Effects
The effect button is used to select the type of surround sound or audio technology you want to use with a
particular input. In many cases, the control pod will recognize what audio technology is streaming from your
audio device, and will automatically select it.
For example, if you are watching a DVD and have selected the Dolby® Digital 5.1 stream on the DVD, then
when you select the DVD audio input, Dolby® Digital will automatically be the selected effect. The control
pod will default to the last effect used by whatever input source you are using.
You can use the 'effect' button to select a different audio technology if you wish to change it. Note that not
all effects are available for all inputs (refer to the table):
Repeatedly pressing the 'effect' button rotates through the available options for that type of input. If only one
effect option is available, then the effect button will have no impact.
Whenever the input or bitstream changes, the previously selected effect will be automatically re-selected. For
example, if you select Dolby® Pro Logic® II while listening to the 6 ch. Direct input, 'Dolby® Pro Logic® II' will
be stored in memory for the 'Direct' Input. The next time you select the Direct input, Dolby® Pro Logic® II will
be automatically selected as the effect.
When returning from Standby, the previously selected input and effect will be shown on the control pod.
Each effect is described on the next page. For more information about surround sound and other digital
audio technologies, visit www.logitech.com.

Adjusting Volume and Other Levels
To adjust the main volume, simply rotate the knob.
To adjust your trim levels for the subwoofer, center channel, or the surround (rear) speakers, press the 'level'
button to cycle through them. For each one, rotate the knob to adjust the level. Note that each level setting
is a "global" setting, meaning that the levels will remain the same regardless of what input or effect is
selected.
The LCD will return to its previous state if left alone for 5 seconds.
