question for QSC users

A bit of fan noise is a small price to pay for the benefits the fan provides. Remember that heat is the natural enemy of all things electronic, especially amps. Amps with active cooling blow up a lot less often and last heaps longer than those without.

You shouldn't have a problem with the fan noise at gigs. The dull roar of crowd chat will usually be much louder than even the noisiest fans. You may have a problem in the recording studio but there isn't a a fan out there that is quiet enough for the studio. The way around this is to put the amp in a seperate room to the cab. You'll need long speaker cables for this though.

 

I was not aware that this happens

 

It's not an issue if you're in a large place w/ people in there. I played an outdoor show w/ mine. Someone asked me about how bad the fan noise was on it before playing. We were standing 3 feet away. I told him to put his hand in front of it so he could feel that the fan was on, and he couldn't hear it.

Complaining about fan noise is really nitpicky folks. You know it's gotta have one, but yet it bugs you. Do you all have some kinda OCD?

 

I just had a thought. Some amps have a variable fan speed so you can turn it down if it's blowing too hard. I'm not sure about QSC but it can't hurt to check.

 

I have the 3002 & 2402....and fan noise is not a issue at all.....great amps!!

 

I don't notice a noise per se, but rather a drone from the fan on my PLX3002. I have a PLX 1602 and it sounds the same way. I don't find it annoying. If you want fan noise, you should try my QSC model 1700 amp!!

 

I don't find that fan noise, in my PLX's any louder than what is in my EBS Fafner or my WT-800. But the PLX doesn't seem to vary the fan speed as much as the the one in the Eden stuff.

That PLX is a wonderful amp. I'm very happy with mine.

 

PLX2402 here.
Great Amp
No fan noise issue. I can hear it but it doesn't squeel. Sounds like a defective fan. It happens.
My fan keeps me cooler when I sit in front of it practicing.

It does run harder and possibly louder when I bridge. I'm still going back and fourth with bridging though. For the most part I don't with 2402's extra power.

 

I have a 1602 and the fan on mine is drowned out by the guitar players single coil hum amd the keyboard players vintage tube buzz. The fan on mine isn't any louder than any other fan cooled amp I've heard.

 

Fan noise: small price to pay for 3000 watts in a 25 pound package!!!!!!

Stewart have some fanless high powered amps (not 3K watts, though).

(I've got an Alembic F1X + PLX 3002 also)

 

Petebass: the fan speed in the PLX amp varies with the heat sink temperature; if the heat sink is hotter, the fan will move more air than when it's cooler.

thetaxmiser: Well, it's a subjective thing, but I use my PLX 1602 every week in church and no one's ever complained about the fan noise.

FWIW, the RMX amps have noticeably noisier fans, but no one's ever mentioned them being objectionable ... only the PLX!

 

Just dumping a rock on top of a mountain that already exists in this thread - I was surprised by the PLX's fan noise, too, when I first hooked it up. In relation to my Carvins, it is loud.

BUT - when it's time to go to work, it doesn't matter one bit............unless you place a mic by the fan!

 

I have a PLX1602. The fan on mine is barely audible in a quiet room 10 ft away, no whine at all. Maybe you need to have your amp checked.

 

I'd hate to work in marketing.

 

I have a PLX1202 and on the gig I don't notice the fan noise at all. In the studio it is distracting. I think that when you play it in a live situation you won't notice any noise.
