Where to order cords


Any Hi-Fi store will be able to provide them. Amazon have a good selection of cables and wires. As with all cables and wires with hi-fi the better quality sound you want the more expensive the cables you need to get. But it's your choice. You will need to specify which cables you need, based on the connections between your hi-fi and the Receiver.

Bose 321 sound fading


Try the following:

1) Switch the unit off completely, using the powerswitch on the back of the bass box.
2) Switch the unit back on via de switch on the bass box.
3) The display should read BOSE 321 and than be dark.
4) Insert a CD and switch the unit on with the remote by selecting the CD/DVD mode.
5) When the sound is now OK, it means that you need to contact Bose to ask them for the latest software update for your unit. After updating your system. The problem will not reoccur.
6) in case the problem continues and at start-up using a CD, no improvement of sound is heard, the system should go into repair. Contact Bose in your country and ask for return instructions.

I have a Th-C50 home theater and lost my subwoofer system cord, can I use a regular s-cord to make that connection? or is it useless with out the cord?? Please help!


Hi,

Yes you can use any 2-core cable to carry the bass signal to the subwoofer. As the bass speaker cone is the largest cone in your speaker set I would recommend a good quality cable of decent gauge (thickness) to carry the bass signal.

You just need to make sure you have the right connectors for the amp and sub and make sure you connect positive to positive and negative to negative.

Hope this helps,

Chris

Little or no low frequency (bass) sounds


It does not die with age, something has failed. Either the speaker or the amp or preamp for the bass. Who told you it dies with age?

Sound cuts out from time to time


Hi, your system has some problem on the bass module which overheats the thermal sensors built in the bass module/subwoofer. I recommend that you bring the bass module to the Bose service center near your location.

That is the only solution...

Bose lifestyle no sound


Hi, best practice when troubleshooting a no-sound Bose Lifesytle system is to first begin with the internal sources (i.e. the AM/FM). Bose Lifestyle system when connected properly (media center and bass box via the data cable) should show a steady green light underneath the bass module. Begin by simply playing AM/FM tuner and try to increase the volume till 45 (normally the sound becomes audible at this level). If the system still has no sound, then try to check if the bass module is steady green. When you see a blinking green LED (slow green) then do kindly check the DIP siwtch (red latch switch with white mini switches) just beside the Light and data connection. All of the switches should be in "ON" position (basically toggled upwards with the arrow marking indication). Before changing DIP switch settings do ensure that the bass module is not connected to the electrical power. after ensuring that all DIP switch are in the "ON" position, connect the data cable firs and then power up the bass module. Then you should see the bass module blink green twice and once you turn on the nedia center, the green blinking should turn steady green. That should sort out your problem.

Also do note tha this procedure applies only to Series II Lifesytle System and does not include the Series IV (with the smaller bass module).

If all still fails, there is an internal problem with the bass module which would require servicing.

Hope this helps!
