Question about JVC TH-M505 System

Open Question

Whenever a loud sound is played the sound turns off, I can listen to it at a very low volume like around 20 with no problems, but as soon as I turn it up the sound clicks off. It sounds like a relay in the subwofer unit but am not sure if thats exactly the problem. The fan is not working so i opened it up but the way its acting i'm not even sure if thats the problem. The dvd plays fine and all speakers work, I'm thinking it is an overheating issue, I adjusted all levels of sound to its lowest setting but it still clicks off.

Sounds like your original and this sub have bad amps. The amp for the sub is not the same as the amp for the other speakers. The old unit has a dead amp and this new one is on the way out. (Pulling too much current on high bass)

SOURCE: Loses sound during loud moment in movie or if sound is above 30.

I want to say I used to have this same problem. Make sure you have the right speakers wired to the corresponding wiring places on the back of the sub-wolfer. If I remember correctly I had the front and rear speakers wired into the incorrect place. It would then get to a loud point in the movie and then just cut off as a safety to not blow up the speakers (I guess). May also want to try turning down the volume and replay that point in the movie until you find the sweet spot volume level if it can't be fixed.

Hi, You have to make sure you are using the "audio out" from the dvd/surround into the "audio in" on your TV also in some case TVs will need to change the "input" with your remote to see where you connected your dvd/sur also some TVs have a switch for "n" or "off" for internal speakers and also you could have that option in your audio menu on your TV, Hope it help, good luck.

You have a bad potentiometer which is a variable resistor. Might be the switch you are turning.

The sound output is very low even using earphones can the audio output be upgraded to give a normal listening level.

Probably not without using separate amplified speakers. Check the mixer levels are set correctly.

My amp turns on good but after a while of too much bass causes a ugly sound too loud what could it be? Can it be repaired?

If you have over driven the amp by playing it real loud with the bass control turned up, it is very possible that you have toasted the output stages of amp.
Every time you boost a tone control by 3 db you have doubled the output power at that frequency. So if you are "coasting" along at a nominal 75 watts, the moment you boost the bass by 3 db the amp has to put out 150 watts at that low frequency.. Go to +6db and now the poor amp has to kick out 300 watts! And so on.

Rule of thumb - you never use your tone controls at very loud levels. Tone controls are there to compensate for the poor frequency response of the human ear at low volume levels - the Fletcher Munsen effect. At low volumes our hearing with the lows and high frequencies so when you play something at low volume you boost up the bass and treble to compensate for poor hearing. At loud volumes our ears respond properly.

My crosley keepsake turntable has been having a lot of static and the sound is very low, I can only hear it if I turn the volume all the way up. I'm not sure if the needle is the problem or there is s

I would check the wires to the cartridge. It might that one or more is off or loose.
If you turn down the volume completely and listen with a record playing you should be able to hear (with your ear) the stylus in the grooves of the record playing the track. Pick a loud (rock) record for this. If it does that OK the stylus is good.

The music volume is low

Depends what you're listening to. If the sound can be turned up in other locations in your computer, then the encoding of whatever music that you're listening to may just be low. Turn up your volume from both your master volume on your computer, and from the application from which you're playing the music.

Bose 3.2.1 Volume is too low

ok on your receiver you have different settings this is not easiest to say and think and type at the same time so here goes

your reciever has different settings example sterio, mono expanded sound game sound etc.

i believe that if in wrong setting or the mpx is not on then you will get a low output of sound
also quite possible the songs were recorded at a lower output sound volume

i hope this made some sence

I have a philips tv 14inch model(14pt1353)

Hi there!
It may have something to do with your "PP" or Personal Preference setting. There is a sequence you have to follow. I think you have to press "Store", then "PP", then adjust Volume to required level, then press "PP" again and then store. Try playing around with this. Regards, JUS004
