Andy Boy Posted November 16, 2004 Share Posted November 16, 2004 I've recently come to own an ampeg SVT IV pro and HLF cabinet. The cab is rated at 4 Ohms with Program Handling:1000 Watts and RMS Handling:500 Watts The head is rated at RMS Power Output (4 Ohms): 490x2/1200 (mono-bridged @ 4 Ohms). My question is "is it safe to run the head mono-bridged into the HLF", One music store told me yes, and other told said that it wasn't a good idea.

getz out Posted November 16, 2004 Share Posted November 16, 2004 Yes. That's the short answer. There's a much longer answer. - I have pumped 2,100 watts into a cabinet that handles 350-watt RMS. - I have powered a 300-watt RMS cabinet with only 200 watts. If you know what you're doing, either scenario is fine. If you don't, you should learn about gain-stages and amplification. Have you asked Ampeg what they think? Ask the music-store folks "why?" Asking questions is usually the answer (just like you did here). PS - search. Link to comment Share on other sites More sharing options...
BenLoy Posted November 16, 2004 Share Posted November 16, 2004 The music store employee who told you it "wasn't such a good idea" either has no true knowledge of gain structure or was afraid that you'd blow up your amp and then angrily come back and blame him for it. I believe it's always a good idea to play with more power than your cabinet is rated for. You get more headroom (ample reserve power) and lessen the chances of hurting your speakers, but only if you exercise restraint with that volume control. That means don't just turn the darn thing all the way up and then act surprised when you blow your speakers. Start with your master volume all the way down, and your EQ set flat. Turn up gradually with the band playing until you can hear yourself. If you're still having a hard time hearing what note your playing, try gradually boosting the low mids around 150Hz. Hope this helps. Link to comment Share on other sites More sharing options...
g. Posted November 16, 2004 Share Posted November 16, 2004 150 HZ is still widely considered as being in the bass frequencies. Maybe after a few more people start playing basses with low F# strings, that will change ; } . Link to comment Share on other sites More sharing options...
Andy Boy Posted November 16, 2004 Author Share Posted November 16, 2004 Thanks for the information, i've always been confused about matching heads to cabs. Getz76 can you tell me any good resources where i can learn about gain-stages and amplification? Link to comment Share on other sites More sharing options...
getz out Posted November 16, 2004 Share Posted November 16, 2004 A-Boy, THIS THREAD discusses some general misconceptions and misinformation that is passed around. THIS THREAD discusses how to EQ and "EARTHSHAKING LOWS." THIS THREAD has some info as well. Also, check out websites like QSC Audio and Eminence Speakers, as they tend to have a lot of good information. Link to comment Share on other sites More sharing options...
