Extension cord for my Crown XLS 2502 amp.

Thanks TLS Guy! I will go with a 10ga. What does SJTW mean?

Search and ye shall find.

If you're trying to learn more about the SJTW cable, you might find it fascinating that the cable has a number of different applications.

I found that too but it's not for the XLS2502. Perhaps an indicator but not real data for this machine.

The amp part of the 2500 and 2502 are the same.

I had a similar situation with my Crown XLS 2002 amp when I needed a 25ft cord for a gig. I was worried about power drop too, but getting a high-quality extension cord transparent made all the difference. It’s cool because you can actually see the internal wiring, which gave me peace of mind about the build quality.
I found mine after looking into options on a site like Global Sources, and it handled everything perfectly—no overheating or power issues, even when the amp was cranking. Just make sure to go for at least a 14-gauge wire, or even 12-gauge if you’re pushing the amp hard.

I'm pretty sure that the Crown has a Switch Mode Power Supply. So it doesn't care about AC line cord voltage drop.
It can output full power with a wide range of AC line voltage.

All of my recent crown amps from the xls series do with the voltage range and at what HZ clearly listed on the unit.

Remember that cords and breakers are rated for 3 hours of continuous (rated) current.
So unless it's playing full volume test tones the cords and breakers are just loafing along.

But the level of music isn't consistent, so that really doesn't apply. Good to be safe, but there's plenty of margin with a 10ga or 12ga cord.

EVERYTHING cares about voltage drop- it's just a matter of how tolerant the design is.

Crown tech support said the current draw is 7A with 2 Ohm load, 1/8 power nominal output. The equipment (these models) sold in the US are made for 120VAC line voltage, this will not be happy with excessively high or low voltage. Their amplifier sales are region-specific WRT line voltage- they're available for 100VAC, 120VAC (US), 240VAC and the 120V version will not be happy with 100VAC or power systems providing voltage higher than 120VAC.

Perhaps they should switch to a non-regional power supply?
