line 6 pre-amp/power amp question

[Jay_SDS]

i have a pod pro line 6 pre-amp that i am running through A 150 WATT power amp. currently i have the output of the pod pro all the way the way up ( maxed out ). i control the overall volume from the power amp. on our last 2 shows i have had to have my rig a little louder than normal and the power amp started clipping and would cut out for about 15 seconds through out the first few songs until i had to turn back down. ( to where it was really hard to hear myself and made the signal to the board weaker through the mic )
my question is .... should i have the power amp volume all the way up and control the volume from the output knob on my line 6 pre-amp & would that eliminate the clipping problem?

let me know what your input is on this

thanks
Jay

if you need alot of volume, then yes, I would turn the Poweramp's volume to between 3/4 and full and then start using your preamp's volume. that way, you dont have any Preamp clipping happening.


hope that helps!

actually its the power amp thats clipping and cutting out, the pre-amp is fine

Yes, but the hot signal from the preamp could be causing the Poweramp to clip and overload, causing the dropouts.

if you need max volume, dime the poweramp and bring the preamp out up until the levels are right.

If the problem still persists, have the poweramp looked at by a qualified tech.

You really need to make sure that the output of the preamp isn't overloading the input of the power amp. Is the maximum output of the preamp more than -4dBu? If so, you cannot go into a line input of a power amp, and you will need to lower the output of your preamp a bit. (I usually run my preamp's output at about 75% of max) Another thing to try is bridging your power amp into mono. This will give you a lot more volume, control, and headroom!
