A Powerful, Customizable 2.1 Amp – Perfect for Studio & DIY Audio Setups!
I bought this ZK-TB21 2.1 channel amplifier module to build a custom audio setup combining my Audio Arrays studio monitors and a 8" 150W subwoofer, and I must say — this little board exceeded expectations!🔧 Power & SetupI powered it using a standard PC PSU (12V rail) via a DC barrel jack with a terminal block adapter. Just make sure to connect the yellow 12V and black GND wires properly — it worked like a charm once powered on!🎛️ Subwoofer IntegrationThe Subwoofer Frequency knob is a real game-changer. I set it around 70–80 Hz to let the sub handle only the deep bass, while my studio monitors take care of mids and highs. This avoided the common issue of muddy or boomy bass — the sound is now clean and well-balanced.🎚️ Fine Tuning OptionsIt has separate knobs for Sub Volume, Treble, Bass, and Main Volume, which gave me full control over my sound. I kept treble and bass flat since my studio monitors already offer accurate output.🔗 Connection SimplicityI used an AUX splitter to feed the same signal to the amp and my monitors. It’s a very easy and effective setup for casual listening or even light production work. No signal loss or distortion noticed.✅ Pros:Compact but powerful — easily runs a sub and full-range speakersGreat tuning flexibility with separate controlsAffordable way to build a Bluetooth, AUX & USB -ready 2.1 audio systemPerfect for studio monitor + subwoofer setups⚠️ Things to Know:Requires a 12V–24V power source with enough amperage (I used a PC PSU)

Great amplifier. Works well with 14 volt adapter also. Sound on bluetooth is not so good. But overall a great product.Update: I have a Panasonic SA-AK122 Music player. I connected speakers of this Panasonic music system to ZK-TB21 amplifier. It sounds great with this little amplifier. Even more clear than Panasonic system.
