Review: Compact - Good sound easy to use value for money
Review: Amazing! Cannot believe the power! - First things first, this amplifier is tiny but it packs a hell of a punch. With it being no larger than a medium sized hand, you'd never think it'd be able to handle a subwoofer with as little as 2ohms without distorting or overheating. It surely can though. I received this amplifier as a gift, to be used with my passive bose subwoofer. It provides more than enough power at half volume and allows me to adjust the crossover which is perfect. The amplifiers frequency response is also very impressive, it is able to get produce very low bass without distorting or clipping. I also like the fact this can be used as a crossover with powered subwoofers too. I would definately recommend this amplifier. Utterly amazing for the price, it's compact, has great sound quality and looks stylish. Perfect for anyone looking to buy an amp to use with a powerful passive sub or adjust the crossover on an active sub, that's lacking crossover frequency controls.

## Features

- Dual-Purpose PBTL/SUB Switch: Versatile operation allows the G2 PRO to function as either a full-frequency amplifier or a subwoofer amplifier. A dedicated SUB output is specially designed for active subwoofers, with compatibility for both passive and active subwoofers. Additionally, two G2 PRO units can be utilized to independently drive left and right channels, minimizing channel interference.
- High-Power Output Capability: Equipped with a TPA3255D2 amp chip and a robust 32V/5A power supply, the G2 PRO delivers up to 300W, easily driving passive speakers or subwoofers with up to 320W power. It harmonizes well with a variety of speakers, including outdoor, bookshelf, computer, desktop, ceiling, and floor-standing models.
- Premium Design and HiFi Sound Quality: The G2 PRO features a gain switch for two levels of output level adjustment (32/36 dB) and SUB frequency tuning (40-300Hz). It includes a built-in speaker protection circuit and a low-pass filter to ensure noise-free audio even at high power output. Both SUB signal and amp outputs are available simultaneously for an enhanced HiFi listening experience.
- Compact Size with Elegant Aesthetics: This mini-sized, mono integrated class D amplifier boasts a compact design with powerful functionality. The durable, solid aluminum chassis is both fashionable and built to last, making it an ideal choice for HiFi home and desktop audio systems.
- Packing List: 1* G2 PRO Mono Power Amplifier, 1* 32V/5A Power Supply

## Questions & Answers

**Q: Can i use this amp to bypass my knackered active amp ie just usse the shell and connect direct to the speaker?**
A: Yes I bought it to do this myself just had to open the sub and disconnect the plate amp. Used the speaker connections for convenience wired to be a passive sub.

**Q: Can I use this amplifier with active subwoofer only? (Without connecting anything to speaker output?)**
A: No it need a full range speaker and then used with an active sub woofer

**Q: Can this work with tpa3116 amplifier (ns-15g) and nobsound 6j2 vacuum tube preamplifier? i want to add a subwoofer to my hi fi.**
A: as long as your current amplifier has a sub out channel or any such output that can provide a signal such as a tape out.

**Q: Can i connect a 100 w bookshelf speaker and 150w active subwoofer in the full frequency mode ? at the same time ? thx**
A: In full frequency mode the unit is just a straight forward amp and will drive a passive bookshelf as normal. Since you are using an active sub it will tap of the signal going to the bookshelf again as normal.
