3 reviews

Features

G4 can be used as full frequency amp or subwoofer amp with the B/M switch to connect different speakers, and with 3.5mm AUX and RCA input to compatible with different audio devices. 2PCS G4 can be used to drive left and right channel independently to avoid mutual interference.
Adopting 2PCS NE5532 op-amp and TI's TPA3116 chip, output power up to 100W enough to drive passive 3-10 inch full-frequency speakers or 4-12 inch subwoofers, no audible noise even at large power output, upgrade your 2.0 channel audio system to 2.1, providing shocking cinema effects.
By combining the stereo(left and right channel) input, first to do signal analysis and frequency processing and then power amplification, the low-frequency filtering will be more pure and power consumption is more efficient.
Mini size with exquisite appearance: mono integrated class D amplifier, simple compact design but with powerful function, more fashionable and durable solid aluminum chassis, very suitable for HiFi home and desktop audio system use.
