Opinion on new QSC amps?
« on: November 13, 2006, 03:33:15 pm »

Im currently running 10 qsc pl236 amps.  I like them very much.  I am building another rig and Im wondering what people think of the new plx3602.  Specifically Im wonering if people who own both have a preference.

As far as i've heard is that internally they are pretty much identical to the 3402 (the older version). This is from a rep at QSC Directly. The Pl236 has a data port and some other fancy gizmos but input and output stuff is pretty much the same.

Hope this helps

Caveat:  I am a QSC dealer.

I've used/listened to the PL2, PLX, and PLX2 lines extensively.

One consideration when comparing them is to compare similar topologies -- some models are class AB, most are class H; there are subtle differences in sound which do not indicate a difference between lines.

That said, my impression is that the PL2 line is somewhat more neutral and somewhat tighter sounding.  They give the impression of having less bottom, when in fact the "less" is less overhang.  The PL2 line is very revealing of source and speaker problems.  The PLX and PLX2 lines, on the other hand, could be said to be "musical" -- or veiled -- depending on the spin you want to hear/use/sell.  These differences are not large -- when we compared them we did it in a reasonable acoustic environment with studio monitors and measured identical amplifier outputs.  

If you are going to overdrive the amps (below 2 ohms or well into clipping, etc.) the PL2 will be slightly more robust/recover from overload slightly more cleanly.  All of them will actually drive 2 ohm loads with full power test signals long enough to measure the output, unlike some other highly regarded amplifers.  

At their price point, the PLX/PLX2 are hard to beat for sound/power/features/reliability.  At their price point, the PL2 have a fair amount of competition.

As an aside, if your needs fit the product, the original PL series (what remains of it) are seriously good as well -- but they are deeper, taller, heavier, and can have significantly more power....

Aside from the configuration switches, the high-pass filter, signal level display, and the DataPort-related circuitry, the audio and power supply circuitry of the PLX 3602 is nearly identical to the PL 236.

The pl236 is loaded with a bunch of great features. The pl 06 series is bang-for-your-buck power.

Both of those amps generate a bit of heat Smile - but good solid amps!

All my QSC stuff has been great.  I have 4 3402's from very early in there product life and they have been solid for years.  I suspect these will give you a long life.

I have used QSC amps for many years recently retiring an old USA-850, 10 years old. I have used and heard both of the amps you mention and own a few of the PLX series amps as well. Other than some additional management features there seems to be very little difference. I have never had a QSC amp fail and would expect the same from any QSC amp regardless of series.
