How do I bridge my QSC GX 3 amp to run one speaker cabinet?

MAckie 1604 VLZ Pro Mixer, running QSC 1850 with jbl's from main outs. I would like to hook up powered subwoofers. What is the correct pathway? kenshireman@msn.com


The best way is to use a two-way crossover between the mixer and the amplifiers. In your case, the low output from teh crossover would go to the powered subs, the highs to the QSC. Use the crossover adjustment to set the frequency crossover point to get the sound quality you require.

My QSC GX3 has a red light that turned on (on the front panel). The channel is not working. Is this a fuse or something else?


You should check the speaker set, maybe it's short circuit.
Try remove the speaker set from the unit, than switch on the amplifier again, if the red light still on, surely the final drive is damages( Transistors or IC's).
Replace it with new ones.
