Too little bass or too much treble from product | Acoustic Wave® system II
If the sound lacks bass or has too much treble:
Try the following:
Relocate the system to increase bass.
Sound characteristics change depending on location and environment of the sound source. Moving the system closer to a wall or corner, or placing it on or near hard surfaces, increases bass response.
If listening to an AM or FM station, be sure the Talk Radio mode is set properly.
Talk Radio mode reduces bass on AM and FM radio, which can help with voice clarity during talk radio programming.
While listening to an FM or AM radio station, press the Play Mode button on the remote control to turn Talk Radio mode on or off. When enabled, the display shows TALK RADIO (or TALK RADIO – ON) to confirm the setting.
Tip: Talk Radio mode automatically turns off when you switch to another audio source or station, or when the system is powered off.
Note: On products running software version 040401 or later, Talk Radio mode is replaced by Bass Reduction mode, which affects all audio played through the system. For more information, see Adjusting the tone controls on your product and Checking the software or firmware version.
Try connecting a different audio device.
If available, connect another audio device using the same cables and connections to determine if the issue is related to the first device or its settings.
Try a different app.
If the issue only occurs with a particular app, it is likely related to the app or app settings.
Replace the cables used to connect your product
Try replacing the cables that connect your product. If no issue is heard with new cables, the first set of cables is the issue.
Determine if the room size is too large or the distance from the system is too far.
The volume from the system will seem lower in larger rooms than in smaller rooms. The level of sound will decrease when heard from greater distances. Try to place your system within 20 feet (6 meters) of the listening area.
If connected, bypass any adapters or extension cables.
If your product connects to the device using an extension cable or adapter, disconnect the extension cable or adapter to determine if the issue is related to it.
There are no adjustable tone controls on your Bose product.
Equalization, like bass or treble, is not adjustable on your product. You can try adjusting equalization on the connected device, if available. Try adjusting in small increments and check if the audio sounds better or worse to you. (Note: Greater adjustments can also impact volume level, which could create distorting or crackling audio.)
Reset your product.
Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more information, see Resetting your product.
