No audio from product
If your product seems to be set up properly but does not produce sound, try the following:
Be sure the audio input cable is connected properly.
The audio input cable that connects the media center and Acoustimass module may have come loose or is connected incorrectly. For more information on system connections, see Setting up your product.
Be sure the system is set up properly and all connections are secure.
A connection may have come loose or may be connected incorrectly. For more info, see Setting up your product.
In the TV menu, look for applicable audio/sound settings.
Many TVs have a menu setting that allows audio to be sent to speakers other than the TV speakers. In the TV menu, navigate to sound settings and look for a TV Speakers or Audio Output option (or something similar). The TV speakers may need to be turned off and the output may need to be set to Fixed or External Speakers. (Tip: If there is no fixed output option, you might need to turn up the TV volume to max to hear it through your Bose speakers—even if the TV speakers are turned off.)
Check the volume level on the Bose system.
When the system is turned on, its volume slowly ramps from zero to the last level used. If the system was turned off at an extremely low volume, it ramps to a moderate volume level. Pressing the volume button during this process sets the volume and stops if from ramping. If a higher level is desired, increase the volume gradually.
Be sure the power switch is turned on.
On the back of the Acoustimass bass module, check that the power switch is in the On position.
Check that that the correct audio input source is selected.
If multiple audio sources are available or connected, be sure the correct source is selected. For example, if the audio device you want to hear is connected to the auxiliary input, be sure that input selected.
Check that that the correct audio source is selected.
Since there is more than one audio source built-in to your system (i.e. FM and AM radio), be sure the source you want to hear is selected on the system.
Check the dip switches on the Acoustimass module.
The four dip switches on the Acoustimass module should not be moved at any time. Check to see that they all point towards the speaker output jacks.
Reset your system
A reset is used to correct occasional product issues. It is not something that a product should require repeatedly. For more info, see Resetting your product.
Check if the light is lit on the Acoustimass module.
The connection panel on the back of the Acoustimass bass module has a status light. When receiving power and connected to the system console, the light should be lit. If the light is not lit, be sure it is correctly and securely connected to both power and the system console. If the light is lit, see Understanding LED indicator status lights and information for more info.
If your bass module was replaced with another unit, determine if it has a dual-voltage switch.
A dual-voltage bass module will have a red switch near the power jack indicating whether it is set to operate on 115 or 230 Volts. If your bass module has a dual-voltage switch, be sure the correct voltage setting is shown. If you need to change the switch setting, unplug the bass module power cord, change the setting, then reconnect the power cord.
If your media center power supply has a voltage switch, be sure the correct voltage is selected.
On the bottom of a dual voltage power supply, there is a 230V/115V switch. If your power supply has this switch, disconnect it from the power outlet, set the switch to the voltage used in your region, then reconnect power.
Check the condition of the audio input cable.
Make sure there is nothing broken inside either the mini-DIN or the RJ-45 connection. Check for any kinks or cuts. Make sure it has a strain relief where it connects to the Acoustimass module. If there is no strain relief or the cables or connectors are broken in any way, replace the cable.
Be sure nothing is connected to the headphone jack.
The speakers are automatically muted when headphones (or any cable with an 1/8-inch stereo plug) are connected to the system.
Check the condition of the speaker wires and be sure they are secure at both ends.
Check the speaker wires for any kinks, scratches, cuts or damage. Replace any damaged wires and check that they are securely connected at both ends.
Try another input on the Bose system.
The input may be defective; try another input (it is ok to use a different type of input, for example analog instead of digital or digital coax instead of digital optical). If the problem only occurs on one input, that input may be defective. Follow the link below for more information on how to service your product. Depending on your product and region, you will be provided a contact number or the ability to setup service online.
