I just hooked up a new system with the MONSTER ELEGANZA speakers and the Monster MPA 5150 AMP. After only a couple of days I noticed bad static coming from the Left Main speakers. After switching connections to narrow down the source, I find that any speaker plugged into the left output has static. Is this a sign of a failing left channel amp already?
Might be a failing semiconductor component (usually an old transistor) in the amplifier's front end. This caused by the oxidation through the component legs or pin. I usually touch and move each transistor's body to exaggerate the noise. You can research also what kind of noise is it producing- intermittent, static, etc.
hope this helps..

It would not be recommended, as the intent of the amplifier is to drive 5 individual speakers in a home theater setup. Bridging channels on the amp could cause damage and would definitely void your warranty. I would recommend simply not using two of the channels if you are looking to drive 3 speakers instead of 5.
Do you mean HDMI from Monster, if you do ensure that the cable is connected securely to the correct port. HDMI cables rely on both the devices for sending and receiving. Nothing will happen until both devices send the opposite signal. Hope it works for you!
You should contact the seller and get them to sought this problem out by supplying you with a new one or getting your money back. If you can't sought it contact Monster.
I have the same problem only its the left front speaker. I took my mp 5150 amp to a professional and he told me the problem is a modulator or the MU-1 part. This is a special part on the board that is designed by Monster and no one will have in stock. Each amplifier in this unit has its own MU-1. I am currently waiting further information.
This could be a semiconductor overheating, so when it's left running it acts up. But when cool it plays again. Could be in the power or something that effects all channels. You might be able to find it with Servisol Freezer spray. Wait for the suspect part to heat/act up, then spray it. It should burst into life, when you do so. To be certain apply a soldering iron to it (metal piece). This will cause it to act up quicker, then spray again, to confirm.
Not to discount what your tech has already said, there are a few things that can cause hum. Just want to get info direct from you regarding this problem. Then, I can attempt to point you in the right direction if you can provide me with answers of a few questions
is the hum still there when you disconnect the inputs
does the hum increase in vol when you turn up the preamp
does the amp run hotter than normal
is the problem on both channels
did any event or contributing factor induce the hum or did it just start out of the blue
do you have any warranty on the amp
If you could answer these questions for me, then I will convey what I think to you. Cheers
As It was mentioned on the premium post, if after removing the fuse(s) from it, the amp powers up and stays ON; the failure is on the transistors or mosfets and they will need to be replace to get the amp working again on channel 4.
I would suggest to contact the manufacturers to get an authorized repair center to fix it under warranty if your amp is less then a year old.
Good Luck.
Nice amps. There is really only one check you can do without getting into the internals of the amp to help you resolve the issue. Disconnect the input and speakers from that channel,and see if it is able to turn on. If are up to it, checking over the poweramp board for that channel for
dry or cracked solder joints, and in turn resoldering any you find may
fix the problem. If not, the amp will have a problem on that channel and will need a tech to look at it. If it is under warranty still, Monster are pretty good for service I have heard, and they would be your first port of call. Other than that, Call you local HiFi specialist store and see if they can recommend a good audio tech in your area.
