Is it me or are they nasty sounding adding a kind of 8 bit graininess. Used three 3602's to drive lo mid, hi mid, high on the r4's and it sounded pants. Has anyone else had a similar experience. ------------- DMZ. "The bass was intense. Girls were literally running up to stand next to the subs" |

Not me.
I have a 3002 driving low mid on Floodlights and it sounds fine.

Was looking at these as an option to power my tops? ------------- https://operationsoundsystemrecords.bandcamp.com/ https://www.facebook.com/OperationSoundSystem/ |

Shouldn't have an 8-bit anything, they have switchmode PSU but linear output stage ------------- Kevin North Staffordshire |

Always very happy with my PLX's. Sure it wasn't grainess elsewhere in the system? ------------- My laser stuff: http://www.facebook.com/SubsonicSystems" rel="nofollow - Frikkin Lasers |

| + 1 happy with plx, use them for tops. 1202 i think, qsc are always crystal clear, clean amps. |

PLX's work like wire with gain for me. They even clip very nicely. Tony |

| Another thumbs up for the PLX's, fantastic amps in my opinion. |

Hmm well seems that there might be a need to look elsewhere along the signal chain or indeed in the room itself. Some kind of upper low mid phase cancellation. Bringing the h mid and tweets up in the mix.. The search continues.. ------------- DMZ. "The bass was intense. Girls were literally running up to stand next to the subs" |

| I can confirm, I always found QSC amp a bit agressive... |

Unless it's defective, it wouldn't be adding anything. If the input signal is grainy, the output signal will be, too.

Hmmm shop bought cd Cdj1000 drawmer sp2120 sw9088iis 3 x plx3602 2 x qscex4000 2 x fk1 f218 2 x fk1 res4scp On paper it should be sweet. Single stacked the 218's subs with the r4s flown each side so as I mentioned possibly its a placement issue. Have yet to have time to get back to the venue for another play.. ------------- DMZ.

we use a 3402 on TMS5 mid/top and it is quite a good amp, but it's not the absolute best sounding amp out there. I've had early clip happen on it too but i think that may of been due to prolonged exposure to red light mixer action.
Never tried it at 2ohms a side, gets pretty hot at 4 a side but she just keeps on going...

Does your Soundweb have mic/line cards? BSS have confirmed to me that they have some noise issues. How about your cables? |

Not all 'bought' CD's have great quality these days in my opinion. Maybe just try one of your known well engineered discs also... |

+1 and it's quite the opposite ! the vast majority of the commercial stuff sounds bad with heavy compression and wrong tonal balance to meet the low quality standard of the "ipod / mp3 generation"

I have to say, I've driven our Res with our QSC PLX's a couple of times, and it's sounded fine.
Not AS clean, or as much headroom as what we normally use, but in no way harsh or grainy!
I happily use the PLX2's with all our Martin stuff, and can't see that ever changing!
I do prefer the older PLX's to the PLX2's though...

My 3 plx´s all sound very good indeed, never had a problem with distortion nor graininess even at clip. Altho i could swear that i detect a tad more thd on the plx2´s. Maybe im wrong, but thats my personal preference. |

Slightly OT but this track is on the 'Kenwood' Moved By Music hifi CD sampler that was used by dealers to demo their equipment when CD players first came out. It also has Average White Band (Pick up the Pieces) and Lonnie Liston Smith (Expansions) amongst others, all great recordings to test sound systems with! ------------- Kevin North Staffordshire |

Another generation's old classic. Gat Decor http://www.youtube.com/watch?v=6iDz648nzT8 - Passion http://www.youtube.com/watch?v=6iDz648nzT8 - : highly predictable lots of space to make hearing stuff going on in the room easy, pretty clean samples throbs along ------------- DMZ.

Hmm I was searching for this question as I heard Tony Andrews wouldnt recommend using QSC amps.. Unfortunately, used QSC´s are often the ones that are actually affordable. ... ------------- 1850 FRB C. (; |
