Power Old Speakers with One Compact Amplifier: AK35 Pro

Power Old Speakers Without Replacing Them

If you have a pair of passive desktop, bookshelf or TV speakers that still sound good, a compact stereo amplifier may be all you need. The WOOPKER AK35 Pro is a 2.0-channel amplifier with 40W x 2 rated output, Bluetooth, USB and AUX/RCA input, so it can power speakers in a bedroom, home office, living room or garage setup.

What the AK35 Pro offers

• 40W x 2 rated power and 90W x 2 peak power for passive speakers
• 4-16 ohm speaker compatibility for common bookshelf and desktop speakers
• Bluetooth wireless streaming from phones, tablets and computers
• USB and AUX/RCA input for wired sources
• FM radio built in
• One microphone input with a separate mic volume control
• Overall bass, treble and master volume controls
• Remote control included

Desktop and small-room setup

Place the AK35 Pro on a desk or shelf with airflow around it, connect left and right speaker wires with matching polarity, and select the input you want. Start at low volume, then use the master volume and bass or treble controls to tune the sound.

TV and bookshelf speaker setup

For TV sound, connect the TV audio output to AUX/RCA when available, or stream from your phone through Bluetooth. The same setup works with bookshelf speakers in a bedroom or small living room where a full AV receiver is unnecessary.

Using the microphone input

The AK35 Pro uses one MIC input. Use the MIC volume control to set the microphone level separately from the music, and use the overall bass and treble controls to tune the complete output for karaoke, speeches or presentations.

What to check before connecting speakers

• Use passive speakers only; do not connect powered speakers to the speaker outputs
• Keep speaker impedance within the rated 4-16 ohm range
• Turn the amplifier off before connecting or changing speaker wires
• For best results, do not run the amplifier continuously at maximum volume
