ARRAROWN AK-380 2.0 CH Amplifier

The ARRAROWN AK-380 is a compact live sound amplifier delivering 40W+40W rated power into 4-16 ohm passive speakers. It suits home listeners, car installations or small venue setups wanting Bluetooth 5.0 streaming plus wired AUX input. The unit includes an LCD display, treble and bass knobs and a remote for convenient control. A 12V 5A power supply is bundled for immediate operation.

Sustained Output and Thermal Behaviour

Rated output sits at 40W per channel while peak figures reach 400W+400W for short transients. The YD7377 chip and advanced circuitry aim to suppress pop and audible noise during Bluetooth pairing. Safe circuit design promotes stable supply voltage and normal heat dissipation during extended sessions. Only the supplied 12V 5A adapter must be used to maintain reliable performance.

Installation Notes and Common Issues

Connections are straightforward: attach passive speakers, plug the included 12V 5A supply and select Bluetooth or AUX via the function key. The amplifier reads U-disk and memory card media directly for plug-and-play playback. FM reception is available using the supplied antenna. Substituting a different power adapter risks unstable operation and is the most frequent setup error.

Questions about this item

Does the 12 V 5 A adapter included with the AK-380 run hot or make fan noise when the amplifier plays at 40 W + 40 W all day?

The AK-380 uses a safe circuit design for stable power and normal heat dissipation with the supplied 12 V 5 A adapter; no fan is mentioned, so operation is silent.

Which passive speakers can I connect directly to the AK-380 without buying a separate amplifier?

Any pair of 4 Ω to 16 Ω passive speakers rated for 40 W per channel will work straight from the AK-380’s speaker terminals.

Can I keep my older TV that only has RCA outputs and still use the AK-380’s Bluetooth 5.0 for phone streaming?

Yes — connect the TV via the AUX input and pair your phone over Bluetooth 5.0; the front-panel function switch selects either source.
