Sound I like the sound at 10, which I set every time I turn on the system. I cannot get it to stay on ten. when I turn the system back on it reverts back to 18, which is too loud. How do I set it on 10 to stay after shutting power off

Re: Sound

There are several complaints in FIXYA and they are all about this same fault condition....the volume is too high when turned on...

Because of the high number of complaints about this same fault I would suggest that its a manufacturer fault.

So the manufacturer should be contacted about it to ask for your money back..

What ohm and watt speakers can I use with a craig CM402 cd am fm player? It came without them

Speaker requirements are likely to be 8 ohm, most modern hi-fi speakers are. A few low-fi systems have used special high impedance speakers and the old hi-fi standard for valve amplifiers was 15 ohm and 3 ohm or lower has been used in televisions a lot.

4 ohm speakers are commonly used where a higher power output is desired at the cost of some quality of sound reproduction but depending on how the sound is listened to can soon overload some amplifiers primarily designed for 8 ohm as it will try and deliver more power into the lower impedance speakers and perhaps exceed the rating.

8 ohms is a safer choice. The lower the wattage rating of the speakers the more efficiently they tend to be able to reproduce sound at low volume levels so for background music in a small domestic environment the average power requirement will be in the order of half a watt so even with a high powered amplifier the volume would rarely be turned up above 1 - 2 on the typical scale of 10 and ten watt speakers would be more than adequate. It is unfortunate that it is almost impossible to obtain quality speakers rated at such an unfashionably low power rating.

With the stiffer cones of a higher power rated speakers the volume has to be turned higher before the speakers become efficient and listening at low levels can be difficult. In a domestic environment a 50 watt rating is perhaps the best compromise as if there are neighbours to consider a ten watt average power output will be sufficient even if the amplifier is capable of higher powers. Just don't turn the volume up more than necessary.

The greater the power rating the more power will be required for efficient reproduction. For electrical and mechanical safety of the speakers the rating should exceed the maximum output of the amplifier but listening at low levels with quality of sound can become virtually impossible.

It is all a matter of taste and environment.

After a few minutes of playing a cd or the radio, the speakers make a thumping/crackle noise and the music stops. The stereo stays on. Just stops playing music. Any ideas?


OK, this is just a suggestion, without analysing the unit myself.

From my experience with these type of units, it is usually overheating of the IC's on the circuit board.
You can do another test just to double check. Turn the unit off, unplug it from the wall supply for about 10 minutes. Then plug the unit back in and turn it on. Now turn the volume very high, without the speakers starting to distorted, where you can still hear a clear sound.

Now, if this is an IC overheating, the sound should start distorting and cutting out. This is actually a very common occurrence with these types of players as well as receivers in general.

Try the above, let me know what happens.

Also, please do not hesitate to let me know if you need any further assistance.

Kind regards

Can't get video to work so bose works with tv sound

We fixed it. We had everything hooked up right, but - stupid us - we didn't turn the sound off on the TV. Once I turned the TV's sound setting to off, I flipped the speaker switch a few times on the Bose remote, then turned up the volume on the Bose and it worked.

Unit keeps turning off

I had the same problem with my unit (The Harmon Kardon Play & Go was turning off after 10 minutes. It was very frustrating.). It ended up that my auxiliary input jack was not plugged in all the way, and only one channel was being played. Apparently, the unit detects whether or not sound is being played, and it turns off after a certain amount of time if no sound is detected. Also, apparently, that detection circuitry is only on one channel -- not both. So if you don't have the input wire plugged in all the way, the unit does not detect sound properly.
To solve the problem, make sure that the input wire is plugged in ALL the way. :)
Other than this little issue, this unit is fantastic! Highly recommended.

No sound

Have you checked if this is only when you play CDs or also if you play Tapes or Radio? If sound is not present even if you use radio and tape, then the sound output IC is blown, and needs replacement. You need to see a professional technician for this. Also, see if your speakers are connected properly. Then try to connect another set of speakers (borow from a friend) and see if sound is audible. If yes, thn your speakers are faulty.

it must be some bad connections or loose wire. when you connect and disconnect the earphones, it is possible that it created a small electric reaction that slightly welded the wires, and thats how it worked for a while, but the only permanent solution is fixing those bad wires.
