Alesis M1 Active Mk2 Speaker won't Power Up

I have a set of studio monitors. One of the monitors will not turn on. The LED doesn't come on and no sound emits from the speakers. Blown fuse or bad power supply?

    Same problem. No power at all. Fuse seems to be okay.

Hi, This is usually the Capacitor C8 on the powerboard it usually bulges and pops, its becuase its right next to a resistor which gets very hot and sometimes puts the capacitor into meltdown, yours might have gone past that stage but this is worth a look; http://www.neufeld.newton.ks.us/electronics/?p=232

Hope this helps

Cheers

Steve

    I found C8 and moved the resistor away some and wiggled the C8 capacitor and it works now. Thanks Steve

Alesis M1 Active 620 studio monitor cutting out


I see from the manual there are several controls on the speaker that could affect the sound in the way you describe (gain, hi- and mid-boost, acoustic space). Why don't you compare the actions of each control with the working speaker as the standard and a test tone or FM noise as the source? It might help you to identify a specific internal function that has changed. After that, someone's going to have to crack it open and do surgery.

You might also try using the opposite input (TRS vs XLR) than the one you're using. It might reveal something.

Alesis 620 m1 active studio monitors sound cutting out


It could be a power problem, unless you have blown the driver ?, carefully pull out the power supply board, and look to see if anything looks melted, burned, or capacitors popped etc. Be carefull though as I do not want to be responsible if you get an electric shock, etc. preferably look and dont touch, just use common sense ;)

ALESIS M1 ACTIVE MK2 CONE VIBRATION!


Hello!
my speaker Alessis M1 Active 620, with a roar is very strong in the speaker, the potentiometer does not attenuate, change the volume. Ja switched capacitor C8, based on my research of other users, but got no result. When you press the power button, the LED lights in blue, and even change the color to red, producing a noise (snoring) very strong.
help!
Please help me!
