QSC Gives European Debut to GX Series
To coincide with their 40th anniversary year, QSC Audio Products have launched their new GX series amplifiers. These will receive their European debut at next month’s Pro Light+Sound expo in Frankfurt, in Hall #8, C16.
These new versatile GX Series amplifiers are taking aim at the needs of musicians, DJs, and performers of all description. Consisting of two professional models outfitted with feature sets and power ratings designed to meet the requirements of popular passive loudspeakers, the GX Series is highly reliable and is marked by affordable prices that suit virtually any budget.
At 8 ohms, the GX3 and GX5 are rated at 300 and 500 watts respectively, offering the continuous power capacity needed for a majority of common passive loudspeakers in use today. Outfitted with roughly twice the continuous power capacity required by the top-selling non-powered loudspeakers on the market, the GX Series is the simplest and best answer to the question “what power amp do I need?”
Both GX amplifiers are equipped with all the input and output connectors needed for compatibility with virtually any source, loudspeaker, or wiring scheme. The lightweight design of the amps combines with the compact size to make either model easy to move or mount within small, portable racks. Just as easy to use, both the GX3 and GX5 feature straightforward user-selectable functions accessed via simple front-panel controls.
Every GX amp leaves the factory with carefully-tuned GuardRail technology that guarantees full, peak power without harmful levels of distortion. As a result, the only way to get serious distortion from a GX amp is by sending distortion into it.
At the heart of the GX Series lie linear toroidal power supplies similar to those used in QSC's popular RMX line of amplifiers. Delivering improved thermal stability and efficiency when compared to a number of other amps in its class, the GX3 employs a Class B output topology that squeezes every watt available from electrical circuits often overburdened by other stage gear.
The two-tier Class H design of the GX5 approximately doubles the power of the GX3 using the same size transformers and heat sinks. Smaller size, lighter weight, and more efficient use of electricity follow, along with more accurate peak performance on a short term basis with reduced loss and less distortion.
A market-driven philosophy guided the development of the GX Series from its inception, with QSC engineers dedicating their efforts to producing a product that addressed how users actually configured their systems. Based upon the results of extensive research, the design team determined that very few potential GX users needed bridged operation or an extremely high output capacity at 2 ohms. By eliminating these capabilities and building the amps primarily for use with 4- and 8-ohm power, the GX Series ultimately emerged with significant cost and size reductions, while still remaining fully-protected into all loads, and supporting light-duty 2-ohm operation for occasions when it might be needed.
The GX Series amps are the smallest in their class at almost half the depth of the competition. They are also the lightest linear amplifiers among competitive offerings (at 25 lbs) and are housed in a rugged chassis with an attractive front panel that brings a professional appearance to any equipment rack.
