You might have a "dirty" volume control - with the power off, try twisting the volume control full to the left, full to the right, repeat several times - if this improves the situation then a quick shot of contact cleaner spray into the volume control might fix it for good.

This advice should work for potentiometer-type controls which consist of a metal wiper moving over an arc of carbon-coated material - dirt builds up under the wiper, preventing good contact.

Newer controls using an optical encoder will not be fixed by this method. If your amp volume normally adjusts in "steps" that you can hear, as opposed to continuously and smoothly as you rotate(d) the knob, then you have an encoder control.

Why could my volume knob be stuck on max volume and not adjusting?


There is probably grease or dirt on the contacts inside the unit. Here's a video that shows you how to fix it:

Mackie 450, signal light off, Sound only comes out when amp. turned up above 75%, when usually used at 40-50%. too loud at 75% and UP, does not Work at ALL below 75%. only 2 years old, with 25 uses... i...


Doesn't sound like a fuse. They don't fix themselves when you reach 75%.

Try shaking the volume knob while in the 30-50% range and/or try (with the power off) rotating the volume knob numerous times from 0% to 100%. If when you plug it back in it responds ANY differently, you might have a bad volume potentiometer. If when you shake the knob you hear static or intermittent sound, you have a bad volume pot.

The only other thing I can think of is that the wiper of the volume pot is not in contact with the windings inside the pot until you reach the 75% mark. When the volume comes on at 75%, does it start off kind of "static" then come in loud and clear? Also try this.... adjust the volume pot to 74% (or when the sound just begins to come on). At this point shake the knob. If you hear static, replace the volume pot.

Unplugging it when still on shouldn't cause any damage... in fact it probably hasn't considering it works at 75% plus.

I just bought a Coby home theater system 5.1 surround sound dvd/cd/ player model#765. I've got it all hooked up but I have one problem, when I want to listen to my tv stations through the home theater...


Hi - Your Home Theater System and your TV should have separate volume controls. You should be able to control each individually. Start by checking the volume level on your TV with your HTS shut-off. Turn the volume on your TV all the way down to 0.

Next, turn your HTS on and check the volume level there. Is it still loud? If so, try turning the volume down on your HTS. That should do the trick. If its not loud then you know you can control the volume on either the HTS or the TV. If this answer does not help, then please write us back with a little more detail. Thanks.

After a long effort searching on Google, I found a solution. There is a Late night setting on the remote that limits the loud sounds scenes so it is not much loader than the dialog. Works great, I can't believe I never notice the button before.

Loud distortion on Front Channels


Well, the nice thing about the newer amps is that the actual amp circuitry is all contained in a module and you don't have to do much troubleshooting. Just replace the module for that pair of channels. Bad news of course is the modules can be pricey. Should say right on it the part number, order it from mcminone.com or whoever, solder it in, use new conductive grease (many times I think these modules fail because the grease gets old, the module overheats and toasts) and you should be fixya'd

HAVE TO UP VOLUME ON DENON 2106 TO HEAR ALL AUDIO IN NIGHT MODE


There should be a volume adjust on the center channel. This is done by the remote exclusively. You may also wish to compress the sound using the dynamic range compression button or so labeled.
