Featuring advanced GuardRail protection, a subwoofer/satellite crossover, and compatibility with popular 4Ω and 8Ω speakers, it delivers clean, distortion-free audio with easy setup and durable construction. ## Description GX Series amplifiers are ideal for professional entertainers who require maximum performance and portability on a limited budget. QSC designers, headed by Pat Quilter, have optimized output and appearance while reducing raw material cost and weight. It's all here dramatic styling, easy hookup and adjustments, excellent audio quality and QSC reliability. GX amplifiers deliver just the right amount of power to the most popular speakers used by entertainers. Most loudspeaker manufacturers recommend an amplifier with power output equal to the speaker's "Program (Music) Power" rating or two times (2 x) the "Continuous (RMS) Power" rating. The GX3 is ideal for speakers in the 300 watt (Program) range, supplying maximum possible power to 4 ohm and 8 ohm loads.Technical NotesThe GX3 uses the latest evolution of the QSC Grounded Collector output system, for optimum cooling of the critical power transistors. A true Class B biasing system combines maximum thermal efficiency with excellent audio performance. GuardRailGuardRail protection delivers full peak power while preventing detrimental overloads. During excessive clipping, or extreme overheating, GuardRail reduces gain just enough to preserve the integrity of the music, protect the speakers and keep the audience excited, without unprofessional distortion levels or shutdowns. Subwoofer/Satellite Crossover A subwoofer reduces strain on the full-range speaker, allowing it to play louder, or letting a smaller speaker do the same job. The GX Series supports this mode with a Crossover switch that splits the full-range input entering Ch 1, sending 20 Hz - 100 Hz to the sub (Ch 1) and 100 Hz - 20 kHz to the top box (Ch 2). The front panel gain controls balance the sub and top box, while GuardRail optimizes peak power into the sub and top individually, for greater musical impact and dynamic range.Features:Power levels matched to the most popular speakers used by entertainers Optimized for maxi... Review: Strong, powerful and light. - It can handle anything that comes to it. Every since I sold my bass heads and bought this I haven't turned back since. It works in any situation audio wise. It will work for a DJ, PA system, guitar rig or a bass rig just to name a few. It can easily power any cabinet without strain. I run a 15-inch bass cabinet as of now and I have to be careful of not blowing my cabinet up! This thing actually is built strong! You can't go wrong with QSC, it is the best! Review: Nice power amplifier - The cost was the main reason for the purchase, however, I didn't know a enough about the manufacture and I read some reviews. Although some were helpful, I am glad I made the purchase. So far this amplifier is on point and it sounds awesome with Pyle mixer and Mackie speakers. ## Features - I/O Designed for Contemporary Applications - Product Type: Sound and Recording Equipment - Package Quantity: 1 - Country Of Origin: China - Positive/negative binding posts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0018D63KO | | Best Sellers Rank | #84,429 in Musical Instruments ( See Top 100 in Musical Instruments ) #339 in Power Amplifiers | | Brand | QSC | | Customer Reviews | 4.3 out of 5 stars 96 Reviews | | Item Type Name | A-B Box | | Item Weight | 12.1 Kilograms | | Manufacturer | QSC | | Mfr Part Number | GX3 | | Model Number | GX3 | | Unit Count | 1.0 Count | | Warranty Description | 1 year. | ## Product Details - **Item dimensions L x W x H:** 16 x 19 x 4 inches - **Manufacturer:** QSC - **Maximum Supply Voltage:** 230 Volts - **Minimum Supply Voltage:** 120 Volts - **Voltage:** 230 Volts ## Images ![GX3 300-Watt Power Amplifier - Image 1](https://m.media-amazon.com/images/I/51ONjJMUKLL.jpg) ## Questions & Answers **Q: hi.can you take a line out of this to chain this to another amplifier ??** A: Hello. I don't think you can. This is a power amp and it is different than a bass amp or guitar amps that have waist chain options. You can run a speaker cab that has a output on it. For example..You run a non-powered PA cabinet with this and that cabinet has an output where you can disperse the power to that cabinet and another cabinet. You can do that only because of the speakers but this amp cannot do a chain of any sort. **Q: Is this claimed 300 watts peak or rms? also is this into 8 ohms, 4 ohms, etc. and is this power per channel or total output?** A: 300W PROGRAM PER CHANNEL, into an 8 ohm load. 425W PROGRAM PER CHANNEL into 4 ohms. Wattage runs higher if only one channel is driven. All watts are rated at PROGRAM. Expect RMS to be about 50-100W more. **Q: Can you have two pairs of speakers connected to this thing?** A: Two pairs of 8 ohm speakers..yes..each channel can play up to 4 ohm load.. Which is two 8 ohm speaker connect in parralel.. Per side.. Or four 8 ohm to a amp.. Or connect 2. X4 ohm in series to side to give 8 ohm per side **Q: Does this amps have automatic trigger to be use with a ht processor ? i'm thinking no, as it's a pro amps but asking anyways..thanks** A: Hi, if you mean off/on with the receiver, then no. Or at least I saw none on the back. I use it with my 2 channel receiver and turn it off separately. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Strong, powerful and light. *by D***. on November 18, 2014* It can handle anything that comes to it.
