Douk Audio G4 Subwoofer Power Amplifier 100W

Established in 2013, Douk Audio & Nobsound is a brand created by a group of enthusiastic music fans and professional audio experts. Our aim is to "Make Hi-Fi Affordable"! We design and manufacture various audio equipment, including amplifiers, phono preamps, headphone amps, DACs, audio switches, and more.

The Douk Audio G4 is a versatile mono amplifier that can be used as a full-frequency amp or a subwoofer amp, thanks to its B/M switch. It offers 3.5mm AUX and RCA inputs to connect with various audio devices. Using two G4 units allows you to drive left and right channels independently, avoiding mutual interference.

Adopting TI's TPA3116 chip and 2 pcs NE5532 op-amps, the G4 can deliver up to 100W of power, enough to drive passive 3-10 inch full-range speakers or 4-12 inch subwoofers. Even at large power output, there is no audible noise, allowing you to upgrade your 2.0 channel audio system to a 2.1 setup and enjoy cinematic sound effects.

By combining the stereo (left and right channel) input, the G4 first analyzes the signal and processes the frequency, then performs power amplification. This approach ensures more pure low-frequency filtering and efficient power consumption.

Featuring a compact and exquisite design, the G4 is a mono integrated class D amplifier with a fashionable and durable solid aluminum chassis, making it well-suited for HiFi home and desktop audio system use.

Please note that the G4 is a mono amplifier, so if you require stereo output, you will need to purchase 2 or 3 units.
