Using the System menu

Changes to system options are typically made only once. If your system operates as you want it to, there may be no need for any changes. In some cases, however, changes are required to make the system fully compatible with the installation options you have chosen.

Viewing and using the System menu

Unlike the source Settings menus, the System menu only appears on your TV screen.

Turn on your TV and select the correct TV input to view video from your 3∙2∙1 system.

on your remote, press the system button. the system menu appears with "audio" options selected, showing a list of the audio options that can be changed. entering the system menu will cause any dvd or vcd to pause.

on your remote, use the arrow buttons on the navigation pad to move around within the system menu, and press enter to select an item. any item that you select will then be highlighted in yellow within the menu.

at any time, you can press exit to leave the menu.


These options affect the way the system sounds in your home.

system options settings and descriptions
bass compensation
  • default setting: 0 (options: -14 to +14)
  • zero is for standard low-tone performance.
  • - decreases and + increases these low tones.
treble compensation
  • default setting: 0 (options: -14 to +14)   
  • zero is for standard high-tone performance.
  • - decreases and + increases these high tones.
audio processing
  • default setting: automatic (option: user adjustable)
  • automatic keeps bose® processing as the standard.
  • user adjustable allows some processing options (movie eq, range compression, mono decoding) to appear in settings menus.

input levels:

tv analog or digital


cbl∙sat analog or digital


aux analog or digital

  • default setting: normal (options: -6, -3, +3, +6)
  • decreases or increases the volume level setting for the input of a connected component. this minimizes abrupt volume changes when you switch from dvd or fm∙am audio on the bose media center to audio from a connected component.


note: to match am and fm levels, or tv channels which can vary depending on the station or program, adjusting the volume on your audio component may be preferable.


When using an HDMI® connection, some options in this menu may not be available, or may not be adjustable. This is because HDMI senses your TV capabilities and sets the option automatically.

  • widescreen tv aspect ratio 16:9.
  • full screen tv aspect ratio 4:3.
dvd image
  • default setting: modified (option: original)
  • modified allows the bose system to adjust the images on some widescreen dvds to fill a 4:3 tv screen. this is done by removing the black bars on top and bottom and by cropping the sides of the image. (many dvd images, even widescreen, will still appear with black bars on top and bottom.)
  • original tells the bose system to keep the image in the original format of the dvd. a widescreen dvd image will have black bars on top and bottom.


note: this option is not available unless you have selected "no" in the widescreen tv option (above).

  • ntcs is correct for ntsc (us standard) monitors.
  • pal is correct for pal (european standard) monitors.
  • (multistandard) is only for a tv that supports multiple formats (ntsc and pal).
video black level
  • default setting: normal (option: extended)
  • normal is the screen black level generally appropriate for most tvs.
  • extended darkens the intensity of the black onscreen.
progressive scan
  • default setting: off (option: on)   
  • off setting: screen image is displayed as an interlaced signal (480i).
