Problems With Ampeg SVP 1500

[coreyleeitc]

Ok so I just bought this ampeg svp1500
I also have a sansamp RBI that I use.

I run into my tuner, out to my sansamp and into the svp power amp
I use 2 ampeg svt 4x10hlf's

I hooked it up today at practice and was jamming and all of a sudden i heard a volume decrease. Channel B had gone into protect mode but Channel A was still working and then after about a minute Channel A would kick off into protect as well.

I hope nothing is wrong but can someone throw me some hints?

Let's start with the cabinets. What impedance are they each? How are you connecting them?

That's an SS poweramp, probably made back around April 1997.

is the fan running? Does it speed up before the amp clicks off?

Are you running bridged or "stereo"?

What are you plugging into it, and where did you plug them in?

Surely sounds like overheating, possibly caused by a weak fan, or low speaker impedance, since you say you are not crowding the unit or obstructing airflow.

That particular SVP-1500 power amp is not the most heavy-duty. It is based on the Audio-Centron MP-1200, which was a budget-priced unit. It is a bit weak on cooling, but strong on protection, and wouldn't be my first choice for really beating on.

There is a similar unit, the SVP-1600, which is considerably heavier-duty.
