WOOPKER AK45 Pro 2.0-Channel 400W Home Stereo Amplifier

The WOOPKER AK45 Pro is a compact 2.0-channel home amplifier that delivers up to 400W peak power with Bluetooth 5.0, USB/SD playback and two mic inputs for music, movies, and casual karaoke.

Small enough to sit on a shelf or desktop, the AK45 Pro combines versatile connectivity with straightforward analog controls. It supports wireless streaming, wired RCA inputs, USB and SD card playback, and two microphone jacks — all wrapped in a compact chassis that’s meant for apartments, garages, and small home theaters. The unit prioritizes clear midrange and controlled bass while giving you manual bass, treble, and master volume knobs for quick tuning.

How does the AK45 Pro connect to my devices?

The amplifier accepts multiple source types so you can use smartphones, computers, TVs, or legacy audio gear. Bluetooth 5.0 enables wireless streaming, while RCA and AUX inputs accommodate TVs, CD players or preamps. For standalone playback, you can plug in a USB stick or SD card.

• Bluetooth 5.0 for stable wireless audio from phones/tablets
• RCA inputs for TV, CD players and external preamps
• USB and SD card slot for direct MP3/WAV playback
• Two mic jacks for live vocal use or karaoke

What sound controls and adjustments are available?

AK45 Pro puts tone shaping and vocal balance on the front panel for fast, tactile adjustments. Separate knobs control mic volume, bass and treble, plus a master volume so you can quickly adapt the sound for music, movies or spoken word. The analogue controls let you dial in warmth or clarity without diving into menus.

• Independent bass and treble knobs for tonal balance
• Microphone volume control with dual mic inputs
• Master volume knob for system-level adjustment
• Remote control included for basic playback and volume (batteries not included)

How powerful is the amp and what speakers work best?

The amplifier provides 50W x 2 RMS rated power with a peak output up to 400W, suitable for bookshelf speakers and small tower speakers in modest-sized rooms. It performs best with speakers rated for similar power handling and impedances the amp supports—typically 4–8 ohms—so you get clear, controlled sound without pushing the amp to distortion.

• Rated output: 50W x 2 RMS (stereo)
• Peak capability up to 400W for dynamic music passages
• Ideal for bookshelf, tower, and compact home theater speakers
• Best paired with 4–8 ohm speakers to maintain clarity

Can I use the AK45 Pro for karaoke or podcasting?

Yes — the front-panel dual mic inputs and independent mic level control make it simple to add vocal performance or live commentary. Plug two microphones directly into the amp and adjust volumes on the fly; USB/SD playback can provide backing tracks without needing a separate player.

• Two microphone jacks for duets or host/guest setups
• Mic volume knob for live level balancing
• USB/SD playback for backing tracks or pod-safe audio files
• RCA/AUX inputs for connecting mixers or other audio sources

Who is this for? The WOOPKER AK45 Pro suits listeners who want a compact, flexible amplifier for small-to-medium rooms: apartment dwellers, casual home theater users, hobby musicians, and hosts who want occasional karaoke or live mic use. It’s a practical choice when you need reliable wireless streaming plus wired inputs and simple tone controls without complicated setup or a large footprint.
