The PLX3602 power amplifier is an excellent choice for users who need to drive up to four loudspeakers from each amplifier channel (2-ohm loading), or when extremely high power bridged mono operation is required. Features built-in subwoofer processing, filter switches, and front panel indications of bridged mono status.

The PLX3602 power amp has a solid, cast-aluminum front panel that adds professional style to any rack while also acting as an integral I-beam, rigidly tying the chassis together for years of on-the-road reliability.

Additional mechanical touches such as the side stiffening rails, rear rack ears and cable tie anchor points attest to QSC's years of experience and attention to detail. QSC has even designed the integrated front handles so the amplifier slides into a rack without scraping your fingers on the rack sides.

PowerLight Technology
PowerLight switchmode technology replaces a large, heavy AC transformer (typically 20 lbs.) with a highly efficient and lighter-weight active design. Conventional AC transformers provide 100 or 120 energy pulses per second; the PowerLight supply delivers 190,000 to 230,000 pulses per second. More pulses make it easier to provide on-demand power for the amplifier's output section. The power supply doesn't sag so bass notes stay full and powerful while the high end remains crisp and clean.

Audio Quality
PLX2 audio power circuitry achieves performance normally associated with studio reference amplifiers. In order to reduce crossover distortion, precision bias tracking makes minute adjustments as amplifier temperature changes. The benefit is cleaner high-frequency and more consistent sound no matter how hard the amplifier is driven.


  • Stereo: 1800W/ch @ 2 ohms, 1250W/ch @ 4 ohms, 775W/ch @ 8 ohms

Crisp, Clean, Power & Light Weight! :o

By Lil D*J*

from Lodi, CA

Comments about QSC PLX3602 Professional Power Amplifier:

This amp hasn't failed me plus it's really light weight! When you working with live sound you need a great amp that won't fail you during a concert. Also one that can deliver crisp, clean and powerful sound and POWER. QSC has always made great amps, but this is the best series yet because these amps weigh less than 15 pounds!!!! At first I didn't belive it but when I went with my friend to buy new amps he bought one from this series....... when I held it in my hands I was shocked, because I thought I was going to break my back! I'm telling you people this amp is worth it.

When you want headroom...

By Sound Logic Productions

from Milford, CT

Comments about QSC PLX3602 Professional Power Amplifier:

You can't go wrong with the PLX3602. The power that this thing pumps out of such a light 21 pound package is just amazing. Sound quality is absolutely great. With the built-in crossover and clip limiting on top of power to spare and 2-Ohm capability, it's very easy to push subs and mains off one amp when you're trying to maintain a mobile rig. It stays cool, and has yet to cause me *any* grief. And it can power just about any pair of cabinets you can throw at it without breaking a sweat. The thump from my Yamaha SW118V subwoofers's is just amazing on this amp. Of course, with the legendary QSC quality, the 3-year warranty will most likely not be needed.

Best amp on the market


from north of baltimore md

Comments about QSC PLX3602 Professional Power Amplifier:

this amp is the best, bar none. it will run any speaker setup you can throw at it. its light, clean sound, and very little hum. i use this for my harbinger dual 15 inch mains, and a rmx2450 to run two yamaha club v series 18's. ill be switching to a plx series for the subs as soon as i can afford to, as the light weight in my rig is what im after. the fans are really efficient, did a fourth of july party for 10 HOURS and it was outdoors for my family. 90 degrees, 70% humidity and the fan didnt even go to full speed. got to love it. qsc OWNS all others.

Professionalism is an understatement!

By gguillo

from Little Rock, AR

Comments about QSC PLX3602 Professional Power Amplifier:

These amps have got some serious power! They run super quiet and super clean. We have two of these that are used to run (2) JBL MRX 528s @ 3600 watts @ 4 ohms bridged. They lows are crystal clear and very punchy! The damping factor is >500 which is perfect for subs. There is not much to this amp at all but raw power. Very simple to set up and easy to use. I recommend this amp to anyone wanting to power high-end subs such as JBL MRX 528s, JBL SRX 728s, Cerwin Vegas, or Turbosound. I know that these particular names can handle the power. If you are using these to run mains, be sure to check your power rating and handling first.
