It adds Bluetooth 5.0, FM radio, USB 2.0 and SD card playback so you can stream or play local files without a separate source component. The included remote control handles volume, bass and treble from across the room.

Replaces a bulky receiver for near-field listening

Swap a full-size AV receiver for this unit when space is tight and you only need two channels at moderate levels. The jump is worth it in bedrooms, offices or small apartments where a large chassis would dominate the furniture. It is not for buyers who need multi-zone distribution, phono pre-amplification or HDMI switching.

Steady 40W output with basic tone controls

Under continuous music playback the amplifier delivers its rated 40W per channel without a fan, relying on the chassis for heat dissipation. Bass and treble knobs let you shape the response for different genres or room acoustics. Bluetooth range holds to 10 m in open air and 5 m through walls to a TV or PC.
