Compact stereo amplifier with Bluetooth 5.0

The lelisten AK45 is a 2.0 channel digital power amplifier rated at 40W per channel into 4-16 ohm passive speakers. It accepts AC 110-240V or DC 12V/5A input and includes treble, bass and microphone volume controls plus a remote for six preset equalisation modes.

Rated 40W per channel with 400W peak headroom

Continuous output sits at 40W x 2 RMS with a distortion rate of 0.5% and signal-to-noise ratio of 85dB. The 400W PMPO peak figure covers short transients, but sustained high-level playback will run into the 40W continuous limit and the 12V/5A DC supply ceiling.

Bluetooth 5.0 wireless input and analogue fallbacks

Bluetooth 5.0 handles wireless streaming from phones or tablets. Wired sources connect via USB, RCA or the microphone jack. The amplifier has no HDMI, optical or network interfaces, so multi-channel home-theatre formats and high-resolution wired digital audio cannot be accommodated.

Questions about this item

Will the AK45 drive my existing 8-ohm passive speakers rated at 40 watts RMS?

The AK45 delivers 40 watts RMS per channel into 4-16 ohm loads, so 8-ohm speakers rated for 40 watts will be matched to the amplifier's rated output.

How can I verify the AK45 is performing to its 0.5% distortion and 85 dB signal-to-noise specifications after setup?

Play a clean test tone at moderate volume and listen for audible hiss or harshness; the low 0.5% distortion and 85 dB signal-to-noise ratio mean background noise should be inaudible and tones should sound pure.

Does the box include speaker wire, a microphone, or batteries for the remote, or must I buy them separately?

The amplifier ships with a US power cord and remote control; speaker wire, a microphone, and remote batteries are not included and must be purchased separately.
