Product Description:

The Douk Audio G4 Mini is a versatile and powerful mono channel digital power amplifier designed to elevate your audio experience. Whether you're looking to enhance your subwoofer or full-frequency speakers, the G4's B/M switch allows you to connect to different speakers and adapt to various audio setups.
With dual NE5532 op-amps and a TI TPA3116 chip, the G4 offers a robust 100W of output power, making it suitable for passive 3-10 inch full-frequency speakers or 4-12 inch subwoofers. Experience cinema-quality sound as you upgrade your 2.0 channel audio system to a 2.1 channel setup with the G4.
The G4's unique design involves combining stereo (left and right channel) inputs for initial signal analysis and frequency processing before power amplification. This process results in purer low-frequency filtering and more efficient power consumption, providing you with a clearer, more dynamic sound.
Despite its mini size, the G4 doesn't compromise on quality or performance. The solid aluminum chassis not only adds to its sleek appearance but also contributes to its durability, making it a fashionable and long-lasting addition to any HiFi home or desktop audio system.
For those seeking a stereo output, the G4 is available as a mono channel amplifier. To achieve a true stereo sound experience, you may purchase two or three G4 units and configure them to drive your audio system independently. Upgrade your audio setup with the Douk Audio G4 Mini and immerse yourself in the rich, powerful sound you've been missing.
