AK50 2.0 Channel Amplifier

The AK50 is a 2.0 channel stereo amplifier rated at 400W peak power per channel with a continuous output of 50W per channel into 4-16 ohm passive speakers. It integrates Bluetooth 5.0, FM radio, USB, SD and AUX inputs plus a microphone input with echo control for karaoke or announcements. A subwoofer output allows system expansion.

Check speaker impedance and input sources

Verify that your passive speakers present a 4-16 ohm load to match the amplifier specification. Ensure you have source devices compatible with Bluetooth 5.0, USB, SD card, AUX or FM radio. The unit includes a remote control for mode selection and volume adjustment from a distance.

Fits a compact stereo or karaoke setup

The amplifier drives two passive speakers directly and adds an active subwoofer output for deeper bass. Bluetooth 5.0 provides wireless streaming up to 15m in open areas. Microphone input and output with independent echo adjustment support live vocal use without needing a separate mixer.

Questions about this item

What comes in the box with the AK50 and what must I buy separately?

The package includes the amplifier and a remote control. You will need to purchase passive speakers rated 4-16 ohms and speaker wire separately.

Should I choose the 400 W peak figure or the 50 W per channel rating for my speakers?

The 50 W per channel continuous rating is the figure to match with your speakers; the 400 W value is a peak number only.

What does the 0.4 % distortion figure mean when I am listening at normal volume?

It means the amplifier adds very little colouration, so music sounds clean and faithful to the original recording at typical listening levels.
