Hi guys, I am very much an amateur but will be setting up the audio for a talk at a community center on Wednesday. I am finding that one of the speakers isn't receiving the audio so well, to the point that the sound can only be faintly heard. I don't know what is causing this. The speakers are JBL G2/230. They both have a small red light labelled "mic" on the back. On one of them this lights up when plugged into the Soundcraft mixing desk, on the problem speaker it doesn't.
Anyway, I have tried plugging the mics into the desk via a shorter XLR to TRS cable into the "line" input. I also tried a very long XLR to XLR cable which I guess is at least 8 metres long. I'm not sure if this would reduce the signal from the mic or if the TRS to line cable is better?? The result is very similar regardless of the cable or which mic is used - It is still a fairly weak sound through one of the speakers. The strange thing is when an ipod or other music source is plugged into the mixing desk into the "2-track" inserts the speakers both work fine.
So my question is if I have a problem with one speaker what is the best way to deal with it at the desk? Would raising the input channel fader to a high level for the mic and keeping the master faders on the low side be the best way to avoid feedback and hissing sounds or would it be the other way round?? Also, would lowering the gain to the lowest possible level make a difference?
I have limited experience working with mixing desks so am panicking a little bit. I have made sure the settings on the back of the speakers are the same but can't think what else to try.
