The BX250 and many other amplifiers use the same solid red light to indicate both that the signal is muted and that the amp is in protection mode. After ten seconds of being powered off, the amp is reset, so turn it on and watch for the protection light again. Get your answers by asking now. I’ve had three Carvin heads that go directly into protect mode regardless of speaker load/cab used.

One of the most common causes is an impedance mismatch- that is, the BX250 is loaded below its minimum impedance rating (for more on this topic, check out this article). If the BX600 amp conks out, I’ll be replacing it with a Hartke amp again! It may seem that some don’t, because they consistently generate great work, but they’re human too. Odd. I currently have a 500-watt amp pushing 2 Lightning Audio 15"s An amplifier with a built-in protection circuit will have a protect light. It may or may not be the same color as the power light- there are many variations, so refer to your unit’s documentation if you are unsure where the protection light is or if there is a protection circuit. To cope with this I just have the boost set to an appropriate level to where I have enough bass to be happy without it causing the amp to shut off.

But if your goal is to really compel people, then you have to put on a show. Imagine if our amps could talk- there would be a lot less incidents of blown speakers and mismatched impedances! Not very confidence inspiring. Amps go into protect mode for many reasons. Could be the 8ga cable. Add the RCA cables first. Plus, it seems the amount of gear you need to put together a great record or an awesome show gets to be more and more every year. I set up for a nighttime gig about 3pm once and then left the venue to grab some grub before going on. I ve been performing live for some 40 yrs.

Comments will be approved before showing up. You’ll have to make the most of what you've got. Check to make sure that a speaker wire isn't being pinched somewhere between the amp and the speaker. My amp is at half gain and if I turn the amp setting on my deck down it wont shut off. The only problem I can think of is that I used 8 ga. wire for the power because that was all I could find at the time and I'm thinking of switching to 4 ga. Any suggestions on what the problem may be and how I could fix it? While troubleshooting an amplifier in protection mode, make sure that the mute switch is not turned on, as this will also cause the jewel light to remain a solid red. Did McCracken make that monolith in Utah? In instances like this, the protection circuit will kick in to protect the amplifier’s power supply. Immediately power off your amplifier and check the impedance rating of the cabinets you are using.
