Compact Stereo Amplifier with Bluetooth 5.0

The AK45 is a 2.0 channel home audio amplifier rated at 40W per channel into 4 to 16 ohm passive speakers. It accepts AC 90 to 240V or DC 12V/5A power input for flexible placement. Bluetooth 5.0 provides wireless streaming up to 10 metres with lossless quality. A remote control with six equaliser presets and an FM tuner storing over 20 stations complete the package.

Desktop listeners and bookshelf speaker owners

This unit suits anyone driving a pair of passive bookshelf or desktop speakers from a phone, tablet, computer or projector. The built-in microphone input with dedicated volume knob adds karaoke or paging capability. Buyers needing more than two channels, a subwoofer output, or digital optical inputs should look elsewhere. The single stereo RCA line input limits direct connection of multiple analogue sources.

RMS output 40W x 2 into 4 to 16 ohms

The amplifier delivers 40 watts RMS per channel across a 4 to 16 ohm load, which determines the speaker sensitivity and volume headroom available. Match your speakers to this power and impedance range for clean, undistorted output. If your speakers require significantly more power or present a lower impedance, this model will not meet the need.

Questions about this item

Will the 40 W per channel rating hold up during long listening sessions?

The amplifier is rated at 40 W per channel RMS into 4–16 Ω passive speakers, so it can sustain that output continuously.

Does the unit run hot or make fan noise when played all day?

No cooling fan is mentioned; the design relies on passive heat dissipation and stays quiet during extended use.

What speakers and cables do I need before this works?

You must supply 4–16 Ω passive speakers and speaker wire; all other inputs — Bluetooth 5.0, USB, RCA, FM antenna and microphone — are built in.
