Sound quits on high volume - Computers & Internet

In-car entertainment systems, especially the types chosen for camper vans, etc., are often capable of quite high power outputs and usually need speakers capable of being driven at those high power outputs without damage.

The trouble is, such speakers usually don't sound so good at the very low volume settings needed for evening and late night use in a campsite environment to avoid annoyance to neighbours.

It is a big problem choosing speakers that sound good at low volume and yet can withstand the higher volume needed to overcome the wind and road noise of driving. There have been many technological advances in speaker design and a hi-fi specialist will undoubtedly be able to make suitable recommendations that are resistant to damp conditions, long-lasting and with cones free enough for good reproduction at ultra low volumes but robust enough to withstand high power outputs and such drive units are likely to be fairly expensive.

For myself I would choose to use a dual speaker system with a multi-speaker system comprising several low-powered speakers strategically placed for low volume use and a fairly standard high-powered system for normal use and a selector switch.

Are you using a box of some sort for signal with this set?

Check to see if the sound has not been set to mute and check the sound volume level.

I have a Korg C-15s and also experiencing loud crackling sounds when I turn it on. The problems seems to be either the sliding volume control or the amplifier itself. Honestly though, I believe the issue is the volume control. I opened my piano to get a closer look and attempted to clean the contacts on the volume. Unfortunately after cleaning the contacts, the crackling sounds became somewhat worse. After I turn the piano on, the volume control is generally rendered useless......volume set to low volume and the noise is quite loud and other times the volume control is set high and get very low volume crackling noise. No real consistency. The noise does diminish after a few minutes but so does the piano sounds to an inaudible level. There were a couple of instances where I turned it on and surprising enough, no no noise and perfect sound. For these reasons I believe the issue is within the volume control and not so much the amplifier. I have an electronics background and noticed that the volume control is very unique in design and is not something that can be substituted with another volume control from other sources.

My recommendation is to check the sound quality of the audio from the RCA L/R audio outs on rear of the piano by connecting to a stereo receiver. If it sounds fine you're in luck. If the crackling sound does not diminish after a few minutes like mine does, I would suggest disconnecting the internal speakers and using the audio out only. You can connect a pair of studio monitors or high quality computer speakers, preferably with a small subwoofer to deliver the full audio range and deeper tone of a real piano. I'm currently using a basic pair of Logitech computer speakers and is quite acceptable until I can afford a high quality set of monitors or relocate my piano closer to my high quality Yamaha receiver.

I hope this info helps a bit.

Best thing to do is to go to manufacturer website and download the latest audio drivers. Then make sure your sound settings are set to High as well the application you are using.
Some movies will be encoded with different audio codec which makes voice pretty quite.
Unfortenately some model laptops come with very weak speakers and you cannot get good volume out of them. If this is the case then your only option is external speakers.

Hope this helps.

Does it stop on both channels? It sounds to me like the safety circuit is activating. This usually happens when either the volume is too high, or the speaker load is too great (i.e. usually loads less than 4 ohms will do this) or, the amplifier has an internal short causing the amplifier's output stage to become un-balanced. Does the sound come out nice and clearly through both channels? How long does the receiver play before the sound stops? How loud are you playing the music when it stops like this? If the sound is reasonably clear through both channels at regular volume, then there is probably nothing at all wrong with the receiver's output circuits. If the amplifier is being played at regular volume or even lower volume for quite a while and then quits, perhaps the receiver is getting too hot and it's thermal sensors are activating the protection circuit. Make sure that when you operate the receiver, that there aren't things laying on top of it blocking the unit from venting and cooling properly. Make sure it has plenty of breathing room - amplifiers (most of them anyway) are inherently subject to producing heat. If the amplifier only quits when played at high volume, well then that's probably the problem - it's probably not meant to deliver such power that you're asking it to - especially if you're driving a heavy load such as 4 ohms or less. If you're running several speakers on this unit, try scaling back to just two speakers for now, and make sure these are 8 ohm speakers. Play the unit for a while and see how it does.

First, NEVER turn the volume all the way up to see what's wrong. If HALF volume doesn't work you're only risking a catastrophic speaker blowout if you should suddenly flick the switch that's causing the problem with FULL volume on.

Look for the MUTE or Volume +/- controls on the remote and indicators.

Could be caused by feedback from the speakers being to high in volume.
Hope this helps. Bud
