Wrap a wire around the outside Metal of your rca jack in back of your radio and ground the other end of that wire to the back of your radio and the noise goes away

Scrathy rec audio


older batteries or not fully charged batteries can cause distorted RX. if your batteries are more than 2 yrs old they should be replaced. also dirt or moisture in the radio speaker, or trying to talk beyond their Range can also cause distorted RX. you use most of your power when you transmit.

Marshall MB4410, with low volume gives no real volume,


Guitar amps have preamp sections (think unpowered audio mixer) and power amp sections (Crown rack-mount amp). An excellent way to isolate audio problems if amp is still producing audio is to check the preamp out (line out). Preamp output distorted = preamp failure. Connect MP3 player to "Power Amp In"...sound distorted = power amp failure. In your case the latter is the case as your "line out" is clean. Also test each speaker for clear sound as speaker cone damage from being overpowered is fairly common. At 300w. I'll assume the failure was not from cranking the volume to loud but a shorted speaker or speaker wiring could zap the power amp in an instant.

Speaker produces noice/static/buzzing sound when it is off


That means that if too much power is going to the speaker or extraneous signals are being picked up by the wiring, it can come through the speakers as static. Stopping static requires finding and eliminating that extra electricity from transmitting through your speakers.
If you're still hearing distortion, turn down the volume on your amplifier until the distortion goes away. If the volume is too low to be easily heard, the problem may be that your amplifier produces too much power for your speakers to handle or that your amp and speakers have different impedance ratings.

I get no sound at all when I plug in to the input and its not my lead or guitar, how can I fix the amp?


This is probably not a DIY repair. You best take it to a repair shop. Likely the power amp has failed or other common problems are broken connectors/jacks, broken volume pots, and finally circuit board cracks.

I thought there was a problem with the speakers or receiver, but after turning off the speakers and listening to the sound from the needle, it appears that the distortion is coming from the turntable. The...


The "needle", now called a "stylus", doesn't produce anything on its own. At the worst, the tip will shear off and it will slide across and damage the vinyl. So probably your "cartridge" is defective. Now, most low rumbling distortion would come from your turntables motor or platter bearings. Also if you unplugged the Phono leads from the preamp ports in the back of your amp and the noise goes away then you have learned that the amplifier is not producing the effect. Does this help?

Amp went into protect, but front speakers sound distorted too


If the amp still goes into protect mode, the easiest thing to do is disconnect the RCA cables from the amp and see if still goes into protect mode (after turning off/on). If it does, the issue lies in the amp or the wiring to/from the amp (most likely case). Check to make sure no speaker wires came loose and touched +12V or ground (car body). From the sound of it, my guess is something internal to the amp died and will need repair.
