QSC

Maximum performance and portability with very flexible I/O.

The QSC GX5 Stereo Power Amplifier is 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 of the rackmountable GX5 while reducing raw material cost and weight. The GX5 power amplifier provides full performance for 500 watt (Program) speakers and supplies maximum possible power to 4 ohm and 8 ohm loads. Owners of popular 4 ohm loudspeakers (dual-woofer, two-way models and many subwoofers) will find the 700 watt (4 ohm) power of the GX5 an ideal match.

The GX5 power amp uses a Class H system, based on key elements of the PLX Series, almost doubling power in the same size and weight. QSC design expertise allows the output devices to shift from low-power to high-power rails in less than a millionth of a second, ensuring that the output power is always right where it needs to be without excess loss.

Features

  • Power levels matched to the most popular speakers used by entertainers

  • Lightweight — less than 26 lbs (12.5 kg)

Nice Power Amp

I just got this amp to replace a crummy Nady one that went bad. It has been excellent so far powering a pair of 15 inch mains and a pair of 12 inch monitors. There are alot of hookup options and plenty of power. I previously bought a Peavey IP3000 and it was a piece of junk. I returned it for the QSC and am really satisfied now. The QSC  GX5 is a good choice for a small to mid-sixe PA setup.

Great Amp!

Features:

Easy to use and nice x-over feature for an amp of this price from a very reputable mfg. Only wish x-over was adjustable.

Quality:

Made like other QSC products...reliable.

Overall:

For my small PA these are more than adequate. Runnig OAP tops with B&C loaded subs which are all 100db + in sensitivity. The amp never gets hot. I use the CX series in my large scale PA but the GX (although an entry level amp) is very nice. Sound is clean and clear and the GX 5 gets loud enough for most applications. I have 8 in my small system. Manual could be better for those who do not know how to use the basic features of an amp, but it really does not get easier than these basic amps. There are poor reviews from some once in a blue moon, but I believe these people do not have the tech skills to set gain structure at the mixer or amp. Use quality gear in the whole chain and NO ADAPTERS and you will not be disappointed.

Good amp but it's vent's fan is so noisy. It's manual should be better written in concise English. I don't know why  all electronic industry so cheap not to provided a DVD how to properly Installation.I am willing to pay a hidden charge or charges for it. I went to three or four techs for advise how to install all these amp, Mixer ,two passive speaker and pow er sub. All of them included SQC manufactory expert gave contrary accounts and none work. At the mixer I have to hooked up to the PHONE  in order to get the power sub to work but the sound came out extremely terrible no matter how you adjusted these 12 channels mixer.

Awesome amp...owned one for two years but another one to bridge...guess what??  These amps do not bridge you can set them for in individual output which builds you up to about 600w but NO BRIDGING.  It is a workhorse and if you get a little over zealous with the power it shuts down and saves your system...running PVDJ S5's, Kustom, Gemni, and EV Speaker systems with this unit and solo and keeps on tickin!!  Musicians Friend provided great support via the technical support to help me with my bridging problem.
