A question For Mike Brown , Or any one out there that would know. How lower Voltage Will A DPC 750 or 1000 Power Amp run on without shutting down or damaging the Amps? And also a Nashville 400?

I would Appreciate Your help Thanks. J. T. Durham

It has been my experience that most well built amps will operate O.K. down to 90-92 volts. anything lower than that, it will start clipping,distortion,start squealing,and MAY or MAY not shut down.
As for doing any damage to it, I don't think so....... it just sounds like it.

(From a techie point of view)

Thanks Bill, For the Info, I was playing at a Park last year and my DPC 1000 kept shutting down, I thought it may be the voltage. So I’m Playing the same park this year I guess I will take a volt meter with me this time. I appreciate your help, Bill

If at all possible, try to make plans to have correct line voltage. But, to answer your question, and analog amp like the Nashville 400 is much more forgiving under low line voltage conditions. The 400 will work down to approximately 90 volts, depending on the total tolerences of the components in the power supply. If the tolerance of the regulators in the power supply exceed what they are designed to operate under, DC voltage into the speakers could result.

A digital amp such as the DPC will operate down to approximately 105 volts. When all LED's on the front panel of a DPC turns the color red, your in trouble as these amps are a bit more sensitive to line voltage fluctuation...............it's the "nature of the beast", so to speak.

I've used a Peavey Delta Blues amp in such a low voltage situation that when our drummers kick mallet hit, it sucked the power from my DB amp and the red pilot light dimmed! It was funny at the time, but now I always check to make sure that my employer(the person that pays our band)has at least 3 twenty amp breakers beforehand.

Hope that this helps.

I bought a used TrippLite voltage regulator from eBay for just such "occasions". At one club we play pretty regular, some nights things just don't sound right to either me or the guitar player. Since buying the regulator, we sound just as sucky every night.

Here's one similar to the one I bought:

Thanks Mike, For your help, I’ll just take my two Nashville’s when I go where we have to use long Extension Cords. I talk to you last year on the phone about this and you said the Nashville would work under lower voltage then the DPC amps but you didn’t say how much lower, No numbers. . I appreciate your help. Now I know what to watch for on both kind of amps. (Thanks)

J.T., Sorry I'm not that Jim Smith. I've never been to Illinois and I'm not that old!
