Joengoep AK50 400W Home Audio Amplifier

The Joengoep AK50 is a compact 2.0-channel home audio amplifier that delivers up to 400W total power, Bluetooth 5.0 streaming, mic inputs with echo control, USB/SD playback, FM radio and an active subwoofer output for fuller home sound.

Designed as a central hub for a home stereo or small party setup, the AK50 combines multiple inputs and hands-on tone controls in a metal chassis. It supports passive speakers from 4–16Ω and provides independent bass, treble, master volume and mic controls so you can tune sound for music, movies, karaoke or announcements without extra equipment.

How does the AK50 connect to my devices and speakers?

The AK50 accepts Bluetooth 5.0, USB flash drives, SD cards, FM radio, AUX and microphone inputs, plus it has a dedicated active subwoofer output. Pair phones or tablets wirelessly, plug in a USB stick for MP3 playback, or use wired sources like TVs and DVD players for low-latency audio.

• Bluetooth 5.0 for stable wireless streaming up to ~15m in open space
• USB 2.0 and SD card slot for direct MP3 playback — no phone required
• AUX and RCA inputs for TVs, players, and PCs
• Speaker outputs compatible with 4–16Ω passive speakers and active subwoofer out

What sound control options are available for listening and karaoke?

Onboard knobs let you adjust bass, treble, master volume, mic volume and echo independently so you can shape the mix quickly. Two microphone jacks plus echo control make it easy to run karaoke, podcasts, or live announcements from the same unit.

• Independent bass and treble knobs for fine tonal balance
• Separate mic volume and echo controls for vocal clarity and ambiance
• Dual mic inputs for duets or host-and-presenter setups
• Remote control included for convenient adjustments from across the room

How much power and fidelity does the amplifier deliver for home speakers?

The AK50 is rated at a combined 400W power capacity with a 50W x 2 output configuration supported for a wide range of 4–16Ω passive speakers. It aims for low distortion and a good signal-to-noise ratio to provide clear playback for music and home theater use.

• Rated outputs: 50W per channel (supports typical bookshelf and floorstanding passive speakers)
• HiFi-focused components with ≤0.4% distortion and ~80dB SNR
• Metal chassis for improved durability and heat dissipation
• Active subwoofer output for deeper low-end without overdriving main speakers

Can the AK50 handle parties, home theater, or multi-room use?

Yes — the unit’s multiple inputs and mic features make it versatile for small parties, home theater setups, and casual public-address needs. While not a professional concert amp, it’s suited to living rooms, backyards (with weather-appropriate speakers), and small venue gatherings when paired with the right speakers.

• Bluetooth and USB/SD let you play playlists without a computer
• Mic inputs with echo for karaoke, hosting, or announcements
• Compatible with TVs, gaming consoles and media players for video soundtracks
• Remote for easy control during events or movie nights

Who is this for? The Joengoep AK50 is aimed at homeowners and renters who want a single, affordable amplifier to power passive home speakers while adding wireless streaming, USB/SD playback and karaoke-style mic mixing. It’s a practical choice for people building a compact stereo system, hosting small gatherings, or adding richer audio to a TV or gaming setup without complex AV racks.
