www.prometheus-design.com Posted April 12, 2002 Share Posted April 12, 2002 Has anyone experienced any probs running the PLX series below 4ohms in bridgedmono? QSC doesn't suggest it, but I think they are just covering their butts incase someone burns one up. Here is what the site said. Any Thoughts? PD :rolleyes: -----qscweb---- Can I drive a 2 ohm load with my QSC amplifier in bridge-mode? The minimum rated impedance for an amplifier in bridge-mono is 8 ohms. A 4 ohm load is possible as this represents a 2 ohm per channel equivalent. Two ohm load precautions still apply, as it would with any amplifier, so supplemental cooling may be found necessary. It will also be important to watch for any impedance transients that arise from the speakers in use. Four ohm bridge-mono loading is the absolute minimum across the entire audio range (20Hz - 20kHz.)

Anoplura Posted April 12, 2002 Share Posted April 12, 2002 I hope you own a fire extinguisher. ;) If you need more power, add another amp. You'll cook the output transistors trying to run your amp at 2 Ohms. Link to comment Share on other sites More sharing options...
www.prometheus-design.com Posted April 12, 2002 Author Share Posted April 12, 2002 2.66 ohms is about what an amp reaches at peak performance sometimes on a 4ohm load. Why can't it handle it more of the time? I run a Crown CE2000 on bridge mono 2.66ohms for our subs and have never had a problem. Whats the catch?

www.prometheus-design.com Posted April 15, 2002 Author Share Posted April 15, 2002 The PLX series has temp control as well as auto shutoff in the event they were overloaded. Will it really endanger the amp to try it and see what happens? PD :rolleyes: Link to comment Share on other sites More sharing options...
