Question about Bose Companion 3 Computer Speakers

2 Answers

No audio The speaker system was powered up for approximately 2 weeks uninterupted and unattended. They were not being used, just powered up. When I attempted to play music through them, they would not play. I do here slight crackling in the speakers when I unplug and plug them in. This happened once before and powering them down and back up resolved the problem. Now nothing. Any ideas? Thanks in advance. Bob

I had a set of companion3 speakers with no shound and it turned out to be the volume control module that sits on the desk and you rotate it to turn the volume up or down, and touch it to mute it. Bose replaced it for free.

Will i be able to swap the original speakers of the J520 with a pair of Sony SS-B1000, without causing damage to the new speakers? the Sony SS-B1000 has an Impedance of 8 ohms, and peak power of 120 watts.


Hi, As long as you like the way the speakers sound there is really no reason you cant use whatever speakers you want. To find out the approximate wattage of the stereo you are using look on the rear of the unit and you will find a tag that has " SPECIFICATIONS " on it. There you will see perhaps the a.m. and f.m. frequencies it's capable of receiving also there should be numbers saying something like" 100-240vac or 100-240v~ 50-60hz 1.2amp or 120watts.( if power is listed in amps only-1 amp's equivalent to about a hundred watts)Dividing the wattage by 3 will give you an approximate power out put. Example if your stereo draws 120 watts worth of 110 from the wall it will put out approximately 40 watts to each speaker. Changing from OEM speakers is all right as long as you don't try to hook up some 150 watt peak speaker to a stereo capable of just, say, 10 watts per channel. Doing this will eventually cause damage to the amplifier, not to mention causing about 30 percent total harmonic distortion-which take my word for you will know if you ever hear it! So long story short-use what you wish, just be careful not to overload the receiver-if the speakers are a bit to powerful for receiver you can lessen distortion by turning down the " BASS" as that takes the most power in a speaker. Thanks for choosing FixYa, I hope this helped-good luck, Prodzilla

It keeps shutting of and the power light just flashes if there is too much bass? what do i do? the volume is low to begin with


Hello, the protect circuit is likely detecting a damaged speaker or speaker wire.Check the unit with one speaker at a time connected, or if you have an ohmmeter measure each speaker they should read approximately 8 ohms.When you connect a speaker thats bad the unit is designed to shut down and flash protect.

Power button turns green, flashes and then turns red and flashes.


Hi,
While working it stops and flashes red approximately 2 seconds interval

Causes
Protection circuit is activated depending on the temperature of the surroundings

Remedy
Switch off the power supply and power on after the temperature have reduced.


While working it stops and flashes red approximately 0.5 seconds interval

Causes
1.Using speakers having less impedance than the specified.
2.If speaker core wire touch each other Protection circuit is activated


Even applying power red flashes 0.5 seconds interval

Cause
Amplifier circuit has failed

Remedy
Switch off the power and contact denon service centre


Thank You

My amp keeps goin into protection

The volume is either set to high or the speaker load is to low of an impedance. Remember 2, 8 ohm speakers connected is the same as 1, 4 ohm speaker. Another possibility is that you do not have enough battery power coming to the amp itself. A simple rule I use is take the watts and divide by ten, that will give you an approximation of the amps needed on a 12 volt system. This takes into account some of the losses in the amp, but it is only an approximation. For example 300 watts RMS is 30 amps, which will require a number 8 wire to keep the losses at a minimum. You can check wire drops on the web.

Good Luck,
