Fitted with a Texas Instruments Incorporated TPA3118 Class D amplifier chip, this mini amp produces efficient audio, with extremely low distortion, and it runs cool while doing it. A 12 VDC, 3A power supply is included with this amp, which is ample power to drive almost any speaker. But one amazing feature of the LP-2020TI is its ability to run on a wide range of voltages; 4.5-24 VDC. That means you can run this amp in a portable application using only 3 AA batteries or you can upgrade your power supply to maximize its full potential.
All the features you needSimple and straightforward, this amp is easy to use. To get started, just plug in your power supply, connect speaker wire between your speakers and the spring loaded terminals on the back panel, connect a source device using either the 3.5 mm AUX input or stereo RCA jacks, turn it on and rock out. Customize your sound using the bass and treble controls or push the "Direct" button to bypass this circuit for a more pure listening experience. The oversized front knob controls the volume smoothly and is encircled by an array of blue light. Mounting tabs on the sides of this amp make it easy to securely mount this amp into turnkey DIY projects. Enjoy great sounding, easy-to-operate audio and more features than you would expect in an amp in this price range with the Lepai LP2020TI.

Please Note: The included power supply is capable of driving this amp at 2 x 15 watts per channel. To realize the full potential of this amp (>20 watts per channel), we recommend a power supply 15 to 19.5 VDC, 3A (minimum) that is capable of producing up to 60 watts of total output. Make sure both speaker output channels are hooked up to a speaker when in operation.
Developing this amplifier, the Lepai engineers knew they had to design an amp that combined efficiency, sound quality, and value — and they did it. Focusing their design around the TPA3118 amp chip, they created the LP-2020TI. This amplifier from Lepai overcomes the competition in both flexibility and performance. With standard features like short circuit and thermal protection, this amp requires no special knowledge to operate. In fact, it will run on 4.5V - 24V DC expanding the possibilities of project integration. Whether you want to use the Lepai LP-2020TI in a low-voltage portable audio project or use it to drive a set of tower speakers, this little amp is up to the challenge.
