He gave me different info about running amps at full attenuation tho.. http://forum.qscservice.com/viewtopic.p ... e30#p21133

Yea I have the multimeter hooked up to the output, black to black red to red. Over at the QSC forums they told me 80v is a reasonable clip point for that amp running a sine wave.

Im getting 80v at clip point...

Plugged into the wall of my house is reading 120...

Im unsure about Ohms. How do I know Im measuring 4Ohms as opposed to 8?

Yes the clip lights are coming on the amp forsure. Just tried multiple channels and multiple cords nothing seems to give me a reading other than 90v

It doesnt seem right everyone else is stating max volts from a gx5 at 60-65 volts w a 1.2v input sensitivity. How do I know that my mixer is putting out the 1.2v? is that standard?

Yes Bruce I checked both channels and they were roughly the same. How do I know if I'm checking a 4ohm or 8ohm load? Also is this amp just too powerful for my setup?

I have 2 GX5's
powering two t39's 3012lf
and two peavey tops

Hey so Im still stumped... I bypassed the PA+ and hooked my board straight up to the GX5 and was getting 100+ volts at clipping on the board. Is this abnormal? should I be checking another multimeter?

edit:

The main output trim knob actually goes from -40 to 0 dB while the Mono output trim knob does -80 up to +6 dB just to clarify I’m using the mono output..

Ok, so I originally set the input gain on channel 15/16 to just below clipping. Then when I got such high voltage I decided to leave it at about 2/3 of the way up, which I thought was 0. Not sure if it is because I’m still learning to read the metering on the SL16.0.2 and its a bit crammed due to th...

Ok. So Im using a 60hz test tone coming off Youtube through my phone into RCA inputs on channel 15/16 on my Studiolive 16.0.2. From there it is going out the mono output at max using XLR into the driverack PA+. Then from the low output on the PA+ into a channel on the GX5. GX5 is cranked and i got t...

Could it be im not using a TrueRMS meter? The one im using is a a digital one you can get from the hardware store set on ACV 200

HAHAHAH you guys are too much! Tho the banter is entertaining, I am still having trouble getting my limiters to engage when my mixer is at unity. They want to come on way too early still. My multimeter is still pumping out 85-90 volts when everything is wide open, using the mono out changed nothing....

Thanks Grant. I will try the mono output and see if I can get my voltage limiting set up right.

I have the PA+ actually. I saw the mono output, but thought it might be nice to do some panning and fx sweeps? Is that really necessary for live sound? Im not sure. I will search around for the gain structure threads. Any more info will be helpful, especially the stuff on using the multimeter correc...
