Review: Excelente para convertir un subwoofer pasivo en activo. - Tenía un equipo de sonido Onkyo con subwoofer pasivo, hace poco lo reemplacé por uno nuevo que sólo tiene salida para subwoofer activo, mi subwoofer anterior aún servía, así que decidí comprar este adaptador y funcionó a la perfección. ## 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. - Notice: this is mono amplifier, if you want stereo output please buy 2PCS or 3PCS. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B081Q3VZ9V | | Brand | Douk Audio | | Brand Name | Douk Audio | | Customer Reviews | 4.3 out of 5 stars 163 Reviews | | Included Components | 1*G4 Mono Amplifier; 1*19V Power Supply; 1*Manual | | Item Weight | 240 Grams | | Manufacturer | Douk Audio | | Material Type | aluminum | | Maximum Supply Voltage | 24 Volts (DC) | | Maximum supply voltage | 24 Volts (DC) | | Minimum Supply Voltage | 12 Volts | | Minimum supply voltage | 12 Volts | | Model | DZ078_US | | Mounting Type | Freestanding | | Mounting type | Freestanding | | Number of Channels | 1 | | Output Power | 100 Watts | | Package Type Name | box | | Specification Met | Technical Specifications Met | | Supply Current | 4.74 Amps | | Voltage | 12 Volts (DC) | ## Product Details - **Manufacturer:** Douk Audio - **Maximum supply voltage:** 24 Volts (DC) - **Minimum supply voltage:** 12 Volts - **Mounting type:** Freestanding - **Voltage:** 12 Volts (DC) ## Images ![Douk Audio G4 - Image 1](https://m.media-amazon.com/images/I/51VANpJLHiS.jpg) ## Questions & Answers **Q: Can anybody tell me definitively--no guessing please--that the aux input is stereo? Is it only inputting one channel (left or right), or summing them?** A: The system is just giving you a mono signal the subwoofer output on your receiver is just a mono signal unless you have a right and left output. I have never heard of right and left output before for a subwoofer, but I guess there is always a possibility. **Q: Is this a good choice for a center channel speaker?** A: It may work for you, depending on your speaker, the amp on other speakers, the other speakers, your set up (assuming you have something to feed a distinct center channel) and your room. I wouldn't. How many volume controls do you want to get up and mess with? If you're trying for a home theater setup, you'll be happier with Amazon's entry level Onkyo 5.2 system at $329. Use the speakers you have and upgrade as you can afford. On the other hand if this is a dorm room, go for it. **Q: I have a powered subwoofer but need to combine left and right channels with a cross. will this conflict with my powered sub?** A: probably not a good fit with a powered sub unless you are replacing the amp in that sub. **Q: can it handle a 12 inch sub 200watts?** A: It can drive the speaker, but how well will depend on the efficiency of the speaker and not just the size and watts it can handle. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent little sub amplifier!!! *by A***M on 20 August 2024* ### ⭐⭐⭐⭐⭐ Excelente para convertir un subwoofer pasivo en activo. *by O***P on 27 October 2024* Tenía un equipo de sonido Onkyo con subwoofer pasivo, hace poco lo reemplacé por uno nuevo que sólo tiene salida para subwoofer activo, mi subwoofer anterior aún servía, así que decidí comprar este adaptador y funcionó a la perfección. ### ⭐⭐⭐⭐⭐ Wow!
