If you play loud enough to light up the protection yellow light on a Nashville or Vegas:
Should you turn down the channel volume knob?
Turn up the channel volume knob?
Max the main volume knob?
Change out the value in the protection circuit?
Get an amp with more headroom?

Break the little light.
Seriously.
They're nice compressors, at least on the Nashville.
Get two of them. It'll come on half as much.

#3-Max the sensitivity/master volume control.
The sensitivity control determines how much signal is fed to the input of the internal power amplifier.
or;
#5-use more than one amplifier.
or;
mic your amplifier and feed it through the main system, then feed it back through the monitors.
By the way, I do not recommend that you defeat the DDT circuit as this will increase the chances of speaker failure if the amp is being played at maximum volumes.

Back when I played clubs I always ran my sensitivity maxed out.They tell me I played really loud.I never remember seeing the yellow light on any of my Peaveys.But maybe the lights just didn't work on mine.
If you place your amp in a chair behind you and you have the lights going you'll know it the next day.I always placed mine just to the left of me and aimed it towards the guitar players head.  |

The largest sine waves that clip any amp are the bass frequencies. When you need to get the sound off the stage and have headroom, turn the bass down and increase the mids. If you need more bass, then bi-amp the preamp and use a larger power amp for the low frequencies and a cabinet that is efficient in that range. If I recall the old Session 500 had a varibale crossover and biamp outputs. That way you could use the internal amp for the higher frequencies and an alternate setup for the lower frequencies.
An intersting thing about audio is that the highs ride on the bass frequencies. When a clipped signal is feed to a standard PA cab with a passive crossover, the horns are the first to blow! The large sine wave clips the highs first. That is why an active crossover (before the power amp) rids a system of this problem. In a bi-amped system you will find the power amps for the highs are much smaller in power than the ones required for lows.[This message was edited by Ken Fox on 12 October 2004 at 08:38 AM.] |

You especially have to watch out for "clipping" and overloading when using a powered volume pedal, since some of them can throw more input voltage into an amp than the amp's designed for.
(I'm surprised Mike didn't mention this.) |

Donny I also use an effects proccessor that has some preamp potential. I am running it into and out of the effects send of the 400. I assume this has a bearing on the situation stated above.
I might try turning down the Hilton and turning up the amp. Thoughts?
